MiniDSP Flex: Perfect Sound Through Digital Room Correction? 

A comparison of the ones you tried would be appreciated greatly. 👍🏼🎶😎

A comparison would be helpful for many of us

Welcome to Sprockets! Hey good video.

Wow Michael, super helpful. I got lucky finding your channel last month and am working my way backwards on your content. You are an excellent teacher/instructor/guy with a sense of humor/person with feet on the ground. I say that admiringly, given I am an old fart who has suffered through waaaaay too many bad lectures. lol

Yes comparison please!

Thankyou Sir... 🙏🙏🙏

Hi Michael, I had the same Adam T7V+Sub 10 combo, and was using Sonarworks software for room correction. But everything changed to much better when I purchased Genelec 8341A (and 8330A for surround) with RME interface. Genelec's have built-in DSP and I am powering them over AES via RME Fireface UFX III. I've calibrated them using Gelenec GLM 5 system and for me - Genelecs were the game changer, I have never before heard that depth of field, it's just amazing. Of course, it is a substantial expense - but it is worth it, I am so enjoying them. Cheers!

Was going to buy the IK ARC but I'm glad I waited. Would love a comparison video.

Love my Dirac/MiniDSP combo. My room is very well treated and with my ATC25s I only have a +-2.5db variation with 1/12 smoothing in REW. I really do want to shoot it out with Trinnov Nova though….

RME also includes now room correction in the Totalmix fx with their newer interfaces

Great video, I tried Dirac software today and it's actually not bad at all. It is possible to try it for free for two weeks and it runs without DSP hardware. You can use Dirac Live Processor for applying the filters, the nice thing is it works system wide and you can store up to eight presets. You can use any output device so no hardware necessary. The phase and timing corrections are really great as is the delay compensation for your speakers. I made two measurements, one with a flat target and one with the Harman target. The Harman target is definitely much better for my personal taste. I measured the results separately with REW to measure the actual results, my system is much closer to the Harman target now and sounds so much better, especially the stereo field. Now I will test if my mixes will translate better to other systems, I think it will be much better. Since this doesn't needs extra hardware and works outside the daw, (so it's not possible to accidentally bounce files with room correction on) which is great. I'm definitely going to give this a test run for two weeks. So far I like it 👍🏼

Modern monitors also have room correction builtin. For the price of miniDSP/Dirac you essentially get one monitor for free (Neumann KH120ii are 800€ each, plus 275€ for the MA1). This makes these monitors a good option if you want room correction. Also, as has been mentioned, the RME interfaces with advanced dsp capabilities can be used for room (and headphone) correction. This requires fiddling with REW or similar though.

Awesome video. Could this hypothetically work to tune an analog set up to your room as well? Or does the microphone thru the calibration process need to be done through the same interface as is outputting to the speakers? Also, my speakers (pmc result6) have a perforated grill on the tweater to enhance the sweet spot (very helpful for my less than ideal setup). Do you know if the dsp mini would affect this feature of my speakers? Thanks.

You sound so much like Arnold.

I haven't used this device or Dirac, I'm confident it gives good results. But the IK ARC4 Studio also gives good results, is cheaper, includes the software license, and also has a fully balanced signal path with relay full bypass... testing its results with SoundID reference and REW it gives good correction and is better than ARC3 and Sonarworks or my homegrown REW profiles. Moving speakers will not affect the room modes, it might alter the excitation of them. I am doubtful about the efficacy of DIRAC phase correction above ELF in a non-sealed room that is not an automobile application, will have to try it! Thanks for the review.

Hey. Is it clipping/limiting/volume down signal when for example - I will boost a 40 hz 7db+ ? or its without any distortion?

I too would like some type of speaker tuning solution shootout.

Sensei! Why would i need dirac live while i can do the calibrating myself with the FLEX, a calibration mic and REW?

Hi, thanks for this review. How good its dac preform? Or do you suggest to use it with external dac?

Thank you for the great video. Can you please tell me how much customs and tax were added in your case? I can't find a quote for shipping to Germany. And I am a bit anxious because I once paid the price of a product in customs when I ordered a backpack form the US 😶 Thanks again, Stefan

Hey Michael, I've been waiting for a cheap alternative to Trinnov's solutions for years. My listening space is definitely sub-par. HiFi folks have Dirac functions in their (super expensive) amplifiers and Dirac seems a really well developed system. Thanks very much for posting as i had no idea MiniDSP made these products. So glad i subscribed to your channel a few months ago! 😀
