Hi there…I currently have a Pioneer SX-770 receiver powering Kef K140 2 way speakers. I am planning to get a set of Kef Q4 3 way speakers. Could someone with more knowledge advise if it will be worthwhile changing and if my receiver has enough power for the Q4s? Thanks!!
Both speakers advertise similar sensitivity, so if you're happy with the volume you get out of the amp now, should be fine. I'd expect some bass falloff at higher volumes with either of those speakers, though.
The largest difference will likely come from getting the drivers up off the ground and closer to ear height. High frequency sounds fall off off-axis, so unless you do your listening on the floor, you should expect increased clarity from either the taller Q4s or by putting your current speakers on stands.
Thanks for the advice! I think I’ll get the Q4s as they will be at the perfect listening height.
