I have an old pair of Boston Acoustic A60s in my bedroom and just picked up some Polk Monitor 30s. I am going to set up a stereo in my garage. Need some advice: semi-retire the A60s to the garage and put the Polks in the bedroom or just use the Monitor 30s in the garage?
I'd say keep the Boston's your main bedroom speaker but listen and decide. Or go listen to some new stuff at a decent dealer. Things have progressed in the last 28 years.
They wouldn't sound their best in an unheated garage in January at around -30C or so. Or looking at it more positively, perhaps it's the poor mans cryo treatment.
Nah, MDF is temp and humidity stable, that's why it's ubiquitous in cheap furniture and cabinets. Unless it gets wet - like sitting in a pool of water wet, it doesn't matter about any environmental changes. The stuff doesn't warp or change dimensions. I've got MDF in my garage that has sat there for years and is still spot on for dimensions and is as straight as the day I bought it.
Why do you think they use this stuff for cabinets in the first place? It's mostly glue!
And since it's mostly set up glue with wood chips embedded in it it's dimensionally stable. Any piece is the same as any other piece no matter the conditions. Put it in a jig and it's the same as the last 100 pieces and the same as the next 100 pieces.
If you don't care about beautiful wood grain, this stuff is perfect. This and waferboard but waferboard makes lousy speaker cabinets. Neither will hold a screw without some additional socket added but plywood, which you can screw directly into, suffers from dimensional instability to some degree and can warp slightly if exposed to high humidity for long periods, but Paul Klipsch liked it for holding screws without clamps. Made speaker assembly real easy and real cheap.
