Active line level crossover with subwoofer out - HELP

Thank you!!!

So, the MiniDSP looks very interesting!

Looks like it will do exactly what he wants. Read through the manual, and wondering if you might be able to help me understand the sub out portion. His subwoofer, an old Rogers unit, has both left and right channel RCA inputs. Can the unit be configured so a left and right channel can be sent to the subwoofer?

Thanks again!

Good morning all!

Thank you for all the input, thoughts, ideas and popcorn worthy (at times) lively discussion!

Some more info...

My friends place is not set up as a critical listening system/room.

(One speaker is in a bookshelf, the other on a stand further away, the sub is placed in a seemingly good spot, vaulted ceilings, listening area is off to one corner where "desk is and, to make things interesting, there is a large pre war Steinway grand piano in the room...)

This is very much a lifestyle system. That doesn’t mean, however, that the goal isn’t the same as all systems which is do what you can with what you got and try to optimize as best as possible. My goal is to work with what is there, with some hopefully minor changes, in order to have the sound that is flooding the room sound good!

So, because of the shape of the main area and the rather unorthodox set up, bass nodes are not really a big problem. (Walked around the space many times, and there are no "blank" spots or "areas of pain in the bass")

Another bit of info, forgive the pun, there are currently four sources. Turntable, CD to a Dac, Tuner and a Bluetooth device for You Tube/Guest phone stuff...

Many products to research, thank you!

Thanks again all! I suspect, that the RCA Y-Splitter will cause an impedance imbalance, yes? 

And I would need a DIN plug to 2 RCA's - Pre is a Quad 33 :)

I just feel this will cause some more issues.

Hi

No, amp is not a Quad. Spector Acoustics P202

Thanks! This will require some more research! If this works, I could feed the preamp out to a DIY splitter box, and put the high pass line level filter to the amp, and the straight signal to the sub all inside a nice looking box.

Hmmmmm...

Thanks! Sent Quad an email to confirm no issues with running two separate and very different amplifiers from the single preamp out. Really hope this is a viable option!!!

Hi all!

Quick note.

Thanks for all your help.

Built the Xover yesterday - w some cheap caps - and it worked perfectly!  
Bought 4 different values of cheap caps so we could hear how the system sounded in situation. Those can sit in place until the "good ones" are ordered/delivered

 Numbers and specs are great, but, it has to he heard in the environment to really know how its working.

Sub has integrated nicely. Bass is much tighter/faster/resolved. Sound stage is much better - wider/deeper.

For what is essentially a "lifestyle" system, its sounding really good! Think I may be putting similar high pass system in my 2nd system. Small speakers that would hopefully benefit from those low frequencies "mucking up" the works.
