Use Internal Speaker DSP or Buy an External ?

[Richx200]

I have two SVS SB 13 Ultra with internal DSP that need calibration. I just upgraded the subs to the SVS app calibration Amp, so I don't have to adjust the settings at the speaker. The app allows me to adjust Low Pass Filter, Phase, 0–180 degrees in 5 deg increment, Polarity, Parametric EQ 3 individual settings with Bandwidth, Room Gain Compensation, and 4 presets.

Is there any advantage to getting a good external DSP ? (I have a DAC Matrix Elemental I)

Also, I listen to most of my music in Hi Res 192/24 and DSD, will the DSP degrade any resolution if the input to the DSP was PCM analog?

Thank you for your time.

Using an external DSP, one can use more advanced and/or automated EQ like MSO, DL/DLBC/DLART etc, and one can EQ the entire playback system, not just the subs.

Still, proper calibration using just the subs' built-in DSP should give you a significant improvement.

All resolution that's audible to the human ear can be contained in PCM 24bit, 48kHz.

An external DSP may downsample and convert your DSD and Hi Res music, but the resolution will not be affected.

Thank you. I would have to get one with DSD 192/24, I do realize that I don't need it but, I just feel better when listening. I do have a 7.2.4 speakers and would need I think 11 outputs, USB, and eARC/ARC for DTS Master HD and Dolby Atmos.

Also, I looked at some of the units like the MiniDSP HDX HDMI; will it work for DTS Dolby. I think cable box ?

To date, no miniDSP model supports decoding DTS or Dolby, and afaik, no miniDSP model supports more than eight outputs.

If you want to hear DTS/Dolby content through a miniDSP, then you need an external decoder.

Not sure what you think the sub frequencies as to how they may be affected by dsp generally. I'd set up the subs for what they are and possibly not even change anything about 350-500hz

Not sure how the whole room correction process is going to work; I have many options. I have been doing a lot of reading Toole, Everest & Pohlmann, ASR, REW, MSO, and anything else I can get my hands on; I feel like my head is going to explode. Most of the material explains what to do and how the results should look but, they don't explain how to do it or how it should sound when done. The only thing I have gotten right so far is the speaker axis and decoupling the room.

I think I have the subs worked out, and I know I have to be careful handling the issues above transition. So I'm at the point of gathering the means to do the adjustments as per what I'm reading. Using a DSP will give me more tools to adjust above transition but will compromise other areas, i.e. DSD 192/24 DST Master HD, and ATMOS. Also, I haven't been able to figure out how to integrate the DSP into my system. The AVR only allows multi channels through HDMI or USB. All assignable analog inputs are single channel. The DSP outputs look as though they have their own preamp that goes directly to the amplifier so, what is the quality of the DSP and do I eliminate the AVR?
