Chris ordered a pair of BePure 2's with custom side-firing passive radiators to use as a second check on music he was mastering. He recently sent me an email commenting on the results. Here is his email...
"Hey Jim,
This is Chris Capaletti, I am sorry it took me so long to reach out regarding these speakers you made for me. I was waiting on a custom amplifier that took about an extra month to arrive. That was the most trying month of my life, staring at these beautiful speakers without being able to listen to them.
Though the focus of this email is my listening & measurement impressions, these came out absolutely beautiful and match the acoustic treatment I have in the room perfectly! I am not planning to say much regarding the sound / measurement of these in this email but I do feel like what I am seeing / hearing warrants a conversation with you. It is truly AMAZING!!!
I am flat down to 17hz with no enhancement and only using dirac to flatten out the humps of my room. Yes, what I am saying is only reduction not elevation!!
I am a systems calibration engineer for a living and also a mastering engineer, and the sound that this passive radiator version of these speakers is producing is unimaginably good. I am driving them with a custom built amp, based on the latest iteration of Bruno Putzeys Class D module, that after much research made me feel was the perfect companion for your speakers.
Maybe the ported version sounds the same / better, but considering all of the systems I have heard / tuned in my career I feel like I can honestly say this is something very special. I honestly don't believe a ported system could keep up with the speed at which this system fires bass. Not even just bass but it has a percussive nature all the way up through the mid band.
My original plan was to have this be a second take on my mastering work that I do on my Amphion system in the studio, but after playing things back on both systems I am having a VERY hard time convincing myself that I hear better on the Amphions. Anyways, I feel like in the least I owe you a positive review somewhere that will help you out, but I didn't know what your plans were for a radiator version of this speaker going forward so I didn't want to put it out there without your consent. Also I do personally feel like you did something special here. Thanks again Jim and bravo for this design / tuning for modern music making / reference. I have never heard anything like this!

Thanks, Chris, for the kind words. And, by the way, the BePure 2's can be ordered with passive radiators as an add-on if desired.
