Thanks for sorting it out! Really appreciate it!

That is correct. What info do you need, exactly? Don't want to post too much on a public forum...

Zachary Staat, order # is 13954. And, I did pay for the third one. Edit* Also, I have already called. I found the phone number entertaining as well, haha!

Alright. I know Stereo Integrity is related to Sundown, so I'm not sure what else to do here. Here's my situation. LAST Tuesday, I ordered an SI HT 18 D2 from Stereo Integrity. Then, on Wednesday, I ordered 2 more, since I meant to order 3 the first time. The 2 I ordered on Wednesday have arrived and are all fine and dandy. The one from Tuesday hasn't even shipped yet. I've been trying since Saurday to contact these guys about my order, since I really need the 3rd by the 24th. I can't do anything with 2 of these. So, I'm out my money, out a woofer, and out a bunch of time trying to get a hold of Stereo Integrity to inform them of their error. I'm not sure where else to go here, if someone has ANY way of getting me in touch with these guys PLEASE let me know.

Gotcha. Yeah, enclosure design is ridiculously important, in fact I'd say it's literally the most important thing. I dunno what kind of enclosure you could build to make them reach limits on 1k (Infinite baffle?) but I'm sure it could be done. Well anyway, good luck with the build, hope all goes well!

thats completely wrong Is it? I was under the impression that the sealed section brought down frequency response and cone excursion. The smaller the chamber the smaller the excursion, but the less low end response. In fact I think I have a graph in WinISD illustrating this... What is the case if not this? Not trying to be an ass, trying to learn. (: should have specified i was talking about the over excursion Whew, thought I had missed some huge new discovery in enclosure design. I don't have any personal experience with lvl6's, just took a quick look at the specs, and made a conjecture. My mistake I suppose.

I'm not sure I see why you couldn't do a BP with a lvl6 either. I mean, I use my 4th for excursion restriction purposes only (In fact I think sundown uses the same practice in their van), so even if they're stupidly stiff and wouldn't like a bandpass it's still good to prevent them from bottoming out. If they're going on 5k a pop, I don't think over excursion would be an issue. In fact I don't see it being an issue on anything under 10k lmao.

If you're doing this in a daily driver, then go with a center port. For SPL purposes I find that a driver's side port is usually the loudest, since you are usually metering somewhat on the passenger side. Other than that, since it's a blow-through, is there any reason behind not going with a 4th order or am I misreading something?
