Do you think you need a subwoofer?

Dear Peepoy2: I think that you own the Trio, right? .
Well, Avantgarde are truly great an very special speaker design. Your model crossover point to the subs module is around 100Hz, I like it.

I think that before you go for the second Velodyne, try to talk with the Avantgarde people because their subs integrated design in the Trio has special characteristics in the crossovers for the subs module can integrate seamless to the horn module.

Now, with the info from Avantgarde you can check if with the Velodyne you can mimic the Avantgarde crossover characteristics and if you can then go for the Velodynes.

Other alternative is that your dealer can borrowed the additional Avantgarde subs modules for you can test in your system.

Regards and enjoy the music.

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

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.
