Active line level crossover with subwoofer out - HELP

DSP makes the miserable space I've been relegated to employ as a 'listening area' (I'd be hard pressed to call it a 'room') tolerable....so my bias is obvious, and enough said.

Exactly.  Sure, we all want to be purists, but the reality is that EQ works.

A light hand, focusing on the most terrible problems in the bass, along with fully thought out speaker integration is a good thing.

perkri, you started another uplifting debate with your simple question :-)

Your friend can also e.g try the blusound node2 streamer/dac which has a sub out before the pre amp. Or the Martin Logan/Paradigm P AMP which I recommend because then you also get the ARC room correction system. The P AMP is fine for driving smaller speakers at normal SPLs. Actually I use it for both Tannoy DC10A and ATC 19 for near-field listening (not exactly small).

To the P AMP you may then connect 28 subs for a really decent bass...

Mostly valuable opinions here.  I, too, am investigating an actual active X-over to take everything below out of the signal to my amp and LRS's and send it to at least @ powered subs.  Those subs can be positioned to reduce nodes.  The miniDSP HD has a x-over, HPF & LPF and by plugging in a PC, Mac or phone app, I believe, 25 bands of parametric EQ.  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. 

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!

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.
