May I suggest this as a first listen ?

That little nook you're talking about is just the entry way into the bedroom.. oddly enough, that's where the sub sounds the loudest when I'm walking around the room and I'm sure it's just because I'm in that little cubby. But man if I could get the whole room to sound like that or even the listeni...

Flip the sub over so the mouth is nearer the floor or lay the sub on it's side. If it were me, I'd only cut the hole in the drywall the dimensions of the mouth, leaving any studs in place, case and frame the hole. Maybe stretch some grill cloth over an insert and stick it in the hole to hide any un...

You can test it by aiming the sub mouth at the wall from a foot away. It will give the same in room response as flush mounting in the wall. Once in the wall anything in front of it will have no effect on the sound. Fourteen foot wavelengths go around obstacles. But anything in front of it will prob...

So here's where I'm at... I'd put the sub behind this wall, cut open the Sheetrock where the port mouth is, then seal everything up good.. and to cover the hole, I'd make a frame out of some 1x2 pine , then wrap it in some acoustic speaker fabric to clean it up and cover the hole... Then the TV and ...

In the listening space, place the sub in the location it would be coming through the wall, mouth aimed at the wall, about about a foot away from the wall. If it produces acceptable response throughout the low frequencies at your primary listening position, it's likely to produce very similar result...

Every driver is different. As far as setting it safe, the only way to do that is with a limiter. However, at only 12v the THT is above 120dB, so I wouldn't be concerned. Well since I'm in the same room as the man himself.... Please don't mind the mess, were in the process of new furniture, and stil...

If you have the ability to limit it should be 35v with 28Hz high passing. The limit isn't mentioned in the plans as almost no one other than pros have limiters. So 35 volts is the limit I recall seeing / remembering 28 volts until 22 hz? Is that still valid? Obviously for 90% of music 28hz and abov...

Anything can be bettered, at the cost of size. A no holds barred horn loaded sub flat to 17Hz with 110dB sensitivity is around 250 cubic feet, give or take. My curiosity ran out at 250 cubic feet.. 😂 So as someone who knew this very well in the past, not really paying much attention to the do's and...

Lavoce, eminence, or even the Dayton um15 all seem like more capable drivers, but I also realize there was a reason you recommended the driver I have, 12+ years ago when I built it.. Direct radiator subs use expensive drivers because they have to. Horn subs use inexpensive drivers because they can....

If it ain't broken don't try to fix it. My TT and 75 watt plate amp are 20 years old, and they operate at least 8 hours a day. Ha, point taken!! I just wanted as more curious if over the years a better ( more capable ) driver / amp was available , just to get the most out of the actual enclosure Th...

Also. I have the old Dayton/parts express DVC 15 from , probably 12+ years ago when I built it, and the parts express 240watt amplifier...


Is there any benefit to upgrading either of the two?

I'll probably just cut the hole for the port, seal it off good and trim it out nice... Not hard by any means to do a simple drywall patch if it's no good

Basically what I want to do is put the enclosure behind the wall, but cut a opening in my room where the mouth will fire into, and as long as I seal it off good it should work... I don't have any issues with trying things, but would suck to customize the sub into the back area ( furnace area ) then...

Yes it would! Can you show us the other end of that room please mate I can't put it behind the wall on the other side ( where the couch will be ) as it's the concrete foundation the wall behind the TV is the back room where we have the storage / furnace I believe Keryn just wants to see the layout ...
