What vehicle

Is this an enclosure or just console? Go on Fishman's YouTube and look at some of his installs. Him and Brian Schmitt are about the best around making custom installs appear factory.

If that is the case I'd get a roll of protective fill like used on cell phones. If not its not gonna hold up long.

Plexi will scratch all to hell with daily use. Depending on the type of plexi used ammonia based cleaners will make it fog up. And any alcohol based cleaners will make it spider web and crack.

Is like to see pics of that set up.

No, 10's and 18's will be available on the next production order. Due to the large amount of baskets I have to order it would have put me over budget.

It's so shitty working away from home.

Post a link to the video. Was this in a shop or warehouse? I can view it on mobile.

Not even close. Even if the outlet was on a 20 amps breaker it's only getting 2,200 watts. 110volts at ~60 hertz times 20amps = 2400 watts. Anymore and the breaker would have thrown.

It's cool the used the Big Red name. Looks like they even brought back the early 90's styling on the plastic.

Yea basically, shit happens. Enclosure size and tuning effect the amount of power it can take. It's just insurance.

since all the kiddies like videos, here is the Ethos 15 on ~1,750 watts. Mind the jerry rigged set up. I don't currently have a large enough battery supply in my shop to run my power convertor on a large amount of power.

I don't believe I said linear spiders suck. Please find it and quote it for me if I did. I said progressive spiders are better for the application of a ported alignment. As I said before, a spider is a spring. A linear spider will have a smooth curve through its movement. Meaning it gets tighter and tight at a smooth constant rate until its stretched out similar to say an accordion. Now on a progressive spider it gets tighter nice and smooth just like the linear spider up until it hits xmax. Once it hits this point it gets exponentially tighter acting as a break, to help the driver from hitting hard mechanical limits if that makes sense. Given the fact that ported enclosure unload below tuning its good to use a progressive spider as a safety feature.

DOD. Isn't that some type of MIlitary popo

To answer your other question. It's obvious that if you can fit ported do so. The BP option is for folks who want to cram a bunch of stuff in small spaces.

A more reliable FEA program and also verified by hand calculations a more appropriate enclosure would be 3cft total tuned to 48 hertz puts the bottom f3 at 28 hertz and the top F3 at 80 hertz. This enclosure is more in line with the subwoofers thermal rating. In other words the driver will hit xmax at rms rating. ~1,800 watts. However it's response is 2 db down across the board. I did not post that enclosure at this time as I knew less educated people that do not know that WinSd can't factor in PeMax due to the fact it doesn't factor suspension. The posted enclosure would take about 2,500 watts to hit xmax. But again I knew Id get tons of flaming due to the "correct" enclosure being 2 db down.

Now of course I'm not going to test. I thought that's what the customer is for.

Specs for the 15 inch Ethos with 4th order bandpass option Re 1.5 ohms Fo 31.52 Qts .4429 Qes .4728 Qms 7 Vas 63.78 liters BL 15.48 T/M xmax 33mm Mms 362.9 grams Cms 70.26 uM/N spl 87.95 1W/1M Recommended enclosure rear volume 1.4 cubic feet front volume .86 cubic feet tuning 50.8 hertz bottom F3 ~32 hertz top F3 ~83 hertz The below graph is the regular Ethos 15 compared to the Ethos 15 with the bandpass option. The bandpass option sub will work in a normal vented alignment however output will suffer due to the suspension being ~1/3 softer. Therefor it will not be able to handle the same amount of power in a vented alignment.

Four of these left.

I like pics but all I see are two and the post reapeat itself three times?

Need to get u one of those cooling suits

For sitting on my ass 95% of the time it's obscene.

Last August I was getting readings over 200 on the tin walls with a temp gun. The operators are in air conditioned loaders. I only go in to pull samples. The warehouse is about a half a football field full of ground up and cooked fish that has been ran through a hammer mill. If you have ever sniffed a can of those fish food flakes you get the general idea.

You could be in a 120 degree warehouse infested with Mosquitos sniffing fishmeal dust.
