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.
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.
recovering from typhoid so i cant travel for a few days. if i dont email you in a week remind me. [email protected]. 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.
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.
