## Overview

The Alphasonik AS12DF is a 12-inch, 1500-watt max down-firing subwoofer designed for tight vehicle spaces. Featuring a slim 6.7-inch depth and an air-tight MDF enclosure, it delivers deep, rich bass with minimal vibration. Its spun aluminum cone and copper-wound voice coil ensure durability and clear sound, while the versatile mounting options let you install it vertically or horizontally. Ideal for car and truck audio upgrades where space is premium but powerful bass is non-negotiable.

## Description

By installing the subwoofer downward, the AS down-firing enclosures` optimize bass response with superior efficiency for richer, deeper, heart pounding low frequency sounds regardless of the enclosure installed position. The sleek design of the AS enclosures allows for installation anywhere in the vehicle, they can be installed vertically or horizontally. The durable MDF wood construction is designed to reduce vibration. Additionally, a special bonding sealer is used to create an air-tight seal to increase joint strength as well as bass reflex. The spun aluminum cone stays rigid even with the most powerful bass notes. Alphasonik's compact down-firing enclosures perform superbly, producing extreme bass with minimal space.

Review: Great results from a slim sub - I waited a year to write this review in order to be fair in my assessment and to also be able to speak to the durability of the product. I installed this sub in a Jeep Wrangler and powered it with a Rockford 5-channel amp that is also powering four 6.5s. I didn't want to take up a lot of space in the cargo area with a huge box and I really just wanted to round out the low end; I listen to a lot of classic rock and reggae so I was not looking to shake any windows since only about 10% of what I play falls within the rap or hip-hop genres. Initially, I was pretty underwhelmed with this sub - the first couple weeks gave me average performance at best and I did also experiment with some bass-heavy R&B just to see how it would perform. With the R&B, it produced a dull thud-like sound and with the classic rock, it really didn't sound very good when turned up loud enough to make a difference. But over the next month or so, it started to loosen up and sound more musical than noisy, and after about 3 months of moderate use, I became very happy with it. Again, I was not looking for club-quality bass, I just wanted to add some depth. That being said, it also performs very well now when I pop in some rap or hip-hop. Not a competition sub by any means, but I find myself needing to turn down the bass level for these genres. When the doors and top are off the Jeep, I'll adjust the bass knob a little higher and it is sounds great, even above the wind noise. My bottom line with this sub is that it is an excellent choice for anyone who wants to add nice tone to the lower end of the spectrum. It takes up a surprisingly small amount of space for a 10-inch, and i feel it is a bargain at this price point. The construction of the box itself is also very solid; it's had sports equipment, lawn supplies and such thrown on it, placed on it, been covered with it and a year later, it's no worse off than the day I got it. If you give it time to work itself in, you'll be happy.
Review: Decent bass response! - Was able to fit this under the drivers seat of my 2016 Wrangler with a little bit of ingenuity. Sounds great for the price.

### ⭐⭐⭐⭐⭐ Looks and sounds great!
*by D***S on October 31, 2025*

It was easy to connect, my car was prewired from a previous system, yet it went smoothly and sounds great, the low profile is perfect for my jeep and makes loading supplies much easier.
