they aren't the most efficient sub i've used especially not the 12 but the 15 does very good with less power. The 12 has a stiffer suspension so maybe it just seems less efficient cause it can take a pounding on it. I've thrown 1500rms on a 12 Gen 2 Mag and still couldn't get it to step out and right now I have 1200-1300rms on my 15 and it loves it. In a sealed box I get high 130s to low 140's depending on mic and thats behind the seats in a sedan. SQ is very nice on the low end but does not have the same SQ as say the IDMAX or RL-p which has a little more extension into the 80-125hz range. The sub loves the 35-60hz range. Depending on what you listen to i'd go with a 15 or a 12. 15 I prefer on almost anything but if you could afford a pair of 12's would be killer. I really liked the sound of the 12 in my Alero Coupe I had on rock and stuff, the 15 does well though. Suggestion though, if you like music get a frontstage that can actually keep up with the sub. I've been listening to "The Postal Service" and song #9 even my 3way frontstage gets outdone by the sub.
What subs do you know of that will move more than that with 450rms?
Also, which version were you talking about not being the most efficient?
Also, SQ could be effected by the amount of power you are throwing at them. It is hard to maintain perfect SQ when giving 1000+ watts to a driver. It is very possible you are driving the subwoofer past the 24mm of Xmax that is has. So that could be part of the reason.
I meant subs that are sold these days. And I just think the Mags are up there with any sub in effieciency. I can't see how they could be considered not to have great efficiency, if he was talking about the newer version mags.
it is quite efficient compared to the Gen 2 but the 12 really shines with power more. You may get by with less power especially in a ported box but in a sealed enclosure it does much better with more power, much better. I mean when have you seen a sealed 12 with 1200watts outdo a ported 15in sub off 600rms. Subs like the Rl-p and Ov.2 seemed more efficient with the power but its doesn't really matter, the Mag is a killer sub. And i've never bottomed out the sub yet showrides, you know how I am with the Mag. The Mag is a killer SQ sub but excels at the low end for the frequency range and not the upper end like the Rl-p or Ov.2. This isn't a bad thing at all for a sub is only meant to play down low like 80hz and below and the Mag is a killer at a very important range of 30-50hz. I think I noticed peak output in a sealed box in the 33-38hz range, well atleast my car's response.
That sounded good to me. And mine are sealed with 450rms each, and I think they really pound. But I haven't wired them down to .5 ohms yet and tried them with about 1200rms each, so they could be CRAZY loud with that power. So for now I will take your work on that. But now you got me looking forward to giving them some real power. But I do think most people will be perfectly content with the output even with 450rms each.
