Bigass bass horns using conventional sub drivers?

Spasticteapot · 2nd November 2010, 10:40 PM

Most folks building horn subs are generally building them for playing music, not infrasonics. As a result, while very efficient and capable of impressively low distortion, they generally start to run out of puff around 30-35hz.

I've also seen a few subs based around more conventional low-efficiency high-Xmax drivers, similar to the Table Tuba. Has anyone built a sub like this?

Also, on a related note, does anyone have any thoughts on the use of high-pass filters? I'm new to horns, and it would appear that playing any material below a certain point will cause huge subwoofer excursions with no output. As such behavior could potentially damage the driver, a steep high-pass filter seems in order, but I haven't seen much of anything along these lines.

Hi spasticteapot,

Take a look at mwmkravchenko's Trio-12 FLH thread:

TRIO 12 Front loaded Horn Subwoofer

and, soho54 did some very nice work in this thread:

Can this work

In properly designed FLHs the horn loses its effectiveness below the design cut-off, but the sealed rear chamber protects the driver from over-excursion. They should be better off than transmission lines, tapped horns or bass-reflex enclosures in that respect.

Above all, make lots of models in Hornresp, it will tell you what a particular speaker is capable of, including the excursion.

Regards,
