  • Do you have a showroom?
    Yes, in Marlow, where you can experience our AV products at their best.
  • What are the delivery times for your products and shipping costs?
    These can all vary, especially as many products are custom-made to order. Ask for our price list PDF which features a page with all of this info.
  • How can I access CAVD's products on Specifi or WeQuote?

  • How long is the fibre optic cable that's supplied with the MLS system?
    The heavy-duty armoured fibre optic cable can be custom ordered to cover the distance from your MLS projector head position back to the rack location where you'll have the Modular Laser Light Source and Control Module components.
  • What cables do I need to run from the rack location to the projector head location?
    The armoured fibre optic cable and a single CAT5/6 cables for comms. At the head location, you will also need power and the video signal present (i.e. HDMI receiver).
  • Does the MLS projector head get noisy and hot?
    Much less than the equivalent projection technology! Because the light source is remote, the head doesn't have to 'work hard' but will need space (see manual) around it, basic controlled airflow and minimal sound absorption.
  • Can I reduce the 10,000 Lumens output for home cinema?
    Yes, currently on installations we have seen the output suitably reduced to around 30% which is easy to do in the settings.

  • Do invisible speakers really sound any good?
    You'd be very pleasantly surprised after a demonstration at our showroom. This kind of technology is big business and satisfies the end client with very clear sound, they, the interior designer and/or architect love invisible speaker technology like this.
  • Are the speakers good at reproducing bass?
    Nakymatone speakers, such as ECHT, MOOI, GOED and TWEE all present a clear, musical sound with 'warmth' in their tone. Bass or LF drivers are not present in these speakers as these run the very real risk of cracking plaster. For a full-scale sound, to get the party going, and to enjoy movies, add a Nakymatone subwoofer.
  • Can I just apply plaster straight to the black sound board of the speaker?
    No, they may be known as 'plaster-over speakers' but preparation is important before this last stage is done otherwise the plaster will not adhere. Do follow the instructions closely.
  • As well as plastering-over, can the speakers be veneered or fabric covered?
    Yes, however, the Nakyamtone speaker must still be fitted into plasterboard, filled and prepared as if it were to be plastered over, but instead, you can adhere a thin veneer or apply fabric.
  • What DSP settings do I need to combine Nakymatone speakers and their subwoofers?
    There are a few ways to get great results with this. Even though Nakymatone speakers can perform down to around 60-80Hz, we give the sub more work to do when combined as a system, i.e. to play 100Hz and below. For best results: 1) Use one of the Nakymatone analogue amplifiers 2) Use a pre-configured DSP amplifier from CAVD 3) If configuring a DSP amplifier yourself, considering a cross-over point around 95-105Hz then take time time listen and fine-tune

  • If a system comes with an ALC-1809 speaker controller, do I need a surround sound processor?
    Yes, the ALC powers the speakers, provides the correct EQ curves, filters and protection. It also sets the levels, delays and bass management for the particular room when you use the Automator software. An AV processor is required to be connected before the ALC, to decode HDMI signals to analogue outputs, to set the speaker arrangement i.e. 7.1 or 5.1.2 etc and lastly to give you volume control. Further AVP settings: Set speakers to LARGE, distances to ZERO, levels to ZERO, and any EQ OFF.
  • Can I just use the soundbar?
    The Theory Audio Design soundbar houses speakers for playing back Left, Centre and Right channels. You would need to add a Theory Subwoofer to use as a 2.1 or 3.1 system, plus an ALC or DLC loudspeaker controller.
  • What size TVs do the soundbars match?
    The sb range of soundbars are built to very closely (within just a few mm) match the width of 65, 75 and 85" TVs.
  • Are the Theory subwoofers active or passive?
    They are passive and are powered by the ALC or DLC rack-mounted DSP amplifiers supplied with your Theory system.
  • Do I need the 9 channel ALC-1809 amplifier if I'm not using 9 speakers?
    If you are using only 2, 3 or 5 speakers and a subwoofer or two, the ALC-1809 is still recommended. Unused channels are bridged to maximise output power to your configuration. The Automator software will provide a wiring diagram.
  • What parts do I need to order a Theory Audio Design IWS in-wall custom installation subwoofer?
    You will need the enclosure (ENC) to fit into the wall, and then when the room is ready, the speaker driver kit itself (SPKR). Lastly, if the subwoofer is not being hidden behind fabric, you will need the speaker grille kit (GRILLE).
