SET for 88 dB 4 ohm loadspeaker

I use a 12 wpc SE tube amp to drive 88db/mtr efficiency speakers and can achieve quite high volume levels.

Hi Pawlowski

My speakers respond well down to the 30’s (I believe the specs are –3db at 34Hz ) and the amp does provide a very deep and controlled bass. I have measured response down to the low 20’s, although that must be down 10-20db at those low frequencies.

The most critical thing for a tube amp is a speaker with benign impedance curve. Given that, you’ll be surprised how little in power is needed to provide high(ish?) volume levels.

I think 88db is a bit low for a 300B based set, but I am sure an 6C33, 805 or 845 based set will do well. I have a 22wpc 6C33 SET and it will blast my walls down if I turn it too high.
