angled in-ceiling? matinding challenge yan sir...di pa rin ba puwede at wala na bang ibang way kahit mounted man lang sa walls? the kids cant touch it too.
for me, may mga available naman na in-ceiling speakers sa market but the downside is that you will be spending a lot more as compared to the normal setup. and despite the high costs, its still doubtful kung magiging maganda ang sounds.
