Hi,

They are not at all suited for Musical instrument amplification and in normal rooms their omnidirectional bass radiation causes huge problems in the modal range which are difficult and expensive to fix (something they share with virtually all "HiFi" speakers BTW, on both counts), plus they do not really go that low either (eg nothing like the 8Hz from the Bagend Subwoofers)

In todays market PD is too expensive to compete against the far eastern competition and their drivers start showing their age. 15 Years ago that was different.

BTW, I do not want " a massive driver to look at", I want a driver that manages realistic SPL's down into the 32Hz region while operating as Dipole, so that we attain reasonble directivity and compatibility with acoustically small rooms. Of course, I could get 32 - 64 8" HiFi drivers to get a similar displacement and SPL capacity as a good 21" or 24" Pro Audio Sub Driver, but quite frankly this would strike me as silly.

Ciao T
