Hi Everyone,

I'm thinking about doing a diy sub for my new ht room. I currently have an SVS PB13 Ultra (which I love, fantastic sub!) but i'm going to be having a AT screen and will probably be building a false wall to house the speakers so I thought I'd look at doing some diy subs for in the bottom of the wall. The dimensions for the room are 4.5mx3.98mx2.4m. (the speakers/projector screen are actually in a recess that is 3.4m across and extends out about 1m)

What im wanting to do is keep how far the false wall comes out to about 500mm-600mm (speakers im looking at are about 350mm deep) but the box can extend the entire width of the false wall. I love my PB13 because it goes loud and low, so that's what I'm aiming for with the diy solution. I'm open to suggestions on drivers/amplification. Budget is about $2000aud but can be extended if need be and obviously, im in Australia, so i assume that will effect what I can source.

Any help will be greatly appriciated.

Matt

Thanks mike!

The bottom of the false wall will be approximately 3.4m x .5m x .8m (LxWxH). This can all be box if need be.

Are those internal measurements?

No, that'd be external sorry.

I wasn't sure what the thickness of the material would be. Would 18mm MDF be ok (been a long time since i've done a diy sub box, that was for a car).

2x18" subs sounds like it would be awesome!

I'm in

Cost is less than expected too, so that'll always win brownie points with the wife

What kind of adjustments will need to be made Mike?

Is there a point where the box could be too big? Is 800L an optimal size?

With regards to the port, it's just a single 25cm diameter port? (obviously front firing as it's going to be in a false wall)

I'm going to try and give sketchup a shot this weekend (if i get time, got a baby coming in 7 weeks and still need to finish the nursery off!) and try to sketch what I'm thinking.
