Massive has really out-done themselves with this one because the build is CRAZY! Overall build quality is pristine and it looks amazing. Performance-wise, it is well within its own realm to be comparable to Orions, Sundowns, DDs, DCs etc., but SQ, in my opinion, is a notch higher than most! Bass is deep and surprisingly sharp, especially in a ported box at very low frequencies. I recommend this sub ONLY to severely addicted bass heads who enjoy ear-ringing, hair crazy, deafening bass, 'cause you're fetting nothing less!! Worth EVERY PENNY!! :)
The important thing to remember with sub woofers is that you need an adequate enclosure as well as adequate power. I put this sub in a 4.2 cuft box ported at 32hz with a 2400w rms amp with the sub wired down to 1ohm. To say it slams is an understatement. The sub is also very "musical". Usually with very powerful large subwoofers you lose some of the bass response in some types of music such as rock or electro. This is not the case with the Hippo. Obviously it's not as responsive as an 8 but its the best sounding and loudest 15 I've ever worked with. Take this sub, put it in a good box with a good amp and I guarantee you won't be disappointed. It sounds like you've got 4 12's in the trunk. Insane bass is an understatement. Mirrors on the car are useless at full volume.
Well one year with this thing and its a beast . Nothing short of awesome and there's nothing I play on it that sounds less than crazy. People get mad when i pull up to them in a light and the best thing is that i have it half way lol. I got it hooked up to a power acoustik 5500 at one ohm and it plays all day. A must for anyone and the amp to cause the planet audio 5000 watt amp i had before burned in one week.
Got it hooked up to 5000 watt cerwin vega amp wired to it's own 5000 watt battery and it SLAMS!! I ha not hooked it to 1 ohm yet I gotta change alternator first but I'm pretty sure i am in for another shock this 1 15 hits harder than the 4 12s I just had in my back seat now my back seat is open and box is in the back port facing roof and it bends the roof and doors AT HALF WAY!!!
