Rythmik DS1500s - building two
The beginning, September 08
I begin my journey into DIY speaker building, although this is not my first time. Either way, research is the key word here. I begin researching all the different types of subwoofers out there. Even though I knew I wanted to build my own I carefully read about ready-made subs as well. I followed up on all suggestions by friends and any suggestions on the web. Especially those discussed at the Shack. After much reading about who was raving about what I decided to go with a servo sub. Further I decided to go with 15's, just in case I needed the extra SPL :bigsmile:. They will be a 3 cubic foot sealed enclosure. The DS1500s model. The external dimensions are 18 inch wide, 22.5 inch deep and 26.5 inch high. I will be using three quarter inch MDF. For the price, Brian Ding has the best. Brian runs Rythmik Audio. Ikka described the sub as ‘dry’. To me that means you can feel the bump of each sine wave. No mush at all. Also, these subs are touted as being some of the most accurate out there. I don’t like just ‘more bass’ I want clean bass. For that reason I decide that I am going enclosed. The last subs I built (about 14 years ago) were ported and I always felt there was room for improvement.
Here are some pics of my original subs. I made them look like Greek columns as I liked that look, and tubes get rid of alot of bracing issues.

4 months later (Early March of 09)
I have spent months off and on reading about all the different types of subwoofers out there. The options are daunting. I am still gleaning that Rythmik Audio stands out for what it is competing against. I don’t have 3 grand to spend on a single speaker, but from what I read, Rythmik Audio subs can compete with far more expensive subs. that’s all I need to know! I have the go ahead from my wife to spend the money and make my purchase. Brian was very nice to work with on the ordering.
One week later
The subs arrive. Large boxes but they fit into my Golf readily. One was a little crushed on the corner so I opened each box and inspected everything before leaving the post office. It was all packed quite well and all the items looked good. When you purchase two and pay by check, you get discounts. Although you have to wait for your check to clear, the discount (for me) was worth it. Both subs were a total of $1100.
I think the speaker looks awesome
The amp is exceptionally heavy
Day 1
Purchase MDF from home depot. Set it aside in the garage. three quarter MDF is very heavy.
Day 2
I spend the evening drawing out where on the MDF boards I will make my panel cuts. I am building two subwoofers, so everything is double. The panels are horribly heavy and I am doing this project by myself. I work it out so that I can cut each of the ¾ inch MDF boards into 4 sections each. Then I can cut each ¼ section into two panes each. Each ¼ section is very easy to lift and feed into my radial saw. This is very important as I predict it will help me to get slightly more accurate cuts by not fighting a large section of MDF.
Here is my scritching, my modest attempt to keep things organized
Day 3
Today is my first day of actual building. I pull out onto the lawn one of the ¾ inch boards and begin cutting it into fourths, per my drawings. Each fourth board is quite easy to tote around and feed into the machine.
For today, I am able to cut all the major panels.
I also get the main baffle piece cut.
This is the Radial saw I used
I am then able to assemble the pieces together and complete both boxes. I use one inch and a quarter deck screws to hold them together. I realize that glue alone will work, but I don’t own a bunch of clamps and waiting for the glue to dry takes quite a while. They are now glued and screwed and slowly drying. I did not cut the circles for subs themselves yet. All this took me the entire day, about 10 hours.
Here is the test fitting of sub number one
Just before gluing it shut, my cat performs a quick quality control check
The screws cause the glue to eak out
A slightly better shot
Here are both boxes, only the bottom panels are missing
Here I am figuring out where the amp cut out goes

Test fit with the amp
Day 4
Today turns out to be baffle day. The plans from Rythmik are nice and detailed, but cutting each piece and hand fitting them all into each box ends up taking the entire day. Today I spent roughly 11 hours. First I measure each cut, then I cut the holes in each baffle piece, then I route out each hole. On this day my friend Quentin stopped by and helped me with the routing
This was by far the most detailed workday. By the end of the day I was a little burn’t out from all the cutting and sanding. After today, it will be mostly assembling and minor cutting. Although I still have to figure out how to cut the 14 and 15 inch speaker holes. Remember, I have no wood workshop as I see in so many posts here, but I have a few key tools and a bit of creativity.
Here the main baffles are cut
These are the side baffles as outlined in the Rythmik pdf
These are the other side baffles that make up the entire baffle system
Before cutting all the circles in the baffles I run a test fit
Various pictures of cutting the circles in the baffle pieces
Day 5
From this point on I will only have a few hours at a time to work on my speakers. So on this evening, I once again test fit the inner baffle panels and begin gluing them in. Along the way I add the sound deadening polyfill. Today I only get the top third of the baffles in along with the polyfill.
Here are all the pieces together in one shot. My inspectors don't miss a beat.
Here goes the pollyfill and the primary baffle
An extra layer of polyfill for the top of each sub. I hope a little glue will hold it in place
I fold it in half to slide it in
Day 6
With just a few hours available, I work on the next level of baffles. Adding more polyfill as I go. I glue the polyfill to the box walls with silicone caulking.
Here are the two boxes finished with baffles and poyfill up to the two thirds level
As I take them to the garage for sanding and routing, I stop to weigh them. They come in at 70 pounds each
Now I am done with routing the edges and sanding the sides
Tried to get a little fancy towards the bottom
Day 7
Tonight I tackle the issue of cutting large circles in MDF. I go to home depot but they have never heard of such a guide for a router. Of course, after building my own I find on the Shack site several recommendations and they all look good. But, at that point I had already made the cuts. This was the first time in the project that I had to re-cut a board. I cut the circle too large. However given the crudeness of what I built I guess something like that would happen. I started over and got the next 4 circle cuts dead on. That took the evening.
Here is my home made router circle cutter
Day 8
Tonight I work on the feet. I found some furniture legs at home depot that if cut down I thought would look good. I had ordered some black chrome spikes that will match up well with their dimensions. Each foot is drilled for the threaded rod from the spike then drilled for the hurricane nut looking thing that the spike screws into and then routed so the hurricane nut will be recessed enough for a flush fit of the spike. Finally I cut the tip of the furniture leg off so that I will have 3 inches of clearance including the wood and the spike. The plans call for 2.5 inches, but I decided to add half and inch. This was the only place that I deviated from the plans from Rythmik.
Here I screw the furniture foot to a 2 by 8 piece of lumber and determine how high to cut it down to
Here is the result, eight feet. Here I have already placed the thread anchors into the wood, and glued them there
Closeup of the anchor
Here I test fit the feet along with the black chrome spikes to see how it will look
Day 9
Tonight I clamp the inner and outer speaker boards together (with glue and screws) then attach that assembly to the box and glue/screw that down. Next I attach the feet I made last night. I think maybe they are too small in width for the size of the box, but at this point I simply move on. With this concern in mind I make the feet attach with no glue, only 2.5 inch counter sunk deck screws so that later I can switch them out if I want to.
This is just before I clamp the inner baffle to the outer baffle. Lots of glue as they need to be as one
Here is the glue that 'eaked' out
Test fitting the speaker!
I think the speaker fits a little to tight. Less than one sixteenth from edge of speaker to outer baffle. Oh well!
Day 10
The boxes are all sanded routed and smoothed out. Let the painting begin! I use ‘Sandwash’, a paint found at home depot. It looks like mud and the final look resembles something like 60 grit sandpaper. I like that kind of finish, so I go for it. I get ‘Obsidian Black’.
Day 11
Another coat of paint in the morning. They are starting to look really good, the color and texture is amazing. Being a thick paint, all blemishes are hidden and they have a texture that is pleasing to the eye. After the paint dries, I swash on a clear coat on. Its says to use a ‘roller of high quality’. As it goes on it seems rather visible, but I figure it will clear up. 4 hours later and the finish looks horrible. Almost every roll seems to show. It has milky white stripes everywhere. I stare at the other sub and think that maybe I should just not give it a clear coat. The problem is that any contact to the paint leaves visible marks. The first time I move it will certainly ruin much of the paint job. So I decide to apply a very thin layer of the top coat and that is when it hits me! I should be using a brush. This was the magic bullet, the finish went on thick and absolutely invisible. The second sub looked great. Now I have to go back and re-paint the other sub as it looks ridiculous. I will let them sit overnight so that everything can dry, glue, paint, etc. I have read that caulking/glue etc, can possibly eat at the speaker surround. So I place a heated fan blower pointed at both of them and let them cure overnight for good measure.
I blow a heater into them for a half day each to dry everything out:
Just had to see one against our 10 inch ported sub that powers our living room 5.1 setup. This was a great lesson on the mechanics of speakers. The little one would go just about as deep and was just as resonant, at low volumes. The only thing the Rythmik had to offer was more spl. I say that, however I was only listening to the radio, I had no REW for backup. I am sure it wont go down to 20 hz. But for radio listening at low levels it was very competitive. For casual evening tv watching it works quite well.
I also have to say that the Rythmik was picking up on some line noise that was very noticable. The little one was competely silent. Once I moved the Rythmik into the basement there was no line hum. Not sure why upstairs has that.
Day 12
I give the re-painted sub a clear coat (matt finish) using the paintbrush, not the roller. It looks just as good as the other sub now. The only difference is that this sub now has 6 coats on it. Oh well!
Finally, late in the day I am able to attach the black chrome spikes and take a look.
I have no idea how you are supposed to attach a 15 inch grill to a 15 inch hole, as you can see I pulled a true DIY here. Had I known that in the end these speakers would be staring straight at me, and not down, there is no question I would have come up with a more cosmetic solution. But after placing these in my home theater, REW told me the best placement was pointing at me. I tried almost two dozen locations.
The finished product! I set each one next to my olds subs for a visual comparison. The new boxes are coming in around 100 pounds and are fairly difficult to move around. But they do look like they mean business!
Sub one:
The subs are not quite black, but they are not as grey as they appear in these photos.
You can see the Crowson under the couch foot to the left of the Rythmik. Don't get me started on how much these add to the movie experiance. Tactile is something that has to be felt to be believed (pun intended!)
sub two:
Day 13 (one week later)
I finally have some time to run a dvd. I was running my old subs with a 15 year old Kenwood and pre-amp. I simply disconnected the 12 gauge wire and hooked them to the Rythmik’s. I was not pleased. It was way to easy to over power them and the bass was no better than what I had built 15 years ago. So I decided to go for a ‘proper’ speaker hookup, meaning attach them via the RCA inputs. This meant also re-wiring the fronts through the Kenwood amp to power them as I needed to run them through an EQ to help prop up their bass. Now however, the receiver was not controlling the balance of the surround set up so getting all the speakers to have appropriate sound levels took some time. I needed to run the front mains through a mixer so I could bring up the 80-150 Hz range. The EQ is some ancient garage sale special, 12 bands per channel. The front mains are 12 inch ported 1970’s technics. The are about 3 feet tall and very heavy. I don’t know if they are good or not, but the manufacturer was confident enough to put a plate stamped on the top showing the frequency response from 20-20. Looks pretty official anyway, also the tweeters look pretty tough. Either way, when I ran REW a few months ago it showed that without equalizer intervention, the lower end was a little weak. My center channel is an infinity center channel. The surrounds are infinity bookshelf speakers that I use as surrounds. My projector is a DLP Sharp 12000-U. DVD player is a Wal-Mart special, and we know Wally only sells the best, right?
Once I had all the re-wiring completed I sat down with “War of the Worlds”. I must say that after some crossover and channel level tweaking, I was very happy. Eventually I got to “Jumanji”. Overall not such a good movie for sound (for me anyway), but when the lion appears and growls for the very first time I was shocked. First, it is a very deep sound, and very clear. A good test of a sub-woofer. I must say that no matter how high I turned up my old subs I never got the furnace venting to rattle. But first pass with these subs and the rattling was so bad I had to take a timeout and fix as much of that as I could and then listen to the scene over again! (and again!) The vibrations in the metal competed far too much with the sound effects. J
I must say that re-balancing the system with this whole new setup took many evenings of tweaking and experimenting.
These speakers have taken the whole listening experience to a whole new level. I am very pleased with the outcome. Also, I have to mention that I bought some Crowson Technology Transducers last winter. My wife must have had a fever when she agreed to that purchase, but she did and it made me very happy! I say that as they run $1500 bucks for a pair. I read for months about that purchase as well. Many reviews stated that with a good enough sub you don’t really need them. Now, I know I did not by some three grand a piece subs, so maybe I speak out of turn here, but nothing can replace TACTILE sensations. Yes, my new subs can make the fabric and very frame of the couch move in motion with the frequency, but having the ground shake from below you really makes the opening scenes in WOTW come to life. Until I can afford three thousand plus subs, I will probly always have that opinion.
Here is my home theater. It is 16 wide 21 deep and 9 high. It is completely unfinished, however I bought $70 worth of black material from Hobby Lobby and hung it on all the walls. The material behind the screen (104 diagonal if I remember correctly) is a photography muslim. The projector is just sitting on a bookshelf and the carpet is just a remnant. Nonetheless, the overall look is very elegant and rich.
I will attach the REW results as soon as possible. Thanks for checking out my speaker build! This has been a fun experiance!
