    Why are Speakers Concave (CBT**2 With Inverted Domes?)

    Virtually all speaker drivers are more or less concave (ok, Magnapans, Ohm F’s, tweeter arrays, excluded.) I was just reading the thread on CBTs and line array design/ theory and how they work...

    Mix and Match Subs?

    I have a JBL ES-250p sub (12”, 400 W https://www.jbl.com/ES250PBK.html). I see that JBL is offering the Sub550 (10”, 500W) on sale for $199 as a Black Friday promo. That seems like a great sub and good price. Would it be wise to mix these different sized subs in the same AV system? (I’m...

    It’s interesting to see a number of manufacturers using a modular approach to utilize modular technology like these, named, modular units in their products. Though this may be opening a religious war amongst ASR Illuminati, which of the modular amp companies like ICE, Hypex, Purifi (have I...

    Phil Spector and the Wall of Sound

    It seems only appropriate that ASR acknowledge the death of Phil Spector, creator of the Wall of Sound. Though Spector certainly had his personal issues, I think we would all agree that he was a major force in the recording industry who changed what recorded music sounded like and we are all...

    White Noise, Pink Noise or Throw Them Out?

    I just picked up a new pair of JBL's on sale and they arrived yesterday. (I just couldn't say no and had to pull the trigger, but that's another woeful story.) Unfortunately, plans didn't quite work out: the new speakers didn't make it under the Christmas Tree. Instead the JBLs were stripped...

    ZorLoo ZuperDAC-S Support?

    I picked up a ZuperDac S in February, 2020. The unit arrived with a stuck volume button rendering it useless. Zorloo promptly sent a replacement. Now it, too, has died four months later. I’ve sent several emails to support about warranty replacement. No response. Anyone else having...
