THE15 SUB PASSIVE VENTED – Ascendo

THE15 SUB PASSIVE VENTED adalah subwoofer 15 inci dari ASCENDO yang dirancang untuk menghadirkan bass yang dalam, bertenaga, dan bebas distorsi pada titik harga yang lebih terjangkau. Melalui rekayasa presisi dan desain vented enclosure (boks berventilasi), subwoofer ini menawarkan keseimbangan sempurna antara ekstensi frekuensi rendah, punch, dan akurasi untuk kebutuhan home theater maupun ruang komersial.

Fitur Utama:

  • Ekstensi Bass Terdalam: Disetel secara presisi pada frekuensi 27 Hz dengan kemampuan ekstensi di dalam ruangan (in-room) yang mencapai 20 Hz, memberikan pengalaman suara bioskop yang optimal dan SPL tertinggi.

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

  • Desain Boks Berventilasi & Kokoh: Dilengkapi enclosure berventilasi dengan penguatan ekstra (heavily braced) yang secara efektif meredam resonansi yang tidak diinginkan, sehingga kejernihan suara tetap terjaga.

  • Profil Desain Fleksibel (Shallow Design): Desain yang tidak terlalu tebal memungkinkan fleksibilitas tinggi dalam penempatan ruangan tanpa harus mengorbankan kualitas suara sedikit pun.

  • Kebutuhan Daya Terukur: Dioptimalkan untuk bekerja dengan amplifier berkekuatan 750 hingga 1500W pada 4 ohm (sangat disarankan menggunakan amplifier subwoofer ASCENDO untuk mencapai performa puncak).
