HI Guys,
I'm totally new for Diy speakers.
I have Sony STRDH720 AVR and I need to build speakers to use 2 channel only for small party. I'm confused between 85W and 105W to use.
Here is the specification of my AMP.

(8Ohms 1kHz) THD : 1%
(8Ohms 20-20kHz) THD : 0.09%
8Ohms 1kHz : 105W + 105W
8Ohms 20-20kHz : 85W + 85W
Output Power (JEITA 10%)/ Rated Output Power(0.09% 20Hz-20kHz 4Ohm) : 10%
Output Power (JEITA 10%)/Rated Output Power(0.09% 20Hz-20kHz 8Ohm) : 140W
Total : 945W (135W/ch x 7 (8?, 1kHz, 0.05% THD))

That's the more conservative rating. Don't let the amp specs determine what speaker to build. Pick a speaker design that works for your room first.

For a modest receiver like that, Overnight Sensations might be a good match.
