    Power nd db

    Turner,

    Thanks, this suggests that I can match the power of my horns with 36W of amplification and hence 500W into 4 Ohms, I think this is 300W or so into 8 Ohms, should be adequate.

    Of course those calculations don't account for room acoustics, YMMV. Your house is Victorian era, are the inner walls brick construction?

    Also, are there any special instructions for placement of your horns?

    Horn placement

    Turner, Hi

    The horns are approximately 70 cm from the back wall and about 55 cm from the side walls, they seem to have a sweet spot which is bets found by experimentation where they engage with the room, the inner walls are brick and likely to be the same when I move
