O'hEocha Audiophile's Speakers | BMW 3D
Made in western Ireland by former BMW designer Aonghus O'hEocha, founder of O'hEocha, manufacturers of preeminent audio systems, these hand-crafted 200-watt isobaric speakers provide the clearest three-dimensional soundstage performance available.
The 1" tweeter drive unit is mounted on an isolated rubber insert at the top of the the assembly with a control spike that minimizes resonance transfer from midrange to treble.

The two 61/2" midrange drive units, one forward-firing and one rear-firing, are mounted on their own suspension system that prevents low frequencies from being transferred to the spherical midrange enclosure; the spheres rotate horizontally, allowing you to fine tune your listening environment without having to move the spe akers.
Two 11" subwoofers are mounted cone-to-cone in an isobaric configuration that generates thunderous bass, providing the enclosure with an effective volume of 1 1/4' cu., resulting in extended bass frequency response equivalent to a speaker enclosure twice its size.
Both speakers have two bass reflex ports for their subwoofer assemblies that equalize air-flow throughout the enclosure to minimize resonance common to single-port designs, resulting in distortion-free bass that can be tuned to reach frequencies as low as 25Hz.
The speakers single-piece hyperboloid enclosures are made of aircraft grade aluminum and a PVC/steel composite, reinforced by 3/8" diameter horizontal and vertical bracing rods that ensure maximum rigidity and minim ize sound wave distortions.
