Maybe drinks vibrating off the table and onto the cones!

Now that I have an air filtration system I wouldn't feel as apprehensive about machining (routing, especially) MDF. Without the AFS, I've had far too much MDF dust in my shop for my comfort. I must say I like the way it routs.

I think part of the problem is that architects and designers are often evaluated based on pictures of the final product. As such, sound just doesn't factor in.
I'd agree as you can't "hear" the pictures in their portfolio so all that probably matters is that it looks good to the next prospective client! Funny thing is architects are pretty technical folks however when I would ask for specs of the drivers they would be using so I could design the cabinet properly some would act like I was speaking a foreign language. I would then try to explain that size/shape/placement/room acoustics etc matters but they didn't seem to care or would sometimes seem offended that you questioned their design capabilities.

In any case all wood material is going to have a resonant frequency somewhere (the denser/stronger the material the higher the frequency) however as long as that frequency doesn't fall within the range of frequencies played by the driver(s) in that cabinet or is only in a dogs audible range it won't be a big deal (except maybe to the dog) and if it does fall within your audible range there are many ways to reduce the effect on the sound. Almost forgot, placement and room acoustics will have a large effect on how any speaker cabinet sounds.

Anyone remember when Linn claimed having a telephone in one's sound room would effect the sound? I believe it was Ivor himself that said that.

"Machina Dinamica", or something to that effect?
Laughable at best, but certainly entertaining.

Marv, anybody that uses the term "drivers" instead of "speakers", must be an audiophile, or a reformed audiophile. haha

I'm guilty of being a former audiophile myself. :) I reached my personal pinnacle of being a audiophile-with-discrentionary-income in and around 1985. I still have nearly every item purchased in that time and it all works well. The only piece that needed a couple of repairs is an Apt-Holman preamp (too many mechanical switch issues) and one electronics failure. Thankfully a local repair shop was up to the task of getting it back on its feet.

How about the guy that sold some kind of ceramic loops on a stand so you could keep your wires off of the floor to prevent induced noise or something crazy like that!

I highly resemble that remark and I would have used the term "transducers" but I have a hard time spelling that sometimes!

Actually the term "audiophile" seems kind of snobbish to me so I prefer "audio fanatic" as I just like the sound of music and was fortunate enough to parlay my cabinetmaking with a love of music into a side business building speaker cabinets (I mostly do mobile audio stuff online these days).

I too still have most of the first "good" system I ever purchased back in 1977 which consisted of a pair of Infinity Column ll towers, a Dual turntable (traded that for a PC sander many years ago!) and Kenwood amp, tuner and cassette. I rebuilt the woofers (4 10's) years ago due to the surrounds rotting and have never heard anything since then that sounded so much better in the mirdange that I just had to have them so I keep using these (the 4" paper cone midrange is very natural sounding).

Oh yeah. Lots of charlatans in the audio biz. Like directional interconnect wires or raising the speaker wires off the ground to avoid the "Noise Floor". Lots of meaningless marketing as well - Oxygen free metal. Not to mention the placebo effect is raised to an art form. Lot in common with wine tasting.
@Marv - those architects ARE speaking a different language - it's called a "design language". Only visuals in that...

Anyone remember the Elcassette format, or machines? I vividly remember seeing the Sony unit at Pacific Stereo, and for a while I wanted one, but quickly realized the format was DOA. A couple years later I ended up with a Nakamichi Dragon which is awesome and still works great.

I don't remember that format but I bought my gear from Pacific Stereo in Monterey Ca!
