【MOREL PRIMO 104 | 10-inch, 4Ω Subwoofer】

I want a bit more low-end thickness and a sense of scale in the sound from the factory audio. However, I don’t want a subwoofer that just plays loudly. If that’s what you’re looking for, the one to consider is the MOREL PRIMO 104.

With a 10-inch (25cm) cone and a rated input of 300W RMS, this model not only adds a fuller quantity of bass, but also makes it easier to give the entire music mix more depth—from the presence of bass and kick drums to the atmosphere in movies and live recordings. Thanks to its ±8mm wide-stroke design, it aims for a cohesive low end that won’t push too far forward while still moving the lower frequencies with authority.

Built with a high-stiffness paper cone, a rubber surround, a 2-inch voice coil, and a ferrite magnet, it supports a frequency response range of 22Hz to 900Hz. Since it works with both sealed boxes and vented (bass-reflex) boxes, it’s also easier to choose an enclosure based on the space available in the cabin and the direction of bass you’re after.

A subwoofer isn’t a component you can simply finish by installing the unit. Unless you get the box volume, mounting method, combination with the amplifier, and the integration with the front speakers right, you may end up with bass that’s overly noticeable on its own. If it were me, I’d first check things like “how much do I want to increase the bass?”, “what kind of music do I usually listen to?”, and “how much of the cargo area do I want to use?”, and then decide whether the PRIMO 104 is a good fit.

At LOGON, we think through everything together—starting from selecting the subwoofer, then the box, amplifier, installation, and sound tuning—based on your vehicle model, your existing audio setup, and how you plan to use it. If you want to hear your usual songs a little deeper and more enjoyably, tell us your vehicle specs and your preferences. We’ll propose a setup that doesn’t force huge bass, but instead aims for a natural blend with the front speakers.
