what are the best 4 ohms speakers out??

Interesting approach. There's a lot electrostatics with low impedence, but because it varies with the frequency i don't think a nominal 4 ohm will get you much farther than 6. The difference in loudness probably won't compensate for how much you're gonna piss off your amp.

I am with Ohlala on that one, if you like your current speaker go for a bigger amp. If you do not like your speakers then look for some that are more efficient. A couple of db more efficient will make loads of difference, and won't "piss off your amp" as stated above. Good luck.

you guys are probably right thanks btw i have nht 2.9's, but now now let me pose a new question, what are some really good sounding speakers that are very efficient thanks agian

I am not saying they're the best but PSB speakers are efficient and 4 ohms. Check the website www.psbspeakers.com.
Good luck

Eantala- In response to your last question, checkout Coincident Speaker Technology for high efficiency, great sounding speakers. www.coincidentspeaker.com
They might float your boat!
Goodluck
