Review: I have had countless subs in my life. Many were from the 90’s era. JL Audio, Rockford Fosgate, older Alpine, etc. I have this single 12 mounted in a sealed 1 cubic foot internal enclosure made from 3/4” MDF. It’s mounted in the lower truck space of my 2024 Tesla Model 3 Performance. It’s powered by an Audison Forza AF-M1D and I am astonished at the sound quality, accuracy and frequency range I’m experiencing. I’ve never had a sub go this low and sound so musical. Every frequency change is so clear. Not boomy. There are frequencies it hits that my factory 17 speaker system has never produced and I couldn’t be happier.
Review: I love the alpine type r 12’s. There an amazing subwoofer. The bass is really nice in a closed box or ported; I prefer the closed for the lows in the bass. These guys are an awesome company to buy your stereo needs with. There quick to help you and message back and forth; a truly pleasant experience. I will buy from this company in the future hands down. If your on the fence making a purchase, don’t be with this company because they have what you want and will take care of you.
