    Impedance Anyone?

    Bit of theory around (until is descends into usual asr thing) https://www.audiosciencereview.com/forum/index.php?threads/nc252mp-class-d-vs-a250w4r-classab-burst-measurements-into-4ohm-2-2uf-load.43162/ all in all 40A d class amp is OK.

    Impression of my new Power Sound Audio S2112M subwoofer

    Did you already order second PSA? :)

    Impedance Anyone?

    https://www.stereophile.com/content/martinlogan-montis-loudspeaker-measurements similar results. No idea about electrical properties, but [in my case] relieving internal amps from 60Hz down helped a lot through the entire FR.

    PBK: ARC For ML Subwoofers & Masterpiece Speakers

    Technical Q - what would be the delay introduced via stacking of DSP Processing? [probably nothing really dramatic as long as you stay with IIR filters of both ARC and MiniDsp] but I would still expect couple of miliseconds. I think MiniDsp adds one layer for each processing step? No idea...

    PBK: ARC For ML Subwoofers & Masterpiece Speakers

    TBH - then stop wasting your time on M, W, XXX or whatever patterns and ARC. No offence meant - ARC is great in its class, but it really does not compare. Trinnov is all about running all the bells ;-). Trinnov can do it all 10x better and in 15 min. I am just bit surprised - here in Europe...

    PBK: ARC For ML Subwoofers & Masterpiece Speakers

    Frequency range is good place to start when doing before/after comparison and can tell you whether you are going in the right direction. My 2 eurocents 1) ARC is using IIR filters - I would say it is OK until approx. 150Hz, then the phase shifts introduced by IIR filters can start to become...

    Expression 13A, Source, Motion series Atmos tops and sides

    Another interesting update from Trinnov, looking forward to individual excursion curve [limiting the corrections that system is allowed to do] and also really curious about pre-ringing [as I have done some experimenting with advanced settings already]. I think they have really woken up, as they...

    Setting Correct Frequency Range

    As a general advice [for every DRC] - look at potential dips in sensitive region - in your case it will be around crossover frequency, as Audyssey is quite aggressive in boosting [8dB, if I remember correctly], but Ios app gives you very limited control about what Audyssey might be doing. If you...

    Well, my BF 210 has a big problem and I purchased it new in July 2021. Here is what it is doing.

    Bit more on the topic - I have been in direct contact with Trinnov (one of few companies with that level of support). Long story short - as many subs as possible, ideally with some level of symmetry and better not that from each other, than in the corners. still passive treatment above 100Hz...

    Well, my BF 210 has a big problem and I purchased it new in July 2021. Here is what it is doing.

    A) there is nothing like Trinnov 64, max is 48 ch, with up to 64 outputs (used for bi-tri-quad amping some channels.) B) talk to people at Trinnov as you might be in for a nasty surprise next year, they are very helpful. C) BF will NOT work with their new game changing Active Acoustics. This is...

    Show me your pets!

    This young lady is obviously banned from all the cables etc. she does not mind, anyway

    Well, my BF 210 has a big problem and I purchased it new in July 2021. Here is what it is doing.

    @ttocs look for Plane Wave Bass Array (PWBA) from Neumann. Even spacing of approx 70cm is required.

    Well, my BF 210 has a big problem and I purchased it new in July 2021. Here is what it is doing.

    While their service is commendable, I see it more as a prerequisite to even consider to buy anything in the future. https://www.rythmikaudio.com/G25HP_specs.html if you believe you need dipole subwoofer, here is the one for you, with servo driver. Actually dipole is not that much about room...

    Well, my BF 210 has a big problem and I purchased it new in July 2021. Here is what it is doing.

    Anyway, once you clear basic performance thresholds for a sub, it is all about positioning, room acoustics and DRC implementation. Even more so with multi subs. we do not get PSA, HSU or Rhytmiks here in Europe. There are some companies that make subs - Ascendo is considered high-end. ML...

    You should check the history of the land, where your house is built. It might be benign manifestation of some bored ghost ;-). Good luck, and wishing you a speedy recovery. Probably with amp module change you have reached the limits of what is serviceable at home. Let's hope ML customer...

    Adding a sub woofer with a pair of 15As

    Easy one, smash them where they fit ;-) Jokes aside - there is whole science behind multi-sub placement and lot of theories how you can do it - Velti, Geddes …. I combine PWBS Neumann planar wave - which asks for spacing of subs across the front wall (I also utilize esl13) which creates...

    Adding a sub woofer with a pair of 15As

    Yes, I had a chance to listen to the TRINNOV demo in Barcelona - and it was out of this world. Cant' wait to have it at home in the couple of months. I think my setup is not bad, with all the room treatments, electronics and Trinnov, I have ruler flat response time domain out of textbook, but it...

    Anyone use the wireless kit from Martin Logan? The SWT-X Wireless Subwoofer Kit

    stock power cord is L shaped, so no issues here. some people believe in aftermarket cords to improve the sound. ( I buy shielded cords for everything (supra) same as I have in my walls. I do not claim any sonic benefits.
