4-way speakers

glazarou · 10th August 2006, 08:12 PM

i want to buy 4 drivers for a 4-way speaker(tweter,midrange,woofer and subwoofer).to buy them it 's easy but i don't know the right analogia between the drivers.

e.g.
if i want the hole speaker has max input 100watts,how watts must be each driver?the impedance must be the same for each driver?

Hi
Yikes, where to start on such a gigantic subject. OK..Advice is to build a 3-way and add a Sub as needed. Can't you find a 3-way speaker you like first. Or better yet find a 3-way completed project?
What size room and amps do you have? On&on.

I would say if your hopes are very high, and it sounds like it, then you will be disappointed designing your own 3-way, with out any experience
And believe me, I know - I have just finished a 3-way that in some areas outperforms the biggest ATC Aniversary(cost around 15000 pound), and the ATC driven by top of the line NAIM is a VERY good performer - I think it has taken me more than 5 years till now, and I actually dont know if I am finished yet

So, at the moment I think of making a more simple and easy going speaker with 4 or 6 x CSS FR125s pr side, and a super tweeter on top - maybe it will be a DIPOLE
Should be an easy task, I hope - and complemented with big 15" woofer, could be JBL 2235H, I suppose it will really shine, but I will have to test with a single driver first.

But to answer your question - sensitivity is the first and hardest factor to consider, as to which drivers are needed

Yea if you're new to speaker design I wouldn't go for a three way. I'm close to finishing my 3 way design but since I have no measuring equipment i have to rely on simulations. You could go for an established project then add a sub (or two) later on as needed.

Why not just build this?
