Massive xl122 hippos

Let these babies break in good and you'll get the best bang for your buck I started with some Kenwood's then I moved to some power acoustics mofos now I'm with the hippos One of these 122 hippos is more powerful than the both of the power acoustic mofos I have two hippo XL 122 hooked up to cea rated amps .... I'm running 12000 peak but my gain not even 1/4 and even at low levels every thing shakes .. You can feel your pants vibrate as you walk up to my suv... My Windows shake so bad I turn it down haven't even got a chance to push them yet!!! You are definitely Going to need the big three done If you don't know what that is sonic has a video on it giving you details also you're going to need good size I am running to 50 ferret caps and hi input alternator .... I don't have an extra battery yet but that is my next step because these babies to take some power I am looking forward to my next upgrade though I am addicted to the base and I just got to get bigger and bigger so far these are the best I've had

Good value

Good budget spl subwoofer. Needs a large box if you want a better range. Heavy. Seems well built. Rated for 2k rms. Goes into distortion well before that.

Hits hard. Good value replacement but power hungry.

I am using these to replace 2 bag end subwoofers D12E-1 that I blew running 2000 watts thru them in home theater. So decided to upgrade to a woofer I can throw a lot of power at in the same box. Box volume was 2.88 just shy of recommended 3cu ft, but added acousta stuff to help woofers feel like they are in bigger box. Wired both woofers in series for 8 ohm load, however measures close to 9ohms, since crown k2 amp was only stable to 4 ohms. Basically sends 1650 watts to the pair of woofers in same box in this configuration. A bit of a challenge when you have two dual voice coil 2ohm, Wish had 4 ohm voice coils, but could not think of configuration to get to a 4 ohm load with all those connections. Trade off is less power but better dampening and control. The subs definitely produce some volume and low frequency. However, feel I need more power to get bigger impact--had a couple movie scenes where signal was clipping and amp could not get all the peak power needed. I have two sub boxes with two woofers each wired the same on different amps. Since I am not too concerned with music and more for effects as a home theater subwoofer and the price point, I would buy again.

Massive Audio HIPPOXL122

This thing rocks it is by far the best speaker I have ever had and for the price you can't get anything else with the same rms power ratings. I have a hifonics Zeus 3200 pushing it and now my neighbors don't like me anymore because they say that they can't hear their TV when I am home
