What Dirac do to the sub(LFE) is just simply flatten the curve, the test volume is not loud, so it might seam look flat in low volume, but with the volume raise it could be disaster.

For multi subs,dirac process all subs as one.

I integrated a swarm of subs (4x SVS SB13 Ultras) with my Giya G1's before I upgraded to the G1 spirits. It was more to smooth the room response than for added bass.

If you only want to correct/integrate subs or low bass under 200Hz, then a simple processor like the $499 4x10HD (which is what I used) or the $200 2x4HD will work ... you really don't need fancy/expensive processors, 10 bands of parametric EQ/crossover/delay/polarity/level will do as bass correction is minimum phase. You only need IIR filters... not FIR.

I can just tell you one thing, that NONE of the DRC systems are the silver bullet... they will not make a rubbish room sound great ... you have to apply physical treatment and only when that avenue is exhausted .. .then use DRC to clean it all up...

I agree too, I already have room treatments in place, although this room will never be ideal. Main problem area is in the bass and with low frequency issues needing such large traps where big peaks and nulls occur, there is only a certain level of bass trapping which will ever be domestically acceptable/practical. MRC would be ideal, but for whatever reason Meridian aren't inclined to introduce this on 2-channel endpoints.

Having seen the cost of the Trinnov units, I think it would make sense for me to try a more cost effective setup for the H/T correction right now and use one of the other solutions over Roon for the audio only correction (which preserves EBA and hopefully soon MQA). If I'm going to invest that much, I might as well hold off and see when Meridian release an 861v9 so that a more expensive the solution is fully integrated with everything and fully compatible with DSPs, MQA, EBA, etc...

Rodney, would EQ-ing only subs be possible in a modern DSP setup, including EBA (which I find very beneficial) or is this a dead-end?

Even for subs I think it worth the money much much better than DIRAC.I also bought a 88D with Dirac,i put it between Vanity HD and 861, I feel sound was coloured a little bit,not so sure about that because I sold it immediately due to poor support for multi subs.
Thanks, interesting, so little information out there about the X4.

I guess it would work well for subs only in a legacy setup without EBA, do you think it helps?

Hi Chris, back to the nanoDIGI...

I have a Samsung TV with toslink out, my only source (and maybe a MC200). I'd like to connect it to a Meridian 5.1 DSP system: DSP420 LCR, SW5500 sub and DSP33 rears. Can I get id of the 568mm.2 and use the nanoDIGI intead? How would the COM work with the nanoDIGI?

Thanks

You'd still need the 568.2 to connect and route the various audio streams to all your speakers. The nanodigi doesn't decode DD/DTS, not even prologic.

I see, thank you for the clarification. So it would only add room correction to the 568, right?

Yes, and you'd want to hook it up between the 568 and relevant DSP speakers, rather than source to 568. That will mean disabling MHR if you're using that but I haven't heard any downsides from doing that myself.

Do you have subwoofer in your setup?
