PMC GB1 Floor standing speakers

PMC GB1 are lightweight floor speaker systems. Stands are screwed to them for better stability. On the faceplate the single 140-mm mid-woofer with the basket made of magnesium alloy and dome fabric tweeter with the caliber of 27 mm are hidden under very small dust cap. Main tricks are inside. Fourth ordered crossover instead of phase inverter is unchanged for PMC design of Transmission Line, and the length of labyrinth reaches 2,4 meters that speaks of setting to very low for such miniature systems frequency. GB1 are available in four variants of finish. The manufacturer assures that this innocuous-looking system is able to approve itself not only in home conditions, but also in the role of studio monitor. If it doesn't have PMC label, I would not believe.

By the quality of playing of sound stage these PMC GB1 can really have the edge over not only classmates, but also precise studio systems. There are no any fails in the transfer of sound space and signs of not enough clear separation at the plans. But is everything good with other qualities? The upper range is played without frills, discants are transferred dynamically and in details. I would describe the midrange in the same way, but with the proviso: in the lower part of vocal band the sound not always seems to be legible and is blurred by barely noticeable spurious resonances. Speaking about bass, it is very good.

PMC never fails to amaze by its ability to extract from low-power by sight woofers not only quality, but quantity of low frequencies. Although it is recommended to take GB1 as a rear system in the theatrical system with more powerful OB1, I don't see any obstacles to use these speaker systems as the main ones.
