Guys, Don,
I built a bass horn about the size of the LAB, but using the lesser 10" driver pair from MCM, a design that John Sheerin worked up. The idea was to keep costs down using a $37.60 driver. The drivers are rated just under 90 dB and 175 watts. In the present smallish room it will roll off fairly rapidly below 40Hz, but I use a DT300 plate amp from Adire rated at 300 watts 4 ohm. I have never had it to 9 o'clock on the volume yet because SPL reaches 120 dB at the mouth first. Just hellish loud with very little power. This horn and John's bass horn both work even better on concrete. With heavy low bass material at say 30 Hz, it feels like you are in a airliner with faulty cabin pressure - a physical pressure in both ear canals - so pressurized is the room.Normally a big believer in headroom, I really can't imagine needing more than 100 watts in a horn of this type for residential use. An auditorium may need the big power, but not in my house.
