This replay is way too late, but the Mackies don't have DSP. I got this from contacting there customer service and they also showed me a diagram of the workings of the speaker and it doesn't show any DSP. The JBL 305 also doesn't have DSP. The KALI Audio LP6 has dsp and about 2ms latency according to there customer service. The Mackie is a class A/B powered speaker and it does get hot due to this. I've heard a reviewer remark how the MR624 sounded great at low volumes. While I own the speakers I don't have anything to compare them to, but they do sound good at low volume not sure if it's any better than other speakers though?
Likewise a slightly late response but the LSR 305 and 305P are in fact DSP monitors and make use of the STA350BW for this purpose. System latency is 0.65ms.

So I play a frequencie, then I assume I hook my mic up where I would be sitting if listening to my speakers record the audio and adjust eq till it matches the correct frequencie? I'm not entirely sure what do with the online tone generator?

The 305p contains all analog circuitry, and only has analog inputs. Unfortunately I don't have a latency spec, but it would be undetectable to human ears if there was any latency at all, and measured in nanoseconds.

Hope this helps,

From customer support in emails.. For some reason their customer support is through Harman professional solutions.

PCBs don't lie but customer support might.

No. If you want to EQ out room modes by ear, you would use a tone generator like that website, then sweep bass frequencies and listen for room modes.

If you have a measurement mic, then you would use REW to properly measure the in-room response of your speakers.
Use the Moving Microphone Method for this, not sweeps.

^ Sweep bass frequencies [ this would be playing bass frequencies?] Then I would listen for " Room Modes" [ sound reflections} and adjust the eq till the room modes are fixed?

Correct. Strong modes will be audible as significant peaks or dips in volume as you sweep the band. Unless you have a great deal of headroom available or specific knowledge of the desired listening SPLs, only peaks should be corrected in this manner.

Interesting I can see the chip your talking about. How about the Mackie MR 524 any DSP on there? They even linked me to a diagram of the workings of the monitor and it showed no dsp
The 524 is a simple active crossover and a pair of class AB amplifiers. Specifically, TDA7294s.

I think I'm just gonna buy this https://www.amazon.com/Behringer-ECM8000-Ultra-Linear-Measurement-Microphone/dp/B000HT4RSA and try and do it right. I can probably use my interface EQ if I do it this way.
If you are interested in purchasing a measurement microphone, then I would recommend a UMIK-1. Regardless of the microphone selected however, the four PEQ filters available on your interface are insufficient to implement a proper correction. You need at least 8-10 filters.
