Electrodynamic

The prototype is in flight right now after being assembled and is scheduled to arrive at our facility tomorrow. The reps and I have known about the arrival for a few days but I'm posting this now to let you all know when the proto is scheduled to arrive. I'll take pictures and get them posted by this weekend. This weekend will also be the initial testing of the new Mag, and it's going to be a tough test! We're going to position the new Mag against the old/current Mag and our testing will be published complete with numbers of the comparission. Anyway, the new Mag proto is coming soon!

Nope, the Mag will not handle 1300 watts daily. The new Mags can handle up to 1000 watts in our recommended enclosures. I'll post up the basket dimensions tomorrow.

Guys, please reference the other topic for answers to questions like this: http://www.soundsolutionsaudio.com/forum/i...showtopic=14098

You don't need that much power (at all) to get them to perform at their peak. In 1 cube sealed (not 1.2 or 1.5, etc, sealed) or 1.5 cubes ported it shouldn't be a problem for a pair of them to take twin 1000D's. We're going to do some high-power testing soon, and we'll update the forum with the results.

Some of you have seen pics or drawing of the new Mag's basket and read about its shallow 5.5" of mounting depth. You might have also heard about the super-small enclosure requirements. As much as I love my current Mag 12's, and love beating the absolute piss out of them, I have also given a lot of though as to the design in general. The current Mag (the one's we are sold out of) are a decently efficient, are extremely versitile, and have the ability to soak up a LOT of power. That last sentence has a key word in it - soak. I can count on one hand how many times I have bottomed out my pair of Mag's with a 3200 watt amplifier, two big batteries, and an HO alt. And even then, I did it on purpose. Now, I want everyone that has downloaded a copy of WinISD (can be downloaded for free at www.linearteam.org) to do the following: Load any 12" subwoofer and put it in 1 cubic foot sealed. Put the input signal at 1000 watts. Pull down the toolbar and take a look at excursion. You won't see the excursion plot go over 38/40mm of total travel. ...yes I used WinISD, but I used it because it is free and it works very well to show cone excursion per given application. What people are failing to realize with most super-subs is that they are paying for something that will never use. Sure you might have 27-30mm of one-way travel, but how much of you are actually using that travel? Also, how much power does it take to get to 54-60mm of total trave in 1 cubic foot sealed? Do the homework in WinISD and you'll be very surprised. That is why the new Mag's and BM's have been totally re-designed. In practical applications, you aren't getting your 12" subwoofer to move over 20mm one-way with 1000 watts in 1 cubic foot. So why pay for all that extra weight and inefficiency if you don't have to? Not to mention the fact that a "super-sub" is almost always 6.75" or more deep. I have attached a screen shot of the excursion plots for the JL 12W7 and the current SI Mag 12 (the one's we are sold out of) in 1 ft^3 sealed with 1000 watts of input. The JL is the yellow plot, the Mag is the orange plot. Notice how much cone excursion is going on above 20 Hz. The verticle plane is total excursion in milimeters and the horizontal plane is frequency.

if he hasnt said whos car it was in I doubt he will show pics. is it still untouched or has he worked on it a bit? I know the pics I saw of it looked like it needed a bit of work on it It needs some work. What he needs to do first is see if the thing runs or not. On the stereo side of things it needs work too...but not much. The hard part (2" thick MDF dash, solid metal doors, lexan windows, 2-4" thick MDF enclosure, etc, is already done. And with Jake's help, I don't think power is going to be a problem.

While we were testing the new Mag we decided to play around with some old BM 10's. We put eight 10's in an SPL car that had no alternator, 5 batteries, and a single SAZ 3000D. The first burp was in the 154's but we ended up getting it up to a 157.2 without too much trouble. Keep in mind the batteries had no charger on them for most of the test and when a carger was on them it was a little portable (about 12" by 9") charger. Oh yeah, this was all done on a Term Lab meter.

Hoss really didn't meter that well oddly enough. The truck's system would take your head off, but it just didn't meter well. His truck felt like it was doing mid 150's but only metered a 148. Haha, now that I think about it, he shook his screwed in and glued in port wall loose after a few months.

Yep, I got your email. I'll burn the tracks tomorrow and see if I can give them a listen before I go out of town this weekend. No release or order dates as of yet. We're still ironing out the details for production and the last thing I want to do is lead people on with a random date. PS: You can make the enclosures around 0.8 cubes each and add polyfill to make it 1 cube.

Cool, I'll be looking forward to your tracks. If you can fit 3 cubes, you can fit 3 Mag's...or 6 BM's.

I think he'll be OK with it.

No, it was a walled off car - pure SPL vehicle. They were being burped at 55'ish Hz.

Sorry about that, you're right, it is the proto specs. I'll post the specs later on tonight for you. Your box builder still needs to build it to 2 cubes tuned to 34 Hz though.

Tuning lower will NOT be better for rap. A 34 Hz tune dips down to 20 Hz with zero loss in a car. The T/S's are still on our web page. Go to the bottom of the BM web page and there is a link. Port area should be between 20-24 in^2 per driver.

Holy crap! Nice car and a very nice install!! Also that's a nice web page for your own stereo install. But yes, in 1 cube each, 3 Mags will handle 800 watts each. I'm going to do more power testing this weekend after I up the power in my gutted Civic. We'll also do some Termlab testing. We didn't get around to upping the power this past weekend because the HO alt stopped working so we had to swap it out. This time the factory alt went back in because it provides such good output at idle. That, and I don't have a problem with power due to the two Powermaster batteries behind the seats. Anyway, back to the Mag. The driver will handle anything you can throw at it. It plays back music a lot better and more accurate than the current Mag. You can send me an .mp3 of the music you're talking about so I can burn it and give it a listen, but I'm already confident that the Mag will follow it. 1 cube is ideal for 800-1000 watts. If you have 500-800 watts, you can up the enclosure size to 1.2 cubes if you desire. It is not necessary though - the driver is just a tad more efficient in the larger enclosure sizes, but it can't take the power...hence, the above recommendations. I'm recommending sealed because it sounds so damn good in sealed! But, I know people are going to want to port them, and the Mag will work great ported as well. This weekend we'll throw it in a ported enclosure and see what happens on the mic. 1.5 cubes ported to 32 Hz (that is what I'll recommend) will handle 1000 watts with the proper subsonic filter. That is the only ported enclosure we are going to recommend. In retrospect, 1 cube is the only enclosure we are going to recommend. And our warranty only extends to drivers that are put in our recommended enclosures. You can't throw the driver in 1.5 cubes, send it 1500 watts, and wonder what happened - the driver won't take that kind of abuse and we know exactly what kind of power it will take in what enclosures.

Us and us. Just not yet.

The driver can take 1k watt thermally in 1 cube sealed, which is why our recommended and specified enclosure will be 1 cube sealed. Not 1.1 or 1.2, but 1 cube sealed. If you absolutely HAVE to shove 1200 watts to a driver, don't choose the new Mag. But be aware that the new Mag is more efficient than the current Mag and doesn't need 1k watt to reach full potential. I wonder how many times it's been stated, no 15's. No 15's. We do have 2 15's left in stock though. The first $475 each gets them!

I don't mean to sound negative, but read the other posts about the Mag. The other posts answer all your questions. There will be no 15 inch version. The older models handle more power. The older models aren't any more durable, but they handle more power (i.e. over 1000 watts RMS). I have sacrificed power handling for superb SQ, and it's worth every penny!!! And this is an upgrade from the current model. PS: as the original post states, only this one pic for now.

Cool man, I'm glad you like it. I hate to say this because it might make me sound stuck-up, but your response is pretty normal. Enjoy the sub my man!

I suppose I can go ahead and leak that the new Mag's are going to be below $275 direct. ...shipped.

Haha, you get me that girl in your avatar and I'll drive out to AZ for a personal demo!

The driver is here and we have done preliminary testing on it vs. the current Mag. All I'm going to say before our first full listening test is that it is a lot more efficient than the current mag and plays a lot lower. I'll post more this Saturday or Sunday after we do some hard in-vehicle testing and more in-room measurements and tests.

The pics have been up for a few weeks now. I didn't post them on here because I want more people visiting the web page. PS: The proto may or may not have come a day early. :D Stay tuned to this thread!!! No, I'm not going to post anything yet, but I'll post something tomorrow.

Put this in the appropriate forum please.

Haha, my post did have a the plane, the plane! kind-of feel didn't it?
