I like that idea.
I'm not knocking Eric's design as I don't know anything about box design.
I'm trying to find out what my options are. If I can come up with a more WAF friendly shape or size, I'm all for making the wife happy. If I can save a couple hundred dollars in the process and end up with deeper bass and more power in the final product, I'm a happy camper. I don't mean to drive anybody crazy in the process and I'm not knocking anybody's efforts to produce and distribute budget friendly possibilities.
In our case, I'm pushing by adding a third subwoofer to the room's speaker mix. The wife is very sensitive to a bunch of speakers in "HER" living room as she's quite happy with a big screen and a pair of cordless headphones. As it is, anything above -15 on the volume and she's holding her temples with me wanting to add a separate Emotiva, XPA-5 to the mix as I'm saying, "Can't you hear the life being sucked out of the capacitors?" as the action volume climbs in intensity.
I like the idea of assembling the parts and for a few dollars less, having a better subwoofer then one might get if buying direct from SVS, PSA or Rythmik and in my opinion, these guys have great offerings. It can be a 12" or a preferable 15" driver. And if I can creep up on the cost, a driver here, a subwoofer box there, later the addition of a quality plate Amp and then pay a cabinet shop to make it all pretty, I can make this third sub happen.
Extensive room measurements have shown we have a soul sucking null in the 80Hz range which like a black hole is busy sucking the life out of the mid-bass slam and the only fix is going be either expensive, wife upsetting, room treatments (not going happen) or a third sub, maybe hidden behind a corner great chair, to fill in the null.
One thing's for sure, the wife will have trouble saying no to a graph as graphic as that graph is.
I've moved the subs, added an Anti-Mode, 8033S II, stuffed the subs with poly-fill and played with Audyssey until blue in the face but the null is here to stay.
(Cost of carpets, additional/larger throw rugs, curtains and/or room/wall treatments/panels would far exceed the price of an additional custom third subwoofer.)
After playing with our subwoofers for over a month, in my opinion, the above is as sweet as it's going get..........enters the need for the third sub and a WAF who prefers cordless headphones over a speaker/subwoofer system.
Below is the before (red line) and after (gold line) overlay graph of changes I was able to effect. Note how that null just doesn't want to go away? In my opinion, yes, a huge improvement but without aid of a third subwoofer, due to that null, I'm afraid it's "no cigar" as a reward for all the effort.
(The subs are eighteen year old Klipsch, SW-12 II's that recently have had replacement Dayton driver/radiators installed with poly-fill added to assure dampened interior resonances.)
The point of my above, I don't want anybody to think that I'm being vapid in my request and that I haven't been doing my homework before coming here to ask my question.
