In my band we have 2 ways speakers, we play andean music,
panflutes, classic guitar, drum, just accoustic sound.

Acoustic drums or electronic drums?

I wonder if we buy 3 ways speaker is going to make any
difference.

Since no two different speakers sound alike, different
speakers are going to sound different.

The way that I understand is the we are not getting the
mid freq it all, the speakers we use has the horn and the
huge speaker about 18" diameter.

In theory its possible to cross a large horn and an 18"
driver in a somewhat sensible way. In practice it doesn't
seem to happen a lot because the horn has to be pretty large
for this to work.

Even if you sucessfully cross an 18" driver to a large horn,
its pretty much guaranteed that the resulting system will be
rather highly directive in the midrange. If the horn has
enough directionality to match up with the 18" driver, then
its going to have maybe 50-75 degree coverage above 800 Hz
which is narrow.

If the horn is too small, then you're going to have a
frequency response hole in the midrange most places but
right in front of the speaker system. Given that performers
usually stand to the side or behind the main speakers, they
are oging to have problems hearing the mid (and probably
high) frequencies.

Few years ago we used to perform with my 15" home stereo
speaker(ja ja) but the sound was great, we don't play
very loud, we play in private parties and festivals.

Home stereo speakers as a rule lack the robustness and
ability to generate loud noises that you need for most sound
reinforcement jobs.

15" happens to be about the largest speaker that is commonly
used in 2-way systems, and for many applications its on the
edge. 15" can work in a well-designed system if you don't
want a wide coverage area with just one speaker.

The speaker that we use now(2 ways) are JBL, I know that
are
very good speakers but maybe with should get other
speakers.

How many of these JBL 2-ways do you have?

What is the model number?

Anybody has any advice?

Other than the drums (if they are electronic) you don't have
much that would seem to need a ton of low frequency
response. The use of 18" speakers seems questionable
especially if you only have one speaker system.
