6.5 Inch Subwoofer V3 Long Strokers 65W 4ohm for Bass Tube & Home Theatre

Best quality product and good voice, deep or clear bass

For the cost, it's really good. The local manufacturing is helping the brand to make it super cheap but the sound output is not bad by any means. Being only 6 inches, it can hardly be called a subwoofer but it's rather a 6inch woofer with good bass punch. The downside is, it can't be crossed over like a proper mid-woofer with a dome tweeter due to its low end extension. So this is best used with a small full range driver crossed around 200-250Hz. The other point to consider is its low sensitivity given the small cone (in terms of bass/subwoofer driver) so it's best paired with tiny full range drivers (2-2.5 inches) otherwise SPL matching would be a challenge. I have paired one unit of this with two 2 inch full range drivers for a 2.1 type boom box and it works great but I'm using a 2.1 amplifier card with seperate volume control for subwoofer channel so I can crank it high to match the full range drivers.

Very good Subwoofer speaker for home theater. You need to have speaker box to fit this subwoofer speaker.

I used this speaker in a 10-year-old Sony HT-GT1 soundbar, and the sound quality matches up to 90% of the original—so that's impressive! However, the speaker's diameter didn't match perfectly—it was slightly smaller. But as we say in India, we're known for jugaad, and I made it work! One thing to note: I ordered this assuming it was 4 ohms, but when I checked with a multimeter, it showed 5.5 ohms. That might be why it only matched 90% in sound. If the resistance had been around 3.7 to 4 ohms (as measured), it probably would have performed even better. Overall, it's a good product and a decent replacement if you're doing a repair or DIY upgrade.

This is my 4th purchase/return of this subwoofer. And this time It makes abnormal mechanical beating noise even at low volume, tested properly. Likely coil/suspension defect. Idk what to do. Thanks to amazon customer service I got refund this time too but I can't be sure can trust bia acoustic now? Ahhh that's all I can say.
