Do you think you need a subwoofer?

Darkmobius - We should start a support group together! My setup originally had the preamp outputs feeding SET amps, and running full range to the satellite speakers. The sub signal was summed mono, with a 4th order low-pass filter. I heard the satellite and sub signals overlapping too much, so now am using a high-pass filter to the satellites. This definitely cleans up the overlap. In the article Raul posted, the author advocates 1st order filters. I may try this in the future, since with horns we are deep into phase and time alignment issues. But then I'm back to freq overlap issues. So, how to find the proper balance?????

Raul,I do think I'd like to try that second sub,since you say I have "nothing to lose".I've seen my sub on the used market,and can get a second one for about 2500 U.S.dollars.Can you lend me the money,to verify that it will be a big enough improvement?I've done a dumb thing,by promising my family a vacation,this summer!Best regards!

Thanks Raul for posting the exerpts from the review of the Vandersteen 2wq for fellow audiogoners; As you know i,m already getting the 2wq and i hope its somehow a poorman version of the velodyne,s you recomended me. I,m really looking forward to meet you on monday at your place. Regards, Carlos

Dear Scott: Btw, I choose ( too ) 1st order filter for the high-pass on my system. This high-pass filter is inside of my 20.6s. It work for me.

I think there are no rules here other than: test, test and more tests. Now, why don't contact with the designer/builder of your subs/speakers?

The " spot on " integration of the subwoofers is not an easy task, I take more than six months to do it and today ( time to time ) I still do little adjustements.
I know that this hard work sometimes is very frustating but I can asure you that is worthwhile. Good luck!!

Regards and enjoy the music.

yes most people need subwoofer. ironically it should be removed from the system unlees you can truly identify that your source has low frequency information that requires it. your crossover can act as low pass filter. this takes the strain of your main amp and main woofer.it provides an improvement like you will not beleive.
