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.

Hi guys,the 10b-sub X-over is for the sub-main separation.
And no,I'm not using bass management as I'm telling my pre that I don't have a sub(but I do)so with my speakers set to large ,all my lowend is going to my mains and the 10B controling what I give the sub.I'd never take out the passive X-overs in the Revels.I'd go with active speakers before I'd do that.I'll definately check that route out later as more cash comes in.
As to why I'm trying out a external X-over,to see if I get more improvement.I'm sure the Bryston X-over is superior to the Velodyne,Don't get me wrong I like what the Velodyne is doing but if I can get more QUALITY(hopefully)great,if not then I'll know and I'll sell the 10B.
Bob,do you think if the 10B is dialed in proper that I should get improvement,thanks for the replies back guys,
This his been nagging me for quite awhile.
Yes but you haven't said why you are not simply using the bass management in your prepro. Also, can we assume you are using the EQ in the Velodyne?

Yes I am(as little as possible,using the EQ,I'm hoping the 10B X-over is superior to my prepro also.
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. Another way, say if I was using lampcord for speaker wires instead of Cardas GRCS
Quality piece, hopefully gives you quality sound
which depending on all my other sources.I'll know soon enough.
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...

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.)
