Single vs Dual Throats

[GEK]

I have a pair of 1505B's with 288-8K's along with 828 bass cabs and Hiraga crossover.

I have both single and dual throats, but have never tried the dual throats. I also have some 1:1.4 adapters and assorted other drivers.

Has anyone tried using dual 288's (say a pair of 288c's in parallel) vs the single driver?

Anyone tried the smaller drivers (say 802D's) using adapters instead of the 288's?

Thanks!

I would think the only reason you would want the double throat is double your input rating. I would guess the waveguide works best in single format.

I've had 1505 and 1005 horns w/ single and dual 288's on them. When you hook up two drivers you get better dispersion and more output. Works great in large rooms or outdoors.

Most people will say that a single 288 sounds better in a "home" style environment. Years ago I had eight 288's on 4 y-throats and 4 horns hooked up in my garage. Along w/ eight 515's and 4 210 cabinets. Think I had 11 or 12 288's at the time so I figured what the heck...... if nothing else it looks pretty intimidating. It sounded o.k., and was ready to go when I needed to use them for big parties.

If you've got 'em you might as well use 'em..........

I'll admit it's a little overkill for home use, but volume was never a problem.

A single driver already has to be turned down to reach a balanced level with an 828 box. Why boost the HF sensitivity even further by adding a second driver when you'll have to turn around and attenuate it down the same amount?

How much HF to use is a simple question of how much LF you are matching it to. The only exception is when long distances (stadiums, huge theaters, etc) are involved to compensate for the increasing HF loss over distance.

<font size="2" face="Verdana, Helvetica, sans-serif">Yes on the output, no on the dispersion. That's a function of the horn.

It will be louder off axis only because it's louder overall.

There are some response irregularities and phase issues, if you can't hear 'em don't worry about 'em.
