RF10 – Single Loaded Bass Cabinet

Category:

The RF10 bass cabinet is ideally suited for small retail spaces and restaurants.

The compact ported reflex enclosure incorporates a 350w RMS 10” bass driver specifically designed to extend the low frequency and provide a warm punchy bass in compact environments. A small shelf port ensures optimum cabinet tuning. The RF10 is ideal for permanent installations in small venues that require extended bass frequency for music reproduction played at a background level.

Each connector panel has two Neutrik Speakon connectors wired in parallel. The second connector allows use of a short link lead to power a secondary parallel loudspeaker. The connectors are wired as follows:

  • 2 Core cable
  • Pin 1 Positive
  • Pin 1 Negative

When connecting Blacka Group sound reinforcement to an amplifier it is recommended that the return resistance of the cable used is less than one tenth of the normal impedance of the system or systems in parallel the chart below gives an indication of the maximum possible cable runs for conductor cross sectional areas.

The Blacka Group RF10 Cabinets are designed to be used with professional power amplifiers capable of producing 350w – 700w power output into 4 ohms.

Care should be taken to avoid amplifier clipping, it is important to understand that a low power amplifier driven into clipping is more likely to damage a loud speaker than a higher power amplifier used within its ratings. Primarily because music signals have a high peak to average crest factor. When an amplifier is severely overdriven its output waveform is clipped resulting in squared off peaks and thus reducing the crest factor. In extreme cases, the waveform can approach that of a square wave. An amplifier is normally capable of producing far more power under these conditions than its undistorted rated power output. The use of very high power amplifiers with outputs greater than those recommended is discouraged.

Care should be taken to avoid switch on surges, which can result in momentary power peaks in excess of specified ratings. When powering up a sound system it is important to switch on the amplifiers after the mixer and control electronics have stabilised. When powering down the system, reverse the sequence and switch off the amplifiers first.

The RF10 units can be used with a wide array of Blacka Group speakers. Typical configurations are listed below

Small Retail / Restaurant : TFR 5T – TFR 25T – TFR 801 – TFR 1001

It is important that loudspeaker systems are used in a safe manner. Please take some time to review the following points concerning use of Blacka Group Loudspeakers.

Professional loudspeakers are capable of producing extremely high sound levels and should be used with care. Hearing loss is cumulative and can result from levels above 90 DB if people are exposed for a long period , never stand close to loudspeakers driven at high level.

STACKING

  1. Ensure that the floor or shelf is level and solid.
  2. Be aware that these speakers produce very high levels of output. So if place on a shelf area be aware that they can move or creep.
