Hi, I´m from Argentina and here we don´t have many options to choose, regarding customs problems, economics issues and those stuff. So, I´m looking forward to build my own lite bass cabinets to pair with my GK MB200 lite class D head. I simulated a number of speakers within WinISD, and it seems I´ve found the ones that should do the job pretty well. The cyan plot... The yellow one looks interesting too because of the higher DBs between 50 and 250Hz... but that maybe will end in unbalanced and annoying volume differences between notes while playing. If someone can tell me about how accurate WinISD simulations are, and if my thoughts are in the right direction, I will appreciate a lot. Thanks a lot. Martin.
