Full range/no sub home theater


Are there many people out there that run a home theater system with ALL full range speakers? In other words, no subwoofer. It seems to me, and from my experience, that running such a system would be the way to go. I'm in the planning stages of building a system and I was going to run seperate subs until I heard a system that had no seperate subs at all. every speaker in the room (7.1) was full range with full sub-sonic capability. Obviously, the sound was something that I will NEVER forget. Not wall or window shaking bass but the kind of bass that is so low and so tight it actually hits you and hits you hard. Each speaker had it's own built-in powered sub, of course, but I didn't get a chance to ask the guy how they were wired. The speakers in question were the Klipsch RP-5's I have several questions.
1.Is it possible to wire the speakers full range without using the LFE input and still utilize the built in sub amp?

2. Is the LFE signal from the pre/pro a dedicated signal from the recording or is the signal merely "re-routed" from the main "small" speakers?

3. If the LFE signal is used, does the pre/pro need to be set up to use "small" speakers? Can "large" speakers be specified when running LFE signals?

4. Would there be any benifit to running the speakers as "large" AND using the LFE input?

5. How many times can an LFE signal be split?

6. Is the LFE signal the only thing that will power the built in amp or can the amp be powered if the speakers are wired direct without LFE?
Any help would greatly be appreciated.

Boy, a lot of "ditto's" going on here tonight. This one is no different.

I too run full ranges all the way around. My mains are rated to do down into the mid 20's with a Q of appr .5 or so. That is TIGHT bass. My surrounds will do the same down to 30 Hz or so with the center making it down to about 40 Hz or so. Keep in mind that all of the speakers in this system are sealed acoustic suspension designs. This means no ports, passive radiators, slot loading, etc.. to help fill out the bottom end. Without those, you strictly have to rely on surface area and excursion to do the job.

Until a recent change in my electronics, i was never getting as much bottom end out of the mains that i thought i should. As such, the subs definetly helped out. As i have not run the entire system in its' new configuration as of yet, i'm wondering if i'll still need the subs. I'll find out soon enough. Right now, i'm simply overjoyed with its' two channel performance and am almost afraid to tinker with it anymore.

I would also agree that this would be VERY speaker and room dependent. While some speakers are rated to go low, the QUALITY of bass is just not there. This is especially true at high volume levels. Keeping the mains "clean" while using the subs strictly for "sub-atomic shaking" might be worth the trouble and space. Like anything else, the best way to find out is first-hand. Try it and see. Sean
