Thank you really so much Sudhir for your kind advice. I consider your this post as an encouragement.

Sometimes we face problem due to a slight inadvertent mistake in the PCB design posted on the internet . But your words really helped me to get rid of that concern.

Could you please tell me how you made the PCB ? I am a bit hesitant to use my old toner transfer method in this case as the board is large and fairly complex.

( Oh, I purchased 6 TLO74 Ics and sockets and some 1% metal resistors. And some other parts are already in my inventory. So wish me luck please )

Thank you so much Piersma for your reply.

I am using a two way setup from the ESP site. I definitely found an improvement using them over my passive network that I used earlier. No biased opinion here. So I decided to use a 3 way system mainly to learn, to experiment while DIY-ing is an added pleasure.

The links are really good. But unfortunately they have hardly any readymade PCB layout design to start with ( except the kit which is the best way to make a quick start). Perhaps I can design the layout myself but I am impatient right now
The last link has a very well thought out discussion on different aspects of using Xover as I can see.
So I sincerely do appreciate your post. Thank you again.

Hi,

Unfortunately standard L/R electrical crossovers are no short
cut to high quality loudspeaker design, they are too inflexible.

rgds, sreten.

Thank you for your reply Sreten.
I completely agree.
That's why I am in search of a tested PCB layout as I am not so skilled.

I talked to a PCB making company in my locality.

Hopefully I will get the PCB in a week or so.

I will keep everyone updated about my progress.

Thank you all .

Hi,

It is not about PCB's. It is about the ideal electrical transfer functions
looking nothing like any standard textbook electrical filters, used to
achieve with the drivers and box the correct acoustic responses.

Thank you sreten.

Could you please recommend some reading material in this regard so that I can understand it better?
I need them because my next work is to tune up my DIY Floorstanders. They sound very nice "by chance".
I need to know what more can I do to optimize their acoustic response.

Thank you for your feedback.
