I'm waiting for a chance to get it back in the spray room.
Maybe another couple of coats this weekend.
I should be listening to it in a couple weeks.

i don't see any reason why you can't rub that finish out to mirror...if you wish...look'n really good so far.

Listen. It's All Good.

Thanks Man!

I may try that on the amp box or shelves first.
Can you recommend a polish for lacquer based paint?

GOT THE BOX DONE!!!!!!!!!!!!!!!!!!!!!
Overall, I'm impressed with finish, the design, and the sound.
Eventually, I may try some polishing compound to try to mirror the finish a little more.
I've had the sub in a pre-fab Bassworx box 1.65cf tuned to 42hz since I bought the plate amp, and it sounded better than my 10" Cerwin Vega.
Put the sub in the new box, and WOW!! what a difference.
I'm feeling notes that I never knew were there. The SA240 really pushes the sub to its limit.
It doesn't shake the walls down, but its more than enough for my condo.

When I pulled the sub out of the old box, a piece of the trim ring came off. D'oh!
I have a blown Kappa, Does anyone know if I could use the trim ring off of that one for this one? Could this be done easily?



Heres some pics.

Bought a flat screen wall mount from Amazon for $55.
Looks like the ones Best Buy sells for $200-300.

I think my next project is to buy a HTPC case so the computer can go in the entertainment cabinet.--------Built that too a few years ago.
Then I'll build a twin brother for the Kappa.

Can anyone recommend a different subwoofer that would go good with this design?

Looks great. What kind of output are you getting down around 20 HZ. That's a big ass box but I guess that's The price you pay to go low.

NOOB Question:

I have a Pioneer VSX-920 AVR.
It has a sub pre-out.
Can I hook up say a Behringer ep2500 to power my sub?
Do Pro Audio amps only work with a pre-amp?

Thanks man!
I wish I had a cool graph to show , like all you other guys.
My ears say its pretty flat from around 17hz-70hz.

After listening for a couple months now, I'm wishing that I got a Behringer, and
built something for a 15" or 18".
I hooked up an old Memphis 15" (entry level) sub in a like 1.5cf sealed box,and
it was a whole lot louder---didn't sound as good as the Kappa, but in a different
box I think it would.

I run a Rockford Fosgate T215D2 in my car right now, that I want to use for my home theater.
I've seen people run W7's, XXX's and Sundowns for home theater, but haven't seen a T2 yet.
Does anyone think it would make a good HT sub?

here are the t/s parameters

your ears can't know if you are flat to 17hz. Get some measuring hardware/software

cool project though!
