Pros: A classic four way floorstander with neutral, accurate sound and low distortion, now discontinued but worth buying used. An unusually accomplished 4-way floorstanding speaker for its era, with excellent on-axis linearity, good directivity, low distortion and bass to 51Hz. On-axis response stays within about +/-3dB, directivity is genuinely good both horizontally (~55 degrees) and vertically (~40-50 degrees), and the estimated in-room response closely matches what the reviewer actually heard. Harmonic distortion stays under 1% above 80Hz at both 86dB and 96dB, and multitone stays around 1% even at 96dB. Bass reaches a real F3 of 51Hz (F10 37Hz), with in-room extension into the low-mid-40s. The reviewer’s overall listening notes were essentially “nothing stood out bad or good”: a genuinely neutral, accurate speaker with a distinctive rounded-baffle look that avoids the diffraction issues a flat baffle this wide would normally have. Measured bass extension of 51Hz (-3dB), with a measured sensitivity of 88dB.

Cons: This is a 20+ year old, long-discontinued speaker only findable secondhand (Facebook Marketplace, Craigslist, audio forums): condition, driver matching, and component aging vary by unit, so audition before buying if at all possible. Demands a robust amplifier: impedance dips to about 3.6 ohms with an EPDR of 2.2 ohms. The small supertweeter shows minor breakup artifacts at the extremes of the vertical polar plot and some compression at very high output in the top octave, though neither was audible in normal listening.
