Welcome to the IHoP

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.

Let me answer that with a question. How can standing waves effect volume? Perhaps the ideal gas law can help. Just to save you the wiki, Pv=nRT. P of course by default is instantaneous and therefore frequency dependent. That you've "conquered" above, but the addition of standing waves would affect the interior enclosure pressure how? Think conservation of energy here and then apply the two together and realize you've just justified an answer.

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.

You will notice a difference, but do yourself a favor and process to your liking and then compare. Need to apple to apple it to appreciate the overpriced nature of the L4.

i've noticed this as well with shallow slopes between mid and tweet. actually running my w4's without a LPF with the tweets picking up around 5k sounds good.

my transition between mid and mb is limited to a single slope, however.

Generically speaking I much prefer shallower slopes. Specifically speaking nothing general ever holds water. My expectation with the separatoin between the mid and tweeter though is that it will surely help blending. May have some negative affects to the stage height, but IMO frequency response ALWAYS should win over staging....just another reason SQ competitions are regularly ridiculously stupid.

I have a steep slope between the sub and ex-anarchies, at 80hz, and still I get them extending too far at times. When I raised the subwoofer level (not bass level) on the ms8, it still increased the amplitude going to the ex-anarchies. So I did a little eq, raised the gain on the sub amp, and lowered the subwoofer level on the ms8. Seems to work better now.

Then I have a 18db slope between the ex-anarchies and L4.

Once I get the tweets back in I'll have to try some more combos.

Don't assume you should use the same slope on the HP and LP between the anarchies and L4's. Regularly mixed slopes can win.

[///M5 2,833]

I like them, but I want to compare them against some $30 drivers, and see if their mighty price tag is really worth it.

too bad the w4 titanium are out of stock, bamboos probably aren't too bad though.  i doubt the L4s will be better then either...

The titaniums are a WAY better driver than the L4. More limitations, but far superior in nearly every way except the ease of integration.

And I cleared out the entire house with my gas

I'll certainly tune all over again, listen for a few weeks, drop the L4s back in, tune, and listen for a few more days.

Ah fuck, don't bother. Just put in the TB's, fall in love and sell the stupid HAT crap.

Yep, just haven't tried raising the xo point yet. When I bumped the L4 up from 400hz to 550hz, it seemed to improve the midbass, throwing more of midbass frequencies in the direction of ex-anarchies and not L4s. I still want to try a shallower slope and see how that sounds, but I'm definitely using a steep fucker between the sub and ex-anarchy. Gotta keep it from jumping outta the door.

Without a doubt the most obvious and logical place to use a steep slope is to protect from overexcurion. No matter the style of driver.

Why the fuck can't I post unless I quote and do it in a new window?This also means that if it is your tweeter you need to protect you "get" to do it as well. To me though that usually means you made the wrong compromise on driver choice.

If my tweeters could talk: "C'mon, throw shit at me, I don't give a fuck."

I'm sure they are overkill since I was originally using them in a 2way crossed down to 1900hz, but now I have tons of headroom.

IIRC, I have them crossed at 7500hz and 12db.

L4s have no issues playing that high, and way higher, but the tweets add a little "airiness" and "bright" sound to the top. Plus they also raised the stage height from being mounted on the a-pillars. If I raise the xo point between the L4s and tweets, the stage height will lower, but not by a lot, and like stated before, the shallow slope really blends them together quite nicely.

Board update has really tweaked some stuff up.

I'm planning on taking Physics next semester, but the prerequisite is physics from HS, which I never took. Perhaps I can fudge it by reading a few books over the next few months.

12dB is not shallowIMO L4's shouldn't play up to 7500 *hope you are underlapping* in your installAlso curious what you mean by "airy". I've read that a lot in tweeter reviews, but really don't get it. Definitely perception, but I've tried to understand what that means multiple times and just flat out don't correlate anything with the way tweeters play to airy.

That is not how I formatted that. I seriously cannot post unless I quote in a new page and no formatting follows

I think the ms8 has 6db, haven't tried it yet, just another combination to throw into the mix.

When I vent my kicks, I described the change in sound as airy, and adding the tweets seem to add a "sparkle" more so. Like that? "sparkle" Just imagine what that sounds like.

Only thing I can think of to explain it is imagine shaking a tambourine. Very detailed, crisp, but not hash. Adds more liveliness to the sound.

I had one long drawn out post the other day, submitted, and it disappeared. Only happened once, but it made me rip my shirt off, turn green, and throw automobiles around.

That's what I'm thinking. Generally they already do a quick review when the class starts out as well.
