Re: boxes for speakers
…MDF is better acoustically than the best plywood, but it's heavier and less durable.Baltic birch is much stronger and resistant to humidity. So if your speakers will be moved much or might be in humid environments, you might want to think about that. It…

Re: Building Speaker Cabinet
…
Sorry to butt in on your question, Reinhardt, but I'm curious about something. Would OSB be an okay alternative? I have so much of it around my house and I'd love to use it for something. I would want to sand it down some though, for aesthetic …

Use Baltic Birch
