Spendor QT-100
Not much is documented about the Spendor QT-100 beyond a handful of period reviews and advertisements. What the record shows is a compact powered monitor introduced in 1997, aimed at the project studio and serious home-listening market. Sound-on-Sound-UK (1997-08, p.47) reviewed the QT-100 at a price of £704 per pair. It called the QT-100 a very compact package with a frequency response of 70Hz - 20kHz ±3dB, and each pair matched to within 0.75dB across the full range. The crossover was set unusually high at 5kHz, so the main driver handled the vast majority of the frequency spectrum.
The same review noted that the QT-100 shared the chamfered top and side edges of the latter design, a detail meant to minimize edge diffraction. The reviewer found the QT-100s a tad bright after years of listening to softer BBC-monitor voicing, but said careful positioning did a lot to correct it. In accuracy, transients and neutrality, the Spendors compared very favorably with far larger cabinets. They nearly matched those cabinets in the weight of their lower octaves, and the reviewer was strongly impressed overall.
An advertisement in Sound-on-Sound-UK (November 1997, p.267) listed the QT-100 as a powered monitor at €599 (likely a later or promotional price). It claimed the internal amplifier was optimized for maximum enclosure performance and could deliver sound pressure levels suitable for serious monitoring. Beyond these fragments, almost nothing is recorded about the model's exact production years, total numbers made, or subsequent revisions.
