    Ok, having had a Servo 15 for a few days now and getting it set up i find that it produces too much very low bass - is there anyway i could reduce this?

    It is fine with stereo music but for movies i have it 9dB higher than for music as i feel that there is not a lot of output near the crossover with my Tannoy R3's which is set at 80Hz.

    I have done a sweep with Avia and the sub drops away between say 60Hz and 40Hz and then becomes very noticeable from 35Hz to 25Hz.

    I do not have a SPL meter so my system is not calibrated exactly which may be causing some problems.

    have you tried different room placements? I have mine between my front speakers about 10" from the wall. Different rooms certainly make a big difference. I took mine down to a friends at the weekend to try it out in his system which is better than mine in terms of amp and main speakers, but we struggled to get a really good sound from the Servo - a lthough we were a bit stuck for placement in the room. It sounded very boomy in certain positions and in the end we turned it down compared to the volume I had it set at home.

    Sounds very much like a room problem. As been suggested, try different placement.

    Also remember that if you use a Radio Shack SPL (recommended buy for any Home theater owner) to measure, set the sub a few db *lower* than the reading as the RS doesn't measure correctly with low freq.

    I am in the process of trying different room positions right now and a SPL Meter is going to be my next purchase.

    I am balancing it with my main speakers by listening to a CD in stereo with speakers set to large and sub off and then repeating this with speakers set to small and sub on with the crossover set to 80Hz.

    By doing this i have it sounding good with music but for DVD i have the sub set 9dB higher which is fine until there is some serious bass and this is when i feel that it is just too much.

    What i need to do is find a position which reduces the very low frequencies slightly while still providing me with good bass.

    I'm curious as to why you're cranking the volume output up by 9dB when you listen to movies!?

    There's always the BFD (Behringer Feedback Destroyer) option - search this forum for a wealth of information on the subject.

    I feel that if i leave my receiver setup for CD with sub at -9dB then there is very little bass. I know that now i have quality bass this is sometimes perceived as less which is due to lack of distortion.

    I haven't had the sub a week yet so i'll give myself time to get used to the new bass i am experiencing.

    I have read about the BFD and may consider buying/borrowing one.
