Głośnik neodymowy SICA 10"- jaka obudowa i BR?

Witam wszystkich! Od jakiegoś czasu pojawiły się na rynku głośniki włoskiej firmy SICA. Jest to firma stosunkowo mało znana, lecz coraz więcej osób (w tym ja) przekonuje się co do wyrobów opartych na jej głośnikach m.in. paki basowe Box Electronics. Interesuje mnie zbudowanie małej paczki do gitary basowej do ćwiczeń o dobrych walorach brzmieniowych opartą o pojedyńczy głośnik 10"+tweeter. Jaką obudowę (w litrach) i bass reflex zastosować?
