Active line level crossover with subwoofer out - HELP


Hi.

Helping my friend with another challenge. 
Looking for a line level crossover. His preamp does not have a subwoofer out.

What he wants to do is have a high pass filter between the preamp and his power amp. This so his Spendor BC1’s are spared anything below 40 or 50hz. And, the crossover needs a low pass filter to spare the subwoofer the high frequencies. 
Thoughts? 
Thanks!

My concern is if the sample rate of this device will nullify the resolution value of my DAC. The miniDSP HD apparently is 32bit & 192k. The new $60 dsp from Parts Express doesn’t say.


Yeah, this is an issue. This is why I run purely digital EQ (roon right now) or only in the subwoofer.

These DSP based EQ systems have to deconstruct the incoming analog signal, do math on it, and then have a DAC to turn those numbers back into voltages. Not really some one who spent a lot of money on a DAC wants to do.

Using a digital only EQ solution, which does the math BEFORE your fancy DAC gets around this, but doesn’t have a solution for your subwoofer. I use

For the OP, who has 2 speakers in two different locations, plus a sub, though, he’s really going to need EQ to match the L and R plus integrate the sub. Having a fancy DAC is the least of his worries.

Of course, other solutions include a digital preamp with built in EQ. :) Anthem makes them as well as integrateds, and built in sub out, with automatic configuration.
Which war ?

fun room, sounds like a music lover

Bluesound DAC or NAD more than adequate 

have fun !!!!
No idea whether either of these will solve the problem but Parasound Halo preamps have sub out with adjustments

Emerald Physics has the BOM

Purely analog crossover, you can add an EQ to the sub after.

He’s got Spendor BC1’s for a reason, for their organic sound when used just simply with source and amp.

Don’t go sterilizing the sound by putting mini dsp and or digital xovers in the signal path, as they have lousy d/a converters in them and if your friend has a good dac that sound will be lost along with the Spendors sound.

Get a pair of these passive HP filters (pick your frequency) on the input of the Spendors amps and use an active subs xovers/plate amp to blend it in to whatever you pick to roll off the Spendors at. Or if the sub doesn’t have an active xover then the use the LP filters on the sub/s amps as well from the same place.
