    Speaker upgrade uncertainties (Focal Aria 936)

    Maybe the Crown just runs the fan from even a moderate volume level. There's a lot of stuff packed in that small chassis. The EVO #4 being same driver configuration and newer design I'd think could be pushed as much as the 936.

    Speaker upgrade uncertainties (Focal Aria 936)

    Logical question but this loudspeaker engineer says it doesn't really work like that. Power handling is very complex but I would distill it as "You can't have too much amplifier power so long as when the music distorts you TURN THE VOLUME DOWN immediately." It's worse to try and crank it up with...

    Speaker Break-In and Environmental Measurements

    First is that you do get some quick initial break in of the spider (I'd add that maybe a tiny bit of surround, depending on the type). Now, he mentions a driver going from 50 Hz down to 40 Hz, that seems crazy extreme to me and I never measured that much but hey maybe he made a design like that...

    Transmission-line speakers

    Irving "Bud" Fried! And the racetrack woofer, first before KEF? Or was it a KEF woofer?

    Speaker Break-In and Environmental Measurements

    @Dumu is correct, no they don't, presuming you mean at the factory. Nobody has time for that except maybe some tiny brands. While some of the various factories I visited in Japan and Philippines and China were doing 100% QC at customer demand, it was a frequency and/or impedance and/or...

    Advice on a sub please

    So if you put on your most bass-heavy music and crank it up, do they distort? Are the cones moving like nuts? - If so you MUST get a highpass filter in there, which whilst your Densen looks very flexible I don't see any amplifier input to accomodate an external highpass crossover. Does it have...

    JBL 800 array pair with SVS sub

    These seem discontinued (??) and used prices reasonable. They are unusual looking what with the naked vertical horn-is that why you like them? I would expect them to be well designed, albeit for something with a large horn the sensitivity seems lower than usual.

    For large room: do floorstanders provide benefits over standmounts even with sub?

    Well then as someone may have already mentioned, the floorstanders will be better. This is presuming they have more woofer cone area than a standmount...they will often go to 3-way with a dedicated midrange which can be superior to the usual 2-way in a standmount. the 2-way will inevitably have...

    Need Speaker Advice – Budget Setup for 20m² Living Room

    Are you opposed to an external Bluetooth adaptor? (Which would mean the speaker would need an additional RCA input). Or small external streamer like a WiiM which *might* deliver better sound via Spotify Connect (with only the Spotify compression, and not the Bluetooth compression on top, is what...

    DBA (Double Bass Array) - marketing?

    Yes! But so impractical (aka "pain in the butt") to do correctly, that it is never done. Maybe I will start a service to come and while the owner is away make changes to the audio system on random days, to see if they notice.

    MekedeTech DUDU7 Android Head Unit Review

    Oh damn I gotta schedule a vacation to do that! Sounds simply great...less rain in summertime??? I'm not enthusiastic for such in the rain although we LOVED a run up to Eskdale Tarn through pouring rain in England's Lake District. I need a better shell with a bigger brim!

    JBL BassPro SL2 Under Seat Slim Subwoofer Review

    Oh quite possible. I've posted elsewhere my work buddy made some 5.25" prototypes for Alfa Romeo, and we were quite shocked their in-car measurement was flat to 20 Hz! You could not crank it up at all at such low frequencies but there was a LOT of cabin gain.

    JBL BassPro SL2 Under Seat Slim Subwoofer Review

    Don't confuse a mountain-shaped frequency response from this sealed (??) enclosure with the one-note bass from a bandpass enclosure with maybe a similar looking response. From long work in car audio I'd say what is happening here is the super small box shoves the resonance frequency way high...

    Snake Oil Department, Top This

    Just because products are expensive doesn't make them snake oil. Oh sure there is a LOT of baloney out there in audio-land, but for some time now the global trends across all industries has been ever-more-expensive products to sell to the super-rich. Just the other day I was reading a story...

    Most watts per dollar?

    Amp power specifications are tested with continuous signal into resistors (and in the case of some cheapie brands apparently subject to a lot of debate about their veracity). And out of a lot of amps I either measured myself or have seen tested other places like here or Stereophile there have...
