James Loudspeaker OT66Q-4 - Quad Tweeter 4 Ohm

Product Overview

The James Loudspeaker OT66Q-4 is a high-output quad-tweeter speaker featuring a QuadraTech four-tweeter array, configured at 4 ohms for low-impedance commercial audio. Built for installations needing detailed, well-distributed high-frequency coverage, this speaker connects directly to low-impedance amplifier channels. The QuadraTech configuration places four tweeters in the array for extended high-frequency dispersion and clarity. Specifiers selecting a 4-ohm quad-tweeter speaker for high-output detail in commercial AV will find the OT66Q-4 a targeted choice.

Product Description

The OT66Q-4 belongs to the OT high-output series within the James Loudspeaker collection, a family of speakers built for higher sound pressure and intelligibility than standard background-music models. The "Q" designation indicates the QuadraTech quad-tweeter configuration, with four high-frequency drivers delivering detailed, evenly distributed top-end coverage across the listening area. This quad-tweeter approach supports clarity in spaces where high-frequency detail and dispersion are priorities. Within the OT series it shares the QuadraTech platform with models such as the OT88Q-70, while offering the 4-ohm low-impedance interface.

The 4-ohm configuration makes this model a direct match for low-impedance amplifier channels, supporting high-quality audio without a line transformer. Installations requiring constant-voltage distribution over long cable runs are served by the 70V OT66Q-70 sibling. The quad-tweeter array gives the OT66Q-4 strong high-frequency presence and even coverage, suiting it to commercial environments where intelligibility and detail carry the application. The result is clear, high-output reproduction with consistent top-end dispersion across the space.
