@ozzy62 I've been looking at that amp recently online. Looks very promising! Great to know it works well. Please keep us updated as you get to know it better.

I can throw the O/93 over my shoulder and run them up and down the impedance curve all day.  The CW4 less detailed spec sheet says 8 Ohm compatible. Do they need 20 wpc to get that woofer to dance? 

@wrm57  @bjesien   Yes. You need some power for that speaker and more than just 20 watts (but it has to have clean power; that 1st watt in particular) if you really want to hear what it can do. 


Using a lower power SET on this speaker is a waste of time. While it is pretty efficient, to use a 4-watt SET you'll need efficiency well over 100dB, since with any SET you really don't want to ask more than 20-25% of full power. IME you need at least 60 watts on a speaker like this in most rooms. So 18 watts really won't do it either. Consequently its no surprise that the Plinius did so well, since you'll never get close to running it out of gas. 

Big tubs of flab!

I disagree. I am powering them with 14 watts in my 26 x 15 room with ease. I don’t seem to run out of headroom at any volume level I care to listen. I think it’s more about the quality of the watts and having an amp with some good iron.
