What do you expect will happen? What is not good about it now? Maybe it is something else like the crossover?

What's your motivation for having two midranges ? Do you need more SPL ?

Regards

I dont want 2 midrange....It was if I was going to add in the picture of the cabinets they have one 10" speaker per side was going to add one more per side for total of 2 on each side 10".
Or instead of using 10" being 2 on each side use 8" speakers 2 on each side....poss.
thanks...

So the question was one 10" midrange in the cabinet or add one more for 2- 10" midrange speakers per side for total of 4- 10" mids OR poss use 8" mids being 2 on each side total
of 4 - 8" mids. Not that Im going to jack the midranges up in volume,but a poss a enhance presence of midrange...value. Kind of like "More Cowbell" in the mix......
I do like volume is a factor in my quest for more Virgil Dontia.......drums.

I have also thought of using a midrange horn or ESS Heil with the midrange for what I would call the smooth sound of a midrange 10"speaker combind with the Mid. horn or ESS Heil as Midrange with the 10" speaker as a union of those 2 midrange items each giving its own finger print on the combined two midrange sounds, being 10" speaker and mid horn together.

2x10" per side does not seem like a good idea. Comb filtering is going to hurt you, at least at the top of the midrange. I have seen it done on line array speakers with 2x8" and a horn in the middle. You'll need to be careful about crossover points and such.

2x10" works just fine:

But does need a fairly low crossover point. I went for around 1kHz with these, which is where the 90x40 HF horn starts to lose its pattern. By having the midbass drivers arranged in this way, the narrow-ish vertical pattern is maintained to a lower frequency. Handy for live sound - if you get them reasonably high, they don't kill the people at the front.


Gray, why do you feel that an extra midrange is needed?
