HIFONICS HFi12D4 12-Inch 1200W Subwoofers (Pair)

will take full 300 RMS in proper enclosure with right amp (no clipping)

love 4th order bandpass enclosures.

at least 1.5 sealed and 2 ported (each).  ;)  tune in 40s-50's and enjoy.

also do pretty well in 1.5 or more sealed.

havnt tried ported but will be doing a ported enclosure 2.5@ 33 Hz for a friend. 

will do another review for sealed enclosures

I have two of these bad boys in a slot vented sub box tuned to 44Hz with 2.6 cubic feet of air space throughout the whole box, and they are loud! You can hear my jeep coming for blocks.  I am only using a 350 Watt kenwood amp bridged, and it puts out like 260 rms at four ohms bridged so they are only getting 130 watts each.  They are REALLY loud and hit the lows like crazy.  They dont cut out or pop or anything and they make clean bass its mad crazy you can get subs like these for that low of a price.  I am getting a box for them tomorrow which is tuned to 35 Hz and has 3.5 cubic feet of air space, so they will be slammin the lows.  I am excited.  I would recommend these to anyone on a small budget, cause i dont even have a small budget and thought i would give these a try and they really surprised me.  The fact was i was scared but now i dont have a single regret.  They truly impress me and i had a 15" Fosgate T1.  They hit almost as hard, and you definitly get LOUD bang for your buck.  $50 you cant go wrong i promise.

i bought this set of subs about a year ago they work so well now that  im upgradeing my system instead of getting 2 15s  ill be gettin 2 nore of these sweet ass hifis cant wait for them to get here these are the boxes i used with setup sound good <a href="../product_3511/Q-POWER-Dual-12-Inch-Ported-Subwoofer-Box.html">http://www.vminnovations.com/product_3511/Q-POWER-Dual-12-Inch-Ported-Subwoofer-Box.html</a>

Wow i was so excited when these arrived, only have 50rms to each sub until i get my new amp and these sound great, with my sealed box i really feel it in my chest, ordered it tuesday and it came friday, cant beat the price and the free shipping, love the chrome trim.

i love these subs i ordered it on a tuesday it came that friday, hooked them up that day easily, and they sound great, only got 50rms to each until i get my new amp and i still feel it in my chest, they look good love the chrome trim, would recommend to anyone.

Let me just start by saying, am an audio enthusiast, and guru, i have had setups with 4 18"s on 15,000w, i have have super SQ oriented setups, and many, many others, and i will start by saying, these HFIs are hands down the best subs under $100 i have ever used. they are built nicely, they look great, and if you listen to any sort of hip-hop, these are the subs for you. I recoment 2.5-3 cubic feet ported, with a port tuned to 33hz, that displacement and tuning is the sweet spot for these subs, heres a crappy video of the install i just took of a customers truck with 3 HFI12D4's, on a crunch 1400.2<br /><br /><a href="http://www.youtube.com/watch?v=nm-sd6D665A">http://www.youtube.com/watch?v=nm-sd6D665A</a><br /><br />i plan on doing 8 of them in my truck (daily ground pounder) on a crescendo 3500 at 1 ohm. i love these subs with a passion, ive owned alot of them in the past, and will continue to buy them from VM. great customer service, AMAZING price, and super fast shipping, i'd be dumb to do buisness elseware.<br /><br /><br />Keep in mind, this is the opinion of a profession subwoofer box designer. also, in the video, the rear view was moving much more than the camera could pick up, it was going insane haha. 

These subs just flat out destroy anything anywhere near it's price range.  Period.  11 mm of Xmax from a $25 sub?  Hello?  90% of people who buy subs are spending $100 retail to get that.  Not to mention, stitched tensel leads, 1" wide roll surround, dual 4 ohm voice coils, to get that amp down to 2 ohms, or if you get 2, get a 1 ohm stable amp, or run the voice coils in a series making them 8 ohms, then parralell the subs making a 4 ohm load. I got 4 so far, thinking about getting a couple more, 4 under the coffee table sounds about right.  lol  They sound good in sealed, ported and bandpass, especially bandpass enclosures.  And sound good with anywhere from 100 to 300 watts RMS.  Buy some!!

I must say, That i was rather reluctant to these subs. i am so glad that i did.

I absolutely love these subwoofers as ive owned or have purchased about 8 through ebay or vminnovations and its always been a good experiance. Although for this time around I recieved a defective product and a perfectly working product as I bought a pair of these. So we will see how well they are with returns. Anyways these 12 inch subwoofers are the best bang for your buck i can find anywhere so dont hesitate to purchase especially from vminnovations they ship quick.

ived used alot of these subs and they work great!!! love them!

i installed 2 of these subs in a 2007 maxima ,with a Power Acoustik Staxe 1250watt 2ch and dat shit whaams hard! ,the gain aint even half way and no lights dimming(10farad cap).

great product fast shipping will order again!!!!  hifonics shakes my durango windows hard for that price....cant beat this deal!!!! thanks.

subs work perfect just dont give them 300 rms max at 250 rms to be on the safe side.

this subs are good for the price but DO NOT OVER POWER THEM had them at 1ohm on my soundstream pca 2000d only lasted for a few hours they do not hit the lows good as i expected but for the price u can beat them
