Two subwoofers.  Yes.

Added another sub I had sitting around not doing anything.  So now I have two 8" subs to accompany my OPOBs.  One sub sounded good, two better.  Much.  I see why Omega recommends two subs.  Happy listening all!

update !

latest layout :  5'  from back wall. 5.5'  speaker separation & 5.5' center line seated position.  Wow !  It's been over a year and I am still awed by these speakers.

Which amp you using? 

I'd go for 6' in the middle.

magnus ma-200.   both my 45 & 2a3 are non-functional

What happened?

[happyrabbit]

The electra fidleity 45 main transformer developed a nasty hum.  I was advised not to use the EML 45's...  But I did.   The tridoe lab 2a3 died during the super bowl.  It died quitely.   it didn't explode and burn down the house so I am happy    I haven't determine the root cause yet.  I am kinda done with tube amplifiers.

Dwight,
Sorry to hear. Don't give up on tubes, however. This must be a bad coincidence. I've been using tube amplifiers for at least 10 years without any major issues. Actually, your 2A3 tube experiences - as chronicled on AC - led me to get an EML 2A3 S for my Bottlehead Stereomour. Great tube.
Good Luck!

Dwight,

I second what borism said about not giving up on tubes.  The Electra Fidelity would be the one I would concentrate on fixing - nice amp.

Although the Triode Lab amps are lovely looking and can be ordered with nice iron, the circuit board mounted tube sockets are a compromise, hence Triode Lab's lower pricing.  Between heat bleeddown from the tube and flexing during tube rolling, the board could be a fail point.  I have no problem with circuit boards as long as the traces are heavy duty and no tubes are mounted on them.

Would I own an amp with tube mounted sockets?  Probably, but I would settle on a tube I liked and not roll, and I would make sure the ambient room temperature didn't exceed 70F.

Rob,

Another option to facilitate tube rolling without wear on the amp is socket savers.  I've had them in the Inspire for some time.  I may wear out the socket savers but, as far as the amp knows, I never swap tubes!
