Using miniDSP with DSP amps?

If I use a miniDSP 2x4 or a Dayton DSP-408 4x8, is there any benefit in having NXx000D/NUx000DSP amps (two or three in total), or would the DSP functions of the amps be redundant to what the miniDSP is capable of doing? These would only be used for subwoofer amplification. Planned sub system consists of two LilWreckers (15" tapped horn enclosures), and up to 12 twelve-inch JBL subs in some as-yet-undecided configuration for front midbass, nearfield, and two B.O.S.S. tactile feedback platforms (one platform for each row of theater seats, probably four to six total drivers).

I think the Behringer DSP is good enough. I sold a minidsp 2x4 to help fund the 6000dsp I bought. The trick to the jbl 12's is to find the right massive low end boost first to get the bottom end close and then you dont use as many bands to dial it all in in the end.

- 6 BA CR6 array center channel, QSC AD-S82 L/R, 4 jbl 8330a surr , 8 jbl 12" subs w/Inuke 6000. JVC rs420, Denon x4000, Sony x800 -

Yes, it would be redundant. The miniDSP software is far superior for signal shaping, especially below 20Hz where the iNuke stops without special filters. I actually run both amps with DSP and a miniDSP, but it is unique for my setup and works well. Save the coin and just go with the non DSP amps when paired with a miniDSP 2x4 HD.

Edit: IMO, one great feature of the iNuke is the dynamic EQ, which is nice for lower volume listening with MA’s or a BOSS setup for added TR. One thing I forgot, the ability to set the power limit in the iNuke DSP is also very nice to not overdrive your equipment.

I can’t comment on the new Dayton DSP, but it does look to be a great alternative to the miniDSP, but the latter is obviously more popular and well tested with plenty of support.

If you haven’t checked out the BEQ thread, it works in tandem with a miniDSP. https://www.avsforum.com/forum/113-s...2995212?page=1

Thank you for the info, @Sekosche. I currently have a non-DSP 6000 running an 18, but I will be buying one or two more amps in the near future. I was already planning on a miniDSP but I was unsure of any added benefit to having the DSP version of the amps as well.


Edit: Also, thank you for the BEQ thread link. It has helped me make up my mind to get the HD version of the miniDSP instead of the regular version. I wonder how the SQ compares to the Dayton 4x8. I know the Dayton's delay is limited to 8 ms, whereas the miniDSP HD goes up to 80 ms. In the size room I have, with potentially two rows of nearfield subs and BOSS platforms (one for each row of seats), 8 ms will not be enough. I should be able to daisy-chain an output back to an input to double that to 16 ms, but it defeats the purpose of having more outputs than the miniDSP.


It looks like the miniDSP HD is the way to go.

You’re welcome. The HD version is strongly recommended now for the longer delays and higher output voltage too versus the regular miniDSP to avoid the chance of clipping; I’ve clipped the output before with a regular miniDSP when driving subs hard and quickly upgraded.

Dive in!

The miniDSP can DSP from 10-20hz, the settings on the inuke stops at 20hz (though, not a brickwall.)
Other than that, there isn't much advantage really...

With the miniDSP you could upgrade to FP or SpeakerPower amplifiers in the future and not have to change or re-do or acquire more hardware to make it happen. That said, there are DSP FP amps too.

Depends on what your budget and goals are...
