Do you think you need a subwoofer?

Dear pryso: My " ask " to M.Levigne was because ( if I remember ) in their last three speakers in his audio system ( including the today ones ) he owned and own speakers that handle the low bass by self speaker powered woofers ( well I think that with his Kharma's he used the separate Kharma sub's ), so he already has a wide experience on the advantages to reduce the IMD on the speakers and the advantage to have dedicated drivers/amplifiers working in the low bass.

I hope he can read this and want to share his experiences about.

Regards and enjoy the music.

Dear Pryso: I want to add ( a little late!. ) that even if the main speakers cross-over is at 160hz like you say and other benefits that the ones I posted earlier one advantage using separate self powered subs is that that separate subs can more easy be integrated on the room due that you can move it anywhere you need where in a full range speaker you can't because the woofer driver is an integrated part of the speaker and when you move the " whole " speaker to " tame " the bass response you " alter " too the full frequency speaker response .

In other side when you have separate self powered subs ( in true stereo fashion conection. ) using an external electronic crossover always your main amplifier will be liberate it for the low/deep bass response/handling and this means thet that main amplifier will perform better than full range, everything in benefit of an improvement in overall quality audio system performance.

Pryso from my experiences IMHO it is very very hard to beat a satelite/subs main system ( I support/recomended this kind of approach. ) against a non powered/passive non-separate full range speaker and even a self powered non-separate system.

One of the things the speaker SYSTEM needs to do is cover the low frequencies to the same suitable extent as the other frequencies. That requires a suitable combo of amp and speakers. A "sub" in the sense of a separate device that covers the low range, may or may not be needed as well.

That pretty much covers it in a general sense I think. Beyond this, the devil is all in the details!

Dear Mapman: +++++ " One of the things the speaker SYSTEM needs to do is cover the low frequencies to the same suitable extent as the other frequencies. " +++++

certainly that is a " must " to have. Not an easy task but the effort to achieve it is worth on its rewards.
The subs integration has to be: seamless.

Rauliruegas, I would agree except for supertweeters with no frequency response below 15k Hz. There I have found no integation issues. There are two of these that I know of-Muratas and Townshend.
