    have a home cinema setup, with a dvd player and amp that perform brilliantly with music, i have a paradigm pdr10 sub hooked up using a subwoofer phono cable, which i use along with my mordaunt short 902 speakers

    http://www.mordaunt-short.co.uk/products/902.html

    My questions are: should i use my sub when listening to music ?

    If i were to use an attenuated phono interconnect between my dvd player and amp (phono lead reduces output by 14db) would i find that the sub is 14 db's too loud ?

    thanks

    1) Only if it sounds better.

    2) No.

    thanks noodle, short an sweet !

    It does sound better because of the extra bass down to 27hz.

    As for the attenuated interconnect, you say the sub wont be 14 db too loud, care to explain why ?

    thanks

    Because you are listening to the music via a pair of stereo interconnects, why would the sub bass in the signal be 14dB louder than everything else?

    P.S. Why are you using an attenuated phono interconnect?

    To use a sub for music is IMHO necessary if you fronts can't cope, typically when you use satellite speakers all around or you want to fill in the really low end. That said it may also be necessary if your room acoustics obstruct you somewhat.
    After I moved a few years back I notice a significant drop in the bass (of my fronts). I didn't really mind since I usually play music in the background only but once in a while I would "go crazy" and throw in something more demanding, requiring me to activate my subwoofer. Without it would sound really poor actually.

    So it can be necessary but sometimes it's also just a question of personal preference.
    Like Noodle said in his answer to question 1 ... :)

    thanks for the reply Reiner, but what exactly do you mean by 'To use a sub for music is IMHO necessary if you fronts can't cope ' ?

    My frounts response is from 55-22 khz, if i use my sub woofer as well it makes it 27-22khz.
    Am i right in thinking if i use just my speakers alone i am missing out on some of the music ? i.e. only getting 55-22 khz ?

    Thanks

    Subwoofer will reproduce (as an example) 18hz- 120hz, NOT 22 KHZ! :)

    Dial the sub upto ~55hz. My standmounts go down to 55hz, in a small room a subwoofer is not required, however in a bigger room I would use my sub for music.

    If they are not able to handle the lower bass. A lot of (front) speakers are quoted at e.g. 20Hz-20kHz but you will hardly find any speaker that can really go so low. Sometimes, depending on the speaker, it may help to cut of the bass at e.g. 75Hz to improve overall performance. The sub will then fill in the low end (e.g. 20-75Hz) and take care of the LFE (20-120Hz).

    55Hz at how many db? The response should be quoted at +/-3dB or less, else they are meaningless.
    So take this kind of specifications with a pinch of salt.

    Yes, the low end will be missing.

    I recommend you set the x-over at the sub to MAX and then play with the settings of the AV receiver, i.e. set (front) speakers to small and change the x-over frequency (if possible), start around 60Hz and increase in whatever steps - and see what sounds best.
