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 Gmorris: +++++ " . I have been able to obtain seamless integration of the subs with the maggies after many weeks of experimentation and frustration. " +++++

Always is a hard work for the seamless integration of the subwoofers: test and error experimentation.

The Maggies are wonderful main speakers and I never heard along with subwoofers, but I can imagine.

+++++ " To fully recreate the recording space you need the lower octaves even if the recording involves instruments sans the lower registers. " +++++

THis is absolutely true. I agree, too, with any single word about the advantages of two subs instead only one.

Eldartford, I would like your opinion on something because you have had experience with a wide variety of sub types, development, and placement in different systems – not just one or two purchases in their own system. This is in regard to all-in-one designs, like my Vandersteens, where the subs are separately powered, driven, and integrated into the same cabinet as the other drivers. As you know these incorporate a high-pass filter just before the amp inputs and, ultimately, the lower end is passed to the subwoofers and the rest to the three-way drivers (woof, mid, tweets) above. This makes these speakers easier to drive than some, but what do you think about the sonic tradeoffs of such a design? I have had subs previously, but really did not care at all for the extra space required, additional connections, placement concerns, etc., etc. Realizing that there are always trade-offs to be made, I chose practicality (if you can call the cost of these speakers as practical), possibly over function. I will note that the sub section performance of the Vandys was very good, at least to my ears, once the speakers were positioned properly (which took some time). But, after I had the 11 bass band contours adjusted, the lower bass seems to integrate perfectly and seamlessly. Wondering your impressions of such an approach and what one may or may not be sacrificing with these over separates, especially in terms of conveying the information on analog recordings. Not looking for a critique of these particular speakers themselves (there’s plenty of those to be found) but, rather, the approach. Much obliged!
Dear Eldartford: +++++ " I run the SWs up to 200-300Hz, and there is no doubt that it is better. " +++++

I can't imagine this situation ( maybe because I don't have enough experience with the Maggies ). Which are the frecuency limits of your SWs ?

Regards and enjoy the music.

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.
