Soundfactor SF25 from JBL

JBL’s new SoundFactor SF25 is a portable two-way speaker system with two 15" low frequency transducers. Intended for live music and music playback/DJ applications, the SF25 reflects the increasing market acceptance of the dual 15" configuration, say JBL. The SF25, they say, is more of a three-way system in that the lower woofer is actually rolled off at a lower frequency than the upper woofer. While this results in a more expensive network, the improvement in mid-range performance makes it worthwhile. The SF25 is especially useful in applications where additional low frequency power is needed, but subwoofers are not practical. The SF25 has a power capacity of 500W (2000W) and maximum SPL of 133dB. SoundFactor's advanced network design for its crossover includes heavy gauge wire inductors for low distortion and SonicGuard high-frequency driver protection. The SF25 is constructed from carpet-covered 3/4" MDF - a material that is, say JBL, structurally and acoustically superior to the particleboard used by many competitive products. All-metal handles and an 18 gauge, full metal grille are also used.
