Talk but not walk?
Hi Guys
This isn't meant to start a fight, but it is important to on lookers. As a qualifier, I have my own audio forum where we report on audio issues as we empirically test them. It helps us short cut on theories and developing methods of listening. We have a wide range of systems and they are all over the world adding their experiences to the mix. Some are engineers, some are artist and others are audiophiles both new and old. One question I am almost always asked while I am visiting other forums, from some of my members and also members of the forum I am visiting is, why do so many HEA hobbyist talk theory without any, or very limited, empirical testing or experience?
I have been around empirical testing labs since I was a kid, and one thing that is certain is, you can always tell if someone is talking without walking. Right now on this forum there are easily 20 threads going on where folks are talking theory and there is absolutely no doubt to any of us who have actually done the testing needed, that the guy talking has never done the actual empirical testing themselves. I've seen this happen with HEA reviewers and designers and a ton of hobbyist. My question is this, why?
You would think that this hobby would be about listening and experience, so why are there so many myths created and why, in this hobby in particular, do people claim they know something without ever experimenting or being part of a team of empirical science folks. It's not that hard to setup a real empirical testing ground, so why don't we see this happen?
I'm not asking for peoples credentials, and I'm not asking to be trolled, I'm simply asking why talk and not walk? In many ways HEA is on pause while the rest of audio innovation is moving forward. I'm also not asking you guys to defend HEA, we've all heard it been there done it. What I'm asking is a very simple question in a hobby that is suppose to be based on "doing", why fake it?
thanks, be polite

Mike, You've got to live under a rock or something. I don't even own a TV, but I know who the "cash me outside" girl is. https://www.facebook.com/realbhadbhabie/ 2 millions followers, pal. You're not even keeping up with drug-addled white trash from Dr. Phil. |
I find modestly plump women to be the best compromise between diffusion and absorbtion. Fat men don’t have the curves to diffuse properly and skinny women have small cross-sections and weak absorbtion properties. However, if you have enough skinny women that works well too, and they allow for more granular placement and adjustment. I try to keep 10 or 12 on hand to place in the corners, behind the speakers, and around the wall behind me. If the room is still too reflective, terry cloth robes help. Unlike sweaters (or ugly Christmas sweaters in keeping with the season), robes can be opened and closed both for better sonic and visual properties. Silk and lace seem to have virtually no useful sonic properties, unfortunately. |
Hombre, I think you need to start looking at actually measurements instead of taking a guys opinion as fact. Virtually all speakers are designed to be driven by voltage sources which is why virtually all amps are designed to be voltage sources. Dynamic speakers definitely don't act like resistors. Most are moderately reactive and many are very reactive. A speaker that's acting like a giant capacitor is a VERY reactive speakers by definition. Capacitance takes current to drive, and as it does so it rotates the phase of the current demand away from the phase of the voltage. Very capacitive loads aren't easier to drive. They're require more feedback in the amp to control. |
Hi Mikey! What an irrelevant set of questions! This kind of questioning gives great insight into your complete lack of technical knowledge. Highly reactive speakers are tough loads to drive. That's just a fact. Lots of reactive speakers sound good with the right amp. I don't personally like planar speakers. They don't sound realistic and they have serious dispersion and room interaction issues. Many are also unreliable and require somewhat frequent and expensive rebuilds. I almost bought a pair of Maggie's a few years back just because they were very cheap, but opted not to. None of that has anything to do with their electrical behavior though. |
