Small speaker with big sound! This tiny speaker measures 5.9" wide x 10-5/8" tall x 8-11/16" deep, with an internal volume of approximately 5.5 liters, but sounds MUCH larger. It features the new 20mm D2010/852100 neodymium magnet tweeter and 15W/8534T00 Phenomax cone midwoofer. Fittingly, both drivers are from the Classic family in the Scan-Speak line.
