Nice video! I think I might pick up one of those DD-1's for the shop. PS: Thanks for the mention in your video. Made me feel all warm and fuzzy!

That's plenty of room for two 12's in a ported enclosure. I would contact DC Creations or RAM Designs about enclosure plans and/or building the enclosure for you.

I am fully aware of that. That's why I said what I said. However, it is what people don't understand which supplies the illusion of having those response curves inside of their car. Sure you can compare subwoofers to see which one will play lower in the same size box but again it is in a test chamber, not in real life. Actual responses in real life are anything but close to what WinISD shells out. The program is very good for determining port length in a vented enclosure though.

I hope you are not stating that the Obsidian woofers are designed by the same person who designed the Skar woofers because that is completely wrong. If you are listening to your woofers in an anechoic chamber then definitely look at the WinISD graphs. If you are not, however, add in a +12dB/octave gain at ~45 Hz and you will have an estimated in-car response.

And that's exactly what they were designed to do - operate over a very large bandwidth while sounding good and getting very loud if need be.

Yes indeed. He puts up respectable numbers but the camera does not do this system any justice.

Send it again and I'll keep an eye out for it. What is the email address you are using?

I'm doing fine Ryan. (PS: Nice to see you around!) I wasn't really keen on the idea of opening this up to everyone but if it raises money to help out with MS I'm all for it.

It looks like a solid box volume and tuning frequency. I don't know where the idea of X in^2 per ft^3 started but it is not a very good ideology to follow. If that were the case a single port for a single 12" driver in 3 ft^3 would be 36 in^2 for 12 in^2 per 1 ft^3 which is a 3x12" port...and good luck fitting it inside the enclosure due to the port length required. That's a huge port for a single 12"! Most drivers out there can't excite that huge port area, so that huge port is wasted for the most part. Simply stick with 12 in^2 to 18 in^2 per 12" driver and you will be fine. An adequate port for the Obsidian 15's is 30 in^2, or 90 in^3 for three 15's. The enclosure you have listed above is 165 in^2, or nearly double what you need. You can go with a huge port but your bandwidth/response will suffer as larger ports tend to peak higher than smaller/adequate, ports. Or if you had 9000+ watts and were interested in competing only, then the 165 in^2 has the possibility to put up a better score than a port that is 90 in^2. For instance, with 1500 watts of clamped power using a single 6" aero port (28 in^2) I managed 144 dB in my CRX legal on the dash sealed up using a single 15" Obsidian. Switching to the 8" aero port (50 in^2) and raising my tuning closer to the peak of the vehicle (mine peaks at 56 Hz) I managed a 145 with the same power. However, increasing the power to 3000 watts saw a peak score of 148 dB with the 8" port. If I didn't have the large 3000 watts of power the huge port was not very beneficial.

Nice response curves.

Cool deal!

I just replied to an email to someone about the same exact thing. Displacement is 0.1 cube.

True. I need to host a pic of the surround on the cone to give you guys an idea about what it looks like.

Cool.

LOL! Haha, I didn't even check the date. So who brought this thing up from the dead anyway? I swear it was at the top!

First you need to let us know what your goals are and how much room and power you have to play with. Without any of those, this topic really won't get you a solution to your querry.

Very light, on the order of 20-25 lbs for the Mag and less for the BM I'm sure. Yep, the Mag weighs in right at 20 lbs. The BM's are in the 15 lb neighborhood.

Bigbang - search this forum. The prices and all the information regarding the new Mags are on this forum.

Like I said before, the 1800+ watt, power-soaking monster market is flooded. If you want a driver like that that requires 2+ cubes ported, then buy something else. That is NOT what the Mag is designed to do, period. Read what I've written before - the new Mag sealed has the output of most ported 12's. Case in point. Why go incredibly larger (most of the time over 2X the enclosure size and double the weight) when you don't need to? And if you feel that you can hear the 0.6 dB difference going from 1000 watts to 1200 watts, then by all means throw that smidge more power on a different driver. What you'll end up doing is coming back to a Mag after 6 months of fooling around with settings, making 3 different enclosures, and spending 4x the money on a subwoofer system that you could have avoided the entire time just by purchasing a new Mag in the beginning. I'm not making the new Mag a 1500 watt do-anything-you-want-to-to-it driver. The new Mag is for small sealed, phenomenal SQ, 1k watt power handling, good SPL, light weight. Period. It solves more sub-bass problems than the previous Mag's could have ever fathomed solving. Much more specific, much more wide-range problem solving.

Thanks for the replies guys. Haha, the thread got fairly interesting on page 2 for sure. I know it might seem like it's a gamble to do a small enclosure, sealed only, lightweight driver on roe and ca.com, but keep in mind that a lot of people who post about ported post questions to whether or not they can use 1800 watts on a single driver. That's not what the Mag was designed to do at all. A lot of people don't post too - those are the ones who typically ran them sealed. There are a lot of Mag users that wanted the best sound possible from the smallest enclosure possible. Listening to my customers lead me to design the next Mag for small, lightweight, shallow mounting depth, and sealed. That's what people wanted. They wanted a solution to bass without taking up the entire trunk. The new Mag is that solution. If I make a 1800+ watt ported bad boy it's going to be a 15 that will be completely different than the Mag. Like I said on ca.com, the Mag was originally designed for small sealed enclosures. Back in our beginings we thought we made a good sealed driver. Come to find out it worked really well ported. We found out why it did so well ported and continued to make it work both ported and sealed. Making it a true SQL, shove-1500-watts-on-it-and-nothing-is-damaged, big-boy was cool, but it was still a big, heavy, power hungry beast. People wanted something like that, and that's what I built. Sure it still sounded good, but it sounded good, not REALLY good. But now the market is flooded with drivers that will do what those customers want. The Mag slowly lost some of it's SQ and gained more SPL roots. Not entirely, but the tables went from something like a 50/50 split to a 40/60 split. And that's fine for people who want that, but that isn't where we are focusing anymore. It's time to take the Mag back to its roots - small sealed. ...but now the new Mag sealed is as loud as most drivers ported. And it takes up half the enclosure size. And it weighs 2/3 if not 1/2 what other woofers do. And it's 2" shallower. And it still handles 1000 watts. And it sounds better...a LOT better. I know it might look risky, but I don't see it that way. There have been a LOT of people email me over the past few years asking for a shallow version of the Mag, and when I look at the market it makes total sense to do one. The new Mag hits 100% of the design goal. Not only our original design goal back in 2000, but also our new goal for 2008. I'm stickin to it! And Chad is right - I'm an OCD bastard that won't settle for anything other than perfection. Jim knows that too. How many other companies would sit for 2 years without any product to sell because they would rather wait for the best than to jump on something that would get them by? In car audio, I don't know of any other than us. PS: Asia is shaping up nicely. (I'm in Shanghai right now). I spent all day yesterday meeting with the owner of a metal extrusion facility, eating lunch and dinner with him before making my way back to the hotel. Tomorrow I'm going to start my 3-day stay with the build house that's doing the final assembly work on the new Mag's and BM's.

The new Mag sealed will NOT keep up with a previous-gen Mag ported. Ported simply has too much of an advantage. But like Jim said, the new Mag sealed has enough output that's for sure.

Fairly well...but the power handling goes out the window.
