Hi Wayne,What do you think of the bass from Pi Seven Theater Series Cornerhorns with Delta 15 drivers? I realize the drivers are very inexpensive compared to JBL's, so an alarm just went off. I'm putting them together as bass boxes, with 40" front horns with Lowthers (I know, not your cup of tea) for the mids and high frequencies. My preamp and tube amps are pretty high end and getting higher.
I still have time to stop work on them and size them for JBL's if you think the quality of the bass will be that much better.
Regards,
Len
