It comes in two impedance options—$3\\ \\Omega$ and $4\\ \\Omega$—so it works with popular Class-D amplifier boards, like the PAM8403 and TPA3116, which are often used in DIY Bluetooth speaker builds.\u003c\/p\u003e\n\u003cp\u003eThe speaker uses a rubber surround that allows the cone to move further, giving you a strong bass response without hitting the mechanical limit. Its lightweight paper-composite diaphragm keeps range vocals clean and captures high-frequency details with precision. With mounting ear tabs, it’s easy to install and replace in damaged units across portable wireless speakers, micro soundbars, and smart home hubs.\u003c\/p\u003e\n\u003ch2 data-path-to-node=\"8\"\u003eKey Features\u003c\/h2\u003e\n\u003cp data-v-12b11f84=\"\"\u003eBalanced full-range acoustic output covers a frequency band from $100\\text{Hz}$ to $20\\text{kHz}$. I find that balanced, full-range acoustic output reduces the need for extra tweeters or crossovers in mini speaker setups.\u003c\/p\u003e\n\u003cp data-v-12b11f84=\"\"\u003eHigh-Excursion Rubber Surround lets the cone move, which gives punchier low-frequency bass notes than stiff foam surrounds. I notice that the high-excursion rubber surround produces a bass response.\u003c\/p\u003e\n\u003cp data-v-12b11f84=\"\"\u003eLow-Impedance Efficiency ($3\\ \\Omega \/ 4\\ \\Omega$) is made for low‑voltage Class‑D amplifier circuits that run on a $3.7\\text{V}$ to $5\\text{V}$ battery. I see that low-impedance efficiency maximizes wattage output.\u003c\/p\u003e\n\u003cp data-v-12b11f84=\"\"\u003eThe durable stamped metal basket keeps the voice coil aligned and stops it from bending when you install the speaker.
