Power Acoustik MOFO-122X 12" Subwoofer

When technology advances, products do as well. Does Lamborghini need to refine their cars every 2 years? NO, they do because they can. After 6 years, it is time for a change. Say "See Ya!" to the old MOFO, and welcome the new MOFO-X subwoofers! The new motor is refined and increases efficiency dramatically! MOFO-X subs use a non-pressed pulp cone for durability and smooth low bass. Like the original MOFOs, the new models use an aluminum dustcap that couples to the voice coil former and extends over the cone. Why? The fins brace the cone and eliminate cone flex during high excursion. Since the cap is aluminum and coupled to the coil former, it acts as a heat sink or heat extractor. Using the latest materials, the new MOFO-X subs yield superior performance!

Enclosure Recommendations

All enclosures should be made of .75" (3/4") material only. When possible, make the baffle 1.5" (1-1/2") thick and add .75" (3/4") to the depth of the enclosure to compensate. All volumes INCLUDE vent/port and subwoofer displacements. DO NOT change the volume unless you plan on adding a substantial amount of bracing. For added performance, applying a coat of fiberglass resin to the interior walls will greatly improve sealing the enclosure. Adding a thin layer of poly-fill will improve response by smoothing out enclosure reflections.

12 2ohm dvc

still breaking it in and so far on 800rms its flat out hammers. shouldnt have any issues handling the 1200rms i plan to throw at it at a later date after i build a new enclosure to spec. dont be afraid to use this sub bang for the buck its a hit.

Ive had 2 of these for about a year now coupled with the BAMF 5500/1D wired to 1 ohm just a little of half way on the gain pushing approximately 1300 rms (JUST A NOTE THE 5500/1D DOES NOT PUT OUT WHAT IT CLAIMS, NO MORE THAN 2000 RMS!!!)
Best dB metering is 145.2 @ 43hz with a pro box giving each 2.5ft.
Budget system that I am impressed with. Getting 4 new MOFO's as this sub can not be re-coned, Only bad thing about them. Great sub for the price and people have been shocked when they hear that its only 2 12's.
Do not play for long periods at high gain levels as the sub will heat up quickly.

Mofo 122x perfect sub

Well I purchased this sub 2 days ago and installed it today in my Lexus LS400. I got the sub hooked up to a BAMF 2000/1d Monoblock amp at 1ohm and let me tell you, this sub hits really hard. I got it in 1.5 cub ft sealed box that I also purchased from Sonic, in my opinion that's all you need I strongly recommend this sub. I'm sticking with power Acoustik from now, nice product and affordable. The first is Sonic Electronix the shipping is always in good hands and right on time so special thanks to SonicElectronix for their service. i gotta go now, and for those that are getting this item i hope you enjoy it.

Very nice Punchy, Thumpy and Thundery type bass

I know that the Subwoofer Enclosure (Sub Box) plays a big role in subwoofers performance but a lot of credit goes to this sub. First off when you open the box up and take the sub out you will think you ordered a 25 pound dumbbell, yes it really fells like it weight about that much. The look it excellent and has nice covers to cover up screws from showing with you install it into a Subwoofer Enclosure. I have a 3400w boss amp pushing it and it is handling it very good running at 1ohms. I have it installed a 1.5 Cu FT Sealed Box that has Poly Fill in it also and when the speaker plays it HIts Very Very strong. If you like that bass where it fells like someone has a big Hammer and banging it on the back of your FRONT seats then look no farther.

Other notes:
It HIT the Lows very nice
Having it in a ported box may make it even louder.

All i got to say is man this thing hits and it gets loud... have it running on Rockford Fosgate p1000.1 @1357 rms @ 1ohm . just make sure you have the right amp and power source to run this mofo. Thank again to Sonic Electronix super fast shipping, great products, great prices, great service
thats why i shop at Sonix. THANK YOU!

Great sub

Awesome sub!! I have it extremely under powered, I have about 30% power going to this thing and it shakes my car, turns heads and barely hear myself while yelling. Looks good and sounds amazing. Time to upgrade my amp to get full rang :)
