Question Pro Audio Woofers good for Dipoles??

Been looking at Pro Audio woofers as being used in my next project. They seem to actually be good for a dipole configuration. They don't have the strongest cones and spiders, but since there will be no back pressure, I don't have to worry about it flexing stuff. Also the paremeters seem to be in line. I would be looking at the 12"-15" models and they seem to have good Qts's for dipole (most are like 0.6 and up), they can take alot of wattage, plus what seems really important to me is that they are really effecient....many in the 95dB + range, which seems excellent for dipoles....don't have to crank the watts up as much. They also seem to be very well priced. Most run about $40-$50 for descent QSL or Selenium or even some Eminence woofers. And with Sensitivity levels usually about 6db higher than most home audio subs, you don't need nearly as many.

Of course this would not be for mind altering bass, just more like the 50-200Hz range.

These are what I use and they sound excellent! The model # is PPA 15 and ran me 35 bucks each.

However, the cheapest I can find them now is $39 which is still a great price.

Also, if you haven't read it yet, check out my older thread about my venture into dipole subs. I learned alot in that thread!

The problem I see in pro bass elements is that the specified linear xmax can be really small, in some units it may be no more than 2 mm. For a dipole woofer you need to have big volume displacement. And for an enjoyable high quality sound it must produced linearly. It doesn't help much to have a 18" element with large cone area but with tiny linear xmax, if the produced linear SPL (with some specified amount of distortion) is no more than from a 12" hifi element with large linear xmax. The 12" element will fit into a smaller an thereby a more nice-looking baffle than the 18" monster. Take a look at Peerless 12" XLS instead?

The second problem in PA woofers can be turbulent sounds from the pole vent during high cone displacement. The XLS has vented spider and dust cap so the air noise is not an issue.
