Good subwoofer, for the price you just can't beat it. Bought one to put in a custom sealed enclosure and plan on using it as a home theatre subwoofer. I wired it to 8 ohms, because my Sony receiver is not 2-ohm stable (it's only stable down to 4). Wired this way it's only going to be getting around 75 watts, but it certainly puts those watts to use. This thing moves well! Great excursion. Sound quality is really good, something I didn't expect at this price. I'm going to leave the plastic piece on the back because it was well secured and didn't rattle or make any noises for me, which was a huge plus. It's a gorgeous cone, and I think this subwoofer will be enjoyed for a long time in my living room. (ALSO: This speaker says it is 400RMS but it is not designed to handle that much power constantly. I would not put over 250 watts on one of these, it's just not made to handle any more.)

I purchased this subwoofer along with an Atrend 12' ported box a little over a week ago, and wow I must say what a nice little combo. This subwoofer is perfect for people on a budget, or for a starter subwoofer. You could even use it if something were to happen to your current subwoofer until you get a higher end replacement like me. I didnt really have high expectations, but I am plesantly surprised to say that this little guy hits pretty hard. As long as you tune your amplifier and your equalizer settings on your stereo correctly it will sound really solid. It took me about 20 minutes to figure out the right amount of bass, treble, etc to apply to the settings. I keep my amp turned up only halfway on the bass settings, and do the rest on the stereo. I have this paired to a Hifonics 1200 watt super class D mono amp and it sounds great. This hits smoother but not quite as hard than my previous Audiobahn which was 900 watt rms, 1800 watt max. Once again if your looking for a quality budget sub, and you tune it right you will be happy. If i don t get the Alpine Type R next, I will be getting the next tier up of the Hifonics its only 65 bucks and pumps out a few hundred more watts.

My sub came all scratched up logo paint chipped haven’t tested them yet so I don’t know If they work((update))speakers were blown the customer service wasn’t really helpful but good price for the subs I’d just save the time and spend extra on their other subs or a different brand

I bought this exact Hifonics HFX12D4 12" sub from an audio store here in Las Vegas. This guy has a little shop setup in a store called "Savers". He had all kinds of car stuff, such as subwoofers, amps, various gauges of wiring, etc. My wife and I were there about a month ago shopping for her first sub. We tested 4 different brands(Sony XPlod, Pioneer, Kenwood and a Kicker) all of which were 12" speakers. They all sounded great. I mean they sounded really good. Then one box design caught my eye, and the price was right so I told the guy to hook it up. It had this 12" Hifonics sub inside. He hooked it up and played a song and immediately I knew this sub was the one. The bass was so natural, I mean it hit the lows so perfectly. The deep bass notes breathed like a beast hot and heavy like some sort of mythical dragon. The punchy bass notes were always on time, CLEAN and CLEAR! It's hit every high-low bass note really well. I don't know why some other reviewers say that it hits those notes bad. Maybe it's a matter of musical taste which makes the sub perform differently. I listen to all sorts of music, even Japanese music and I hear all bass notes just fine. I sometimes have to reduce the bass on my head unit because it literally doesn't miss a note but back to the store...... It's like, the louder he turned it up, the better the speaker sounded, it was just sickeningly orgasmic so I bought it right then and there for $100(ported box included). She has it in her Ford Explorer and she likes listening to loud music of all genres and whenever she's pulling up in the driveway, you know it's her because the windows shake. SooooOOOOOo. I went back to this same place 2 weeks ago after blowing this cheap 400W old Pioneer sub(it was smoking and everything. I had to pull over because I thought something was on fire). It just so happened he got another Hifonics sub(HFX12D4), that was a 12" also. I bought that one for $100(ported box included). Now, my wife and I both have Ford Explorers, with Crunch 800W amps, and 4 Polk DB571 Door Speakers with Sony 660UP dash receivers so everything's pretty much identical in our vehicles. I recommend this stereo receiver as well because you can personally tune just about every setting(EQ, HPF,LPF,Subwoofer Level,ALO, DM+, Loudness, and a bunch of other sound options to get your music sounding just right). Our subwoofer box designs are a little different, both ported, but we still get a bunch of head turns when we're out driving. I was just out tonight cruising down The Strip with my radio turned up halfway(25); and people on both sides of the Strip stopped doing what they were doing turned towards the street to see where the music was coming from. I've had people at stop lights literally roll their windows up next to me because the music was so loud. I get at least one compliment a day from people watching me approach them as I'm driving down the street. Some people will waive their hands at me, some will start dancing along with the music, some will just stare. Now I'm not saying this is the best sub in the world; there could be better sounding ones out there but from my own personal experience with this sub, having just ONE, ONLY ONE in my car with the equipment that I have(which isn't even that powerful), this is probably better than anything you'll find out there, and for the price...man. Get these subs while you can! You will NOT be disappointed in the amount of power you can drive into these things and they'll still sound flawless. They're lightweight and hit harder than you'll ever know. Trunks will rattle, mirrors will vibrate, you will wonder why you haven't gotten one of these sooner.I am ordering another one as we speak. One is way more than I could ever have anticipated, way more than enough. I just want to see how two would sound.

At first I hooked them up as replacements for some 12 inch Phoenix Gold that were over 10 years old and finally giving out. So through comparison had high expectations and I was thinking that they would be at least decent. Unfortunately upon installation even with break in period , I was disappointed and couldn't even believe the sound I was getting out of them. I've had a set of hifonics before and was pleased with them but these ones really just disgusted me. On verge of returning, then I checked amp settings and disabled the sub sonic frequency and changed from 30 hz to between 120hz -150hz and got rid of the popping sound then I decided to change from a ported box to a sealed enclosure and damn my bass came back , like it was a different set of subs were installed. Now that's the way I was used to hearing my stereo. . Glad I didn't send back. Recommend them to anyone who can utilize a sealed enclosure. . With ported box sounds like crap , sealed box sounds great 👍
