I'm so glad I'm done with the find my perfect sub obsession and am finally happy.
There's nothing magical about Mags. I had the v3, with the way people were talking about it here, I thought my ears were going to experience the equivalent of a deep blowjob. Especially for the outrageous W7 tier price tag. In reality, it was a decent sub, not any more impressive than the Oz Matrix Elite I had in before it (which cost me only $160 by the way). Maybe it just wasn't the right sub for my application, I wanted a sealed box sub that got low and loud, kind of like a W7. It got loud, but was extremely peaky, and did not get very low since the punchy bass was overpowering. In addition, it sounded very similar to the Oz sub and really wasn't worth the price tag. I figured, eh, maybe it's just a better ported sub. In the meantime I looked for that sub which fit my needs, I found it in the TC 12 OEM. I don't think anything in particular is better about the TC 12 compared to the Mag, except that it was designed for home audio, and therefore it was much flatter and had more extreme lows. It also had more linear excursion and similar power handling. Did I mention it cost only $200?
I gave my Mag to a friend for his birthday, who decided to try it ported. He put it in a very well built box tuned to 32 hz and fed it nice power. It wanged, but the SQ really wasn't even close to good sealed setups I've heard. In fact, no ported setup has sounded as good to me as a good sealed setup. I don't give a **** what the people here say.
All in all, just a very overrated and overhyped subwoofer there for anyone except those who want to wang in ported enclosures and care about SQ, but not an overwhelming amount.
I have a feeling the v4 suffers from the same syndrome, just very overhyped, a maybe fairly good sub, but nothing magical.
Stop thinking subs you buy from these internet companies will produce magical bass that you can't get anywhere else. It's just bass. Find a sub that has the frequency response characteristics you enjoy, along with the ability to play as loud as you like without distortion, and you'll have a winner. Very simple formula. You won't hear 90% of the ******** people talk about here. In fact, they love the Mag because you can't hear it. Claiming a sub has good SQ because you can barely hear it is like saying a luxury car is luxurious because it isn't driving over 60 mph. I think Mercedes owners would be pissed as **** if their cars didn't go 80+ when they felt like pushing it.
It's awesome to not give a **** anymore and just tell the truth as I see it. Nuthuggers will attack me from all angles, but I probably won't even remember that I wrote this rant by tomorrow.
