JBL’s LSR family of professional studio monitors has spawned some seriously noteworthy active studio monitors over the last decade, with the Room Mode Correction system-equipped 4300-series (reviewed in SOS
April 2006 and on-line here
) coming to the fore most recenly.
The latest additions to the LSR group of products are the 2300 series, aimed at the home- and project-studio user. The series comprises three models: the 2325P, a two-way nearfield monitor with a five-inch low-frequency driver; the 2328P, another two-way nearfield with an eight-inch LF driver; and the 2310SP, a subwoofer with a 10-inch driver. All three new products are active, with the nearfields benefitting from a bi-amplified design.
Staying true to the family heritage, the 2300-series products have been developed using JBL’s Linear Spatial Reference (LSR — hence the name) technique that involves the designers taking 70 measurements to analyse and perfect the speakers’ performance. As a result, the manufacturers say that the new monitors deliver “superior imaging and smoother frequency response”.
Being a value-oriented range, the 2300 products don’t feature the room-correction functions or front-panel meters of their older and more expensive siblings. Even so, bass extension figures are impressive: JBL say that the five-inch model will reproduce frequencies as low as 43Hz, while the eight-inch version goes down to 37Hz. The subwoofer operates as low as 29Hz, and has built-in crossover circuitry that enables it to be connected directly to the LSR nearfields, or to any other monitoring system. The two nearfields can be hooked up using XLR, balanced jack or RCA phono connections.
