In 2019, I purchased Audiolense XO to try. Long story short, I couldn't get it to work due to an odd error I kept getting. Fast forward to 7 months ago when I interviewed Mitch on my podcast here. The more we talked, the more I wanted to try Audiolense. After the podcast Mitch asked me if I was going to try it and I explained my previous issue. He mentioned to me that anomaly was just solved a month prior.

For the next few months I had to decide on how I wanted to handle the MCH DAC and Roon Core setup. I built a W10 NUCi7 connected directly to a Motu UltraLite Mk5.

@Mitchco charges a modest $500 for the filter creation and also helping you along the way with what issue(s) might come along. For most of us, time is of the essence and a positive result is critical so I thought it would be worth paying the money to have someone hold my hand through the process and hopefully not ruin anything either thus making the $500 minimal. ;)

Mitch might be the most patient man I've ever dealt with on so many levels. He taught me how to count to 8, using 0-7 for routing (you might be surprised how much of a mind boggler this is) among a timing issue during measurement I had. My point is simple, if you're already to this point, just pay the money and make your life a bit easier and know that you have a highly experienced user creating filters for you. The cherry on top is at the end he sends you the file to create your own along with the directions to do so.

If you've made it this far you're asking how does it sound, right? Well, look at the measurements! Translation - Amazing! After about 6 filters I settled on one that I preferred. I can't say enough about Mitch and Bernt of what they have accomplished.

This is not your typical Digital Room Correction (DRC) where phase and timing is NOT corrected. This is SOTA digital crossovers, frequency correction and true time domain correction which now make up my stereo 4 way digital XO system.

Really great and amazing speakers.

The amazing thing is with Audiolense XO I have achieve very similar measurements with DIY DSP active speakers for much much less money

:p

Having had the privilege of hearing your M2 set up beforehand, I had a difficult time believing that amazing experience could be improved upon, so it’s really great to hear this project worked out so well as it was not without a significant time and expense commitment.

The JBL M2s are an outstanding speaker with outstanding off axis response.
Did you choose to apply filters to the full frequency range, limit correction to the model region, or other?
