I always find soft dome tweeters to be " lacking" in crispness.... they sound flat to me i am running 1" pure titanium domes and they are pin point crisp and crystal clear

So 100% completely useless for deadening. Ok. Don't use that.

Off axis will probably be preferred, but the baffles you made will allow you to test.

Umm, no. People are lemmings. The name should give it away for you: Bandpass. By definition (verbatim from Websters lol) :a filter that transmits only frequencies within a selected band. In other words, the box in this case becomes a filter and reduces the low frequency & high frequency output. Wider range is laughably stupid as it is the exact opposite. There is only 1 logical use for a 4th order BP and that is when you have the port fire into a cabin instead of the box into the trunk. Some cars are bass traps and you need to do that. Other than that, one could argue if you had no processing that you can use the mechanical filtering of the box to improve your overall sound but in the modern headunit there is always sub processing so that reason seems pretty ridiculous.

Windows look great dude!

Yep, same reason that idiots are building useless 4th order bandpass boxes. Either trying to copy or be unique, but almost always a monster failure.

Exactly. Lesson took half a lifetime to learn. Better than finding out at 60. :-D

I ran a pair of 10” DCON’s on an Arc XDi2000 at one ohm, 2.5x their rated power in a bad sealed enclosure. Never hurt them thermally but did cause a little trouble mechanically. The prefab sealed enclosure started to come apart. I honestly feel that if the enclosure hadn’t started to leak they would probably have been just fine. Like I said I never hurt them thermally, the coils still look like new. As a result I started designing a ported enclosure around using them on my SAZ-2000 in my Grand Prix. According to the modeling, with 25hz tuning and an enclosure slightly larger than the maximum recommended size they should handle the power mechanically. By manipulating the enclosure size and tuning I managed to put the drivers’ peak impedance right where the xmax peaks allowing them to not exceed their rated xmax even on 2.5x rated power. Of course it’s all theory and modeling so real world results are going to vary to a point but I plan on trying it out at least. My point is that if everything is good with the voltage, clipping, distortion, etc. I wouldn’t be nearly as worried about thermal damage especially if you’re talking a single 8k on the two subs, you’re only 500 watts over with the ratings and that’s never going to even be noticeable.

That is because there are a lot of stupid people. The goal of "over powering" is already dubious adding an enclosure change to rationalize it being okay is downright ridiculous. Larger amp = lower gains if you want your stuff to live. Doing something else is absurd.

I think if your not crazy with the volume knob all the time you wont mess the subs up. Most people messing up subs are clipping real bad and a smaller box isnt going to help with that. I would still go with what is recommended for the subs . Friend of mine is running 2 sp4s on 9k with no problems and his enclosure is on the larger side of whats recommended. But has the electrical for the 9k
