Hi,

Can anyone recommend an external cross-over other than the Bryston 10B for use with 2 active subs?

I've nothing against the Bryston, just looking for possible options.

Thanks.

If you are running your mains full way and just bringing in the subs to augment bass, why not use subamps that have built in low pass filter and room EQ?  I settled on cheap Parts Express amps but Velodyne also have fancy ones.  Kevin at DIY Cable hooked me up.

You can just use Fmod in-line, low pass filters too - dirt cheap at like $30/pr.

I wouldn't use them as hi-pass on your mains but for the sub circuit they work great.

I've heard good things about these as well: http://www.reckhorn.com/index.php?ln=en&prod=b1

I use ACI 65Hz passive high-pass RCA filters on my mains. They work great and keep my mains from attempting to dive too deeply into LFs. They also have an 85Hz and balanced ones as well. Improved clarity and imaging. No adverse effects. Highly recommend using these on your mains if you have active sub(s).

Of course if you want to go the active route, you might want to check out a Behringer DCX2496. A digital crossover that many people love, especially for the money. I think some other people are also using some simpler units from Behringer just for sub work...

even if using active subs, i would still use an outboard active x-over.  part of the benefit of subs is not having to run your mains full-range.  99% of speakers will sound better that way, having been relieved of having to deal w/the lowest frequencies.  yust set the active subs' x-overs at their highest setting, & set the active outboard x-over about an octave lower.  i would recommend the marchand x-overs over the brystons, even if they weren't less expensive.  if you wanna spend more, get the marchand tubed x-over.  or, go dsp w/something like the deqx...

Hey Doug,

Can you explain in real basic terms what you mean by go dsp/deqx?

Thanks,

Monty

DSP = Digital Signal Processing, not just an audio term but can be used in this context to denote crossover functions, EQ'ing, time alignment, etc...all done digitally instead of being strictly analog.

Second that. Try running your sub up tp 65Hz using these. The Harrison labs are a bit bright and nasty . They are inexpensive enough to try. Your gonna like them for the price.

SI 1 SmartSub Integrator from Thiel Audio

"The Integrator's SmartSub microprocessor technology automatically
calculates the subwoofer response that provides the most seamless
and musical system performance based upon main speaker parameters
entered into the Integrator by the end-user." - as from the Thiel Audio site.

Then you have another type as well, it's called:
BSS Audio FDS-366T Omnidrive Compact Plus.

http://www.bssaudio.com/crossovers_loudspeaker.php - this being the product page.
It's just about the most versatile sub integrator I've ever seen.
I will however require a lot of know how or that one REALLY reads
the manual, from the end user..  You have to do that?
Oh yeah, with this one you do..

Which brings us back to the Bryston unit.
It just works! No fuss! Right?

Thanks for the info Imperial - I do like the look of the Omidrive.

Cheers.

Hi,

Can anyone tell me if the BSS Audio will work with either a single mono active sub or two mono two active subs and either a pair of 2 way active PMC AML1 speakers or 3 way Klein & Hummel O300D active studio monitors?

Many thanks,

MontyW

Typical applications:

Stereo 3-way.
Stereo 2-way plus sub from input C.
Triple Bi-amp for stage monitors, with delay and EQ.
Dual tri-amp for stage monitors.
96kHz Studio monitoring systems.
LCR Monitoring systems (post-production).
6-way systems.
4-way plus 2 full range outputs with separate delay and EQ.
6-way Zoning ( full range outputs, giving delays, EQ and limiters on all zones )

---

It appears to be able to sum inputs to give out say one mono sub channels as well.

But for exact stuff on this you could ship of an e-mail to the maker of this gizmo.
