JBL's engineers developed this "no compromise" design for the HTi series of in-wall loudspeakers: pure-titanium tweeters, aluminum-alloy woofers and sophisticated crossover networks. HTi6 2-way in-wall loudspeakers deliver powerful, clear JBL sound in a space-saving package. The polymer-coated aluminum cone with rubber surround can handle plenty of bass for an extended listening session, such as a house party, without producing significant distortion. The speakers include integrated dog-ear brackets for retrofit applications.
