68 liters tuned to 21 hz.
HPF changed to 17.7 hz with 1 db of boost at 25-30 hz.
Sub at Xmax with 300 watts.
One 4 inch port 29 inches long.
Maximum air speed is 26.8 m/s at 20 hz.

Dropping the tuning to 19 hz ends up with you giving up more then you get in my opinion.

Rodny -when following your links I'm getting a error message that says:

No sub pics.

Wow, alot of people working on 10" sub projects. Looking forward to seeing the finished product. Your work is always top notch.

Nice pics!

Front sub and port with the amp on the back is what I would personally do.

Re: another css 10" build

The Bash 300 has various combinations of HPF's and boost by changing 2 resistors. The factory default settings are 17.7 hz with 1 db of boost at 25-30 hz. Lucky you, you're plug and play!

I agree with this man! Although I might be biased...

Rodny, whatever you do decide, I'll be following along closely to see how yours turns out. 68 Litres... what's that, about 2.5 cubes? that should give you a great sounding sub. My volume constraints will definitely impact my end results, but I wanted to build something smaller this time. I think with a sub that size you should easily be able to fit the driver and port on the front face. What are you porting with, 4 inches?

Did you have any design ideas, or are you open to any kind of suggestions? I guess it would depend on what the rest of your room and speakers look like, and how important it is that the sub mesh into the decor. What about finish? Wood, or paint? Standard big black box? (I'm now living vicariously through your project).

Hey Bartley!!

I was thinking about doing a slotted port, I want to know what you guys think?
If not I stick to 4" x 29" port this would be easier.

I have some bright red paint that I was going to use on my motorcycle but sold the bike so I have the paint, its a two color, you have spray the silver first and the red and then the clear, I don't have to match the color to my room because this project is just for fun, I just wanted to build a sub:dumbcrazy: it might end up with a different color:bigsmile:

Do I need to sealed the amp from the sub or not??:dontknow:

Re: another css 10" build

It's a "good" idea to seal if you can, but not totally needed. If the amp is sealed well to begin with then you'd benefit from boxing it by protecting it from the pressure waves from the driver - might be overkill in this instance.

boxing in a plate amp can very quickly eat up precious cubic inches - I'd suspect that the Bash 300 is sealed well already.

I did, however, never box in my ADA 1200 plate amp when it was inside my AS-15 Klone.
I had put it in a separate enclosure for the Heretic II and it crapped out on me... The best laid plans, huh?

(BTW, the ADA 1200 is repaired and should be in service in another week).

Re: another css 10" build

The Bash amps don't need to be separately sealed from the sub cabinet. Whether you do a slot or round port, just remember the amp requires 3.5 inches of mounting depth.

Re: another css 10" build

The only modification I was considering for my amp was adding another thin layer of gasket tape around the edge. The amp comes with some, but I may add some more, depending how it feels on the test fit. Boxing it in wasn't an option for me, since I needed all the volume I could get.

As you saw, I was close to going with a slot port, but decided to keep my 3" precision Port since it was a bit too late to revise my design. If you're building a fun project, maybe it would be good to experiment with a slot? I saw some nice looking Velodynes the other day that use slots, and it's certainly something I could live with. How about painting the box in a dark colour, but doing the slot in your motorcycle red, kind of like a big mouth? :1eye:

Re: another css 10" build

I got the amp yesterday so its time to start the project.

2.4cft plus port, speaker and amp, tune to 21hz, slot port 2"x6"x27.5" long :bigsmile:

Re: another css 10" build

That sounds like its going to be a great sub. Not really "big" in the grand scheme of subs, but certainly big enough to coax some performance out of that solid little 10-incher. Have you settled on the final dimensions and shape, or just the volume?

Wait... are you going to get crazy with this thing and make it as great looking as your IB manifolds?

So far the dimensions are 14"W, 18"H, 28"D, little over 3cft, I haven't decided on how many braces so the air space might change a little, I want to make the port removable just an case I want to change the tuning:coocoo:, I think I'm going to build two boxes one will be black and the other red:devil:, the same shape maybe one with round over bit and the other with a chamfer 45 or 30 degree bit or maybe mix:dontknow:, just want to build something cool and sexy:heehee:.

The paint its going to be automotive two stage, so it will be shiny:bigsmile:

I have some 3/4" Plexiglass so it might end up in one of the boxes with some neon:dumbcrazy:
