Full range speaker for rogue 90 or 100 wpc amp.

My favorite kit speakers are from Pi Speakers. I have built the Two tower and the Four. Outstanding value, even pre-built. Can be driven with low powered SET amps, so your Rogue will hardly be breathing hard.

I'm also a big Legacy fan but their entry level Studio HD monitors start at $2065 and don't go as low as you desire. You rarely see current production Legacy speakers for sale; folks tend to buy and keep this brand unless upgrading to another Legacy product.

For a well liked DIY project consider the Solstice from Parts Express. Quality Morel components, transmission line enclosure, not too big for your room.

My 100 watt Rouge Audio Cronus Magnum II has no problem with Ohm Walsh 4s.  They aren’t the most efficient and they go plenty low.  I found a pair used that had the speakers redone.  The pairing seems synergistic.  They seem to be fuller with this amp than the 200 watt solid state amp I previously had.

thanks for the diy suggestions I will check them out. I also checked some out at speaker hardware. the only thing is I don't know if the dayton reference woofers are decent. Any thoughts.
