Hi, I'm an swedish owner of a pair of Castle Windsor speakers. Castle isn't a widely spread speaker in Sweden. I miss manuals for them and I'm very eager to get the technical spec for this speaker. I can't find the Windsor at Castle's webpage and they don't reply to my E-mails. Basically I want to know the frequency response, especially how low they go, 50 40 30 Hz or what? I need that to be able to play well with my newly bought subwoofer. What is the lowest frequency it can play and when does it start to decrese in strength, where should I meet with my subwoofer? If someone have info on the tech-spec of this speaker please post! Thanks in advance! Sorry for the lack of correct english audio-terms.
