THT placement. Just pulled it out of retirement!

[Comatoast]

So I built this thing around 12 years ago. And 2 years ago I put it in storage because I didn't have any space to put it. I just pulled it out of storage last week and have not done any calibration, or room correction and it's still just kind of sitting where my old sub sat ( HSU vtf3 mk5 )

It's a small area.. I remodeled our basement into our bedroom one. Half of it is our bedroom. The other small portion is my " mini man cave " lol..

I've always had this sub corner loaded but I'm just curious as to what happened if I were to fire it directly into the room... It sounds like a simple thing, but it would actually mean cutting open the wall in the theater room and putting the sub behind the wall in an open area .... But it would not be corner loaded, but be firing behind my TV , into the room ..

The mouth would be firing through the wall behind the TV

The enclosure would be right around where the black toolbox is

Comatoast, welcome to the forum!

You could try using the THT outside of the listening room and see/hear how it sounds. Sub frequencies are omni-directional and you might find that it will work plenty well on the other side of a wall.

Thanks buddy! I built this so long ago, I can't even remember the details lol

All that comes to mind, is , don't go over 28 volts?

Or I'm just having a weird vision of what I think I'm supposed to do , or not do lol.

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've just never fired this into an open area. Always been corner loaded..

I don't have any issues with trying things, but would suck to customize the sub into the back area ( furnace area ) then cut open a big hole in the perfectly good wall ( that will be trimmed out , more than likely with an acoustic transparent mesh ) just to have it not perform to its full potential

Yes it would! Can you show us the other end of that room please mate

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 results with the sub mounted in the wall there. Do you have any testing equipment, REW? That can really take a lot of guesswork and subjectiveness out of the process.

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

So I can put the entire closure behind the wall , and just cut open the wall where the mouth of the port will come through

So obviously it won't be corner loaded, just firing into the room

If it was as simple as just moving the sub to different locations, or doing a sub crawl, that would be one thing..

But in order to actually hear how this will sound, I have to cut a hole in the wall.., and a rather large one lol

No rew or umik .... Would be nice, but I don't really benefit from it as I'll more than likely use it once , set it, and forget it..

And the fact I only have a single sub..

I believe Keryn just wants to see the layout of the whole room, to get a better lay of the land.

Ahh gotcha. Here's a vid during the remodel... It's a bedroom/ away from the kids room lol

But shows the layout. The TV is not on the opposite wall. Where the bookshelf speakers are sitting

What I was trying to say, but not very well , was to put the sub in the furnace room to see how it sounds. No hole cutting, or anything. Just place it in the other area and let 'er rip.

Could definitely try it... How have you guys noticed the sound differences from corner loading vs firing it directly into an open area?

[Bill Fitzmaurice]

Firing through the wall is the equivalent of wall loading, which is fine.

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

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?

[Bill Fitzmaurice]

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.
