Another consideration is impedance curve. Also, you don't want a high-crossover slope to suck up too many WPC of your SET.
Whic speaker sensitivity is better for an SET amp?
I'm considering an SET amp & Tyler Acoustic speaker combo. The amp will be in the 8-20wpc range. I'll probably spend about $1,500 on the SET amp. I'm consider Tyler Acoustic PD10's or PD20's with an SET amp. The PD10's are 97db 8 ohm speakers & the PD20's are 101db 4 ohm speakers. Without naming a specific SET amp, which speaker do you think would be a better match for an SET amp?
