Doug; 

The woofer response was “ ouch” 
lol
bigger the better

I have efficient speakers, 100-104dB.  Not sure.  It can become an issue if, between amplifier and preamplifier, you have too much gain. 

There has been a small revival in higher efficiency speakers and lower-powered amps, but, it remains a boutique community

~~~~~~~~~~~~~~~~~~~
Guess what?
I just brought both low and high db efficiency together. 
~~How is that even remotely possible??~~ 
You ask.
Well I got to thinkin. 
I have so much cash invested in the Thors,,pondering while listening to the Single 8 wide band 94db, + Vifa tweet,,and started making some possibilites in my mind,,what if,,hummm as i stared at the Thors collecting dust in the corner,,what if,,,so I disconnected the Vifa from 1 pair of speaker cabels,,,,,and yep hooked up only the dual 6.5 bass section of the Thors, + the other speaker cabel going to the FR8. 
BINGO!
Now i am a  very  happer camper.
Thought a  bit more,,and I figured there is yet another FR 6.5 m that will outperform the FR8.
Not going to make a  new face panel on the Thors to add the FR 6.5, instead wlll just do what i am doing right now, the 12x12x12 cabinet housing the FR8,  sits right next to Thors, and sounds absoluetly seamless and just drop dead gorgeous.
Dual 6.5's blow any 8,10,12 single bass away at least in the 50hz-100hz. 
I'm not so sure the Excel 6.5 goes below 50hz,..lets ck...be right back....
says 40hz, but i bet its more like 50hz at 80db. 
Still thats a  very nice full 50hz  fora  cello section, timpini, or jazz drum set. 

So now i can salvage some of the Seas Thor,,which I was not prepared to toss away  for a  few $'s on ebay. + The huge Mundorf 8.2 silver gold cap on the W18 xover. + a massive Gertz copper foil coil.
And btw, there is no dome, midarange in the world that will voice mids likea  FR, none, The Millenial Excel tweet is absolute trash, garbage vs a FR 6.5 in the mids. 

So finally its all comming together.
WE just had to use our imaginative powers.
If we all work together as a team, we can bring our systems up to The New 21st C High Fidelity.
6.5 will order when i get some paypal debt down. The mods in my system past year has run into the $$$$$.
madea  few mistakes like Vishay Zfoil Resistors , cost me $550 + $150 labor = $700, Vishay zfoils are for the Hubble Space tele and other  orbital satellites. Not for amplifiers as some might recommend. 
Takman Metal Rey's are the finest.
