Features Of The JBL LSR6328P:
The JBL LSR6328P studio monitor is the choice for stereo and multi-channel music and post audio applications where exceptional accuracy and high SPL are required.
The LSR6328P studio monitor is designed for use in critical stereo and multi-channel monitoring applications that require exceptional spectral accuracy and high SPL capability. The LSR6328P combines the latest in JBL's renowned transducer and system technology with psychoacoustically derived spatial response criteria, resulting in a more accurate studio monitoring reference system. In this design process, the system's frequency response over the forward listening range (+/-15 degree vertically and +/-30 degree horizontally) is optimized, as opposed to the conventional approach of optimizing the response directly onaxis. This design approach involved careful component design, selection of crossover frequency, and precise baffle geometry and detail. The result is a system that can be used for the most critical judgments of recording balance, image placement, and equalization. The matching of the LSR6328P system to the listening environment is further enhanced through the use of RMC, an analysis/correction system that identifies and corrects response to compensate for the dominant low frequency standing wave in the system's room response. In addition to a rich array of performance features, the JBL LSR6328P has a reinforced enclosure and integral mounting points to facilitate wall mounting. Recessed handles facilitate easy positioning of the loudspeaker in the environment and aid in transportability.
218F Low Frequency Transducer
The 8" woofer is based on JBL's patented Differential Drive(TM) technology. With dual 1.5" voice coils, power compression is kept at a minimum to reduce spectral shift as output power levels increase. An added third coil located between the drive coils acts as a dynamic brake to limit excess excursion and reduces audible distortion at maximum levels. The cone is made of a carbon fiber composite forming a rigid piston and is supported by a soft butyl rubber surround.
053TiS High Frequency Transducer
The high frequency transducer has a 1" composite diaphragm integrated with an Elliptical Oblate Spheroidal (EOS) Waveguide with wide uniform dispersion that is critical to the smooth spatial response required in today's working environments. The driver is shielded to minimize the interference when used in close proximity to video monitors.
Bi-amplified Power System
The JBL LSR6328P combines two high power amplifiers with an active dividing network. Included are over 250 watts of continuous low frequency power and 120 watts for the high frequency section. The active dividing network produces a 36/dB-per-octave Linkwitz-Riley type response for smooth transition between transducers, both in the frequency and time domains. This results in exceptional imaging and a lack of time smear, and the circuitry also yields a tonal-artifact free noise floor.

Features Of The JBL LSR6312SP Subwoofer:
The JBL LSR6312SP powered studio subwoofer is designed to provide low frequency extension and sophisticated bass management capabilities in stereo and multi-channel applications where exceptional spectral accuracy and high-SPL are required.
The LSR6312SP powered studio subwoofer is designed to provide low frequency extension and sophisticated bass management capabilities in stereo and multi-channel applications where exceptional spectral accuracy and high-SPL are required. The system includes JBL's RMC(TM) Room Mode Correction circuit. The system is designed around JBL's 252F LF transducer, which uses dual voice coils and a powerful neodymium magnet. With the patented Differential Drive(TM) technology, power compression is kept to a minimum. An additional third coil located between the two drive coils acts as a dynamic brake to limit excess excursion and reduce audible distortion at the highest operating levels. The cone is made of a carbon fiber polypropylene composite forming a rigid piston area supported by a soft butyl rubber surround.
A 260-watt continuous power amplifier is integrated into the JBL LSR6312SP system and provides correct drive levels for optimized frequency response. Amplification is class A-B in an all discrete topology.
The subwoofer derives its input by summing Left, Center, Right and Direct LFE inputs. Subwoofer signals can be selectively derived from the front channels or from the Direct input alone using a simple Remote Bypass contact closure switch. User-selectable settings are provided for -10 dBV, +4 and +8 dBu sensitivity. For calibration and level matching of the system, an Input Trim control can be inserted into the circuit for continuously variable attenuation of the system input. Additionally, the Direct input has a dedicated Input Trim. The LSR6312SP includes Left, Center and Right channel outputs to feed external satellite speakers. The LCR outputs are high-passed at 80 Hz. A 1/4" jack allows connection of a Remote LCR Bypass contact closure switch. When the switch is used, full-range signals are sent to the Left, Center and Right satellite speakers and the subwoofer derives its feed from the Direct input only.
Subwoofer low pass filtering uses a steep 5th order low pass section to minimize the possibility of localization of the subwoofer's acoustic output. High pass filtering for Left, Center and Right outputs is 12 dB/octave. For convenience, input receptacles are Neutrik "Combi" type, which accommodate both XLR and 1/4" connectors.
Six DIP switches on the input panel allow the user to precisely adjust the gain and response of the system. DIP switch one inserts a variable attenuator inserted into the circuit allowing the level to be trimmed from 0 to -13 dB. The Left, Center, Right and Direct inputs default to -10 dBV sensitivity. Using DIP switches 2 & 3 the user can set input sensitivity for all inputs to +4 dBu, +8 dBu or +12 dBu. A +4 dBu signal to any input will drive the output level of the LSR6312SP to 96 dB SPL at 1 meter with input sensitivity set to +4 dBu.
Switch 4 inverts the signal polarity of the subwoofer feed. This is used to correct for placement mismatch between the subwoofer and satellite spacing. Due to the varied placement options available in audio production environments, it is suggested that this switch be adjusted after the final placement of the system has been determined.
