JBL L100 Century LoudSpeakers

The L100 was the consumer version of JBL's 4310/4311 pro monitors, and contained with it the same 12-inch woofer, 5-inch midrange and 1.4-inch paper cone tweeter. All of the drivers had large Alnico V magnets. The midrange and tweeter relied on a very simple crossover network, but the woofer had a direct connection to the amplifier. Some say that minimalist crossover played a part in the speaker's lively dynamics, the L100 epitomized early 1970s West Coast sound.

After its introduction at the 1970 summer Consumer Electronics Show in Chicago, the L100 went on to become not only JBL's most successful product up to that time but, from all indications, the best-selling loudspeaker system of the decade.

Bose 601 Series II Direct/Reflecting® loudspeaker system ( Sold from 1982 – 1986)

Love them or hate them, if nothing else, Bose speakers always do a good job of polarizing opinions.  These 601 Series II speakers from Bose feature no less than 2 woofers and four tweeters per speaker to achieve the 'Direct/Reflecting' component of their name.  I listened to this pair, connect to a relatively high power solid state amplifier (Meridian 559) and they sounded just fine.  Not my favorite speaker, but certainly better than many others I've heard.
