Perfect Starter System

The MTX TNE212D is an ideal solution for anyone looking to add bass to their vehicle's system without breaking their bank or going over the top. The TNE212D is the perfect combination of performance and value ensuring that enthusiasts of all types can enjoy the hard hitting bass that MTX has built its reputation on for 40 years.

Unbeatable Bass and Unmatched Performance

The MTX TNE212D combines great subwoofer design with perfect enclosure design to deliver bass that far exceeds expectations. The unit is a dual 12" sealed enclosure that has a single terminal cup showing a final 2Ω load to any connected amplifier. The Terminator subwoofers used in the enclosure include polypropylene dustcaps that are durable allowing them to survive the rigors of most trunks and are lightweight allowing them to efficiently move using less power. Each subwoofer can handle 200 watts RMS power, resulting in a power level of 400 watts RMS for the entire enclosure. The subwoofers also incorporate Spider Plateau Venting, which is a mechanical cooling process that allows the subwoofer to continually refresh the air around the voice coil helping to dissipate the heat generated during extended play. The enclosure itself is made using extra-strength 5/8" MDF (medium density fiberboard) which is the preferred material for subwoofer enclosures. Where other manufacturers only use a 1/2" board, the MTX 5/8" board is stronger ensuring that the enclosure can contain the massive low frequency sound waves generated by the subwoofers without problems.

Classic Look and Contemporary Style

The enclosure is wrapped in black aircraft grade carpet. The classic black goes well with any interior and the high quality ensures it will be resilient to tearing and wear. The embroidered Terminator logo and large MTX Audio logos on the dustcaps ensure that everyone will know what brand you choose to ride with when you open your trunk. Just remember not to tell them how much you paid if your system is louder than theirs.

This was a great buy for the price. but you have to buy a better amp then the 600-1200 they send. they do put out the power they say but with battery cable size power and ground the amp shuts off due to overheating after about 30 min. i drive a long way and that's why i wanted this. for the price go with the little bit better subs without the amp and order an amp with a fan. I rate it 5 without the amp and the amp is great for 30 min then you have to shut it off or pull the fuze and let it cool down. So i would rate the amp a 2 that's for both the amps they sell the 250 which is a 600 and the 1200 they sell are both useless to me

ORIGINAL REVIEW 7/28/2014

I have only had these installed for 2 days now but all I can say is: I LOVE IT! I paired this with the Boss Audio 1100-watts Monoblock amp, wired with the 8 gauge Boss Audio amp wiring kit & it works great! These subs kick HARD! I love it! I have them in the trunk of my 1995 Honda Accord Ex facing the trunk opening and the sound quality is superb! I have friends with Rockford Fosgate subs and these sound just as good, if not better for 1/3 of the price!

UPDATE 3/3/2015

Still kicking hard! I tweaked the settings on my deck (Pioneer AVH-X1600DVD), and now my subs sound & feel much better than when I first installed them! My bumper does rattle, but then again, I am driving a 95' Honda Accord. My license plate was even worse until I stuffed some foam behind it to quite it down. I added a video to this review today too so that everyone can see just how great these subs are even after roughly 6 months of kicking at full volume every single day!

What I am using with these subs (for quick reference):

BOSS Audio R1100M Riot 1100-watts Monoblock Class A/B 1 Channel 2-8 Ohm Stable Amplifier with Remote Subwoofer Level Control

These subwoofers are incredible and will offer more bass than you will ever need. I bought these with the boss 1100 watt amp and they hit unbelievably hard. I'm honestly surprised they are even this cheap as I would have payed double this price for how they sound. If you're on the fence about these, I can assure you these are the way to go. Plus, the build quality is great and looks really clean. You can't find subs like these for this price, especially when they are already in a factory sealed enclosure.

UPDATE: I don't normally do updates, or even reviews for that matter, but I felt like I needed to after using these for over 6 months now. This is because my terminators are by far the best $150 I have ever spent. I absolutely love heavy bass and these went above and beyond both my expectations, and wants, for bass. I did notice that I have slightly increased the bass level of my casual listening over time, and I'm only barely above half way on the amp setting (which is overwhelming for anybody who rides with me).

I did want to clarify a little as to how they sound. Please note that these sound very VERY deep. I say this because, while they do hit hard, and even very hard in certain situations, the majority of your listening will have a very low, smooth bass pattern. You can obviously adjust this in your tuners frequency settings, but they will have this low and deep sound more often than not. To me, this style has always struck me as a richer, more professional sound (yes I know these are far from professional speakers), but I still think this style sounds "nicer," so to speak, than subs that simply punch you in the face.

Seriously a great deal for Subwoofers! The first day I got them I hooked them up to my amp and wow! They pack a punch! For the price, I'm quite pleased. They shake my mirror like no tomorrow. Would recommend for anyone who is looking for great bass on a lower budget!

I'm a certified installer from back in the day. My past rarely allows me to settle on mediocre sound in my vehicles. Bass in a system is the filler that adds depth and dimension to your sound. I made the decision to run a larger than needed sub box to sound good at low volume (doesn't need to struggle) and because I have the room in my old beater van. Plus because this is in my beater I didn't want to spend much but ended up with way more than expected. I remember needing my customers to spend at least $1500 for a total system to get the sound this has.

This MTX terminator sounds perfect. I went with this mainly because it is a sealed box. Sealed enclosures tend to work with all music types. Not too boomy or muddy. Band pass and sealed have been my favorites.

Teaming a heavy duty enclosure with a quality amp is a must. I went with the Rockford Fosgate R500X1D. Good amps are always underrated. The Rockford Fosgate R500X1D is rated at 500 watts into 2 ohm but registered at 631 watts! Proper wiring is must. I used 4 gauge high quality power cable. Be careful with wiring these days, many companies lie about wire size. They say 4 gauge but you end up with 6 gauge wire with a 4 gauge jacket. Go with a good brand and expect to pay good money. It will be worth it. Also notice in the picture, I added 4 gauge quick connect for power and ground so I can quickly remove the box if I need extra room for moving items.

The team is a perfect match. Playing the police to slipknot sounds unreal. Very smooth controlled low end with a good punch you can feel. No noticeable coloration or distortion.

You will love this enclosure for sure.
