Adam,

I've just looked at your profile and can see that you have the SL2s and the N-sub.

This has perplexed me, as the SL2s are stated to go down to 30Hz, which is very deep and is surely towards the limits of human hearing capability.

What does the N-sub add to this if your speakers already deal with the low frequencies?

Kind regards,

Jon

Very interested in the threads linked above, especially the one where you say the NSub is useful for boomy rooms. Could you explain the theory on how this is the case

I had heard that a Sub could adress bass boom by placing it in a bass node point in the room to cancel out the boom. Or can it be used to steeply "roll off" the SL2s below say 50Hz and the Sub take over 40Hz and below to create an artificial "notch filter"?

Thanks

I did have the idea of a 3 way active crossover (which I may investigate later) so as to cut off what went to the SL2s.

However - the beauty of the N-Sub is the ability to adjust cut-off frequency and gain. It just works well with my situation - where plasterboard lining covers ideal thick stone walls. I have several set-ups. One for AV, one purist and one with a bit more beef (and one for N-Sats).
I may play around with more beef for some of those thin-sounding classic CD releases of LPs from my youth.
