What subwoofer for baffle/screen wall?

Hi all

Long time since I posted anything on here, but I'm finally in a position - after many years talking about it - to sort out a dedicated room. My new house has a single garage joined onto the house which has already been converted, so it's prime for adaption to a dedicated room.

I plan to create a screen wall and have everything hidden. Mains will be JBL 3677 (in a single garage :laugh: ) ....and the wall will be between 12-15" deep. I plan to construct a timber frame, mount the JBLs off the floor so the sub will sit underneath them. The main restriction will be the depth as I don't want to lose too much of the room. So what are my options?

In my living room I have an Arendal Sub2 which will remain there, but obviously a design like that won't work in the new room...

Thoughts?

Sounds like an Octo coming on:D

I remember Jameskatie doing an array of about 8 drivers in a horizontal row under the screen they sounded pretty phenomenal. I don't think the drivers were more than 10"/12".

I don't know if there is a thread on it somewhere on here.



His avatar shows something like I was thinking about.

This was the thread, you were on it a few posts so you must remember it well.

Is this the sort of thing you would consider?

I know James had some health issues and has not been on here since 2018 I hope he is still around somewhere. 😍

XTZ Cinema 2x12 is low depth made for below the screen/inside baffle wall. 1000w rms amp using IcePower amp modules (PSA uses them too for reason) with PEQ, 2x 12" long stroke drivers, sealed cab. 17-180 Hz (+/- 3dB)

1000 x 450x 300 mm (W x H x D)

You have to ask price from XTZ EU.

Some max output figures taken from Italian forum. I think the 2x12 is also called DS12.17. The D12.17 is dual opposite version with same drivers and amp very similar to your Arendal Sub 2 but slightly larger cab.


D12.17 / DS12.17 SPL test, compared to 3x12 which is one of the most powerful subs on the market (CEA 2010 2M.)

20 Hz 102 dB (3x12, 110 dB)
40 Hz 118 dB (3x12, 121 dB)
80 Hz 119 dB (3x12, 121 dB)
100 Hz 120 dB (3x12, 119 dB)

Are you using any other subs elsewhere?

I’ve got a pair of Arendal 1s behind my screen (and a pair of 2s in the back corners). They help with my overall response, but taken by themselves they have a huge dip from 40-80hz, so would be no good by themselves.

Just something to consider.

Have you considered an Infinite Baffle sub? The manifold for the sub could be built inside the room or you could use the adjacent room or loft space if you have a pitched roof.

If you want to go with a conventional in-wall type of sub I'd perhaps consider a floating design similar to what JL audio use.

Hi, an infinite baffle design won’t work unfortunately - and I don’t want to go down the in-wall route really. Will look into that though.

almost wondering if a couple of svs cylinders lying down would work….

Hmm can't see any reason why cylinders couldn't work. The only thing to think about is if the ports are on top and open, and you have them lying down, you probably wouldn't want them too close to each other as there could be cancellation issues.
