MartinLogan Foundation B2 Bookshelf Speaker Pair Black

The versatility and relatively compact size of bookshelf speakers have long made them a popular choice. Those looking for a fuller-sounding stand or bookshelf solution will be hard-pressed to find better value than the Foundation B2. Its 6.5" aluminum mid-bass driver delivers impressive bass while the S Gen2 Obsidian Folded Motion tweeter works within the Folded Motion waveguide to cover your listening area with beautiful sound. The Foundation B2 is also fully compatible with STAND25 to create a solid stand mounting solution.

MartinLogan has over 40 years of history, with a unique research and development laboratory in the world, equipped with the largest private anechoic chamber in North America.

Among the many excellences completely developed by the manufacturer, the thin film tweeter, and just to give one example.

First of all on board the range is the FMT S Gen2 tweeter, developed specifically for Foundation, and combined with the Folded Motion waveguide: together they are able to deliver great quality sound with a homogeneous and controlled dispersion, ensuring the same performance throughout the room and reducing some of the negative effects of room acoustics. The Gen2 S-shaped tweeter uses an extremely low-mass diaphragm that “squeezes” air, requiring significantly less excursion than a typical 2.5cm dome tweeter. Folding the membrane into an accordion-like structure increases the playable surface area, keeping the tweeter’s dimensions relatively compact, allowing for particularly clear and believable reproduction.

The Folded Motion Waveguide, in addition to improving the coherence of the reproduction, allows, as we were saying, an increase in the coverage area with controlled dispersion, which improves the natural emission of the tweeter by 10° in all directions, for a pattern of as much as 90° x 90°.

For the mid and low range, ad-hoc components with an aluminium membrane have been developed, capable of offering low mass and great energy thanks also to the enhanced magnetic motor.

The McCracken-Vojtko Crossovers could not be missing, now a tradition at Martin Logan, developed by the manufacturer over the years, and which now guarantees the best compromise between low distortion, in-room measurements and in-depth blind listening tests so as to develop a unique sound signature for each model.

Another aspect of great importance, much looked after in the Foundation Series, is the compensation of the sound bounce of the floor, and to do this, the Martin Logan engineers have designed the tower models using the floor to create a more coherent, natural and accurate compared to conventional designs.

To complete, finally, a design that although classic has numerous particularities, such as the 4 supports on the base that adapt to any floor surface, or the Stealth system that holds the grilles in place, allowing the listener to customize the look of each speaker even allowing them to rotate to change the grain of the fabric.

It is the largest bookshelf speaker in the Motion Foundation Series, offering impressive detail and a range that is completely unexpected for a speaker in its category.
