Apologies to Norah Jones, I needed more bass!

@erik_squires - all good ; ) - have a lovely years end ahead : )

I agree with you that extended bass is very important. Until you have it, you may not realize it. How much power are you using? Do you bi-amp? Sorry for all the questions. This is a hot topic for me. I love the bass that I get from my old speakers that use 4/12's and lots of power. 

@billpete - Sometimes I tri-amp, sometimes I quad-amp.  

My L/R use 100/250/250 Watts respectively for tweeter, mids and bass. 

My center uses 100/125/125 AND is crossed to a 15" subwoofer with about 1,500 W at 60 Hz, so technically quad amplified. :)

Interesting. Makes a big difference having enough power. I've been a big advocate of that for a very long time. I've never had the efficient low wattage gear so have always gone for big power.

The speakers that I've been using for the last 23 years or so, are quite power hungry and per the manual, are OK with up to 400 watts at 4 ohm X 4. I feed them with 385 x 4. The difference in going from one amp to two is enormous. I found them to be slow and flabby with only one amp and they did not come to life until I had them bi-amped. 

I'd love to hear the super efficient type sometime but I may never have that opportunity. 

@billpete  - In this particular case I tried to balance sensitivity and power.  With dual woofers in parallel I get 90 dB sensitivity (for 2 watts), and a maximum output around 110 dB/1m with a little wattage left over.
