Vandersteen 2WQ Subs and ARC Power amp
Thanks for the advice on the spikes.  I will install them after I experiment with optimal placement.  I do have some shoes for the floor.  Nice looking systems at Poverty Bay, BTW.  What are the amps in the main system?

I went through the voltmeter based calibration that audioconnection suggested, (thank you) it was spot on with the new crossovers set at 100K.  Man, the system sounds good now.  I have the subs on a wood floor, without the spikes.  Should the spik...

Got my crossovers today, set them to 100K as a start, Q is at 2.  Still evaluating, but all I can say right now is the Rockports are really singing.

After another few days of listening, I am on board with these.  The system just sounds better, some voodoo stuff working here.  Mids are clearer, imaging much sharper, and when there is bass content, it's there, although understated.  Much differe...

Mr V, BTW, was very skeptical about using the subs without the crossovers.  I did that only at low levels to verify that the subs were working.

I did exchange emails with Mr. V yesterday, and along with John R of audio connection the suggestion is to purchase some X5 crossovers so I can adjust the impedance matching and dial in the bass using the procedure that John outlines above (thanks...

This is a long story, so bear with me.  The subs came with WX-2 variable crossovers, with batteries and switches as you suggest.  But, they were single-ended with RCA plugs.  That is a non-starter with my REF 150, which is balanced input only.  So...

The crossovers are X-2B, fixed values no batteries.

Another piece of info, there seems to be little difference in output level with or without the crossovers.

I do hear a thump.  And if I disconnect the main speakers and just listen to the subs, I do have very low level output.  This is beyond subtle though, all the way to nearly dead.  Unless I just need to get used to these....

Pass labs xa25 amp and BW 804 d3?
I use Rockport Mira's, with similar sensitivity to the B&W's, could I conclude that the consensus here is the XA25 might be a good fit for these as well? 
ARC REF 150 Buzzing noise
Update on the sad story of my Reference 150.  Took it to Audio Tube Supplies in Denver, they determined that one of the input tubes was out of spec, causing one of the KT150 tubes to become over-biased and over heat.  This in turn (educated guess)... 
ARC REF 150 Buzzing noise
Called Evan at Audio Research, seemed very knowledgeable.  He thought the problem was a transformer, the good news is there is a service center near me that can repair it.  I think my cost will be about $ 800 including labor if it turns out to be ... 
ARC REF 150 Buzzing noise
Update after last post, there is no time dependency.  No matter when I turn on the unit, it will start to buzz after about an hour.  Anyone know what those transformers cost?
