Right then Meat Men, time for you to annihilate me with ridiculous suggestions and advice. But here goes anyway…
Over the next couple of months I will have the chance to convert a double garage into a dedicated listening room. Garage is approx. 21’ x 20’, central wall to be removed and a steel inserted. Roof is double apex (it was originally a single garage with a second, later addition). Roof will be left open with exposed rafters as adding a ceiling will, I think, make it too closed-in. All walls will be insulated as will the exposed roof.
What I haven’t a clue about is what do I need to do with the electrics. There is a dedicated consumer board already in situ, so power won’t be a problem, but is there anything else I need to consider (number of sockets, placement, schumann issues, pyramids, matter and anti-matter, etc.
A better solution would be a high level air handling/heat pump unit. This would provide heating in winter and cooling in summer to the entire space. Simple refrigerant pipework would connect it to an external condensor unit.
