Optimus PRO LX5 Bookshelf Speaker #40-4061 With Linaeum Tweeters

 Optimus PRO LX5

• The PRO LX5 was a “top-of-the-line” bookshelf/stand-mount speaker from the mid-1990s under the (then) RadioShack / Optimus label. 

• It uses a 5″ polypropylene-cone woofer for bass/midrange, plus a distinctive “Linaeum” dipole ribbon tweeter (≈ 2" × 4") to handle highs. 

• Dimensions per speaker: about 10.5" × 6.375" × 6.5", weight ~7.5 lbs. Nominal impedance is 8 Ω; sensitivity ~81.5 dB/2.83 V/m. Recommended max amplifier power ~100 W. 

In short: a compact 2-way bookshelf speaker combining a conventional woofer with a more “exotic” ribbon tweeter — unusual for consumer-grade speakers of that era.
