Built for demanding commercial AV installations needing high intelligibility and output, this bi-amplified speaker pairs full-range reproduction with a four-tweeter high-frequency section. The 70V configuration with line transformer makes it a direct fit for distributed audio across long cable runs. Specifiers seeking a full-range quad-tweeter bi-amp 70V speaker for high-output commercial coverage will find the OT88Q-70 a focused solution.\u003c\/p\u003e\u003ch2\u003eProduct Description\u003c\/h2\u003e\u003cp\u003eThe OT88Q-70 sits in the OT high-output series within the \u003ca href=\"https:\/\/creationnetworks.net\/collections\/james-loudspeaker\"\u003eJames Loudspeaker collection\u003c\/a\u003e, a family of speakers built for higher sound pressure and extended intelligibility than standard background-music models. The \"Q\" designation indicates the QuadraTech quad-tweeter configuration, placing four high-frequency drivers in the array for detailed, well-distributed top-end coverage. Its bi-amp architecture separates the low and high-frequency sections for independent amplification, supporting cleaner reproduction at high output levels. As a full-range model it covers both music and speech, distinguishing it from the tweeter-focused OT66Q-70 within the same series.\u003c\/p\u003e\u003cp\u003eThe defining feature of this model is its 70V configuration, which includes a line transformer for constant-voltage distribution. This lets many speakers share amplifier capacity across long wiring runs, the standard method for large commercial and public-address installations. Installations using low-impedance amplification within the OT family are served by 4-ohm models such as the OT84-4. The combination of quad-tweeter high-frequency coverage, bi-amp operation, and full-range output makes the OT88Q-70 suited to spaces where both clarity and level matter. The result is high-output, intelligible reproduction across large commercial environments.\u003c\/p\u003e\u003ch2\u003eKey
