When you mix and match speakers you create many problems. Maybe you are not a critical listener , if so then it doesn't matter , if you are then don't match JBL's with a
speaker that maybe very different.

The speakers Klipsch put in their cabinets were generally of lower quality than the speakers used by JBL.
A 1974 Consumers Digest test report of the JBL 100 Century reported " The bass ends and starts fading around 70Hz. Which contributes to a pronounced edgy brightness of the sound.
Indeed this brighness became downright hardness on much material, Coloration of sound is well above average "
Your speaker are very efficent. Using a 12 inch woofer , 5 inch cone midrange and a one and a half inch tweeter. Rock music fans love them because of the great presence.

These speakers have a personality , you might like the sound. I use JBL's but they are much larger. I would never use a subwoofer made by another manufacture.


Melvin he was asking for advice on how to hook up what he already owns and not your views on the different products. Many use subs of different manufacture than their main speakers. Some companies such as REL specialize in subs.

mbeigh feel free to use the Klipsch to fill in with some bass. I would set the crossover frequency around 40hz which is the lowest and then increase it if there seems to be a gap in response. I would set the phase switch to the setting that gives you the better bass.
