Alpine 12's vs Eclipse Alum 12's

Dude, aluminum all the way. You say you want to play this thing long and loud! The Eclipse is available in either single 4 ohm or dual 4ohm so you have a huge choice of amps available to you. What $ do you want to spend on the amp? Why aluminum?

Because heat is what kills subwoofers, not distortion. A speaker reproduces distrotion when we feed it distortion. A by product of all power usage is heat. Hold onto a light bulb and tell me how hot that 100w bulb gets after 1 minute, actually don't you'll burn yourself, I think you get the point. Anyways the Eclipse has an aluminum voicecoil former thermally bonded to the aluminum cone and two really fat magnets. Expect the magnets to get really warm (they are supposed to) and expect the cone to get warmer. This means that this excellent sub is doing it's job which is why it won an Autosound Grand Prix award for Design And Excellence in Engineering. You can't go wrong with this thing. Put it into a 1.12 cu ft. sealed enclosure made out of 3/4 or 1" mdf. Screw the damn box together or use a truckload of really good wood glue and brad nails. If you can double up the baffle boeard do it as I have seem many an Aluminum sub rip right out of 3/4" mdf. Silicone all inside edges of your box and paint (yes paint) the inside of the box. MDF is extremely porous and bleeds air big time, the paint will help to seal it. Finally add a product like bassline to all walls of the box except the baffle board. If you can make yuor box with at least 1 angle on it this angle coupoed with bassline wil help cancel standing waves. It LBS. dude. Add 1 Audio Contol Epicenter and you should get bass that will shake you like a bowl of jello in an earthquake. If you can tell me if your going with the single or dual dvc sub then I'll point you in the right direction for an amp.
