The ported box they tested it in was actually smaller than what we were thinking about recommending, which actually allowed the driver better power handling. However, like Chad and Jim stated, the driver is better suited to sealed, which is what the Mag was designed for anyway. PS: Neither Jim or Chad harrped on it heavily but they did casually mention that the Mag handled every bit of the 800'ish watts they had on tap and was plenty loud enough. When I was testing the Mag in my Civic (1.2 cubes sealed coupled to a SAZ-1000D) it was vibrating/moving my hair...and I have short hair with gel in it.

Sweet! I was wondering how it was going to look because those scion's are tiny in the hatch area, but man that should turn out killer!

Thanks for the review Jim! PS: No pics ... well, maybe a frontal, but that's it. There are a lot of changes that are happening on the back of the driver, so no pics will be posted until the final proto gets here.

Thanks, I'll get it fixed ASAP.

HOLY CRAP!!! I was gone for half the weekend and I come back to this! 5 15" Mag's...man, as if 4 wasn't enough. You are a sick, sick man Marcos.

The BM is technically more efficient from the 1w/1m standpoint, but not by much. The BM and the Mag are both inefficient on the 1w/1m front, but they are efficient when it comes to output (read the paper on subwoofer efficiency on our technical web page). The new Mag and new BM are both a LOT more efficient than the previous models regarding output from small sealed boxes.

This thread will provide all of the details about the new BM's (sizes, shapes, colors, vc options, enclosures, etc): The new BM subwoofers are a shallow design with a tiny mounting depth of 3.5 inches! The drivers will utilize a flat honeycomb nomex cone Inverted foam surround Available in 12" only and in dual 4 Ohm only 500 watt RMS power handling in the recommended enclosures Sealed enclosure size of 0.5 cubic feet. XBL^2 motor with ~13mm of Xmax

PS: It's in the new thread I stickied. http://www.soundsolutionsaudio.com/forum/i...showtopic=15422

After driver displacement (the Mag displaces ~0.08 cubes).

if God made a component set, they would sound like that Took the words out of my mouth. LOL!! They weren't that good! The tweeters were the short-coming to the component sets. They still sounded good, but they weren't what considered a really neutral sounding tweeter. I've got the tweeter I would use in the next components is sitting on a shelf in our storage facility. It's a VERY VERY good sounding tweeter, but it would raise the cost of the components an additional $300.

Here it is: the official thread on the new Mag 12 D2. The new Mag D2 will be available in 12" only. It will also be available in Dual 2 Ohms only. Recommended sealed enclosure volume is 1 cubic foot. The enclosure recommendations are after port and driver displacement. The new Mag will displace 0.08 ft^3 The new Mag D2 will feature: 3" voice coil an XBL^2 equipped motor 5.5" deep mounting depth Motor is inside the basket, hence the shallow depth Paper pulp cone Rubber surround Sewn-on vc leads Flush gasket (no holes showing) 1000 watt power handling in recommended enclosures

I suppose I should start another thread and sticky it and lock it with the information on the new Mag's. I think the problem is there are too many threads about the Mag and people hop in and don't read the other threads. Good, consider it done. Now, wasn't that a good talk? I think so.

This weekend my ass is in the my woodshop down here finishing my BIB's, hopefully Hicks can hang onto it until next weekend when I'm back in VA AH! Jim...Jim Jim Jim. You disappoint me. (kidding) Chad can hold onto it for that long if he wants. I was hoping to get it back sooner though.

Yeah buddy! The new heatsink is sexy! Jake came up with a great design. The cooling fins underneath the top of the amp is just genius.

Eh, I've got our current Mag that we've retired for our library but I really don't want to lug that thing around in my hatch. For sealed use the new Mag kicks the current Mag's butt in LFE too...so I got kinda spoiled. I'd rather go without for a few days and work on installing the amplifiers...or at least working on organizing them to see where they'll end up.

Yep yep, I just sent it out a few hours ago. Chad should have it by Wednesday and then he and JimJ are going to try to meet this weekend to do some sealed testing. I was sad to see it go...and it also reminded me of how critical a sub is to a sound system. Damned Audax 5.25's!!

Haha, no problem.

Awwww. So cuuute! Haha, nice job man. And sure sure, you didn't mean to do it. ;)

Your best bet is a TL, like John said, or to tune it to 27 Hz in 2.5 - 2.8 cubes. The 12" Mag wasn't designed to play to 20 Hz flat in a home environment. That's where the 15" Mag's come into play - they will play wickedly low for HT use. Which version do you have? If you have the claw version (it literally says "Magnum" on the dustcap), your tuning is going to be limited to the 30's, not the high 20's like the last generations.

Thanks for the reply's guys - they were all spot-on. 1200 watts on a previous Mag 15 is just fine. Can it sound good? Yes. Can I get it insanely loud with 2k watts and a fart box? Yes. Will it sound good in the fart box? No. Just like Stratus said - mid 140's from a single Mag isn't un-common...all while still sounding better than anything else out there.

I'll listen to anything you guys send me. I don't have anything by D'Angelo.

^ What he said. Ok, instead of having you (or anyone) model something up to help explain what I was about to explain I'll model it up real quick and post a graph. I'm going to use a PA 12" driver in 1 cube sealed and the new Mag 12 in 1 cube sealed to show you what Jake and I are talking about. Like Jake said, above 200 Hz, sensitivity means a lot if you're talking about a midrange. When you're after output below 100 Hz, high sensitivity is a bad thing. Like Jake said, high sensitivity drivers have moving mass's that are too low, Xmax's too low, and usually Qts's that are too low to provide any real output in the subwoofer region. Concerning the driver you are talking about (the DIY), take a look at the Great 12 Challenge results. The driver didn't fair well at all. It's a neat looking driver, but output wise it provided very little and proved to be a brittle driver (mainly the cone). The light moving mass approach is a good one...if, and only if, you have the other parameters in check so that you still have good output. Like Jake said above, and I've said before, if you have that kind of mass you need a high Qts in order to regain output down low. Low Q, high BL, low moving mass drivers are not good subwoofers. Anyway, here is a graph of an Eminence 12" high-efficiency woofer (97 dB) against the new Mag 12" (86 dB). Both are in 1 cube sealed. The green horizontal line is 0 dB, the red trace is the Mag and the blue trace is the Eminence. The Mag's F3 is 40 Hz compared to the Eminence's F3 of 79 Hz. The thing to keep in mind is that there is a clear difference between efficiency and output. Two completely different things. What the new Mag was designed for was output in 1 cube sealed or 1.5 cubes vented. It wasn't designed to hit a great 1W/1M number because if it was designed for that, it wouldn't produce any real sub bass.

They might be able to play that high, but not without encountering breakup first. Anyway, I was experimenting with such a high x-over to see how the driver sounded. It sounded so good with it being that high I just left it for a while. The x-over is now at 100 Hz, and will probably go down to 80'ish this weekend.
