sow/n\low beat me to it, the Alpines must be good they were in all those 12 sec cars in the Fast and the Furious

The Alpine woofers are pure marketing, sure they go loud and sound reasonably decent. But anyone with a decent ear will hopefully see that they acually sound like Pooh.

When someone thinks they sound good it scares me lots!!! [img]tongue.gif[/img]

But at least you can say "I have a TYPE R in my trunk wewwwwwwweeeee!"

Doesnt that sound good "TYPE R" "TYPE R" "TYPE R"

Hmmm what to call the new woofer, hey I know lets call it TYPE X [img]graemlins/puke.gif[/img]

 

It took a lot of patience and Time, with a lot of inspiration coming from slingshot on this forum

 

At the local Circuit City, the type R was mounted in an identical box as a pair of polk momos and some sony X-plodes. It was an interesting coparison, I personally liked the MoMos the best in that group, but the Alpines sounded different from every other sub on the board (different tone). I dont want to trash them because they appear to be well made but I am not sure they sonically compete in their price range.
Geeeeeez they have been hyping the type X for how long now....

 

Dukk your right on the button. If you analyse transient of a base note, there is often an initial pulse that happens about 150 - 300Hz. Your mid-bass drivers reproduce that.

The other thing I found (I have 2-10's in a sealed box)is that getting a amp that has 3-6db of base boost. My first amp that had 350 watts produced bass that was ill defined. The drivers lacked that slap. I borrowed a similar powered amp from my son Adam that had the boost and the difference was significant. You can feel that kick. He didn't get it back. He's got to much stuff anyway.

 

I am guessing it wasn't one of the Audisons..

 

The definition of punchy varies so immensley from person to person that asking for advice in solving a problem with it is a huge pain in the ***. From what I'm reading here, people seem to equate a peaky enclosure with being punchy. If you subtract space from your enclosures you will start developing a peak in your response. While this peak can be beneficial in some instances to overcome the naturally high noise floor in a vehicle, if it's too high (read Qtc .8 and up) you might as well just turn up your bass boost (which is essentially an EQ about the 45hz region for most amplifiers). To me, punchy means transient accurate and tonally accurate.

If you're looking for more low end grunt, while maintaining your present SQ (or increasing it slightly) you have a couple options. An increased enclosure size will produce a drier (more transient perfect) sound from your woofer. In such an instance, lower your crossover point to no higher than 60hz. Anything above that your midbass should be handling (which, consequently [mentioned earlier] adds snap to your subbass hits). Your other option, as I see it, is to place your Type R's in a ported enclosure tuned low (25-28hz-ish). You will maintain a good amount of your present SQ while beefing up your lower end impacts, which should keep you satisfied.
