Hello bro, In this project I want to make a simple active lowpass filter for subwoofer using PT2351 chip.
This lowpass filter run in third order with -18dB /oct slope, it means that the resulting signal curve is very deep and only produces a small amount of mid-bass frequency.
The cut freq can be adjust by choosing the C1,C2 value according to the description displayed on the pcb.
This Third Order Subwoofer Lowpass Filter need 8-12V DC power supply.

Saya pernah nambahkan pengaturan freq di LPF, pakai 2 Capacitor paralel. Yg C1 terpasang sesuai skema, yg C2 nya diseri dg potensio 50k-100k. Kalau Pot nilai max, freq mendekati freq utk C1. Klo pot nilai minimum, freq mendekati freq utk nilai C1+C2.
Cara yg ga ideal, tp lumayan work kalau tdk critical dalam hal perhitungan freq yg presisi

Kalau untuk power besar uk speaker sobwofer 18 inc bisa mantap ngk mas,

Nb : tergantung komponen yg dipakai
