Overview
This MartinLogan speaker combines surround sound and woofer duty in a single 5.25 inch coaxial driver, finished in white and built for tabletop placement rather than wall or ceiling mounting. No model number is listed for this ASIN, so match it by these specs and the product image before ordering.
A coaxial driver places the tweeter and woofer on the same axis, a design aimed at consistent sound imaging from a single point rather than spread across separate drivers. Being listed for both surround and woofer roles suggests it's meant as a flexible channel speaker rather than a dedicated front or center unit. The coaxial connector is worth noting since it differs from the HDMI or optical inputs common on newer AV gear.
- 5.25-inch coaxial driver
- Surround sound and woofer roles
- White finish
- 18 lb tabletop speaker
Who it's for
Fits buyers wanting a compact white speaker that sits on furniture rather than mounts to a wall, filling a surround or bass-support role. Less suited to anyone who needs a specific MartinLogan model confirmed by number.
Pros and cons
- Coaxial driver covers surround and woofer duty
- White finish for light-colored rooms
- Tabletop mount needs no wall hardware
- No model number listed for this ASIN
- Coaxial connector differs from HDMI or optical inputs
- No power or frequency spec provided
Performance notes
The coaxial driver layout is designed to handle both surround and woofer duty from one unit, and tabletop mounting means no wall hardware or bracket is needed to set it up.
