FES 10 – Horn Loaded Mid High Cabinet


The FESTIVAL 10 mid high cabinet is is part of our premiere touring range, ideally suited for concerts and outdoor events.

The innovative horn loaded enclosure incorporates two 350 Watt RMS 10” driver specifically designed to withstand the excursions typical of high level mid frequency reproduction and includes a 2” exit compression driver mounted on a 90 degree horizontal 60 degree vertical cast aluminum horn flare.The mid high cabinet can only be used actively with an external controller.Large internal flares ensure frequency dispersion is maintained and resonance is kept to a minimum.

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 Blackag Group FES10 is designed to be used with professional power amplifiers capable of producing a minimum specification of 850w – 1700w 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 FES10 Cabinets can be used with a wide array of Blacka Group speakers. Typical configurations are listed below

Nightclub: FES LMF Low Mid Cabinets – BS15 – BS18 – SS1000 Bass Cabinets

Live Music: – FES LMF Low Mid Cabinets – BS15 – BS18 – SS1000 Bass Cabinets

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 Acoustics 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.



    1. The FES10 is a relatively heavy unit and should always be lifted by two people.
    2. Ensure that the floor or stage is level and solid.
    3. Do not stack speakers too high when outdoors as high winds can topple stacks.
    4. Be aware that these speakers produce very high levels of output. They can move or creep, to avoid any problems it is advisable to strap the speakers down when stacking


    Suspending the system should only be done by qualified personnel following safe rigging practices. Secure fixings to the buildings structure are vital. Seek help from architects, structural engineers or other specialists if in any doubt.

    The FES10 loudspeaker enclosures are designed for touring and installation applications and can be suspended singularly or multiple arrayed vertically or horizontally by means of the threaded inserts provided within the cabinet and an additional frame and rigging components. The FES10 enclosures are fitted internally with steel corner reinforcement brackets to ensure that each cabinet is strong enough to be hung from its top. Never suspend one enclosure from another to form an array or cluster using these fittings.

    The common practice of using commercially available eye bolts for suspension should only be undertaken with great caution. Eye bolts are strongest along the thread axis. Angling the enclosure will result in an angled pull and it is important to use bolts that are safe in these circumstances. Only forged shoulder eye bolts should be considered and it is important that the thread length is at least 40mm. A flat washer should be inserted between the eye bolt and the enclosure. Formed eye bolts i.e. those which are formed from steel rod bent into an eye should be avoided.
