For uncompromising sound in a slim, discreet design, you'll be hard pressed to top the Meyer Sound UP-4slim. This 500-watt powered loudspeaker comes loaded with dual 4-inch low-frequency drivers and a 1-inch high-frequency driver arming you with a 65Hz to 18kHz operating frequency range and a linear peak SPL of 116.5dB — all with near-imperceptible distortion.
