    Have recently purchased on closeout a pair of Infinity 4.1ts for $2K from Audio Advisor. I am experimenting with different setups and wonder if you:

    1) Just split LFE signal and run to sub input on mains.

    or

    2) Run speakers as large with additional sub. (I already had Polk 650)

    or

    3) Use some kind of sub "plus" mode on your receiver or pre/pro

    Maybe there is some other choice I'm missing. Thanks for your help...

    I have Polk RT3000s, a powered tower that goes down deeper than my separate sub (coincidentally, a Polk 650). I use a different approach than the 3 you outlined.

    On my pre/pro, I set sub to "off" and fronts to "large". This sends all LFE to the fronts. I run two sets of speaker wire from the "front" outputs of my amp - one set to my left and right front speaker, and one to the sub. The sub is set to only play signals < 40 hz.

    This approach sounded better to me than splitting the LFE output of my Pre/Pro to my 3 subs (2 towers and 1 freestanding).

    Hope this helps.

    On my A/V receiver, I have three choices:

    1) Mains as small, LFE to sub
    2) Mains as large, LFE to mains (routes LFE from other speakers set as "small" to mains rather than sub)
    3) Mains are large, LFE to "both"

    If you run "both," you can merely set the sub to fill in the frequencies where your mains roll off. If that's 35 Hz, say, a sub Xover setting @ 40 Hz (depending on the crossover slope) might work quite well.

    I run my mains in (large) full range and then phase them in with my sub. I must say it sounds great and was the best for my needs.

    I have mains set to "Large" and subwoofer set to "None".
    The lfe is routed to the subs in each tower via the speaker
    level connection.

    i have my mains set to "small", and have my sub doing all the rest of the work (everything 80hz and below).

    i found that the subs in my towers (def tech bp 2000tl's) would audibly distort when i ran the towers at "large" and tried to listen at anything approaching reference...

    I have a pair of Def Techs BP2000Tl and they are set to *large*. They do handle the .1(LFE) signal as well, I connected them via a y-adapter to the sub out of my pre-amp.
    Bass response is wonderful dynamic and always crystal clear. They never sound boomy or produce audible distortion. Even at the highest spl's at reference level (which can easily be 105+ db's) they always sound extreme natural und clean.


    regards, Holger

    I have a pair of Infinity IL60s that I have set to small. I run outputs to their powered sections from the sub which has a steep high-pass crossover set to 50Hz. So the sub just handles content below 50 and the towers everything above. I tried several other approaches before settling on this one because it eliminated the very low frequencies coming from three different locations and made everything much easier to calibrate.

    I own Mirage OM5's for mains and run them on large. My sub setting is on yes and all LFE is sent to sub. I also have a line level connection to my mains and the sub picks up anything the mains cannot handle. Crossover on line level is set to around 25hz. All other speakers are set to small and the sub handles all bass around 80hz and below for them.
