Wrapping power cords and interconnects with copper foil.
@richardbrand  I think many folks posting here enjoy diving into the physics and engineering of the media and equipment that deliver sound in high fidelity. Their curiosity may be driven by the product  of such engineering as much as their love of... 
Wrapping power cords and interconnects with copper foil.
@richardbrand Agree that right angled cables minimize transfer of electromagnetic signal... Parallel cables promote transfer, much as transformer or RF coils are wound in parallel with each other.  But... for the whole group.... do want to remark... 
Wrapping power cords and interconnects with copper foil.
Thanks!!! for possible great idea to resolve a similar issue. I was considering aluminum foil. When we added two Dolby Atmos "height" speakers to our theater system we got not so loud, but annoying, 60Hz hum from the height speakers. At first I b... 
Can a power amp have too much power, risking damage to a speaker?
Thanks iad for nuancing this discussion! I'm no longer worried about. having an over-powered amp, as long as it's clean power driving my speakers and as long as I don't drive my hearing to deafness.  For my latter concern, I'd advise all to monit... 
Can a power amp have too much power, risking damage to a speaker?
agree... with your math😁. And will not even approach 130db in our theater.   
Can a power amp have too much power, risking damage to a speaker?
waytoomuchstuff: old enough to be familiar w the Bose901power issues.  To mijostyn and others who warn about TOO LOUD sound: We use an audiometer to monitor our listening room and most of our listening is below 70dB; if we are watching an action ... 
Can a power amp have too much power, risking damage to a speaker?
Thanks all for contributing to my education. I play guitar and 5-string bass and have one Fender Pro tube amp with twin 10" speakers and a Fender SS Bassman with four 10" speakers. Guitar amps and speakers differ from high-fidelity amps and speake... 
Can a power amp have too much power, risking damage to a speaker?
Thanks! mijostyn!  I follow some Audiogon discussions, but this is my first time to submit a query. Impressed that there are folks out there who as OCD perfectionist regarding good audio as I!  Based on this experience, I'll likely join some other... 
Can a power amp have too much power, risking damage to a speaker?
THANK ALL of you for usefully responding to my query. My overall take-home: an underpowered amp driven to clipping seems more likely to damage a speaker than clean power that controls the linear motor of audio transducers. An amp driven at its upp... 
Can a power amp have too much power, risking damage to a speaker?
Thanks much Mike for that info! I'll look for an amp with much lower powered if I get speakers with limited power handling capacity.   
Most underrated female recording artists..
Linda Ronstadt hands down!  Just listen to her discography.   
Speaker design, KenjiT and others.
What useless Mental-M!  ALL Sound is by-definition PERFECT.  Sound: compression and rarefaction of air within the spectrum of human hearing— let's say between 25 - 20kHz.  I have three "transistor" radios: my Koss, my old GE and an Eton with 2.5" ... 
dose anybody know where to find a firmware upgrade for Velodyne DD-Subwoofer
I have a very nice DD-18 that still has ver 1.2 firmware. I too, would like to upgrade to 2.2.xxx.So disappointed that Velodyne has abandoned customers that brought them to the dance by spending $5K or more on equipment. Wish them-- and the compan...
