[L-165RS | 16.5 cm woofer unit with an AM diaphragm]

I’d like a bit more depth in the low end of the factory speakers. But I don’t want to add a large subwoofer and make the cabin feel cramped.

For people like that, consider the L-165RS, which incorporates the design philosophy of BEWITH’s Reference AM series.

Despite being a 16.5 cm woofer unit, it uses a long-stroke suspension system and an upgraded magnetic circuit. It doesn’t just increase the amount of bass—this unit supports your music solidly, including the sound’s attack and the amount of information.

How the sound changes inside the car with the L-165RS

The cone uses an aluminum–magnesium alloy diaphragm with low weight, high rigidity, and moderate damping.

This is a speaker that plays low frequencies, but it isn’t the kind where only the bass stands out strongly. Designed with an emphasis on integration with vocals and the mid-to-high range, it adds thickness to the overall sound while making it less likely for fine details to be lost.

Long-stroke performance achieved via a large roll edge and a large center cap expands the expressiveness of the low end even in the 16.5 cm class.

When you listen to your usual music, you’re likely to notice changes such as:

• The presence of the bass and kick becomes naturally stronger
• The sound’s foundation stabilizes, and the overall presentation gains thickness
• Even at low volume, musical information is less likely to get lost
• It becomes easier to consider a configuration that doesn’t use a subwoofer

Sound pressure performance is improved by 3 dB over the previous model. It’s tuned not only to deliver a greater sense of energy when you turn it up, but also to help you feel the core of the music even at your normal listening volume.

A woofer that fits both 2-way and 3-way setups

The L-165RS is a woofer unit that’s easy to use in both 2-way and 3-way configurations.

However, simply swapping speakers won’t result in the same kind of sound. Depending on the combination with a tweeter and midrange, the installation condition on the door, how the baffle is made, and the approach to vibration damping and sound absorption, the way bass comes out and how well it connects with the mid-to-high range will change.

If it were me, I wouldn’t judge only by the L-165RS’s standalone performance. I’d look at your current system as a whole and plan the best combination.

Will you use the factory navigation, or add an external amplifier? Will you use a subwoofer, or will you consolidate the low end thoroughly from the front? Depending on the vehicle model and how you listen, the “best” setup will differ.

Bring out the best of the L-165RS—down to the installation method

Because it’s a 16.5 cm size, it’s a woofer unit that’s easy to consider for a wide range of vehicle models. But for real installations, you need to confirm details for each vehicle.

If you replace it without checking things like the depth of the door and potential interference with nearby parts, the condition of the mounting surface, and differences from the factory speakers, you may not be able to fully take advantage of its performance.

At LOGON, we don’t stop at “installing the speakers.” We guide you by considering the vehicle’s condition and your intended use, and by thinking through the installation method and the overall system balance.

For those who want more bass, the direction you choose will change depending on whether you simply want more quantity, or you want a low end that strongly supports the entire music.

Will the L-165RS suit your current car? Is a combination with a subwoofer a good idea? And how much change can you aim for from the factory system? Let’s not decide only the product first—while we confirm your vehicle and the music you usually listen to, we’ll organize the best direction together.
