    Hello all,

    I have been here in the shadows reading and learning from all of you; great questions and answers/responses.
    Very informative!!!

    I hope that this is in the right place?

    My fronts and my rears are all the same models, full range speakers rated 20Hz-20KHz 5-350watts each. My receiver is 100watts X 5, with additional sub-out. No center or sub yet.
    My question is with the receiver powering the fronts and rears set to "Large"; am I still missing the "LFE"? If so would it be possible to use the "LFE"-out into another power-amp fed right back into the fronts or the rears?

    The fronts and rears are KLH AV5001

    12" Woofer
    12" Passive radiator
    5" Mid's
    7/8" Liquid-cooled dome
    350W Max Power Handling
    20Hz-20KHz Frequency Response
    3-Way Crossover

    Thank you

    So you're one of them lurkers, huh? Bet you're from California too! Why that explains it!
    now if what you're asking is "if I set my speakers to large, and I don't have a sub (just yet) are my speakers getting the LFE or do I have to play tricks in order to do so?" Just set your speakers to large make sure you tell the receiver you don't have a sub.

    Thank you for the reply
    Would it be beneficial/possible to use another amp fed by the "LFE"-out to add some additional bass to the fronts or rears? I would like to try it out, but I am concerned about the two amps interfering with one-another.
    What is wrong with Cal, other than the smog and crime rates??? We like music and HT just as much as the rest of you [​IMG]

    Don, we'll just keep this in-state, then.

    I'll take a quick run at this. The rcvr's Sub Out outputs a line-level (low voltage) signal containing ALL bass PLUS the LFE track from DVDs. LFE (low frequency effects)is the .1 in DD 5.1

    When using the rcvr's bass management circuitry by selecting SWFR on the rcvr (remote setup), this signal is output at the receiver's built-in crossover point be it 80Hz or 90Hz. All bass under this crossover point is directed outbound --- to a sub -- and it needs a separate amplifier. This is the normal way for 5.1 audio with a sub.

    As Chu says, with your speakers set to LARGE and telling the rcvr NO SWFR, you are getting all the bass and LFE directed to the big spkrs. You aren't missing anything.

    However, with 4 big, identical speakers all set the same, it's like 4 MAINS. Try setting the two rears to SMALL to concentrate your bass punch up front. (I don't know if it makes any difference, but also tell the rcvr "NO" CENTER if you haven't).

    Damned Californians...we got better smog than you do! Good idea by Bill. If you can, and funds permit it, investigate a small sub. The for sale area of htf is pretty active and seems to me that most people are pretty honest about what they're selling.

    Everyone,

    Well in that case I will try the "4 Mains" as Small and investigate a Sub. I do have two 15" in a car-audio box, where they face one-another, "band-pass"? I also have a Sansui G-9000 I am having repaired, 165 Wpc RMS. I could use the 15's in the box as a coffee-table, with a polished slab of granite on top? Would this give me good sound for HT, with the mains set to "Small" or "Large"? For music should I turn the sub off and set the mains to "Large"?

    Cali; All the way baby
    NY; All the way baby

    Thanks
    Don

    PS; who could/should I ask about getting more technical info or even specs/manual on my Sansui G-9000?
