Good evening, friends.
I have developed a tower speaker, a central speaker
and a tower speaker for surround sound.
The tower speakers are 3-way speakers, the central
speaker is 2-way speakers. I would like to hear your comments.
First, what do you think of the speaker layout? Your experience
is important to me. At this stage, I want to improve the speaker
layout I have developed. From the speaker layout to the internal
crossover.
The speaker is spectacular, but it is time to improve what I can.
I am counting on your opinion.

You should watch videos from Danny Ritchie from GR Research.  I would get rid of the front surround and make it flush with rounded corners to cut down on front baffle reflections as a place to start.

Let me see if I understand your comment:
you say, on the front, leave the corner of the box
rounded, different from how it is today.
is that it?

Why multiple midrange and bass drivers in the towers?

When the description says good for auto or professional use are they speaking of PA work as professional?

What is the goals for these speakers? 

What are the projected prices?

Where's the specifications for the tweeter and woofers?

Ported or sealed design?

1) Why multiple midrange and bass drivers in the towers?


hI, MISTER JLM

R: About mids> I tested one 8-ohm mid and two 4-ohm mid in series. I found the
two mids in series to be sonically better. I tested male and female voices, and the
sound was better with two of them. That's why I included them in the box.
I understood that using two in series would have a higher SPL and lower distortion.
Feel free to comment. I'm already studying the use of just one mid with higher power.
I've already acquired two 8-ohm mids from B&C for testing. I didn't use a duct in the
mid chamber, so the mids are in a sealed box.

SUB WOOFER: I used two of them to increase the final SPL. I tested using just one
and two connected to separate chambers. I found that acoustically it was
 better with two of them. Each one has 350W.

=========================================

2) When the description says good for auto or professional use
are they speaking of PA work as professional?

R - Professional speakers are speakers designed for environments where sound quality
and faithful audio reproduction are important. They are used in recording studios, theaters,
 concert halls, clubs, and in portable sound systems.

3) What is the goals for these speakers?

R- It is a 3-way box, treble, mid and bass

Tuiter  110 db

4)  What are the projected prices?

R - JBL TUITER ST 450 -  400,00 reais (6 Brazilian dollars = 67 dollars)

Value of each MEDIUM: 200,00 reais (6 Brazilian dollars = 34 dollars)

10-inch subwoofer 370,00 reais (6 Brazilian dollars = 64 dollars)
