Budget Subwoofer FAQs
What are the hardest hitting subs on the market?
The hardest hitting subs on the market currently is the Planet Audio AC10D ten inch automobile subwoofer. The specs are insane, with a max power output of 1500 W and 750 w RMS. The AC10D subwoofer offers the best chest thumping bass thanks to its foam surround and propylene coil.
Do 10 or 12 inch subs hit harder?
With the right amount of power the 10 inch sub will definitely sound more crisp and hit harder because the cone surface area produces more sound pressure. The 12 inch subwoofer however can sound deeper.
How much does a decent subwoofer cost?
Be prepared to spend around $200 if you want a high-quality subwoofer that is average sized. This price point will include the subwoofer speaker and amplifier. If you have a more compact car you can easily find smaller subwoofers for less that still sound good.
What hits harder 2ohm or 4ohm?
2ohm subwoofers are louder than 4ohm because subwoofers with lower electrical resistance produce a louder sound. Keep in mind though that the 2ohm may be louder but sound quality may be reduced because of the power consumption.
Are Dayton subwoofers any good?
The company, Dayton Audio is great and the four box subwoofers they make have some of the best specs and design which are backed up by their many positive reviews. If you’re on a budget but still want a powered subwoofer that is worth every penny then you can’t go wrong with a Dayton subwoofer.
