Description
TOA TC-651M Reflex Paging Horn Speaker 50W @70.7/100 V Mounting Bracket Included
Product Details
The TOA TC-651M is a round reflex horn — 400 mm across, 50 W, with a line transformer for 70.7 V and 100 V distributed systems. The reflex design folds the horn path back on itself, which is how it gets its throw from a shorter body than a straight flare of the same output.
It runs 200 Hz to 6 kHz at 111 dB, reaching lower than any other horn in this group. Taps run from 50 W down to 7.5 W on a 70 V line and 50 W down to 15 W on 100 V. Note that this model is transformer-only: there is no low-impedance version of it, so it belongs on a constant-voltage line.
The housing is rated IP65 against dust and water: an aluminum horn flare with powder coating, an ABS reflector and rear cover, and stainless steel bracket and fixings, which is what lets it live outdoors without the hardware rusting into the wall. A mounting bracket is supplied with the speaker.
