The Martin Audio A55B 5.25 Inch Passive Two-Way On-Wall Loudspeaker is a two-way passive speaker with an elegant design that is perfect for architectural environments that require high-fidelity sound from an unobtrusive, ultra-compact enclosure. It brings class-leading performance, reliability and value to a wide range of commercial sound applications from retail outlets, bars and restaurants to corporate offices and convention centers.

The A55 is the perfect choice for background and foreground systems which require superior performance. Its Martin Audio signature sound characteristic also provides a seamless sonic transition within a multi-zoned complex using larger Martin Audio systems such as CDD or Blackline X.

Comprising a 5.25” (135mm) LF driver and a 0.75” (19mm) silk-dome HF driver on a 110° x 80° horn, it handles 50W AES, 200W peak and can produce 113dB peak output at 1 meter. It has a smooth frequency response and strong bass reproduction that extends down to 65Hz.

With a nominal impedance of 16 ohms, multiple speakers can be driven in parallel from a single channel of a low impedance amplifier, such as the Martin Audio VIA2004, thereby maximizing efficiency and minimizing cost. For full-bandwidth protection, the low and high-frequency sections are individually protected against overload.

Great product - Add foam product for complete solution
Model: 36 SqFt(3.4 SqM)
Used in two cars with speaker upgrades. Easy to install but get the roller for assured adhesion.removes "tinnyness" from large metal resonators. Use with foam absorptive material for a complete system.

Great Product for noise reduction in Auto Use.
Model: 36 SqFt(3.4 SqM)
I use this on many builds to dampen the metal echo in cars, vans, and trucks. Just one sheet in the center of a body panel is a huge difference maker. You can also cover the entire surface and get added insulation value. The noise is greatly depleted and it's easy to install with a roller tool. Looks Great when done. Good Product I will use again!
