Hi Dean,
How big is your room? I remember those speakers because they had them in a auditorium at my college back in the 80's. You've got five of the 4435's in one room? Good Lord! Aren't two enough?
Why don't you first tell us:
1. how big your room is.
2. what type of music you listen to(and/or movies),
3. how loud you like to listen to things
4. how much you'd like to spend
5. what the rest of your system is made up of
The stated overall sensitivity(woofers & tweeter) is 98dB/8ohm. So, unless you are intrested in bi-amping with one amp for tweeters and another on the woofers, that's the number you should work with.
The JBL spec sheet can be found here:

My speakers are rated at 97dB & 98dB. I've got 7 watt per channel single-ended-triode Welborne DRD 300B monoblock amps in a 16'x20'x8' room and I can go pretty damn loud. Not rock concert levels, but enough so that the people in the house next door know what I'm listening to.
The most important aspect with speakers that efficient is that your tube amps be ULTRA quiet. Any hiss or hum will be clearly audible and annoying.
But, give us some info on your system, personal tastes, and budget - and I am sure we can find quite a few perfect choices for your needs.
