Looking for a smooth sounding 6922 variant
@wharfy Thank you David.  I will check that out!  
Looking for a smooth sounding 6922 variant
I just found 6 Mullard IEC 6922;s made in Blackburn, with codes such as B5I3.  From what I gather, you can't tell the year of manufacture from this code, the second digit is the year and could be 1965 or 1975,  Not gold pins.  Any thoughts?

Hmmm... I might be OK.  Looking through my collection I'm finding those listed below.  It's just that I want to get the most of the system during this test to make the decision about cabling, so I don't want to mess around.... FROM VINTAGE TUBE S...

All the great tube sellers are on vacation this week, believe it or not. A perfect storm! So I probably need an alternative source.  
Best single volume guide to classical music
@8th-note I think you might have found just the right balance.

@fredapplegate Thanks for the suggestion, but not really what I'm looking for.  Want a book about the composers and the compositions rather than the performers. @goethe58 Looks interesting! Perhaps one can find the same referenced pieces on Qobuz... 
Class D Amplifier(s) for SWARM Subwoofer System
I think the drivers are damaged.  I am in touch with @audiokinesis and hope to resolve promptly.

@atmasphere For continuity testing, you are just saying make sure that there is continuity for each of the three pin/socket pairs, correct?  If not, I have a broken cable.  I can test, but I would be surprised to have two broken cables (2 Dayton a...

@audiokinesis Thanks for clearing that up about the Daytons!  I will get back when I set up the CR-1.   
Class D Amplifier(s) for SWARM Subwoofer System
@audiokinesis Hi Duke. I’ll reach out to you offline to discuss troubleshooting on the Daytons. I should have reached out earlier to you about this concern. I am running two balanced outputs from my VAC Signature 2se preamp, one to a pair of VAC P... 
Class D Amplifier(s) for SWARM Subwoofer System
@atmasphere HI Ralph.  I am puzzled too!  I agree that the volume matching SHOULD be a walk in the park.  I am also using Jensen transformers to convert the balanced output from my preamp to the SE input of the Dayton amps. It is the ISO-MAX PC-2X... 
Crown XLS 1502.... real life test.
Wondering how the XLS would work purely as a subwoofer amplifier???  
Class D Amplifier(s) for SWARM Subwoofer System
@atmasphere  Hi Ralph. Good to hear from you. I actually do have two of those Dayton amplifiers that Duke recommends. Each amplifier runs two subwoofers in series, so the effective impedance is 4 ohms. But the output is way too low to balance my 8... 
Class D Amplifier(s) for SWARM Subwoofer System
@bdgregory See the new information above.   So what is so special about these crown amplifiers for running subwoofers? I have only heard a crown integrated amplifier, and I was not impressed. But I am guessing this is a different class. What I ... 
Class D Amplifier(s) for SWARM Subwoofer System
I misrepresented the impedance of the subwoofers. They are each four ohms. So, running them in parallel would present a two ohm load. That will not work. Running them in series presents an eight ohm load.
