## Description

Alpine SWT-12S4 Bass Reflex Subwoofer Tube, Multicolor

Review: Five Stars - Awesome, Little Bigger for a SUV , but performance is mind blowing
Review: A performant beast - I had bought this woofer back in 2016 for the puny boot of my dzire lol! Although It takes up 3/4th of my boot space, I can still fit some luggage. For longer drives unfortunately I always need to remove it temporarily. But I have enjoyed every little bit of this beast on music varying from metal to electronic to classic rock to bollywood. At times it puts out power that my boot can't handle and it rattles the whole car, but the woofer stays effortless! I have never had opportunity to push it to it's limits. There is a composed bass even at low volumes, but at very low volumes, reproduction suffers, but that could be coz of the amp. The bass will not boom, even in a bigger car. Make sure that you have set the crossover to your taste, else you might not enjoy some extraneous frequencies, or if you don't like higher base much like me! Rest assured, the reproduction is very tight and controlled. Thanks Alpine for such a masterpiece.

### ⭐ Not Original.
*by M***V on 14 September 2017*

I ordered this product on August 24th and got it delivered on September 5th. This product claims to be Alpine but my technician informed me that this is a replica or a look alike of the original brand. Alpine sound systems sound really good but not this one which I got. I verified with the Alpine company's websites and it shows that the model SWT-12S4 has a peak power of 1500 Watts but this particular one's peak power is shown as 1000 Watts on Amazon site - which is a clear indication that this is not original. And above all, I have listened to it - it functions really bad. I fitted this in my brand new Brio - and the sound is pathetic.
