The RL-p's were based on the TC-9 motor, but a second spider was added and the tinsels were woven into the front (closest to the cone) spider. I don't recall if the more recent iteration TC-2000 is the same but if Sonnie says so...
Well... nearly three months later Cedar Creek Cinema (the second time around) is finally finished.
I did get the other Pulse sub built and it is exactly as the first one. I decided to leave the feet the same and stand them in the corners.
The finish is Kilz primer, Valspar textured paint and Olympic flat black latex enamel. It is not near as fine as my Behemoth finish was, but it worked out fairly nice. I am sure Rodny could have done a better job finishing it, but he skipped country on me. :huh:
So what does the response look like in the new HT room?
Of course it is combined with the Fi Riser Q18's, so it ain't a standalone measurement, but I did measure nearfield driver and port...
Wow! That's all nice stuff Sonnie. I'm impressed, your HT room and setup have started me thinking about a complete room for myself. Others I've seen haven't done that.
Looking at the FR curve . . . . . I'll bet things rattle when you're up over 110db @20hz and below.
You know, I was wonderfully surprised when I heard zero rattles. There was hardly a thing that did not get glued, caulked, screwed, nailed or stapled down where it would not rattle... or cause unwanted noises. Of course, there are vibrations, but just not the noisy kind, thankfully. We pushed the subs pretty hard with Cloverfield at about 120db and we were vibrating ourselves. I could feel it like I have never felt it before with bass... remarkable to say the least. I am looking forward to a small gathering/meet of AV enthusiast to show off the system. :whistling:
And your brain:run2:
120db - WOW, even in that large room you probably fell the compression!!!
Seriously, very impressive sub build and room you have. Love your setup! Now if I can just find a bigger place to do the same...
I trace/draw out the cutout areas and then use a combination of hole saw and jig saw to cutout the beginning pattern board. I then lie all other boards on top of the pattern board (screwing it down) and use a router to cutout the same areas on the new board. It is a dusty job and takes a while, but it gets all the brace cutouts identical. I then route all the edges of the cutouts with a round-over bit.
I never have figured up the cost, but I suspect it would be around $800-1000 or so for the driver and materials, unless you could catch a good deal on the drivers, which have been known to surface all along.
The software used to design it is WinISD... we have a Sticky Thread that explains the use of it and where you can download it from.
Thanks...I am trying to build subs and speakers, so I am just looking at what everybody else is doing and gathering some info. I am 16 and I just bought some klipsch XF-48's, so I owe my parents about 1000$'s still, so I can't build anything yet .:crying:
I thought about building a sub using an audiopulse driver, but the idea's still fermenting in my head.:scratchhead: Very nice enclosure, must have taken a long time to build and cut. How much cubic feet of air is their in that enclosure?
I would like to build the LLT. I will be using the Ultimax 15" DVC. Also have (4) 4" x 18" flared ports to use if necessary. The enclosure will be behind the couch so it will have to be narrow 18"/20" but up to 30/32" tall and 50/60" long. Recommendations for speaker/port location would be...
I should have taken more pictures of this build, but I did most of the assembly in a hurry one night after the rest of the family was in bed. Anyway, I had a full marty with a Dayton classic 15 that sounded amazing but I was suffering from massive room gain in one corner and the inability to...
Hey guys, so budget is a limiting factory for my build its a 500mm cube I don't mind ported or sealed but need sub 30hz(my mains comfortably get to about 35 before they roll off too steep)
I am in the UK so somthing available here would help as I would have to spend on shipping & import duties...
Another build helping my workshop friend with his cabinets.
Mainly music but maybe movies in the future.
Drivers: Eminence Lab 12
100liter probably around 90liters usable.
Ported optional Sealed.
Dual 4" ports.
Tuned to 27hz.
Portspeed below 15m/s
Highpass Bessel 3order 20hz.
