A drop ceiling has a lot of advantages over drywall, and the only downside is more sound leaking to the floor above. But if sound isolation isn't an issue, a drop ceiling is great. The best tiles are made of rigid fiberglass. Years ago Armstrong sold high density rigid fiberglass tiles up to three inches thick, though I haven't seen those in a long time. But you don't really need that. Instead you can use thinner rigid fiberglass, with thick fluffy insulation on top where it's out of sight. The only problem then is that thick insulation above the tiles makes it more difficult and less pleasant to get to the wires, which is your whole point. So instead of covering the entire ceiling with insulation, you can leave a path for the wires. But you do want thick fiberglass around the perimeter because that's a corner that benefits from bass trapping. Home Depot sells 5/8-inch thick fiberglass tiles with a plastic surface. So here's what I'd do: I'd install those tiles as intended everywhere except the loudspeaker reflection points. For that cluster of 4-8 tiles I'd flip them over so the plastic is above the grid and the bare fiberglass is on the bottom exposed to the room. You can use spray glue or some other method to attach cloth to hide the exposed yellow fiberglass. Then put fluffy insulation as thick as possible above all the tiles, especially around the perimeter, but optionally leaving a few places free for your wires. --Ethan

Excellent, thanks John. Your input is always welcome here! Where's that thumbs-up smiley when you need it?

Welcome to The Audio Expert forum! The purpose of this forum is to discuss all aspects of audio science: recording, mixing, monitoring, how gear works and is tested and spec'd, hearing and perception, musical instrument physics, room acoustics and treatment, computers and software, music video production, hi-fi and home theater equipment and setup, and more. This forum serves partly as a support vehicle for my book The Audio Expert, though you don't have to own my book to participate! --Ethan

Welcome to the Audio Expert forum! This section focuses on acoustics and room treatment. Although I'm a principal at RealTraps, manufacturer of high-performance acoustic treatment, I gladly share my knowledge here. You do not need to be a customer of my company to participate, and I gladly help people with their DIY projects. However, I draw the line at advising customers of other treatment companies. As their customer you deserve their technical support and advice. If this is your first visit, please read the ACOUSTICS FAQ on my web site. This detailed article explains the basics of acoustic treatment, and answers the most common questions. The FAQ is admittedly quite a bit to read, but when you are done you will know a lot about room acoustics and treatment! You can also use the Table of Contents, or search the page in your web browser, to quickly find the topics discussed. There's also this much smaller version that's easier to read and understand: Acoustic BasicsThen if you have any follow-up questions you're welcome to post them here in the forum. A lot of visitors want to learn more about bass traps, and this is my most recent article: Bass Trap MythsHere's another recent article that everyone should read: Early ReflectionsThis article explains in detail how to measure a room: Room Measuring PrimerThis article compares room measuring microphones: Comparison of Ten Measuring MicrophonesThanks. --Ethan
