Madisound, Seas 4.5woofer 2 way project estimate box vol.
2웨이 북셸프자작을 위한 용적 계산, 좋긴 하나 PC-fi를 위한 것치고는 최종 단가가 많이 상승할것 같다.
Natural rubber surround and handcoated paper cone with coated fabric dust cap,
reduce resonances and distortion.
Large magnet system and a symmetrical driving force accomplished through a
special coil winding technique for the voice coil gives an excellent linearity.
Very large magnet system provides a reasonable efficiency and a low Q.
Extremely stiff and stable injection moulded metal basket keeps the critical
components in perfect alignment.
Large windows in the basket both above and below the spider reduce sound reflexion, air flow noise and cavity resonance to a minimum.

이 우퍼를 WinISD이란 프로크램을 사용해서 가상 인클로저를 만들어 본 결과이다.
용적은 2.5Lt. 65.7Hz로 튜닝하고, 포트는 5mm x 100mm x 120mm 정도이다... 포트 높이를 5mm 로 만드는 것이 나의 목공 실력으로 정확하게 나올지 걱정은 된다...
암튼... 가상이니 만들어 봐야 알겠다...
그리고 이 유닛과 메칭할 만한 트위터도 알아봐야겠다...
