IB is great if you can do it.. The other solution is Multiple conventional subs.

Hi,

What is the question ? Dipoles can go very low at modest volumes.

rgds, sreten.

As sreten says, if loud spls aren't a requirement then a decent dipole can get you very low (mine always did). If you are after high SPLs and you must use dipole main panels, then using them down to ~40Hz, with a standard monopole for everything below, is definitely the way to go.

As DougL says though mutiple subs do work extremely well. I've used both dipoles and mutple subs and prefer the latter by far. It looks better, sounds better and can give real output where it counts for movies.

Extreme Volumes are the main problem, ib is for me only solution, whole systen is dipole based, whits is doing 124 db, over 100 hz, is there any solution make normal dipolesubs working enough hard to make such kinds of decibels, this is like overengineering, 110 db would be fine if there is no crack in the voice, but i prefer "little" headroom

It's very very difficult (i ignore, for now, that it is not even that much important) to go below 40Hz even with closed cabinets. I'd hazard a guess that with a dipole arrangement, it would be even more difficult. Maybe if you sit close to the speakers it could be easier?

Hi,

124dB dipole above 100Hz ... !? And a bass system to match .... !?

Yeah right .... What dipole remotely does 124dB above 100Hz ?

rgds, sreten.

It's kind of an easy question. This is what you build, many have already. I think it will go beautiful with dipole:

Build your own 2x12" TH (The Kraken 212 TH)

You are essentially omni-directional as soon as the wavelength is longer than the baffle, and unless your dipole is 30 feet wide, this is a moot point. Just build a nice well behaved sealed sub.

Physics, not just a good idea, it's the law.

Interisting idea, but does bass quality match with pure dipoles, or are you thonkin that the ear sensitivity in those freququnsies solve the broblem?
