Well made enclosure

This enclosure is well made. Very sturdy and the carpeting is nice. The only problem with this product was the terminals. They worked themselves loose and were arching causing the plastic to melt.

overall good enclosure

I got this box for my alpine type r and it was pretty for $20, I filled the box with polyfill and it hit. I think if you need a cheap box for your system this is the was to go.

heavy solid box...

at first i was skeptical about ordering this box because it was so cheap...u know the saying?"u get what u pay for"?well i bought this cheap but the box was built solid...but then again it was the sale price not the regular price-so u can look at it as pricey box for less...i got this box to house my single 12" dvc alpine type r woofer-and it hits clean bass but then it also helps to have a sub like the alpine type r...all in all im very satisfied i bought this box-it was way cheaper than buying it from my local in door swat-meat type audio store -they wanted 65 bux for a prefab sealed 12" box!!!they str8 scamming(in my opinion)...this was the cheapest store online i found for boxes among other things...

its good

this box works great for smaller subs but if you want to put a larger more powerful one in it you are also going to need a bigger box

solid box.

I BOUGHT THIS BOX ABOUT A YEAR AGO AND I HAD NO PROBLEMS WITH IT, I JUST FILLED IT UP WITH POLYFILL AND IT GETS THE JOB DONE. I HAVE A P2 AND IT HITS GREAT. RECOMEND THIS BOX TO ANYONE WHO WANTS A CHEAP BOX THAT WILL LAST.
