Given they are actually available... should I add them to the comparison chart?
The only reason I'm asking... is that even though that chart is solely based on manufacturer specs... we seem to get a lot of people seeing it more of a recommendation chart. It isn't... it's just a quick comparison of manufacture's specs.
Normally I'd just add them, but there seems to be enough of scepticism around the Element Design units... that I'd thought I'd see what direction you guys would like to see the chart go in?
Technically, the only driver's I've tested in an IB are the AE IB15... ROb

We should only add drivers when we have hands on info about them.
Our ED info was based on long discontinued models. On numerous forums there are quite a few posts complaining about the 'new' ED products since the company has changed hands. So I'd leave ED off the list

Hi Everyone,
Just an FYI - I sent out two MJ-18's to David last week for his testing, as per the thread discussion. Hopefully he will get them soon and try them out.
Oh, and all the specs you folks see on the Mach 5 site are generated by me. More results are forthcoming.
Best regards, Mark

I am eagerly awaiting the arrival of these drivers and really look forward to seeing how they perform in IB. I would imagine I'll have them by the end of this week or the beginning of next, so I should be able to post the results of my testing within a week or so. Thanks again to mrogowski for being so helpful and willing to let us test these things out for IB!

So I'd leave ED off the list Hi Thomas, Could you elaborate on this? I've searched, and I can't seem to find any credible negative comments about ED. With the group-buy pricing available through various forums, the $/liter ratio is the best on "The List" by a large margin, and they look like they're reasonably well put together. The drivers look promising, and they're available now, so they're pretty attractive as far as I can see. What am I missing?

Quite sometime ago (on our old forum) someone ask me about ED drivers. I'd never heard of ED so I goggled it. I found a company with no products in stock (everything was a special order), and a forum that was a literally dog fight between angry buyers and whoever owned ED.
Goggling ED now, I find the posts on the current ED forum start in Apr of 2004. So the data base I read must have been purged.
If the current ED drivers and their reliability are good, then we can put them on the list.
Note that I've never been a big fan of large poly cone drivers since they're the least ridged cones available. We had the original AE IB15"s (they had a poly cone) on the list because many people wanted the cheapest drivers possible and at $99ea they were the lowest price drivers around.

On numerous forums there are quite a few posts complaining about the 'new' ED products since the company has changed hands. So I'd leave ED off the list ED is still owned by Ben Milne. Ben does change suppliers more often then he changes his underwear. They started with Destijl Engineering (regular cone with a teal "E" logo), switched to TC Sounds (flat cone subs), then Image Dynamics (silver cones) and now build in-house. If anyone wants to try the 16kv.2 (15" sub), they are still on sale for $90 each for the dual 2ohm VC model until supplies are gone. This model has been discontinued. -Robert

Just wanted to update you guys so you don't think I'm slacking off. I received one of the woofers a couple of days ago, but the second is still nowhere to be found, and the last tracking info on it is from the day after Mark sent it to me. So unfortunately it seems to be held up within the postal system at the moment. Anyway, I may end up playing around with this one and seeing how it performs if the other one doesn't arrive soon. I'll keep you guys updated.

Worst case, I'll send him another one... but using a different carrier!

Hey everybody, good news! My wife just called me from home and said the sub arrived a little bit ago. Horray!!! I will get some testing done this weekend and hopefully have some results by Sunday. Stay tuned! David

In addition to the sound quality would you please make note of build quality?
I am very interested in an 8 IB setup and these would be great if they are of good quality and sound.
I'm not expecting miracles just good and reliable.

Drum roll please... Okay, I started off my day going to Wal-Mart...oops, wrong story. The 18” woofers for 50 bucks each, that’s where we were at... As you all know, I received the 2 test woofers earlier this week. I have observed, tested, & played throughout this weekend and here is what I have come up with. First of all, the woofers arrived well packed, but in a box that was just roughly fabricated. The woofers themselves were wrapped in plastic within this box and that’s about it. No frills at all, just a brown box with no markings. Next, upon inspecting the woofers, they appear to be very sturdy and well built. The surrounds are big and thick and the cones are good and stiff. Again, no frills at all. Just a very plain basket, black and gray with no markings. This thing looks like a man’s woofer. Here’s my best analogy. My current 15” woofers with chrome baskets and dual voice coils are like a Honda civic with a hopped up VTEC, whereas these 18s are more like an old primer gray Dodge Charger with nothing but cubic inches under the hood. I have to say, the one thing that feels a little cheap on the woofer is the spring clip for the wiring. First of all, it’s probably for a 12 gauge wire or so, which is no problem until you are wiring two together in parallel. It’s a little tough to fit two 12 gauge wires in there. It’s also a little flimsy, so I was very careful when inserting the wires as to not brake it. It really feels like a spring terminal for a 6X9 or something, not really an 18” sub. Next, I built a pretty cheesy 20” x 20” manifold, but it’s solid. It’s in the same location that my current manifold was in which works real well, right between my mains. I got the subs installed in the manifold and bypassed my BFD so there is no EQ at all. Just a straight signal from my Denon receiver (80hz crossover, everything set to small) to my Nady XA900 to the subs. Next, I set the level with my SPL meter. I went ahead and set it about 7 DB hot just to make sure they would handle what I was throwing at them. The next part was easy. I pulled out all of my favorite demo stuff, DVD’s and CD’s, and started listening. Now for the real drum roll since this is what you guys are really waiting on… Long story short, I was simply blown away with what I was hearing. I have owned a Paradigm PW-2200, dual SVS cylinders, Sunfire True Sub, & my current 4-15” IB, and these 2 18’s are the best bass I’ve heard yet. I really hate to sound this strong about it since this review will probably be the deciding factor for many purchases, but I can only report what I am hearing and post test plots so that’s what I’m doing. The concrete cracking in War of the Worlds DTS was scary, seriously. I will say, at extremely high volumes and the SPL about 7 DB’s hot, I did hear a very slight bottom out once, but again, this was at very high SPL levels, way louder than I would ever listen to. As far as music, everything I threw at them sounded awesome. The AC/DC kick drum has never sounded better! I could go on and on about all the test scenes and demo music I listened to, but I think you probably get the point and I don’t have much time left at the moment. I will post more later, and feel fee to ask any questions you may have. Here is a quick test plot I did, one near field and one from my seated position. These actually tested out almost identical to my 4 15’s, so I think any nulls or peaks you see are pretty much room induced. Also, the near field peak at 34 hz changed as I moved the mic closer, so it's apparently induced by the wall next to my manifold. Another huge thanks to Mark for agreeing to this testing. By the way, I have not emailed Mark back, so this is the first that he will read about my experiences also.

Fantastic!
I'm guesing that you were throwing a 4 ohm load, bridged, from the amp?

One more quick note, the test plots were done with my old style RS SPL meter and I used the newest corrections that were posted on this site several weeks back.
