IMHO, you'll need something larger than a metre or so for decent

Depends how much MF and LF response he wants... there is a
relationship between dish diameter and the lowest frequency that it
will focus effectively. They do have a lot of "suck" and directivity
though at the expense of frequency response. Do a UK google search on
"sound mirrors" for real parabs...

Last time I rigged a parab was at Headingly on a test match to get the
whack of leather on willow, there where also mics buried in the pitch
and cabled back, these had to be delayed.
