I tired out 2 12' Alpine type R's in my car for about a week and they were VERY punchy and sounded quite good.
When theyw ere in my car they were crossed over at 85hz lowpass with a 24 db slope.
Try that out and I am sure you will get good results from those subs.

very interesting observation, what 12" subwoofers did you use that sounded sloppy and if xover was the key we would all get our woofers at radio shack

Once the x-over point has been raised, I would look at the enclosure. You shouldn't have to go ported. Sealed boxes can have a fair bit of impact. I would agree with what was said above, try to reduce the box volume a bit, and see if it makes a difference.

What is your x-over currently set to?

Another thought: How are your subs positioned in your car? (facing the rear, front etc?) Sometimes changing the orientation/position of the subs can make a world of difference. Also, what vehicle is this in?

It would seem that the Type R's like a smaller sealed box than you would expect, I had a 10" Type R in .75 cubic feet before, it seemed too big for it, as it was quite boomy, and not very punchy.

Are these the 1241D's ? If so, I ran them through BassBox, it suggested around .7 cubes per sub for a fairly flat response, that is in a box with lots of polyfill.

If you want your woofers to sound punchier then you should be concentrating on your midbass speakers.... [img]graemlins/thumb.gif[/img]

I was able to get them sounding pretty good. I actually lowered my crossover on the amp to about 75Hz (24db/octave) so I can still play with the 12db/octave xover on my indash EQ to different music. I am using a little bit of boost around the 50Hz mark. (I've got a parametric EQ on the sub (40-60Hz) This all done it sounds really good on classic rock, (floyd and stuff). and on the newer music I have just determined that it is all sh*t and I should just listen to classic rock only and rap when I wanna look cool for the ladies (j/k). My subs are rear facing in my 98 prelude in a 2 cube (common chamber) prefab box that I siliconed and stuffed a little. With the speaker displacement that only .84 per woofer. Could the common chamber be the problem?
Thanks guys
