The Martin Audio CDD15B 15 Inch Passive Coaxial Differential Dispersion On-Wall Loudspeaker is a very high-power, passive two-way system designed for installations that demand the ultimate in sonic performance from a single enclosure. It combines very high output capability with exceptional fidelity and coverage consistency. Its coaxial drive unit comprises a powerful 15” (380mm)/3” (75mm) voice coil LF driver and a 1.4” (35mm) exit HF compression driver with a 3” (75mm) pure titanium diaphragm.

The Coaxial Differential Dispersion technology employed in the CDD15 delivers more consistent audience coverage than systems with fixed X° x Y° coverage patterns, projecting relatively more output to the rear of the audience, while having wide horizontal coverage close-up. Its innovative CDD driver achieves ‘point source’ summation of the LF and HF sections, eliminating off-axis variations in frequency response associated with non-coaxial designs. Improving on conventional coaxial designs, which can suffer from high-frequency beaming, the driver features a static waveguide that merges seamlessly with the unique cone shape, maintaining the dispersion pattern out to very high frequencies.

The visually-distinctive birch plywood enclosure can be used in either horizontal (landscape) or vertical (portrait) orientation, with rotation of the driver easily accomplished by removing the screw-free, protective grille. The CDD15 can be suspended by eyebolts or by means of an optional horizontal yoke.

A full-range, passive two-way system, the CDD15 should be used with a compatible controller with appropriate limiter settings to provide system protection.

When used with the DX4.0 controller or an iKON amplifier, there are now enhanced DSP and FIR based pre-sets to deliver the absolute maximum performance and fidelity while limiter settings protect the integrity of the system.

New Favorite Work Shoe
Size: 9.5, Color: Black/Ivory
These Cole Haan Grand Crosscourt Daily shoes have quickly become my new favorite work shoes. They’re incredibly comfortable right out of the box, with just the right amount of cushioning and support to get through long days on my feet. I love that they look sleek and professional while still feeling casual enough to wear anywhere. The build quality is top-notch—durable materials and solid construction that make them feel like they’ll last a long time. Overall, these shoes strike the perfect balance between comfort, style, and practicality. I can honestly say I look forward to wearing them every day. Highly recommend for anyone who spends a lot of time on their feet but doesn’t want to sacrifice style.

Quality at affordable prices.

Best old guy shoes. They look great and have support for feet. You don't want cheap department shoes. You will pay for that in your later years.
