Shallow Cabinet Sub

[MuaDibb]

I'm looking for a cabinet design that is not very deep and is a folded horn design that discharges out the side. Any ideas or plans someone can post? Please?

What frequency do you aim for and with what kinda driver?

I would like to get 30Hz, driver isn't so important. I would like something shaped like the Cain & Cain Bailey, wide, flat and not too tall. I might use two so maybe I could use smaller driver. It doesn't matter if its ported, sealed or a horn type but the form is very important. Wide, flat and not too tall.

If you would make a bass horn capable of 30 Hz it would be really large, even in optimum enviremont (corner loaded, etc.)

Looking at the Bailey it looks like an basreflex and you can form the HxWxD of a basreflex pretty much to whatever your needs or desires are. Something similar or the same in shape as the Bailey wouldn't be a problem.

What driver to use in that case isn't in my field, so I'll have to leave it to someone else. Good luck!

Yes you can get a small enclosure you play 30Hz, it just may not be that loud is all, how many woofers can you have and what type of amplifier do you have? it must be stable if driving more than say 2 four ohm woofers.

Why is the shape important? a coffee table?

If you'll consider ported instead of a horn, you might get some ideas from one I built a while back:

Thanks for the replies. Nice sub Collo, I was lloking for something with a thin profile and yours looks nice, I may try to build it. The only thing missing was dimensions for the cabinet, or at least I didn't see any. Could you please post, and the port sizes and lenghts if they are not on the site I will look again. Thanks Tom

How about laying this on its side?:

Hi there Mau'Dibb

the external dimensions in mm are:

1130H * 200D * 590W , which for 18mm MDF walls (double front) gives a working volume of 78 litres.
A pair of ports, 86mm internal diameter, 460mm long give a tuning frequency of 29hz.

The box volume and tuning frequency are going to depend on the driver you choose, so this design is more of a guide than anything. Once you have chosen a driver, I can help you work out the box if you need.

ps: It sure is hot here in Aussie at the moment - I could use one of those still suits....
