Hi,
I on the way to get my crossovers out of the box and start a parts
upgrade.Maybe someone give me a suggestions.
The drivers are :
- ScanSpeak Revelator D2905/9900 tweeter
- old ScanSpeak 13M8621 paper midrange
- Morel MW266 paper woofer ( 4 Ohm )
Sealed box 60 liters plus 3 liters midrange chamber.
I think that orginal crossover it's design for 13M8640 not a 13M8621
and it's second order.Please see schematic.
Also 13M8621 it's not very popular but I have a datasheet.
Thanks for any help !!!
Joe
