hmmmm not so bad
a big question---how do the woofer sound--can you compare it to others,,,i have heart--scanspeak (all of them ),,,own Audiotechnology 18H
SB speaker,,,have wavecor balanced ..Vifa
this is to get a idea off the sound from yours woofer
First of all none of those companies made a driver suitable for the line source application. One really had to be designed specifically for that application.
As for the sound of the drivers and my impression compared to those mentioned. I really like the Audio Technology drivers as far as how they are made and the quality control measures that go into them, but have never been a big fan of polymer cones or the sound of the polymer cones. They tend to have a slight characteristic sound of their own.
I have used the Scan Speak Revelator woofers several times. I like how they handle the lower ranges but the heavy moving mass that they each have (even the 5" woofer) really limits their detail levels in the upper ranges. So I have never been a big fan of those either.
The Wavecore drivers are made pretty well, but sensitivity is pretty low. While I have had a bunch of them over here, I have not really gotten beyond measuring and testing them.
The Vifa drivers are a great value, but are not quite to the level of some of the others mentioned.
The purpose built LS woofers have the XBL^ motor allowing them to maintain a linear BL curve much better than the rest. Having an X-Max of 7.8 mm is not bad either. They are a very low impedance so that the over all impedance in the LS-6 and LS-9 application can be an easy impedance load to drive. One uses 2 groups of 4 and one uses 2 groups of 6. They have a low sensitivity too so as to match the output level of the tweeters. They are like a mini sub-woofer with good upper range resolution. They will play to a -3db in the mid to low 20's and the LS-9 is often hitting -3db down points in the teens in some rooms. No other commercial woofer would do that. And the paper cone design offers a very natural mid-range that is as good as any other top level driver. They also have a non-resonant polymer frame that gives them yet one more advantage over the rest.
