Why do you guys pursue a flat frequency response when you buy a subwoofer?
Contrary to Miller’s myth many sub designers are very aware of Earl Geddes seminal work on multiple subs What myth? Hello! Tomic601! What myth??? Where did I ever say many sub designers are not aware? There’s a function, cut and paste. Please use it to substantiate your insult or withdraw it. Thank you! OP you have three subs. Thus this thing is a whole lot easier for you than most. Simply put all three in one room and find out for yourself what happens. tomic601 not letting you off the hook. I know perfectly well the last thing I ever do is promulgate a myth. Serious insult buddy. Prove it, or apologize, or be forever branded a liar. I think we all know which one it is, but I’m giving you the opportunity to pretend you read me wrong. |
There's always a different way to reply. Could be he was so enamored with the alliteration and proud of coming up with Miller's myth he just had to use it even though it had nothing to do with anything I'd said. Could have asked about that a lot of different ways. I'm not comfortable having people, since you don't like lie let's say make things up about me. That's a misperception he had the opportunity to correct, and he chose to double down on the insults. Not exactly comfortable with that either. Mainly though I'm far from thinking it had anything to do with misperception. I think he perceived what I said just fine. But rather than dealing with the substance of what I actually said he thought it better to belittle it as myth. That's my perception. If its wrong, he's free to clear it up. I'm certainly open to that. |
The minute you put that flat sub in your room and take some measurements, it is anything but flat (it's a rollercoaster with all kinds of peaks/nulls etc, EQ to the rescue).....So, why do you dudes continue to look for the flat line? Good question. This dude used to think like that, until he started reading the other guy, aka Duke, aka Audiokinesis, and that guy led the dude to reading some other guys, none of whom think like most dudes but instead actually studied the problem. All this reading led to actually for the first time understanding the problem, which yes most dudes do get wrong but this guy now does not. What the real sub guys know that the dudes do not is what Duke alludes to above as "an interesting challenge". You are right deep, put one sub in a room and you get peaks and valleys all over the place. Move the sub, peaks and valleys move but are all still there. You move the one sub around endlessly. Been there. Done that. So, to review, one sub no matter where you put it produces lumpy bass. Moving the sub only moves the lumps, but never gets rid of them. The solution, which you can only shake your head at the brilliant simplicity of it all, is more subs. With more subs each sub has to put out much less volume. So the lumps get smaller- and there are more of them. Which when you get enough small lumps turns out the result is pretty smooth. This brilliant idea of using lots of bass sources distributed around the room is called a distributed bass array or DBA. Duke the speaker guy makes em. He calls his version the Swarm. Mine is based on his. https://systems.audiogon.com/systems/8367 Notice there's three different types of subs- 2 ported, 2 sealed, 1 isobaric. There's other guys here with DIY DBA, and other guys using the Swarm. The one thing all us guys have in common is we love our smooth, articulate, deep and totally awesome bass. That and, we wish more guys knew about it, and we could all be less like the other dudes. |
