JBL Professional now has FIR or Finite Impulse Response tunings for certain Control Contractor Series loudspeakers to further enhance their performance. These FIR filters optimize both frequency response and phase response to a finer, more precise setting than has typically been possible with standard IIR "parameter-based" filters. Additionally, these FIR filters were designed to meet JBL Pro’s new V6 FIR tuning standard.
The new V6 features include: Equalization to a neutral frequency response, improved linearized phase response above 300 Hz, and then you now can start, with a known flat voicing for further equalization, to the needs of the particular install.
The V6 FIR tunings are for COL600 & COL800, SLP12/T and SLP14/T, GSF6 and GSF8 and Control 68HP products. The posted tunings are for use with Crown DCI-N and DCI-DA power amps.
All models feature premium multi-tap transformers for use in distributed systems and are switchable for direct operation. These are sleek, elegant and non-intrusive speakers and winners of prestigious international design awards for industrial design excellence.
