product features

The Boston Acoustics HSi 430 features a round bezel and the HSi 435 a square bezel.

Both models are 2-way con gurations, with 3½ ” woofers and ¾ ” tweeters. Each model

features a metal back enclosure with front- ring ports for extended bass response,

o ering uncompromised sonic performance.

Featuring dual high-performance 6” woofers, the HSi S6W2 in-ceiling subwoofer is the ideal

solution for consumers with who desire a virtually hidden and high-quality in-ceiling audio

installation. The subwoofer’s built-in crossover allows for the same stereo ampli cation as the

main speakers, and integrated output terminals allow for wiring of either one or two pairs of

full-range in-ceiling speakers. A bandpass enclosure delivers the high output bass necessary

for optimum room- lling sound.

performance features

For  exibility in crafting rich, room- lling soundscapes, the HSi 430 and HSi 435 speakers

feature an innovative switchable highpass  lter, which removes bass frequencies below

180Hz. When using the speakers without the HSi S6W2 subwoofer, the highpass  lter may be

switched o for optimum performance. However, if the speakers are being used full-range in

high sound level applications, the highpass  lter helps protect the speaker. For use with the

HSi S6W2 subwoofer, the highpass  lter may be switched on for optimum performance.

Constant voltage (CV) versions of the HSi 430 and HSi 435 are also available.
