The18 Sub Passive VENTED – Ascendo

THE18 SUB PASSIVE VENTED adalah subwoofer 18 inci dari ASCENDO yang dirancang untuk menghadirkan bass yang dalam, bertenaga, dan bebas distorsi dengan harga yang lebih terjangkau. Melalui desain vented enclosure (boks berventilasi) dan rekayasa presisi, subwoofer ini menawarkan keseimbangan sempurna antara ekstensi frekuensi rendah, hentakan (punch) yang kuat, dan tingkat akurasi tinggi untuk kebutuhan home theater maupun komersial.

Fitur Utama:

  • Ekstensi Bass Maksimal: Disetel secara hati-hati pada frekuensi 25 Hz dengan kemampuan ekstensi di dalam ruangan (in-room) hingga mencapai 20 Hz, menghasilkan tingkat tekanan suara (SPL) yang luar biasa.

  • Komponen Rekayasa Tingkat Tinggi: Dibangun dengan voice coil 4 inci tahan suhu tinggi untuk keandalan jangka panjang, suspensi linier, sistem motor magnetik yang tangguh, serta rangka cor (cast frame) untuk menghilangkan resonansi.

  • Desain Boks Kokoh & Bebas Resonansi: Dilengkapi enclosure berventilasi dengan penguatan ekstra (heavily braced) yang secara efektif meminimalkan resonansi yang tidak diinginkan, menjaga kejernihan dan presisi suara.

  • Profil Desain Fleksibel (Shallow Design): Desain bodi yang ramping memungkinkan fleksibilitas tingkat tinggi untuk penempatan di belakang layar, dinding samping, atau bagian belakang ruangan.

  • Kebutuhan Daya Terukur: Dirancang secara optimal untuk bekerja dengan amplifier berdaya 1000 hingga 2000 W pada 4 ohm (sangat disarankan dipadukan dengan amplifier subwoofer ASCENDO untuk performa tak tertandingi).

  • Kualitas Terverifikasi: Memiliki metrik performa yang telah diverifikasi oleh pengujian pihak ketiga, memberikan rasa aman dan jaminan kualitas untuk setiap instalasi.
