Technology meets the challenge in a tough arena.
The CM750DSC 7in. directed soundfield loudspeaker from Niles Audio has a twist-and-lock baffle and frame mechanism for easy mounting, and the woofer assembly pivots up to 20 degrees to direct bass and midrange. The 8Ω unit takes 10W to 125W of amp power and delivers a frequency response of 55Hz to 21kHz ±3dB. There is also a three-position tweeter level control.
Designed for in-wall or ceiling installs, the three-driver, two-way AMS-350 from Paradigm uses a 1in. PTD dome tweeter and two 8in. mineral-filled woofers with polypropylene cones to produce audio from 55Hz to 20kHz with a crossover at 1.8kHz and handling power up to 150W. The attractive rectangular unit consists of a die-cast chassis and has a paintable white grille.
The Aramid 6.5in. fiber cone woofer and 1.5in. titanium dome/aluminum cone tweeter in the S-IC671A loudspeaker from Pioneer Electronics handle a maximum input power of 130W and deliver a frequency response of 32Hz to 40kHz with a crossover frequency of 2.2kHz. The grille can be painted to match room décor.
In the new wave of IP-delivered AV, Polk Audio presents the LC-80i-IP loudspeaker using IP audio distribution. The unit sports built-in DSP for room optimization using the Performance Optimization Wizard software via USB or IP connection. The unit's 100W power is handled by the 25W tweeter and 75W woofer.
Better high-frequency dispersion is the idea behind the twin tweeters on the C800TT from Proficient Audio Systems. This model features an 8in. graphite woofer with rubber surround and twin pivoting 1in. aluminum tweeters along with bass and treble contour switches. The unit handles 150W and exhibits a 28Hz-to-22kHz frequency response.
The CW180R from PSB Speakers has its 8in. woven fiberglass woofer and 1in. aluminum dome tweeter mounted coaxially, and together they produce a frequency response from 38Hz to 21kHz with a typical 90dB SPL. The 8Ω unit can handle 20W to 100W of power and features dual, gold-plated 12 AWG spring-loaded terminals.
