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?

Dear Todd: +++++ " It appears as though you advocate using a crossover to take the low freq. information away from the main speakers (only have the sub handle low freq, as opposed to running both subs and speakers full range). " +++++

Yes, this is the main idea. You can do this using the internal crossover of the subs and running the signal to your main amplifier from each sub after the signal ( that comes from your preamp ) pass through the sub internal crossover.
You can do it, too, using an external crossover to run the signal to the main amplifiers. The Pass and Bryston crossovers are very good ones for this application.

+++++ " If the main speaker is a monitor that is -3db at 40hz, is it really necessary to use a crossover? " +++++

Yes, absolutely. Please read carefully at: http://forum.audiogon.com/cgi-bin/fr.pl?eanlg&1117893153&openflup&27&4#27

Regards and enjoy the music.

Dear friends: Something that works very well with my Velodyne subs: I mass loaded ( top panel ) with around 25kg.

This can work with your subs. Try it and decide.

What do you use? Is it the same size, smaller, or larger as the top panel? Details please.
Thank you
Thanks Raul,

I must have missed that part of the thread. Thanks! It does make sense.

You say:
"we use subwoofers not only for a better and extended low bass but for a better midrange/midbass too. So, the frecuency crossover will be over that 40Hz"

I am curious to find out what crossover frequency you use and recommend for different types of speakers? ie.
> Large floorstanding speaker -3db at 25hz
> Medium Size monitor speaker -3db at 40hz
> small monitor speaker -3db at 60hz

Just ballparks are fine.

Thanks! and I apologize if there was already iterated on the thread.

Raul,

No need to respond - I read your system notes and I see that you cross over at 80hz.
