Hello!
I need some help with my DIY project. I have ss18W8545 and ss9300 drivers. I plan to build sealed box (18l). Problem is the crossover... Any good advices? 2000Hz ,2nd order... LSPcad?!
😕

My answer might be a little bit useless but I will say that crossover design is the hardest thing to do in speaker building. There is no magic rule to associate a type of driver/loudspeaker combination with a type of crossover. Each type of crossover has advantage and disadvantage. Part quality has also an influence.
I suggest you to search for crossover design in google and you will find a lot of useful information.
When I have time and enough parts, I try different crossover topology and I tweak the system until I get good measurements and a good sound.

i built a system using a 8546 and 9500. the box was a bit different though.
it was a hexagonal pyrimid with each side being 9" at the base.
I can send you those XO detials in case you are interested but remember the box was not a standard cuboid.

also let me know as the speakers are in anouther town and I have to visit my friend and open the speakers to check out the XO. I can do it if you are seriously interested.
Yes...
Yes.. I'm interest...so if u are able to check the cross over... send it to : b8_beat@hotmail.com

recovering from typhoid so i cant travel for a few days. if i dont email you in a week remind me. navin@vsnl.com. I am a bit senile so i forget.
also me+my family will be moving house so i can be better located between my 2 work places. presently I am near one and very far from the other. so this might take time.

Navin, if you have the oportunity to get the schematic, please post it here, I am curious.
Is it a simple network or it uses notch filter, L-Pad and other impedance equalization?

if i remember it correctly it is a simple netwrok. there is an Lapd using i think 4ohms series and 10 ohms parllel.
other than that the impedance correction is built into the network. it is a lot fo trial an error on site.
since we are DIY we have the advantage of using the XO to compensate for room abnormalities too. the cabinet as I mentioned earlier is not a cuboid but maybe this network will give you a good starting point.

There is a project using these drivers with the crossover at http://www.speakerbuilding.com/content/1021/ You may get some ideas from this project.
