Versatile 2-Way Column Speaker System AS-1344

• alternative name: Heath Company

One of the finest column speakers you can buy, at a surprisingly low kit form price! Has two 1" dome tweeters and two 6 1/2 " full-range drivers mounted in separate woofer-tweeter arrays on adjacent sides of the cabinet to maintain well-balanced sound. The woofers are located well above the floor, so bass response is solid and well-defined. There is no mid-bass boom or resonance, so mid-frequencies come through loud and clear. The tweeters deliver a full 10 to 20 dB more offaxis response than conventional tweeters for bright, clean highs — and their amazing 270° dispersion pattern maintains a well-balanced stereo image regardless of speaker placement. Has a nominal 4 ohms impedance, so most amplifiers will deliver up to TWICE their rated 8 ohm power. Separately fused woofers and tweeters, flat/-3 dB level control. Light walnut-vinyl finish on all tour sides, simulated black slate top and acoustically transparent foam grille.
