What are the reasons to not be considering building 3-way active speakers over purchasing 2-3x priced 3-way Passive speakers

Yo are not getting the point where these JBL/EV/QSC speakers be needing lot more additional cost than just that to run directly wired from AVR. That was my point. The price gonna go up. And even INR1,80,000 is already much higher than I was trying to limit. So yeah if I have to go that high I would simply spend on Paradigm Premier series. But as you see since the start of this thread I am trying to find alternate for Paradigm speakers which cost much less and not as much as them. That is the point.
Paradigm?

lol
Yes. But am unable to decide between these and SB Acoustic Aluminum drivers.
do you like the sound of aluminum drivers? or paper?
It's a decent enough mid-bass speaker but ragged in the top end so not so easy to work with is my guestimate.
Many decades ago somebody I respected gave me a decent rule of thumb for designing my first set of 3-way speakers.
First make sure that the crossover fell outside the critical communications band of 300 to 3000 Hertz and the wider the range here the better/easier. Secondly make sure all the drivers had smooth responses at least an octave above and below the crossover point and that the woofer had to/ should be at least twice as big as the chosen midrange if possible.
That last rule of thumb is very flexible but works well if you think about 8 inch woofers with a 4inch midrange. It also worked for me using a 15" woofer with an 8" midrange.
I think you should go and read some books on speaker design before wasting any more of your time and possible wasting a lot of money
OP, please read this comment.
again and again, until you understand

you are clearly a beginner. you need to build something simple first. you will fail otherwise

Not all aluminum and paper drivers are made same right. So won't be picking it based on material. But based on which gonna perform better in detail retrieval and accuracy. Not all drivers are good at doing that. But heard positive of those SB Acoustic and Peerless Tymphany drivers.

But now am also considering a bit different route with BMD coaxial driver for high and midrange and possibly 8" or 10" woofer. Have to decide that yet.

you should at least get a known desing.
going blind, without experience, is uselessly complicated when you dont have a ton of experience under your belt.
why not use a DIY design of a proven diy designer?

Because the 3-way designs the drivers from proven and tested sources are not easy to get or are very expensive. So in either case it is not working out unless you can help me find a 3-way speaker design for which I can source in drivers or at a very reasonable price. I am unable to find such designs.

Please if you have some good design sources you wanna share. That would be really helpful.

cant you have the drivers shipped to you?

if not, what manufacturer you have access to?

edit: you can buy Faital from india. problem solved for bass! get a faital 15" pro driver in a BR 150L cabs.
now you just need to find a midrange driver you like, then find the type of tweeter you want

i wouldnt get a coaxial if I were you. they often need modifications both physical and xo wise to sound the best. they require a bit of experience. generally, for a noob, i dont think going coaxial is a good suggestion.

The price with shipping and taxes takes it way up. Like almost double of what it costs. So hard to consider it.

I do plan to pair them with SUBs. So is that big woofer really needed. That will take up hie lot space with wide enclosure design.

if your asking if a 15" is necessary for excellent bass if you ask me, id say yes. you either need dual 12" or a 15" at the very least. if you ask 10 others here, youll likely get vastly different answers

imo, if you want real bass with real dynamics, you need a minimum of a cone area. Adding subs is adding another layer of complexity.

since your a noob, you want simplicity. id go classic 3-way (big bass driver, with 5 or 6 '' mids and tweeter). id avoid coaxial, subs, ect

Going digital XO is probably your best solution here since it will give you a good understanding of different type of filtrs, how they affect the sound, ect. you could fail completely going passive, while going digital will assure you to finish with a well measuring speaker.

Let us know exactly which manufacturer is affordable for you? someone suggested you can get Faital in india...
 
I know you are trying to help me out by steering me to start and take it slow. With 2-way design and then work up. But see that is not an option for me at this point. I have to get on this project. I know very well that it is more complex than a simple 2-way design. But have to get on it and get it working. You guys helped me come this far. No looking back and reconsidering stuff.....

Why is it that you "must" have 3-way and "can't" go back to 2-way, not even to learn ?

I am kinda stubborn with a reason. Reason being there are many really good 2-way speakers for really low budget. No point me working on one even to learn as that will end up being not much better than really cheap ones. So. Would rather work on what I actually plan to have. And am bit not much by any means stubborn.

Oh, so theres many speakers that can beat Tannoy westminster or Canterburry for cheap? please let me know which exactly 😉
 
cause he's convinced himself he needs a 3 way. with subs to boost.

going with a big 2 way, say JBL 2226h with a horn crossed at 1khz with a passive xo in a 150L cab would be the simplest most proven design.
Hey if not going for 3-way and stuff. Would have actually avoided the DIY route completely. Would have settled for 2-way speakers and towers. But if you think 3-way have no pros over even a really good 2-way then you are mistaken. See poor 3-way design will suffer against a decent 2-way. But a decent 3-way gonna be even better than really good 2-way. Let it be in dispersion, sound stage or even imaging.

where did I said that 3 way is not better?
Ive mentionned many times already that going 2 way is beneficial in your situation since you are a noob.
3 way adds a complexity that you seem to dismiss for their supposed theoritical superioirty. in practice, often 2 way or even fullrange, for noobs is recommended cause they are much simpler to design succesfully. sucessfully... anyone can build a 3 way speaker. very few can build a successful one. hence going with a proven design in your case is the ONLY way if you want to go big for the first try and not fail. if you cant due to cost, many here recommend to you simpler design to get your feet wet. the experience youll learn after building your first speaker is invaluable. it might make you learn things about speakers youve never thought before, ect.

Yes. But forget the complexity part. I will have to deal with it. It is tough but it is worth the effort.

As I said I am ready to taken on a proven design but needs to be 3-way. I never said I will not take on a proven and tested design did I.
I will list the brands of drivers which I can source in. But have to say that not all drivers from the brands may be available. But yes will provide you with the list.

yes, a list would be great!

if you absolutely will not defer from going 3 way. fine. then, i recommend not going passive crossover for your first attempt. get a good digital crossover.

what is your room size and intended SPL?

Yes was definitely planning to go Active route as I know the complexity of building a passive 3-way crossover. That is what my title describes right.

18' x 20' x 10' seating will be 12' from front wall so rear wall will be 6' away.
