I assume you mean the IXL's. They dont need much power to get loud. I only give mine 400rms each and they hit a 141.0db.

It will be like nothing you have ever seen in a speaker before! Just thinking about this blows my mind.

Agreed. Even if you could it would change things so drastically that you would no longer have a IXL. And that would be a pitty.

I dont think there is. In order to get a coil similar to the SPL series in there would be a very hard thing to do. Theres just not as much gap space in there.

The IXL's will clearly tell you what they like and dont like. In my extensive expierience with these drivers, they do take slightly more than rated power as long as it "Clean". I wouldnt run them there daily though. I metered my 2 IXL's on 750 rms combined and did a 141.0 legal. Now when I uped the power to 2000rms I did a 143.0.

Will this work in a sealed box and what would the minimum box size be as i'm thinking of going with 4 of these driver's... Kevin You may want to pm Mark. I know he is doing some changes on the IXL's and he can tell you what is best for them.

Why tuned so high? Hows the low end extension? I got a 10" that I will be building a box for in the girlfriend's car. I am still deciding on which tuning for her though. It was a tester box. Just to see what it would do. I would recommend 35hz for daily driveing. Perfect tuning IMO,

IMO that box is too small. It should be at least 1.4-1.6 cubes after displacements for optimum efficiency of the IXL 12. I believe the 1 cubic foot box was for the sealed box requirements. Thats where I come in... I spent way to many hours playing with that program........very cool program once you grasp all the tricks.

Nice job! I too used the same Speckled paint on my port. But mine was the Granite color. You are right the stuf smells Yummy. I dont know what they do to make it smell so good but I know Mark gave me a few odd looks while I was painting it. I was enjoying it WAY too much. But I think I paid $8-9/can...that stuff gets pricey fast.

The IXL drivers as a whole are very efficient drivers. I have my IXL 12's running off of 400rms each and they get crazy loud. But they blend in seamlessly if desired.

hey, I'm not from Winnipeg although I've spent plenty of time drinking there, at least before I turned 21. The old bugger was reffering to me....LOL But Mark threw some crazy stuff at me when we first discussed this project......the mans an inovator at heart. I put nothing out of the realm of possibility.

Hey..........Hey............Heeeeyyyyyy! I told you before.....I'll be there for assembly....and to help this time......

Thats only the start guys. IMO marks high level of ingenuity is going to shine through on this project. Stay tuned.....I know I am.

I am not sure exactly when. Just please be patient.

Please be patient. Mark is currently away on vacation. I am sure answering his emails will be a priority as soon as he gets back.

I dont know if linking to another forum is frowned upon here or not but I'll link to it anyways. There is a fellow on Canadiancaraudio.com that was mentioning he changed from 2 12' SSD's to a single 15" IXL and here is the link, Canadiancaraudio.com

Ya that testing session was pretty crazy. I couldnt believe it took that power. Fun Times!

Well my pair hit 143db on the termlab with 1200rms between them. I've put 1200-1400rms on one ported IXL before and as long as you know what you are doing it shouldnt be a problem.

I have had a pair of IXL 12's sitting around since last summer. With the DBDrag coming up locally in a couple weeks I felt it was time to get my arse in gear. Heres the Basic design with the exception that I decided not to do a driver flush mount and therefore increased the width of the top port piece from 4.5" to 5. This box is 3.2cubes net. We did an impedance sweep and its exact tuning is 33hz. Two weeks ago I got my pieces cut and asembeled. Sorry I fogot to take pictures of the bare box. Nothing special though. But Heres the finished box......I previously had an eD 15 in a 2.5 cubes @ 27 hz box in my car and it did a 140.6db on 1200rms. After only a few hours play I can say for certain that these are louder on only 800-900rms. And they sound better too.

Although my car hates me now. Two broken tweeter cups, a broken rearview mirror and broken sunvisors. There was a whole lot of vibrating going on But it was fun!

143.0db @ 54hz at our 2x DBdrag yesterday.

All I can say is DAMN.....you should see his workshop! M5 euphoria.

I did a 140.7@44hz in a 2.4 cube box that was tuned to 27HZ on ~1200rms....... And the driver was inverted as well. If yo have a bigger/higher tuned box.....I believe mid 140's would be possible. My initial conclussions are that my Pair of IXL 12's are louder. We'll find out Sunday if I am correct.

Of the IXL's I have had 1-10", 1-12", 1-15", 2-12". All on the same amp. All the single driver systems were seeing ~1200rms, And the 2-12's 900rms combined and the dual 12's are louder.

I havent had any problems yet. No chuffing or port noise. And I used WINisd to design it using the IXL's specs and the port velocity was within aceptable limits.
