IKONOKLAST2DX4

Now, the "magic" of the Ikonoklast triple acoustic length (3/4-wave) transmission line system "sets the Lowther DX-4 driver free to sing its heart out," in a nearly full range system.

The "heart" of the Lowther DX-4 driver is the exclusive rare earth magnet/hi-ferric voice coil system. This innovative feature allows not only ultra-high sensitivity, but also provides superior control of the cone movement, delivering jack hammer-like attacks, deliciously delicate trailouts, and the most natural vocal and instrumental textures "south of $40,000." But effective coupling of the DX-4’s full range output to the listening room is a daunting challenge. Use of sealed, ported or open baffle enclosures can be expected to largely sacrifice the lowest two octaves, likely requiring the use of a slow, high mass subwoofer with a sound-degrading crossover network.

Enter the Ikonoklast_2DX4, at only 24 inches high, 11 inches wide and 16 inches deep. Remarkably, our triple length, ¾-wave transmission line bass coupler has been squeezed inside this unassuming shape. By precisely stuffing the entire length of the folded transmission line passageway with the correct density of a specific damping substance, the sound wave is slowed accurately to a fraction of its speed through air. Far from degrading the performance, the stuffing actually smooths the bass response, by lowering the Q of the transmission line’s half wave resonance. The system response is thereby extended deep into the lowest octave, without a narrow response peak. The result is the sort of powerful room-shaking low bass, typically associated with subwoofers, but without their muddy loudspeaker-like sound.

But the powerful low bass of the Ikonolast_2DX4 is much clearer and more defined, because the ¾-wave acoustic transmission line length has been aligned to precisely control the driver’s main resonance, eliminating the loudspeaker-like quality of a typical woofer or subwoofer, and allowing reproduction of the most subtle bass textures and nuances that seldom are heard except in unamplified, live music.

Although awesomely clear low bass is a key distinguishing characteristic of this system, most of the music is in the midrange, and this enclosure has an important design feature that allows the DX-4 driver to shine in the midrange, very much like an open baffle system. Instead of the rear wave from the cone being reflected from the flat back of the cabinet, the cylindrical shape of the internal terminating section of the transmission line reflects midrange energy in multiple directions. This prevents midrange standing waves from propagating inside the cabinet and being re-radiated through the cone. The listening effect is an almost total absence of any ,boxy quality of the reproduced midrange.

Because the DX-4 driver has excellent high frequency response, with wide dispersion, no tweeter is required for thrilling, virtually full range reproduction.
