  1. The benefit of letting the subs do the work is for bass management.  I had RF 7's and set the XO at 80 Hz.  A subwoofer is constructed to have less distortion than a woofer.  A higher XO can help with dynamics and midrange clarity.  Using the lowest XO may make people feel good about their tower speakers but, that is not the point.  If you can't tame the boominess, additional PEQ may be needed.

  2. Thanks, Maynard.  I did not think it would be as easy as just seeing the tubes test strong.  They need to be current matched also.

    Using a Curve tester look like the way to go.  I don't think the guys at our local guitar shops use a Curve tester.

  3. I tried to order a similar quad set a month ago.  I never heard back from the seller or received confirmation of purchase or mailing info.  Today I received a quad set of RCA 6550 in great condition.  I  will have the other two tested and keep for spares since these are hard to find at a reasonable cost.  They are in my Willsenton R8 along with RCA 6SL7 gt and Sylvania 6SN7 tubes.

  4. I received a quad set of RCA 6550 for my Willsenton R8.  Sadly, two of the tubes did not survive the journey. What to do with the 2 good tubes since I need a matching quad set.  The tubes are Philips or Slyvania since RCA did not make any 6550.  

  5. I would experiment with the subwoofers in different parts of the room.  I would still set all speakers to small and use the avr's bass management.  Tell us about the room or post a pic.
