we play Acoustic drum, 2 JBL speakers I will find out the model #.
I don't use my 3 way home stereo speaker anymore because we busted the 15"
drives.

thanks everybody for the helps.



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.

..

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.
