The Bose 601 Series 2 speakers in excellent condition - 1980's

Bose 601 Series 2 speakers in excellent condition The Bose Model 601 Series II, like the other Bose speakers, is designed for "direct/reflecting" operation in which a large part of its total acoustic output is reflected from one or more room boundaries before reaching the listeners (part of the speaker's output is directed forward to the listening area in the conventional manner). Externally, the Model 601 Series II resembles a conventional floor-standing speaker. Its front and top are covered by an attractive dark-brown textured grille cloth. The top section is surrounded on the top and three sides by the grille and louvered plastic panels and is open to the rear. The top grille is hinged at the front and when lifted reveals an 8-inch woofer, tilted about 30 degrees forward of- the vertical, and four unbaffled 3-inch cone tweeters angled to the sides and rear. Pulling off the front grille, which is integral with the top grille and is retained by sturdy plastic pins, reveals a second 8-inch forward-facing woofer on the front of the speaker cabinet. The two woofers operate together up to 2.5 kHz. The four tweeters overlap the woofer range, operating down to 1.5 kHz. The two rear-facing tweeters are angled slightly upward, radiating across the front of the top woofer and outward toward the wall behind the speaker at a horizontal angle of about 30 degrees. The front tweeters are angled outward at almost 45 degrees and are nearly horizontal. The woofers are in separate internal sub-enclosures, which are ported individually into the main volume of the cabinet and from there to the outside through a single opening on the top. The overlap in frequency coverage between the tweeters and the woofers, allowing them to operate together over nearly an octave, is said to minimize phase-shift effects and audible coloration of the sound. Also, since several drivers are operating together in each part of the frequency range, their individual response irregularities tend to average out and give a smoother overall frequency response. There are no user-adjustable level or balance controls. In the rear of the enclosure are binding-post speaker terminals and a third (covered) terminal reserved for use with future (unannounced) Bose electronic components. The Bose Model 601 Series II is nominally an 8-ohm system, suitable for use with amplifiers rated from 20 to more than 150 watts output. The tweeters are protected from burn-out by a small thermal device whose resistance increases during periods of high input level, limiting the power delivered to the tweeters without silencing or even audibly affecting the sound of the speaker system. When used with amplifiers rated at more than 100 watts per channel, Bose suggests connecting a 2-ampere fuse in series with the line to each speaker.
