Two Bottlehead Paramounts are already playing music as well as two Pi4 speakers. You can see them in the second picture in a temporary setup testing them with the Outlaw processor that I have already purchased.

The other three Paramounts are in the making and hopefully will be finished before the house. The other three speakers are almost finished. The cabinets and crossovers are done and mounting and connecting the drivers is all that is required.

Judging by the sound of the first two channels it looks promising :>)
