active X-over


Hi guys,would anybody know of the effects of connecting a
Active X-over with speakers that have passive X-overs in them already.
My DD-15 subs X-over will be disabled.I will be going from my prepro out to Ext X-over inputs,X-over sub low pass outs to sub input,X-over highpass outs to 7B-sst mono blocks.
my mains are revel(50as) and I assume should be set to large as to send all low end to mains,Thanks for any thoughts.

I think the only way to tell would be to take some measurements. I don't think I tell purely by ear.

Typically the biggest problem in full range free standing speakers is the broad suckout somewhere between 100 and 300 HZ - it can be a real devil of a problem and it is near universal too. In some cases a 12 db crossover on the sub may work better than a 24 db filter typically from a pre. You need to try it and see...but I'd recommend measurements and trying all kinds of positions for your sub too - ultimately positioning may be the most important factor overall...
To me the signal has to go thru the prepros bass management(
or not)or the subs bass maagement.I could be wrong,but if the signal goes thru the 10B,I'm hoping for more quality.To me it's like replacing a average component and upgrading to something of way higher quality and hopefully quality bass while freeing up my mains of lowend.

If you are passing the signals through the pre/pros DSP, it will make little difference to the signal "quality" (whatever that means) if you choose or avoid a simple function like bass management. I do not know what prepro you are using but I can think of many better ways to use the money you are spending on the 10B. (Not that I dislike that device but I would see it as more appropriate in an entirely analog system.)

I have found the best position for the sub using the mike and the display from the DD-15.I put the sub where I sit and with the DD graph on my tv screen I walked around the room to see where I could get the flattest response and that's where the sub went.
I am using a Arcam av-8 prepro and I'm going stereo direct(bypassing all digital)my cdp is a bryston BCD-1,
I'm using the analog outs of the cdp and into the analog in the Av-8,utilizing the dacs in the BCD-1,which I find superb.quality signal to me is,free off as much distortion,noise or what ever else gets in the way.the sound of am radio compared to FM or even sattalite radio.
I got a great deal on the 10b and I'll have her in a few days,as I say we'll see.

Hi Bob,that,s what i'll be doing also is highpassing my 50as.
I just figure that the 10B should be superior to the Av-8s internal X-over+the DDs X-over.I like what I have so far as sound goes,I'm thinking maybe I can squeeze more out of her.
True my Av-8 is not all analog,when I do run her in bypass mode she's very quiet.I just think if the sound is going thru a Quality piece,then I'm hoping my music will benefit.
to me it's about the music,if I can get a smidge more Quality sound using the 10B,great.To me it is worth it to purchase whatever to hearing a nice sounding bass or vocals ect.I even did this on audiocircle,some say why am I doing it this ,just stick to what you haveand some say try it.
I am running as Analog as I can as far as my cdp(analog outs,using the Bcd-1s dacs into analog inputs on the Av-8.
definately not pure analog.Maybe the Bryston SP3 will have a pure analog section,she won't be on market for awhile yet.I could run her thru my PH-stage(Allnic-1200)tubes.
Just looking a little music upgrade that's it,I guess I need a total analog system and a digital system,then I'd need @x the amps,speakers ect,Bob,when I receive the 10B and try it out for a few days and let you know,Don
