Do you think you need a subwoofer?


Why almost any one needs subwoofers in their audio systems?

I talk with my audio friends about and each one give me different answers, from: I don't need it, to : I love that.

Some of you use subwoofers and many do in the speakers forum and everywhere.

The question is: why we need subwoofers ? or don't?

My experience tell me that this subwoofers subject is a critical point in the music/sound reproduction in home audio systems.

What do you think?

Hello Raul and others,

I understand that you advocate using stereo subs.

My question is this: Can you provide detailed instructions on how to hook up two subs in stereo?

For low level hookup - Do you send only 1 channel RCA cable to each sub?

Can you run REL subs with speakon connectors in stereo?
Dear friends: This is something that could help you to integrate the subs to your main speakers:

- first you have to find the best place for your main speakers.

- you can do that with the whole system " on ": speakers/electronic crossover/subs. Then choose the crossover point: 80Hz ( it is a good point to start ) and turn " off " the subs volume/gain and listen to your main speakers that now are working from 80Hz and up.

- listen and listen and listen through your main speakers and move them ( if neccesary ) till you find the best mid/high frecuency response performance.

- then do the same with your subs: alone ( main speakers off ) till you find the best room interaction with.

- now, with the whole system " on " : listen and listen and listen till you identified problems with the seamless integration of the main speakers/subs, that is the target.

- here you have to " play " with small changes in: crossover frecuency, phase, volumen/gain, room treatment and very small changes in the site of the subs/main speakers, till you " done ".

This is only a way to do it and give me the best results to integrate subs, not only in my system but on severals others systems. Sure you can do it in a scientific way. There are no absolute rules here, the only one is: " test and error ".

Regards and enjoy the music.

Hey - Goatwuss - The best way with stereo subs is an extra set of outputs on the preamp via RCA - usually I set the volume on the sub to a certain level (using it as gain) then the preamp can be used as a master volume control. And then ditto Raul's set-up instructions.
Dear Goatwuss: From your preamp: left output to your left side sub and right output to your right side sub .

About your REL question: my english is really bad and I can't understand what you mean.

Regards and enjoy the music.

Dear Biomimetic: About your superteeters question: no, it is not tiring. I think that, like the subwoofers, in many audio systems the integration of STs is a must to have too.

Regards and enjoy the music.
