Mengenal karakteristik speaker

Adanya parameter Thiele-Small yang disingkat parameter TS telah membawa ke tahap standardisasi pada gambaran dan arti dari tingkah laku gerakan konus loudspeaker. Ini bermula saat A.N. Thiele (1961) dan R. Small (1973) mempublikasikan sebuah tulisan ilmiah di Jurnal AES (Audio Engineering Society) tentang bagaimana metoda mulai dari mengukur, memodelkan secara matematis dan menghitung kotak suara tertutup dan kotak suara dengan lubang (knalpot).
Memang saya juga tidak akan terlalu memusingkan kepala dengan model matematis yang sangat rumit tetapi bagaimana inti cerita agar kita bisa m
