Review: A good choice for replacement of old 2.1 music system woofer.. - Its good. While ,I got 6ohm woofer, while it said it's 4ohm, but later found out that I needed 8ohm woofer. So as return was not an option, just used/fixed it on my creative a120 2.1 music system,and its better than my last/original woofer. I would say go for it, but do note that , the impedance may vary, so... Can't be sure about it, but anyways ,its a good product and value for money for its affordable price(rs342). . For some uneducated people, don't expect it to rumble in a large room, its made for small rooms and gives best bass performance only while sitting close to or sitting in a close/small-medium room.

I want to install two of these speakers on it. Will the sound be deep if I use 1 inch dia port?** A: Hi Sree, I love when somebody comes up with bang on specs. If you have 165 cubic inches of box, and I'm assuming a geometrically symmetrical box of 5.5inches all 3 sides, I would suggest a 1.5 inches air port so the subs fire from magnet side as well. No port or ineffective port will lead to one side/diaphragm/cone side firing only. Do leave me a review if you happy with your audio box. Tc... **Q: Can i use this for 100 watts 2.1home theatre board** A: Hello Abijith, I assume you have a circuit board for DIY purposes. That's good because, your options are open now as you have 100W Amplifier. You can use these 3 subwoofers as per your budget/choice for your 2.1 system. Fredo 4 inches subwoofer. Fredo 5.25" subwoofer or Fredo 6" subwoofer. I wish you all the best for your project. Tc.... **Q: I have tpa3110 30w amplifier , Can I use this subwoofer for voice,bass,music without require any other speaker?,I am planning to buy 4inch 4ohm 30w su** A: Along with LF (Low frequency) driver, it can be also used for Mid-Range driver. Frequency range from 30Hz to 12KHz can be reproduced easily. So yes, you get Full Range - Base, mid and treble out of this. Thanks. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best 2 in 1 application ....
