1300 cu ft room

well, too much is only too much if you crank it to 11 I have the same sized room, and am using a 15" with PRs and I'm barely giving it a workout (then again, the Tumult is a beast!). I'll soon be getting new subs for a change and will be going with a pair of sealed 15's. If you plan on doing sealed with lots of EQ to get lots of

do they have winisd for mac to model?

Keep the UXL-18's, you won't regret it.

Hey Scotsman


Why are you so set on sealed? Have you considered the Marty cube thread?


Either way I would stick with the 18's


Btw, N. Ayrshire lad here...

So you think 2 UXL-18's will be good for a room that small or overkill as I haven't purchased subs yet, I just picked up an inuke6000dsp.... so.... HAHA

I am set on sealed due to the size of the room and don't want to build large ported boxes. Haven't read anything on the marty cube.


I'm from Angus area originally (Brechin) but live in Houston now.

I hear you, ported usually means a huge cabinet, to the contrary however, the Marty Cube is only 2x2x2... might be worth considering, plus Donny is selling flat packs for it if you are not comfortable building:

I don't think there is such a thing as over kill but at the end of the day an 18" driver is usually not that much more than a 15" so why not just go with 18 to be future proof...you can always start with one, however for HT it's usually best to at least have a pair.


I've been through Brechin, grew up in Irvine but moved to Nashville back in '98.

That sounds good, but with the doorways in the room I wouldn't be able to put the 15's in each corner

How would it model with the 18's in a 4cu ft box?

don't think you have enough subs yet...

That will require a longest room dimension of perhaps 15 feet to provide the necessary cabin gain in the low end.

Model the response of your proposed builds, see what they have for maximum SPL. To account for cabin gain add 9dB per octave below where the longest room dimension is 1/2 wavelength. That will give a conservative estimate that should hold up.

What do you mean by this sir? I have a 1200cuft room.

Room volume is not a primary value of room gain but rather room dimensions as far as I understand. The volume of a room is by-product. There is a lot of information out there which is fairly correct but always missing a key piece of information or is right by bad causation.


So what he is saying, find your longest dimension. Assume 15 feet. The speed of sound is 1115 ft/second. A 15 foot wavelength for sound = 74 Hz. But we are looking for half-length so really a 30 foot wavelength so that is 37Hz. Then take an octave down (e.g. 1/2 the frequency) so divide by two..so at ~19 Hz you should see a 9 dB room gain.
