Thought I'd jump in here too, since I'm getting really close to buying a sub!
It seems that alot of people here have a helluvalotta praise for eD. I personally have never heard of them until now...are they really *that* good?
Just FYI, my reason for an 8" is space concerns...I need to keep the utilitarian aspect of my car. I was considering the JL 8w3v2 with it's box spec of 0.37cuft, but now I'm rethinking about an eD8a; same size box, but is the performance that much better/different?
Thanks for educating a car audio newbie!!

I am running 12" JL W6 v2 's and it is loud enought to hurt small children.
But I am runing it with a JL 500 amp and a farad cap ... no probs so far, no dimmed lights
Going to be upgrading the alt soon.

The 8a is slightly deeper than the w3v2, so it unfortunately won't fit in the MSP box without some work. However, if you can figure out a way to get it to fit, then it's one hell of a little beasty. The problem you'll have from that point on is that the amp that's currently there would be underpowering it, and it's mounted upside down (good way to overheat and fry the amp. So you'll have to figure out a different way to mount a better amp.

I've got a Pro5, so it's a custom install from the start. I'm looking at something in the 200-250W range to power whatever I get...should help the low-end withdraw I'm having right now...
Yeah...that should do it then...hehe! And yes...eD really is that good. I can't tell you how much I have been impressed with my sub. What a good blened system I've got in my car...it's sick...course...I have some spare wood, and I might go with a vented box, but I'm not sure. (naughty)
You can use one of their 10s and still have a very small box...you'd just have to drop some stuffing in there. But I think the 8a may actually have more output then a 10k...so it's pretty close either way. If you have any questions, go to eD's site and hit up the soundillusions forums from there. They were a really big help. You can even email the guys at eD who are super quick to respond and really helpful!
first off, ED is THAT good
secondly, you won't find a better driver for the money
you would be more than happy with an A8. if you want higher output at lower frequencies, then definintely go ported for it course here are 2 other options for you:
first, the most serious 8" sub:
shorter mounting depth, and more output than a W7
here's more info. and here's specs and how to buy.
course if you really want to "wow" people, run a couple of these 6.5"
14 mm of xmax on a 6.5"
yeah, they totally blow away koda's and 6W0's these are still prototypes, and haven't been finalized. the final ones will have x-max within 2 mm of these, depending on the final voice coil choice course the price on them is going to be about $150-$200 each, from what i've heard

I'm sticking with my JL's. My friends S2000 has two 6W0's and he meters in at a 153.1. VERY Impressive. These 8W7's are no sub to take lightly either.
some points:
1. No one here has compared the ED's 8" to the 8W7 side by stat, engineering to engineering. Some may have listened to them but I have yet to see someones transducer engineering or mechanical engineering degree. Not to mention I doubt there are anyone of us that know how to work in a transducer design application. I watched an engineer at Boston design every aspect of a magnet for a speaker (HOLY s***)
2. Most companies (unlike JL and Boston) buy damn near everything from parts vendors and do very little research and design. I don't know where ED stands but JL is all but 100% designed in house from the ground up, not just catalog parts.
3. Yes ED will save you money becuase it is direct.
However JLs cost to build is FAR less then ED or other internet style manufacturers. Even if you facotr in some reps price to vendors the JL often will be less. JL makes an obscene amount of these things in comparision and have assembly lines in house to do it. This also means quality control is in house to. JL amps are an excpetion as they are built overseas.
4. Also cosider JLs engineering staff and abilities. WHy are they not making a sub more like ED or Adire?
They surely have the talent, software, education, and bottomless pockets.
THings that make you go hmmmm?

Ok...mishter Shmarty-pantsh.
Some counter points:
1. I have a mechanical engineering degree...you want me to learn what it all means and then compare them as such?
2. ED designs their own pieces. They do have suppliers on somethings, but the subs are designed by them...just not entirely manufactured by them. Just look at subs that they have...they are different, use materials you don't find everywhere, and have some very neat ideas (like tinsle woven into the spider to prevent tinsle slap)
3. Bottom line is that JL is marked up like crazy. Sure it costs them less to build stuff...and the prices are obviously competitive if people keep buying it...but I think you'd agree that if you didn't get that discount they'd be too damn high. And as for quality control...i can show you the QC card I got from eD signed, in pen, by one of their 10 or so employees. All of their subs are assembled in house, and get full QC checks, and they all carry a 3 year warranty.
4. the simple answer here, is because ED's and Adire's still sound different. JL makes what they know...and they make great SQ subs that can still hit hard. But that being said...why are there so many brands of components out there, right? Why doesn't everyone follow Image dynamics' lead, or JL's lead, or Kicker's (blech!) lead. If so many people like Solo-barics, then why doesn't JL make a square sub? Because they have a different vision, seen?
Now...let me add something here:
I love eD for the products they make, and they price they offer them at. I love JL audio for the products that they make...but I waver once we get to the price. I'm just saying that people should explore all options because, like I said in point 4, every company has a different vision.
1: you make it sound like ED has no clue in what they are doing, yet they are winnning comps
2: JL subs are not all in house parts. while the W7 is, their other subs are not. JL didn't even design all their parts in house for their lower level subs. and they also design many parts and have someone else build them. i used to have the manufacturers and part #'s that JL buys from. i will say that the parts are available to JL only, and no one else, but the suppliers also have products that are 99.9% identical all the info i had on my home computer before it crashed was from the president of MAS loudspeakers. he was going to have me test out some car audio subs, but they decided to stick to home audio
3: no s*** but they make so many more, if they have the same % of returns for defects, they will have a higher # of returns and ED builds their subs in house. they used to have destijl engineering build part of their subs, but because of problems, they decided to build everything themselves. so it is all in house, hand built subs and to date i've only heard of one complaint on any of ED's new subs, and it was an A15 that the cone cracked, and the person got a brand new one under warranty.
4: that's like asking why ED doesn't make the exact same sub as adire
both are different. compare an ED A-series to a brahma. both have great SQ. both have great power handling. both are extremely linear. yet both are designed and built different than W7's and are still compared to W7's W7's are great, and it gives a point for other companies to strive for, or beat
i know JL subs are great. there is no arguing that. but there are brands that can produce the same results with a lower cost. and like servoeyes said, without that nice discount, i bet you'd be running ED in your car
and here's a little info on xbl2 technology that adire audio patented, and resonant engineering uses.
1: they have less than a 5% decrease in BL over 24 mm of total excursion, while the next closest kind of motor topology was only 18 mm to a 5% decrease.
2: using xbl2, you get a sub with a shorter voice coil and top plate, meaning you get a sub that needs less mounting depth. my brahma 10 has a depth of 6.5", while a W7 needs 8".
3: because of it's design they have a lower moving mass and more clearance, which means dual spiders are not required for such a high excursion driver.
