【BLAM L165A Separate 2-Way Speakers｜Enjoy the Expression of Vocals and Instruments with OEM Replacement】

To the sound of your OEM speakers,

“Vocals feel a little too far away”
“High frequencies are harsh, or they don’t feel quite enough”
“Even when I listen to music, it sounds overall flat”

If you’re experiencing complaints like these, BLAM L165A is an easy-to-consider separate 2-way speaker.

This model is designed less to simply make the volume louder, and more to naturally bring out the presence of the vocals and the fine details of instruments—aiming for a sound that makes the songs you already listen to feel a bit more familiar and close. The midrange has a clear core, and while the treble delivers fine detail, it also has the impression of being easier to shape toward directions that are comfortable for long listening inside the car.

Another strong point of the L165A is that it’s enjoyable without being overly selective about genres—from the atmosphere of classical and jazz, to the punch of rock, to vocal performances in pop. It’s well suited for those who want to clearly feel the change in sound when replacing OEM speakers.

Designed to support sound tuning beyond a simple OEM replacement

The L165A is a separate 2-way type that configures the woofer and tweeter separately. By splitting and reproducing the frequency ranges, it becomes easier to organize the treble near the dashboard and the mid-bass/lower midrange on the door side.

It also supports bi-amp connection. Depending on the vehicle’s system and the configuration of the added amplifier and DSP, the woofer and tweeter can be controlled individually—making it a solid foundation that’s also easy to use for those who want to fine-tune the sound in the future.

With a mounting depth of 71.2 mm, it’s a dimension that’s relatively easy to consider. However, whether it can be installed as-is and what modifications may be required will vary depending on the door structure of the vehicle model, the shape of the OEM speaker, and the available mounting space. It’s important not to judge by numbers alone, but to confirm the vehicle first.

Speaker impression changes with installation and adjustment

Even with the same BLAM L165A, the cohesiveness of the sound changes depending on the door-side base and mounting method, measures against unnecessary vibration, wiring treatment, the tweeter’s orientation, and the final adjustments.

While it’s possible that replacing only the speakers will change the sound, if you want to hear vocals naturally in the cabin or want to align the connection with the bass, it’s less likely you’ll regret it if you consider the installation approach as well.

At Logon, we work with you to figure out how to combine the L165A by checking your vehicle model, your current OEM audio, the music you usually listen to, and the direction of sound you’re looking for.

“I want to be able to listen more comfortably than with the OEM setup first.”
“I’d like to add a DSP and an amplifier someday.”
“I want to know how much the sound will change with speaker replacement alone.”

Even at stages like these, it’s fine. Since the suitable installation method and combinations vary by vehicle, let’s avoid deciding solely based on the product and instead organize the direction while looking at the actual vehicle and how you’ll use it.
