2nd Generation Alpine R-Series : Detailed Functional Overview

In this article: We take an in-depth look at Alpine’s award-winning R-Series subwoofers, giving you all the details you need to know to help you understand why this is such a great choice.

Product overview of the Alpine R Series

Alpine updated the R-Series subwoofers for 2022, giving them a refresh and overhaul in several key areas. The R-Series has always been among our top pick car subwoofers, and the next-generation design makes these subwoofers some of the most desirable on the market today. In addition to all the cool technology Alpine uses to deliver deep, clean bass, the new lineup includes a variety of options to help you build the system you want. In our opinion, these are also some of the more affordable subs you’ll find with performance that rivals much more expensive offerings.

Bass cone and surround

Alpine R Series cone design

Alpine found that the best way to make a bulletproof subwoofer was to use bulletproof materials. While the woofer doesn’t stop a bullet, it features a unique Kevlar-reinforced pulp structure. The unique blend of materials makes the woofer cone light and stiff – ideal for reproducing the deepest bass tones that put a lot of strain on the cone. The cone also uses a special polyceramic dust cap that further enhances the rigidity of the cone and eliminates distortion while keeping the motor structure squeaky clean.

Alpine R Series HAMR Surround

The subwoofer surround ensures that the woofer cone moves in a single, straight motion. Conventional half-roll surrounds tend to wrinkle and warp under heavy loads. Alpine’s HAMR design means you get increased excursion from the folded surround design, without the distortion introduced by folding.

Voice coils and motor structure

2nd Generation Alpine R-Series Dual Stack Magnet

The R Series subwoofers are available in two ohm and four ohm dual voice coil (DVC) designs. This means you can easily set up the perfect system, no matter what car amp you run or how you want to wire it. Just make sure the amp/subwoofer combo you choose offers matching ohm specifications, as the difference in resistance between an amp and a subwoofer can lead to damaging results. However, something you don’t see in every subwoofer (even the premium lineups) is an included jumper wiring system, so you can configure the subwoofer appropriately for your system to match your amp.

Another key difference between the previous R-Series and the new next-gen R-Series is a new double-stacked magnet system. The stronger the magnet, the more power and control the motor needs to generate bass. This magnetic structure is both larger and more powerful than the previous model. That means you get cleaner, tighter bass at high volumes.

And with the patented Compound Radius Curve Pole Geometry design, Alpine made this subwoofer a workhorse even when you’re pumping tons of juice. The composite design helps eliminate hot air while creating paths for cooling airflow, ensuring the subwoofer does not overheat.

Progressive reel spider

Alpine R Progressive Spider

One of the less visible but equally important aspects of a subwoofer and its performance is the spider design. Larger excursion speakers require special spider designs that allow the cone to move while preventing the leads from causing distortion and interference. One of the most notable and overlooked aspects of the new R Series subwoofers is the creative way Alpine engineers protect the tinsel cables from damage while ensuring smooth and accurate bass.

Frequently Asked Questions (FAQs)

What is the difference between the new model and its predecessor?

The main difference lies in the dual-stack magnet structure and the advances made in the construction of the surround and woofer cones. The new models are bolder with better bass control than the previous design.

Why are there different options for ohms?

Alpine wanted to cover as many custom applications as possible and the only way to achieve that was to make this series available in three sizes with multiple voice coil and resistor options. When shopping for your subs, you can choose the perfect speaker to complement your amp.

Does the R Series work in small spaces?

The subwoofers of the Alpine R series are intended for compact boxes, but not for outdoor applications. The minimum box size for the 12-inch sub is 0.65 cubic feet, while a sealed box with a capacity of 0.83 cubic feet is ideal.

What Do People Say

It’s hard to find anyone who has anything negative to say about the new Next Generation Alpine R Series subwoofers. Although they haven’t been on the market long, the few people who have written about them say the speakers hit hard and produce clean, clear bass. They come from a long line of respected subwoofers and the 2nd-Gen R series is just an improvement over its predecessors in our opinion.

The Alpine R-Series is one of our favorite subwoofers at the moment because it combines excellent features and technology at a very reasonable price. Having run the previous R-Series – and the Type R before that – we can say this is a huge improvement over what we’ve always thought was an excellent product.
