Such Great help before. Maybe some more help now

Get a good subwoofer. Here’s one with a design philosophy that would align better with your cornwall and not break the bank.

Looks interesting. Not too many reviews on it. Ill see what I can find. The Luxman amp is weird because the voltage it puts out via pre-out is 2.5 volts where most are 4 volts. I had a problem with a KEF and Buchardt Sub being loud enough. I did find out after the fact their are step up amps to raise the voltage a bit to make it viable

I am not suggesting any change, you have a nice system. I used to have Heresy’s and I liked them, but Klipsch and horns offer a certain type of sound. If you are feeling the need for change I would take the time to audition some other brands of speaker. Or attend a show, at your own financial risk. 😀

Hahaha ya, i just wanted to make sure i am doing my system justice with these speakers. They sound really good to me. My experience is rather limited tho. I think the sub idea may be good down the line after i do minor tweaks. Thanks

I have Forte IV , I don't think i would mess with them except for maybe putting DynaMat or something similar on the back of the tweeter and mid horns.....
