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.

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.

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

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

Excellent sound quality. Very accurate bass.

Very good s.q and good so I. Strong sub. Alpine is legendary even if they have fallen off some since the early 2000s
