  1. As stated above, don't re use your old crossover network for different speakers, recipe for lack lustering sound. Is 2.5" your max depth, or can you go deeper? What other speakers have you heard in the past?

    I am! I had some noise issues, but left it on the back burner while I did everything else. I thought the ms8 was causing it, but it turned out the gain was set a little high on the amp. Weird because if I turned the volume on the ms8 and hu to 0, the noise was still there. Only way it went away was if I muted the signal with the ms8. Finally I unplugged the inputs on the amp, and noise was still present. It must have been boosting the crap out of the floor noise level? I figured turning the volume up higher on the ms8 or headunit would do the same, nope. Anyway, I got that fixed today. I've had the 3-way in for a few weeks, then pulled the pillars out for more work. Last two weeks has just been doors and kicks. Either setup sounds good, but the tweets on the pillar definitely helps with the stage height. Depending on where I cross the mids, I can raise and lower the stage height by quite a bit. I've been using a shallow slope between the mid and tweeter, seems to blend everything together, more natural. I thought it might cause some issues like comb filtering?, but I don't seem to notice. Next month I'm probably going to try some 4" tb bamboos in replacement of the L4s, and see if I notice any difference.

    -Audio Engineer's Reference Book If I'm reading that correctly, the absorbent material would help attentuate the panel resonances and standing waves, and it allows the inside temperature to remain nearly constant. So the reduction of standing waves causes an increase in the propagation of energy, which results in a dQ without the concomitant dT? while the box without poly fill would experience changes in T without changes in Q, caused by dP Also, the sound is slowed because the medium is more compressible than air alone and also more dense? I'm not sure what any of your terms such as dQ and dT are referring to. For this scenario: The polyfill changes the interior "air operation" in the box. Allows for the temp. to stay consistent, instead of rising. Lower temp = lower speed of sound (velocity). I don't know how the temp. change effects how the enclosure acts, sorry. Polyfill also diffuses standing waves (resonance), which could reduce sound coloration, but I don't believe that's the reason why it makes the enclosure's volume more effective. I could be wrong here, but I think it's just another issue. I know in HT, multiple subwoofers can be used in a way to create interference that cancels out standing waves, thus improving the FR. dQ= change in heat dT= change in temp Im just trying to understand this from the things ive learned in my physical biochem class but idk enough about waves to really grasp whats goin on Is it the temp change that has the most effect to cause the slowed wave or the change in medium through which the wave propagates? I see the ds as deltas, meaning change, but didn't know Q stood for heat, and so on. Not sure which. I do know sound travels faster in liquids and solids then air. We'll have to do some more reading.

    I have an online collection. Ill send you a pm later.

    I'm still just reading tid bits from books, certainly not a reputable source.

    It still mentions the use of fiber for damping the standing waves, but I believe that's mainly just for reducing enclosure resonance & sound coloration.

  10. Quit using the word: "Substage", it's making me batty.

  12. "Gain is 24v" what?! Your signal voltage isn't that high, perhaps you mean the voltage on the output side of the amplifier? Either way it's meaningless, especially considering you haven't stated what amp your using. Turn the gain on the amp all the way down. Turn the remote bass knob & bass level on hu all the way to the max. Turn the volume on the head unit near your max listening volume, start turning the gain up on the amplifier until you can hear distortion, then turn it down slightly until it goes away.

    I love it when my math book tells me to do something, but doesn't show any examples.

    I like the corner area, more space to lay stuff out when studying.

    I don't have room for stuff to collect dust. Only thing I own, and rarely use is my tv and xbox 360. Haven't used either in probably four months.

    I guess I just don't have the same feeling for collecting electronics, as others do.

    Because the quality was very good. I have a small collection myself. But do you use it all? Or simply look at it all in a display? So you'd rather pay $800 for something modern that a 80's amp will do for $200? I don't understand wanting to spend more than $200... If you notice, I said collect. A lot of people seem to buy old amps just to have them sit in a basement, but not use them.

    On occasion this older guy next to me in calc leans over out of his seat, and startles himself. Music, year 2012: I would insert the blowing up head icon here, but it's too much of a pain in the ass to find now. *sighs*, bad mood.

    You can thank the board update, lol. I haven't had it happen yet, but I've noticed sometimes when I post it'll just load and load and eventually quit. When I hit refresh my post has been registered. Yep, that pisses me off, 90% of the time it makes the post, and keeps loading, but today I had a long drawn out post, submitted, and boom, gone.

    meat either. Listen to this song for a minute or so: https://www.box.com/shared/static/zzcbyduvxcsb2xqe3up2.mp3 It has this sound like something dropping / clankling every thirty seconds or so. I was listening, and thought someone in the other room behind me was fucking around with a beer cap and glass or something. I swear it sounds like it's coming from behind.
