Welcome Four Kneez! Big move to loudspeakers from headphones. The room is critical, avoid small, square, uninsulated, and hopefully undedicated. Loudspeakers should fit the room. Audition carefully, take notes, limit yourself to 3 or 4 loudspeakers per day, take your time. And do yourself a favor and look into active monitors.
Welcome back Guy. It's supposed to be 96F next week here in Michigan, so hope you'll be happy. My son is giving up on Phoenix, AZ as becoming too much like Los Angles (supposed to reach 110-115F there today) and moving to Wisconsin.
