Klipsch Cornwall IV

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.

I am considering the Cornwall IV but a question regarding price. Are there any experiences in getting a discount from online retailers since there's no local dealer?

I would prefer having the option to return although based on this thread and other research that would be a very low outcome. I see Music Direct and Crutchfield as well known online dealers but not sure of their willingness to discount since they do have to factor in the potential for a return.
