Alpine X-W12D4 with Ported Enclosure

Great for small cars

I bought this box for my soundqubed 12". It was the smallest box I could find that fit a 7" deep sub. Works great. Hits pretty hard with the sub. The inside is sealed well, which is hard to find for a prefab box.

Decent

Arrived dented in the corner and it seems the cut out for the sub is slightly too large. It was for my alpine type r.

Nice Box

This is a nice box. You're not going to get a ton of thump out of this box. It just isn't going to happen. I have a dayton HO 12 in it and it puts out good base with a ton of musicality. It's more of a sound quality setup. No complaints here.

Good box

Has seen three different subs and awaiting a fourth. One spot is starting to split from the screws but other then that it's great. I stuffed it with poly fill

Top of the line

This beauty makes massive sound. It pours massive bass into my car. Custom box tuned to 34hz lets this sucker hit like a 15". The low to midrange bass it produces sounds phenominal! The bass is worth the price no doubt.

Impressive

So I'm new to Alpine subs, in my youth I ran kicker and the occasional JL audio, as I got older I ran Rockford fosgate if I wanted to get loud but generally went back to JL. This time I wanted loud with clarity and quality but the JL w7 and many times the w6 is just too much money. So I got a 10" type x, and built a box the exact spec.s, and pushed it and a TW3 with 1200w RMS (2400 PEAK) and liked it so much I just purchased a 12" type x, and even in a prefab box the two type Xs are loud, low, and produce some of the best bass I've ever heard.

NOT A RELATABLE SUBWOOFER

This subwoofer has an aluminum heat sink that came loose and shot out of the dust cap and with the speaker grill holding it inside, destroyed the paper cone, coil and spyder are still in tacked. And just 18 days after the warranty ran out. The amp I ordered is still within the year of purchase so I know this subwoofer didn't make it past a year. The amplifier used was an Alpine X-A90M with the gain set with an SMD DDM

Small pro box love it

Great sub

I have had many type R 12 and this time was running a bigger amp so needed something that would handle the power so I am running each sub off a pdx-m12 on each one and they sound amazing and hit hard
