Hello Ladies and Gentlemen!
I am fairly new here, I hang out over on the HFT and spend most
of my time there. But I always read the DIY forums due to the fact
that there is such a large group of people from all around the
world. There also happens to be so much knowledge here that it
truly is astounding. Ok enough flattering your pants off!
I know a sub isn't the greatest accomplishment in history but I may
as well share it and get some comments.
The enclosure is 14"H x 14"W x 15"D constructed of 3/4" MDF
no screws just glued butt joints and two internal braces placed
off center tying all of the walls together. Stuffed with 50% Polly
Fill and of sealed design. The feet are 1.5" ^2 Oak with billet
aluminum tips. The amplifier is a Bob Carver 500 Watt RMS TDC
Sunfire that was meant for the Acoustic Research ARS500 OEM
Sub. I bought this amp cheap off eBay brand new from a surplus
outlet ($54.00 USD) it is meant to run on 240 European voltage
but has a flexible input cycle so it can run 50 or 60Hz.
Lucky for me I have a 220V circuit right where I needed it!
The driver is a Stryke Audio AV-12 with 23mm of one way linear
excursion (all T/S Params are Dumax tested by Stryke) These
drivers were manufactured for Stryke by TC Sounds.
The results to my ears are seamless integration with the mains.
The sub does not call any attention to it's self, rather it's mostly
invisible as it should be!
Here are some images of the construction:
The finish is Parts Express Vinyl Laminate (Black Ash). This finish
and this enclosure are temporary. I am going to start a Line Array
project very soon and the ultimate goal is a pair of AV-12's in
sealed enclosures (.5 Q) running Stereo Bass off a Pro Amp of
some sort (QSC or Crown) with 500W Rms x2 Channels)

AudioFanatic,
I am not sure I would go as far as saying it looks as good as REL
but you certainly have me blushing! Thank you for the compliments!
As far as design I had bought the AV-12 to use in an enclosure
similar to this one many months ago. Then I decided on using a
dual AV-12 setup but I was waiting untill I had my Line Array's
before doing the sub enclosures.
I came home from work Saturday Morning of last week (I work
steady 3rd shift) and I had all intentions of going to sleep. Then
for some odd reason I got the bug to drag the table saw outside
and make some MDF Dust.
A few hours later this is the result of my dust making adventures.
I have no plans on keeping this particular enclosure in my setup
permenantly. After I have my main speakers built then I am going
to see how much floor space I have to play with and build my
Stereo Bass dual sealed AV-12's. I will probably go with a slightly
larger enclosure when I do the new boxes.

I ended up grabbing the same amp as Brett after I found this thread so I thought I'd post how my project went
I had the somewhat crazy idea (joke suggestion by friend initially) to turn my living room closet into a subwoofer. So one weekend, my roommate and I went out and bought a new solid-core door and did just that. Amp and 2x15" woofers all mounted in the door. Sealed around the door with weatherstripping.
Here's a pic:
http://siliconice.net/nuke/modules....ame=gallery&file=index&include=view_photo.php
The odd part is that the closet is still a closet...door opens for access to the wiring, etc. Not that we really store anything in there anymore, but if we need to hide some junk real quick it does just fine. I meant to do the calculations and measurements for the woofers and box size but I haven't gotten around to that yet...but hey, got it built and it sounds fantastic, far better than I ever hoped for. My towers sound puny in comparison. Not to mention people's faces when they come over

The door does vibrate, some, but there's a lot of power coming from this thing so can't get rid of all of it and still have it be a door....but the weather stripping seals it very tight and keeps vibration to a minimum, plus i adjusted the door hinges and the knob/bolt assembly to be much tighter. It holds the door in place reasonably well.
Tim,
Yep it's one heck of an amp!
Great memory too! Yes I am going to be working on LA's soon.
John Janowitz of Stryke Audio designed the Enclosure/XO's for
his drivers for me. I am just waiting for him to ship all the drivers
and XO parts plus the pre cut baffles and braces (CNC Router...)
He is waiting for the ribbon tweeters to show up..
I will post when I start on them

Here are some photos of John's prototype Stryke Arrays. My set
will be exactly the same, though finished differently.
These arrays use 12 each 7" Woven Fiber Midranges and 12 each
SilverFlute Planar Ribbon Tweeters.
They can be build vented or sealed depending on taste. I will
most likely vent mine and insert a set of port plugs and tune to
taste. I am also building my crossover networks externally in
thier own little jewel boxes with lucite windows. I will have 4
terminals exit the speaker cabinets and when I am ready to move
up to full active crossovers I can just plug them right in.
If you are interested in the whole buildup with FR Plots check

I bought my amp from eBay seller EsSurplus and they are still
selling various AR amps on eBay. I guess when Recoton went
belly up they hawked off all of thier parts inventory and EsSurplus
swooped in and bought the stuff for pennies on the dollar.
There is no better deal than $54 dollars for a 500 RMS amp!
