MORE BASS WITHOUT CLARITY IS JUST NOISE.

Our woofers are not only louder, they're cleaner and clearer.

NEARLY FLAT FREQUENCY RESPONSE FOR EXCEPTIONAL LINEARITY

in the key sub / mid-bass frequency range from 40Hz to 200Hz (+ or - 3 dB). Which means "clean" and balanced bass.

SUPER TIGHT, PUNCHY MIDBASS

Your factory underseat woofers aren't just subwoofers; they're midbass drivers. That means they play not just the lowest frequencies, but also "punchy" midbass frequencies like snare drums and high bass guitar notes.

Unlike our woofers, which are designed to outperform the factory woofers for both subwoofer and midbass frequencies, other underseat subwoofer upgrades on the market are only capable of playing sub frequencies, not midbass, so you miss a huge portion of the frequency range.
HOW DO WE DELIVER BASS THAT'S LOUDER, CLEANER, AND TIGHTER WITHOUT CHANGING THE FACTORY AMP?

In a word, efficiency. Every watt of power generated by your amplifier yields about 2x the bass output with our woofers vs factory woofers.

If you're not familiar with the concept of "efficiency" in audio, just use this analogy: with your factory woofers, your amplifier is like a 200hp motor in a 4,000lb Camry. With ours, it’s like the same 200hp motor in a 2,000lb Lotus Elise - twice the performance with the same power.

2X THE OUTPUT

Our woofers are 10 dB+ louder from 20Hz to 60Hz vs factory woofers, resulting in twice the loudness in this critical “sub-bass” range (and over 8x the sonic energy). You won’t just hear the bass; you’ll feel it.
We engineered the Stage One speakers to produce higher quality sound: a wider range and more balanced reproduction of the bass and treble you are currently missing.

That's because, unlike your factory BMW speakers, we use proven audio technology:

woven fiberglass cones

butyl rubber surrounds

silk composite tweeters

These technologies working together, result in speakers that remain distortion free at higher volumes for accurate, natural, beautiful sound. Much louder than your factory speakers.
We engineer our speakers with the same unique size, shape, connectors, impedance, and efficiency as your factory speakers.

That means installation is as simple as unbolting your factory speakers and bolting ours in, and it's totally reversible, too.

No one will ever know you've upgraded your audio system except you. Unless, of course, they hear it.
Simply unbolt, unplug, and remove your factory speakers and plug ours in. It's that simple.

Ever put together IKEA furniture? Then you can install the Stage One Kit.

Each kit includes step-by-step instructions, and is designed to be easy enough that anyone can install it in just a few hours.
Everything we sell has been engineered for durability and longevity, and we know what we sell will last... and last... and last.

That's why our upgrades are backed with our industry leading 4 year limited warranty. So if something breaks, send it back. We'll replace it at no charge.
