Genetically Built Like A Type-R

The new Type-E’s highly efficient design can play both louder and lower, and is more durable than its predecessor. With a shallow mounting depth, these subs can be installed just about anywhere, but they look so good, you won't want to hide them.

The Type-E cones are built with a reinforced parabolic cone structure and lightweight poly mica dust cap, enabling a faster snappy dynamic response. The high excursion Santoprene® H.A.M.R. surround allows for impressive linear excursion so Type-E subs play louder, and lower!

What is unique and amazing about the new Type-E subwoofer is not only the engineering behind the build, it's the new requirements for them to optimally perform. The new Type-E 12” specification requires 0.65 – 1.0 cubic feet air space for superior performance. That’s 35% less air space used in your vehicle!

Great sub for the price

The following review is for a previous version (SWE-1243).

You simply can't beat this sub for the price. I'm powering it with a little Rockford Fosgate 150-2 amp and it hits hard. I run it at half the power I was with my other setup (12" Apline Type-S and some cheap Power Acoustik amp) and it hits harder than the old setup ever did. Pair this sub up with a nice quality amp and it will produce some awesome bass that hits hard and still sounds clear for a fraction of the cost of the higher end stuff.

PUMP UP THE BASS!!!

The following review is for a previous version (SWE-1243).

YEAH BOY! Two of these in a custom ported box and damage was done.... Cracked my windshield from the reflex, my mirror broke (wouldn't stay in one position always tilting down) and it fell off. My meter reads at about 550 watts max per sub at close to full volume on the speakers. I get looks from everyone when I turn these BAD BOYS UP! Alpine is the way to go. Get some today. Make it 2 or 3 or 4...... either way these subs KICK OUT THE JAMS!

Alpine Type E

The following review is for a previous version (SWE-1243).

For the price of the sub, its a good buy. I would recommend to buy two of them, it sounds so much better. but the con of buying them is that they seem fragile so don't push it with them.

bumptastic

The following review is for a previous version (SWE-1243).

My friend has two of these hooked up to a crunch amp. They hit pretty hard, and the clarity is amazing. a guy i know has 4 type r alpines, and they make his back windshield flex. alpine is the way to go, no doubt.

Very Clean

The following review is for a previous version (SWE-1243).

This sub is great. Definitely worth the price. It kicks out nothing but clean solid bass. Mine is in a 2 cubic ft custom ported box I built myself and it sounds so good. It is cleaner than JL. I really like how it comes with the grill too, it adds a smooth look to it. The best part about this sub is the cone composition. Very strong and very cool look. One of the best looking subs around in my opinion. Buy it and you won't be disappointed.

Wow! This is better than I expected!

The following review is for a previous version (SWE-1243).

I have one of these with a 300 watt alpine amp and this thing bumps. I don't have it turned up all the way and my mirror shakes, rattles my trunk and people hear me coming. It's great with all types of music and alpine is the best you can get!
