1. Introduction The Tannoy B950 is a dedicated subwoofer designed for high definition sound reinforcement at low and ultra-low frequencies. It will extend the power bandwidth of SuperDual sound reinforcement systems to below 30 Hz, making it ideal for effects in club, theatre and concert sound reinforcement. Where ultra-low frequency enhancement is required with increased system headroom and maximum impact, combined frequency overlap is possible with cabinets like the B400.
For a worldwide list of distributors, please contact Neutrik directly: NEUTRIK AG: +41 7529666 Cable choice consists mainly of selecting the correct cross sectional area in relation to the cable length and the load impedance. A small cross sectional area would increase the cables series resistance, inducing power loss and response variations (damping factor). Connectors should be wired with a minimum of 2.5 sq. mm (12 gauge) cable. This will be perfectly satisfactory under normal conditions.
. Amplification & Power Handling As with all professional loudspeaker systems, the power handling is a function of voice coil thermal capacity. Care should be taken to avoid running the amplifier into clip (clipping is the end result of overdriving any amplifier). Damage to the loudspeaker will be sustained if the amplifier is driven into clip for any extended period of time. Headroom of at least 3dB should be allowed.
8. Positioning When a bass loudspeaker is used in an environment with boundary surfaces, its placement affects its frequency response. When such effects are properly understood, they can be used to great effect in producing the desired sound quality without the aid of additional amplification. Consider fig (a) in the diagram below, here we see a loudspeaker in free field or anechoic conditions. We measure its sound pressure level at a distance D, and refer to this as our reference level, or 0 dB SPL.
