I'm a theater organist, and the B&O pentas are pretty satisfying. I used to use Dahlquist DQ10's with DQ 1 Subs, but the Pentas are pretty amazing. As you probably know, I just bought a used reconed Velodyne ULDII 15 sub. Just for more amazing bass if I need it.
I'm sorry, I was going to welcome you earlier and then forgot.
Where and what is your theater organ? I suspect from your Avitar it is a Wurlitzer.
Please tell us more about your interesting career.
I also have vintage tape machines.
I have two Revox A700 half track machines and three Revox A77 machines. Two are high speed 2 track and the other a standard speed 4 track. I also have a Brenell Mk 6 the later version with the parabolic tape path. It records 2 track but is four head and can play back 4 track tapes, as there is a 4 track playback head.
There is Dolby A and B, plus dbx 1 & 2 code/encode available.
I also have an audio workstation with WaveLab 6 that has extensive editing and CD mastering facilities.
So if you have tapes that need digitizing and mastering to CD I can do that for you.
Michael Barone sometimes features theater organs on Pipe Dreams. Have you heard any of these programs?
In my youth I used to listen in the Reginald Dixon's recitals from the Tower Ball Room Blackpool.
My speaker system uses transmission line speakers except for the side surrounds. These are basically highly specialized Gadeckt organ pipes.
Anyhow I hope you stay on this forum. I'm sure you have a lot to teach us.
