Installing Diluvio Underwater Speakers - need accessory list for casing

We have a client wanting to install underwater speakers in a concrete pool. We’ve decided to go with the Clark Synthesis AQ339 Diluvio Underwater Speakers (which are 20.3cm diameter).

I now need a full list of items required to install the speakers. (ie. the casing surrounding the speaker).

  • I know I need a niche and am considering the Hayward Large Plastic Pool Niche Concerete (SP0600U).
  • Will the 'Hayward Face Rim, Large Stainless Steel Colorlogic (SPX0525AS) fit this niche?
  • If so, do I need the Face Rim Lockscrew (SPX0980Z3)??
  • And Assembly Clamp with Screw, Nut, Washer (SPX0580BS)??
  • Do I need a speaker screen?
  • Have I covered everything? Are there any other parts I will need?

Do you ship to Australia?

Many thanks.
