Q Acoustics Concept 500 – High-End Floorstanding Speakers (Pair)
The Q Acoustics Concept 500 is a flagship high-end floorstanding loudspeaker designed for refined stereo listening. Combining dual 165mm mid/bass drivers, a 28mm high-frequency driver and advanced cabinet-control technologies, it delivers a wide soundstage, strong dynamics and highly controlled reproduction while minimising unwanted cabinet resonance.
Key Features
-
Dual 165mm Mid/Bass Drivers: Engineered for powerful, controlled low frequencies and natural midrange reproduction.
-
28mm High-Frequency Driver: Delivers detailed and extended treble response up to 30kHz.
-
Gelcore™ Cabinet Construction: Uses multiple cabinet layers separated by non-setting gel to convert unwanted high-frequency cabinet vibration into heat.
-
P2P™ Bracing: Point-to-Point internal bracing reinforces areas of the enclosure most susceptible to low-frequency vibration.
-
HPE™ Technology: Helmholtz Pressure Equalisers help manage internal pressure and reduce unwanted standing-wave effects inside the cabinet.
-
Adjustable High-Frequency Level: Rear links allow ±0.5dB treble adjustment to suit the room or listening preference.
-
Bi-Wire Terminals: Supports conventional single-wiring or bi-wiring with compatible amplifiers and speaker cables.
-
Premium Dual-Finish Cabinet: Available in sophisticated combinations including Gloss Black / Rosewood and Gloss White / Light Oak.
