I heard the top set of speakers at an audio show late last year. They sounded quite nice, but the price was not so nice.

If you want to go OB subwoofer I would be inclined to look at StigErik's setup, I think it makes more sense then those shown.

The top ones are full active and there was fairly complex electronics involved. If memory serves me right the price tag was AU$188k.

Anyone with a keen eye and a big enough photo will be able to identify what drivers they are... the are commonly used on this forum. I use some of the top ones.

Hi,

It works in that it makes noises. Its very poor design though.
Performance vs cost is poor, its brute force over good design.

rgds, sreten.

It makes noise is just about what it would sound like.......You can get a brick to fly, if you have enough power.............same thing here.

Not sure I would be so quick to be cynical, they were actually one of the best sounding speakers at the show... There was only one other set I thought sounded better, so the design can't be that crap. However I will say putting one driver behind the other is not optimal in terms of delay or design, but as I said above the electronics that controlled the speakers was quite impressive.

I was just going to chime in here and say a di-pole subwoofer is an oxymoron, but I liked yours better, lol !!!

seriously though.....of all the "di-pole" subs I have heard, they all make noise and find some sort of room mode somewhere, then, the owner/builder says, : "see, they have bass ! "

I have heard a dipole bass system that did produce some low end.

IIRC, there was a pair of 18" drivers and a 15" driver per side.

I could match it for SPL with a couple of those TB 6.5" mini-subs in a tapped horn each.
