Sterling series, Infinity's short lived speakers. These speakers closely resemble the SM (studio Monitor) series. They use the same Polycell tweeters. the heavy weight, but slightly different woofers.
The 2003 is a 2-way rugged system. These sound quite well and very crisp (thanks to the 1" polycell). The bass is sufficient considering it is only 8".

Not as pricey as the SM, but performs comparibly. I use them for my surround speakers and they do quite well. My fronts are SM 120's.
