According to alpines webpage the ten inch r1 has an ideal sealed box volume of .75ft cubed. The zenclosure is .8 ft cubed so im confused to why that is too small.

 

Subwoofer displacement.

 

alpine makes a new ten that would clear the seven inch depth of the zen. the new alpine is almost two inches less deep i think. is that what you meant by subwoofer displacement?

 

Yeah

Motor is still big, though. You can put it in that box if you want to, but it will fall flat on it's face around 40hz. You'll probably be down 20db in output around 30hz in a box that small.

You can have a small box, efficiency, or low end.

Pick 2.

 

does the type s have a smaller motor?

 

Yes, but it sucks.

 

This is more complicated than i thought lol. So losing 20 db is alot?

Driver displacement is .08 cu. ft. I personally would run a larger enclosure than what their manual lists as ideal, you will get better extension and most importantly with acoustic suspension designs: a lower system Qtc than .9 (it will sound better). .8 cu. ft. will do well.

.4 dd... no, it would take 3 12W7's to clear that figure Details, details...

 

Alpine is usually spot on with box requirements. JL and kicker are always off.

 

I know db is a log scale so wouldnt 20db less be 1/2 as loud? Its been awhile since my last physics class lol. Eggyhustles, would the daytona sub you recommended work well in the zen. Sorry i want to get this right. Thanks for all the replies

 

10db is twice as loud to the human ear.

And no, the dayton was designed for small vented.

This would work well

Now what if i went with the single twelve inch zen. Any recomendations. Type r too big for that too? Thanks.

 

It'll work

any reason why you're stuck on alpine?

 

Not really besides the whole brand name thing.

 

So you're buying because of name rather than performance?
