I have had almost every high xmax klippeled to find out the competition's true parameters. Every driver that had multiple progressive spiders had roughly 19mm of one way movement within their recommended power limits. Xmax (BL rated) which is what everyone uses isn't even physically measured anyhow it is figured via formulas calculated into Klippel's system. I won't provide info on other manufacturer's drivers that I have paid to have tested, but there are several well know drivers that can be seen at car audio mag's turitorials. I don't pretend to know everything about transducers, but I have surrounded myself with the top engineers in the industry in hopes that some of their experience will rub off so that when my drivers are debued I won't have a skared reputation.

So I presume you understand music is dynamic and doesn't play at Fs long enough to be a concern. Yes 10 percent is acceptable by ALMA. However most manufactures will have body FO and spider deflection tests performed on parts before and after break in periods to adjust their products for their expected T/S changes. By my math 10% tolerance different plus an additional 10% change is a 19% difference from the original T/S parameters. And the fact Klippel recommends a break in period before testing pretty much says a good break in period is an important play on parameters.

They will break in hower if take a new sub with a 1500 watt rms rating and a 30 min xmax. That sub is designed to cool the coil with cone movement. If you are putting 1500 watts to that new sub and it is only moving 15mm how effectively is the sub cooling the coil. This isn't the case for every driver and who really plays their system full tilt ALL the time? So there shouldn't be a problem. But I believe in Murphy's Law.

Breaking in a normal sub can change t/s parameters up to 10 percent. Anybody that has any experience wit IA DP's can tell a noticeable difference of both stiffness and cone movement on power after they have been played with recommended power over a period of time, Aka breaking them in.

You have to remove the seat back. About 6 bolts and you'll gain about three more inches.

It'll fit this ain't my first rodeo

Build the box to slide thru the seat opening.

Why is the xcon and BL even being compared for loudness. This is like comparing a BL and a N2 BTL for loudness. These two drivers are two different "levels" of drivers.

I've got one or two in the shop I could let go for 200 shipped. Flushed baffles, kerffed ports

Umm.. Get a piece of cardboard make a mock-up box. If it fits make your enclosure that size.

You'd never know the difference unless you are chasing numbers.

Any resin that you will find retail will not help airflow b/c 99% of all resins have a wax additive to make it easier to sand. The wax will make for more surface tension than the mdf unless of course you sand the piss out of it. As for doing it for strength, resin will decrease the tensil strength of MDF because it causes the fibers to swell and separate before the resin cures.

I have never used anything on the inside of my seams however the tools I use allow me to cut perfectly straight cuts so I never have gaps. If needed I would use liquid nails over caulk. Reason being wood is a porous material and will hold moisture. Caulk being a rubber will not. This will cause the caulk to seperate from the woodunder extremely high humidity conditions. This won't happen with the liquid nails.

I would highly recommend calling Brian Schmitt and putting his install tools and supplies on the site. There is no one that offers quality install products to the DIY'ers

Best place on the net for USEFULL information.

Don't ever use silicon in a box. Caulk is ok but not silicon. It uses the same chemical compound used in foam surrounds. The fumes that it expels can cause surrounds to deteriate. Kinda like mixing paint thinner with paint, they both use the same base so it breaks down the paint.

Hot glue never failed in several hundred that I've built.

Nice job for a DIY'er. It does however irk the piss out of me when people runs their wires through the port. Besides that, clean job.

They will fit however a cubes box will not fit. You are going to need a few fabrication skills to work around all the odd angles under the seats.

What vehicle do you have. I will more than likely know if it'll fit or not

We can't tell you if it'll be loud enough for you. We can however say you will not find another woofer in it's price range with the same output and clearity.

You will get the same quality sound from each driver. Think of the icon as a v6 mustang and the xcon as a v8. Basically the same machine however the xcon will provide more output being it has more motor force and xmax, but like the v8 it'll take a little more gas (power) to get the extra output.

Maybe it's comic relief but if you touch the biblical looking fellow with the sheep it links to Charles Darwin.

I've got a IA DP and DR motor. $75 for the DP and $50 for the DR shipped

How many spiders are on these sub's?
