@mtrot thanks for your input. I'm aware they are much larger. I thought I might be able to eliminate the 2 subs, but I'll wait to hear them before getting rid of anything.
Stand mount to floor stand.
I currently have KEF R3s with 2 KEF R400B subs. I'm pretty happy but have been thinking about moving up to a larger full range floor standing speaker. I have an opportunity to try the Sonus Faber Cremona M and get them on the cheap.. I have never heard them. Is this a upward move or a lateral move? My amp is a Yamaha AS2100. I've done some reading, they're pretty efficient and 4ohms, that should be good for my Yamaha. Any input is appreciated.
