Boston Acoustics A70 speakers with a Marantz amplifier, a classic air suspension design, 8&quot; paper cone woofer, dome/cone tweeter, simple crossover, straightforward cabinet. Vivid stereo imaging, a huge sense of detail, and amazing bass for their small size. You don&#x27;t need wildly expensive &quot;audiophile&quot; parts to get great sound. Boston Acoustics typified the &quot;East Coast Sound&quot; that emphasized natural sound with neutral treble balance. Very 1970s!
