The SCS145.5 is in fact a predecessor and downgrade from the CS480. The JBL SCS145.5’s satellite and center speakers, for instance, feature only a 3” midrange versus a 3-1/2” midrange. In addition, the JBL SCS145.5’s center speaker supports a sensitivity of only 86dB versus 88dB. Nevertheless, the JBL SCS145.5 does still maintain many similar qualities/features with its peer, such as a powerful 8” bass-reflex low-frequency subwoofer driver designed to produce quality beats that leave the room shaking, not to mention dual video-shielded midrange drivers for extra power and clarity. One major difference between the two models, however, is that the JBL SCS145.5 utilizes a much more lackluster design versus the CS480’s attractive, contemporary finish. The benefit to the SCS145.5 is clearly seen in its reduced retail price of $349.99, a $50 savings from the CS480.
