i'm looking forward to those becoming more prevalent. you can
actually buy them now, can't you? i seem to remember it was possible
to order individual units, a year ago.

yeah i've experienced these types of speakers: they're absolute hell
and cause tinitis. the level of distortion is immense, and most of
the energy goes into high frequency (hence the distortion). to get
good sound quality, most important is to have an amplifier stage
that's more powerful than the speaker (and use its lower power range),
and to get good dynamic range you need the largest air box you can
get.
the alternative: i do know someone who made a ceramic phased array.
got perfect acoustics using DSPs. amazing. anyway. distraction.
too expensive. pity.

means needing software which supports two sound devices. bit awkward
but doable, especially anti-theft you'd end up writing that as
separate software anyway.

yes at least one expresscard (USB only)
> Rechargeable AA battery’s for the battery pack would be good?
yes. modular battery pack, definitely. this is important for
air-freight shipping these days. i.e.... you can't ship lithium by
air, it has to go by sea. if the product's shipped separately of its
batteries, and it's possible to sell packs which take AA then at least
you can stock _something_.

good idea.
