RSL Outsider II vs JBL Control 25T

Last updated: October 5, 2026

Short answer: both are discontinued, so this only matters if you are buying used. Used, the RSL Outsider II is the better pick: it ranks #6 of 13 outdoor speakers by sound quality (rated 3.4/5), against #13 (rated 2.2/5) for the JBL Control 25T.

RSL Outsider II vs JBL Control 25T

The RSL Outsider II is the more accurate, deeper-bass pick. Scores 2.93 on spinorama (6.07 with subwoofer) tested on Klippel NFS. Its measured preference score, a predictor of how neutral it sounds, is 2.93 against 0.32 for the JBL Control 25T. Its bass reaches about 87.9Hz before falling 3dB, against 150Hz for the JBL Control 25T. The tradeoff: Modest sensitivity and limited dynamic ceiling at high listening levels outdoor.

The case for the JBL Control 25T: Durable commercial outdoor construction with included InvisiBall multi-angle mounting system and built-in multi-tap 70V/100V transformer (30W, 15W, 7.5W taps). Watch for: Vendor spinorama measurements show a sharply band-limited frequency response optimized for commercial voice paging rather than music, yielding a low 0.32 preference score.

Buy the RSL Outsider II only if you find one used in good condition; both are discontinued, and it is the better rated of the two.
