    VU Meters: Let's See 'Em!!

    Have you guys tried any software solution? The decibel app I'm actually playing with is promising: https://process.audio/en/products/decibel All other soft solutions I tried before were plugins and I never really understood how to run them in a DAW in parallel of my simple music player (apple...

    SMSL VMV A1

    Ppataki I enjoy reading your build threads so please let us know if you try. Me I'm done switching and testing amps, I have retried a pass at that for the last 2 years and the result is that I'm back with the simplest amps (Rekkr on highs and fosi on lows now). Tried a bunch of high and low...

    Wonderful discovery: A Shared Sense Of Purpose | Warrington-Runcorn New Town Development Plan For sure a Jarre’s vibe with a lot of emotions. His work was recently removed on apple music, I wish I saved more locally but they can be found on bandcamp. Even youtube doesn’t have it all, this one...

    Focal Diva Utopia

    I do love the felt, and based on the design I would not be surprised to see many variations later with these panels : wood/piano colors/fabric maybe, going into Davone look&feel.

    Horn Speakers - Is it me or.......

    These asymmetrical horns flipped on their sides remind me the car audio horns concept, like for example from Eric Stevens. They created a very strong center for all seats even without dsp, directing more sound to the opposite side. Plus, if well installed, they would take advantage of the...

    NAD C 316BEE V2 Integrated Amplifier Review

    Yes I’m surprised how good it is there, low enough for me and very constant. I knew this amp was ok, bought one on sale last year and used it few months as a power amp. Output was clean on my midbass. A bit too noisy on high efficiency drivers to use all the power, but after lowering the volume...

    Why is the car audio industry so far behind?

    I don't know about the current industry level, but in my time few years ago they were definitely in advance with dsp & multichannel. Sure aftermarket suffered with all the integration but there’s new product that can bypass all this. I had so much fun working on the car, learned so much...

    Double Bass Array (DBA)

    A lot of good stuff here: Nils Öllerer papers Even minimal number of subs seem to work, like 2.1, but drivers CTC depends of the room size and crossover. Maybe just timing differences on the rear subs could compensate the offset of the convex shape, to build a plan wave?

    Double Bass Array (DBA)

    Oh my of course what was I thinking? Cancellation has to happen at least past our head or we won't hear anything haha. Ok so it happens near the rear wall in all cases, that removes the question of the minimal distance for the plan wave to "build up. It's even better as then the rear subs have...

    Double Bass Array (DBA)

    That brings another question, maybe more important than the driver type: Is there a minimal distance for the wave to become plan, or plan enough? That could drive the MLP. What I got: - if MLP is equally distant from front and rear walls, front and rear subs need to have the same SPL. - If MLP...

    Double Bass Array (DBA)

    Mine might get lost: What do you think of using « smaller" subs for the rear array? (smaller in Xmax or Sd)

    Double Bass Array (DBA)

    DBA are always so impressive, I need to try! Since there is a big attenuation on the rear array with an MLP closer to the rear wall, do you guys think that smaller subs could be used there? (by Sd or Xmax) I want to try with 2.2 and then 4.4 subs but in theory I would need 6.6 and that’s just...

    Speakers with clay cabinets spotted

    I think it's great, maybe not hifi but very imaginative. We don’t know the context and the details, maybe the inside is heavily lined or even just with clay that does not dry. The top horn could be refined, the mid shape is strange but maybe it’s just for the support and 2nd and 3rd chambers are...

    DIY speaker stands

    I was about to build one in wood for my 3 way classic in progress, but saw this cheap ODDVAR at ikea: They’re good for 100kgs, I’ll check the detailed dimensions in the shop but I might try. Painted black, legs cut to the needed length, reversed with some concrete poured at the bottom + some...

    Going Active - Discrete parts or Hypex Fusions?

    The answer is obvious to me but I’m partial and might not understand some details of your needs. Why do you want the Wiim on both? I guess it’s needed as preamp with the fusions but seems redondant with the flex (that has coax/toslink and hdmi in). So I’m partial to minidsp for their plugins...

    Video: Development of the B&O Beolab 90

    I certainly enjoyed it, it's rare to see the whole process even including the relation with the designer. That they called « visual » designer, when it’s probably more an industrial designer (I’m picky but I was one). I was surprised by few things: - the limited number of prototypes, maybe they...

    Matching amps through measurements

    I’m guessing you don’t have a mic and rew? With an rta app on your smartphone you could measure each section playing pink noise. Phone at the same level, let’s say 1meter away. Then adjust the fosi to match or to your liking. You should see the effect of the crossover. It’s not super accurate...

    Matching amps through measurements

    if you want to level match shouldn’t you use a mic? (even a simple app if not umik/rew) Voltage needs might be very different per section.

    New VU Meter Switcher Questionnaire Survey

    I really like the lc30 but found few issues on its calibration (https://audiosciencereview.com/forum/index.php?threads/fosi-audio-lc30-dual-vu-meters.49797/post-1937397), still using it though. I will soon need 3 more so maybe I'll wait for the next one. Don't want to bother with gmail so I'm...
