How to Choose Best 6.5 Inch Subwoofer – Buying guide

As you have gone through the reviews of some best subwoofers, and you are now almost ready to shop. But in our opinion, this isn’t enough. Stay here for a few minutes more, as we are going to discuss some important specifications, which make a sub best from hundreds of options. 

The buying guide will help you compare the best 6.5 inches subwoofers to buy the excellent one. 

  • Power

The topmost factor to consider is power, as your subwoofer is small, and therefore, it becomes your priority to pick the high-powered subwoofer. Typically you will find two types of power ratings; RMS and Peak power. 

You have to consider RMS watts more than Peak power. As the RMS rating determines how much power your subwoofer can handle for long hours continuously. On the other hand, peak power watts define the ability to handle short bursts. 

However, the short bursts are temporary. Therefore, RMS watts are your priority as this is something that you need to check keenly. 

  • Strong overall built

You will be investing hard-earned money to fulfill your music desires. It is recommended not to compromise with the durability factor. The durability of a subwoofer depends on several things. 

First of all, its voice coils should be made with anodized aluminum wires, capable of handling higher temperature situations. However, dual voice coils are ideal in this term. 

Secondly, the cone needs to be built with rigid but lightweight material as well. The rigid material addition will ensure durability, and if it is lightweight, you won’t encounter voice distortion ever. 

Furthermore, the surround also needs to be sturdy and strong enough. Moreover, a strong and high magnetic powered magnet also affects the durability terms. 

  • Air-Circulation 

 Your small subwoofer needs proper air circulation to keep the components cool, especially when running for long hours. To check the air-circulation capability, you have to consider the basket venting. 

If your subwoofer has a large basket for venting, it means it is capable of circulating air to each component. It also affects the durability terms of a subwoofer. 

  • Mounting Depth

If you are looking for a 6.5-inch subwoofer, then maybe your major concern is to install it in a shorter space. If we are right, then do not go with a high mounting depth speaker. 

However, low mounting depth ensures the small size and easy installation as well. Moreover, if the speaker is mounted near the box, then it can produce better sound quality. 

  • Frequency

The frequency range only matters when you are buying more than one speaker. Probably, you will need two or more subs to get shaking sounds from your small-sized subwoofers. 

In this term, the frequency becomes a priority. A higher frequency means higher sound quality. However, high frequency also prevents sound distortion. 

  • Easy Installation

Easy installation is the second biggest reason to go for a 6.5-inch sub. The terminals for attaching wires need to be located in the right position. 

However, wireless subwoofers are the most easier device to install. But if you are ready to bear the wire headache, then you must look for a speaker, which doesn’t hold useless wires or wire length.
