Default Flush mounting anf cabinet geometry

My apologies if these basic questions have already been answered - my searches came up empty...

Two questions both relating to subwoofers
1. Does it matter whether the driver is flush mounted in the baffle as opposed to surface mounting? (I ask as I want to avoid a router purchase unless someone can sonically justify a flush mounted sub driver)

2. Assuming a vented or sealed enclosure - is there a disadvantage to simply using a cube? I know using the golden or other ratios with asymetrical bracing will create panels that will resonant at different frequencies (better) - but what about standing waves? I've read for a sub it doesn't matter since the wavelengths will be longer than any single dimension of the box (if this is true - why does this matter for room dimensions were a 1/4 wavelength can still cause dB peaks?)

2a. (ok I said only 2 questions - but this is related to 2.) - if I use the golden ratio - is it better to use the larger 2 dimensions for the baffle? (to minimise baffle step / diffraction loss anomalies) - or again - does this not mattter since the frequencies for a sub are lower than the practical width of any given baffle?

Your answers appreciated.

Thanks,
Dave.

Only on asthetic grounds, it will not affect the perfomance of the sub.

No, no problem at all

This is normally a problem at slightly higher frequencies, where room dimensions become a significant fraction of the wavelength.

Correct

Thanks for the clarification. I'll go for surface mounted for the first one.... Then if I've had fun with the first - I'll invest in more tools etc....

Sounds like the start of an addiction!

Dave.
