Hello, I've been using the Kappa 7.1's since 1994 and seriously looking now for a pair of the Kappa 9's if you know anyone who has a pair they would like to release! I'm on here trying to learn more about the pros and cons of the K-9's VS. the K-9.1's myself.
I realize that the K-7.1's are 3 way VS. 5 way on the
K-9's, but listening to the K-7.1's for many years, I was very impressed! Recently I got an older pair of the
RS IIIb's and prefer the overall sound above the K-7.1's.
The main difference is the RS IIIb's are much brighter with more dynamic range, and also have a much tighter bass response. I was looking for something with the brighter sound and I believe this is caused by 2 reasons. 1) the
RS IIIb's have 2-10" woofers VS. 1 in the K-7.1's. 2)The RS IIIb's are totally enclosed with acoustic suspension VS. the bass reflex port in the bottom of the K-7.1.
I'm not totally up on the Kappa 9.1's, but if you listened to them in the same enviorment, (provided they have a passive port) you may find the sound you are looking for!
Still a very wide dynamic range, but maybe more suitable to your listening pleasure! Keep me posted as I need to get past the same learning curve!
Thanks...Bob
