Small bass Horn?

[bhg41088]

I was wanting to build a small, low power (50-100 watt) bass horn using an 6 1/2, 8, or 10 inch sub. This will be used for my computer sub, and as an experiment in horn loading drivers. Any help would be nice, Driver recommendations, documented projects, anything. Thanks.

i would say "Small bass Horn " is an oxymoron.

I'm with Till. The driver may be small, but the size of the horn is still determined by the wavelength of frequency at cut off.

That is to say, a 40 Hz wavelength is about 28 ft. If you figure 1/4 wavelength for the horn with corner loading, you still end up with 7 ft of ever-expanding length wrapped up (folded) into a box which must have a mouth circumference to fit the same frequency/wavelength (some fudging here). So, while the driver may be small, the box is not.

Might do a search on the recent thread here about the "Bose Cannon". Similar 1/4 wavelength concept again without the horn expansion. Or use a transmission line and add power.

by small, i mean, a reasonable size folded horn. I dont want something 12 feet tall and 6 feet wide. Just something small.

2 Tang band W8-740c . Properly loaded into a corner. Your long skinny horn could be ~1/2 Lab horn size. For a 30 Hz horn.

1) define small
2) state SPL needed
look at my site for an 8" design i used which is ~150litres.

How 'bout a 1/2 size A7 with an 8"

I just so happen to have 2 W8-740c's. Anyone have box designs?
