As the names hint, the 305 (shown) carries a five-inch woofer while the 308 has an eight-inch woofer. The one-inch tweeter on both models is made of woven composite with a neodymium magnet.
Both offer JBL’s Control Waveguide technology for what the company says is an enhanced sweet spot. The waveguide is adopted from the higher-end M2 monitor. They also have the Slip Stream LF double-flared passive port.
Amps are Class D digital. Dual 41 W amps power the 305 with dual 56 W amps for the 308. XLR and 1/4-inch are the inputs.
The LSR305 has a reported 43 Hz–24 kHz frequency response range and the LSR308 has a 37 Hz–24 kHz frequency response range. Both have HF and LF trim pots.
Senior Manager, JBL Professional Recording and Broadcast Marketing, Peter Chaikin said, “Our goal with the 3 Series is to bring a new level of performance and accuracy to the market at most affordable price points.
Prices: LSR305 — $199.99; LSR308 — $325.
