My current project is not nearly completed but like most of us the brain is partially on the next one.
I will be needing a subwoofer. surprise
I am having thoughts of building a coffee table with an open baffle sub as per the pathetic attached pic. I am thinking of a few advantages:
1) I will get a new coffee table for my coffee
2) As per the usual coffee table sub setup, it won't intrude in on the room.
3) The isolating baffles will be quite large, allowing for good bass.
4) ?
4) I will get a new coffee table for my coffee
shoot it down please.

If you could place say a single woofer on an end and use a larger U baffle would that not allow you to use less equalization due to a larger baffle length?
Yup, I think so. I think the baffle size gets really large to prevent cancellation of the lower freqs. It might be diminishing returns?? Large power,to compensate for the roll-off due to a smallish baffle, is pretty cheap. It seems like some sort of eq below Fs is always handy. I'm going to be trying one of these H-Baffle things, I'm really curious now.
You might just use 2 15" or larger, each in a ripole config, and use the resulting ripole boxes as the legs of the table. This way you should (theoretically) get lower response due to the ripole config lowering the drivers' Fs, and the drivers will be completely protected from feet or anything that might go under the table. You will definitely need alot of amp power to get these up to level with your mains/satellites, but another advantage would be that you could run them stereo (I seem to be able to locate the source of bass further down in frequency than is normal, so I like that), or at the very least run the things with a pair of cheaper amp channels instead of needing a more expensive, single monster channel.

Pathetic Drawing???
I think the drawing is definately NOT pathetic.
Much easier to read and understand than the convoluted stuff that usually happens between my ears.
Sorry I can't be any help on how the design should work, which explains why I'm the one asking instead of answering the questions around here.

dunno, ocool
I like the looks of this, would everything be wired in phase?
You'd probably want to cover the top with cork sheets or something that would minimize cups sliding off due to vibrations

Yes, in this configuration I would say they should all be in phase. I have a feeling vibes would be minimal. With the woofs mounted opposite to each other, I think most of the vibe energy would cancel.
hi
or maybe you can forget open baffle bass and do some real bass with this coffee table

ps: been there done that, open baffle bass is not easy, simply put, you need large baffle with woofers with large Xmax on it,
thats all

my personal experience is that where open baffle shines is midrange
I will never put midrange speaker in small box again, its a crime
but the bass..... hmm.... you can struggle here
so my advice with subwoofer is to go ordinary
clossed box, vented box, TL... you name it, all better than dipole bass
