Things to Consider Before Buying

You should know that the larger the surface area of the cone, the more area it can disperse sound and the louder it will be. Larger subs, such as the 15-inch models are better for SPL systems. Basically, larger subs have larger motor structures.

So, you have to be really into larger woofers because they are heavier, bigger, and generally difficult to control. To make sure that you have better control of what the sub is outputting, you have to make sure that the sub has a good balance of output and punch.

What is the ideal power handling?

One of the most distinctive features of larger subwoofers is the power handling. These beasts have enormous power ratings. Most of them have rating in terms of thousands. 

  • You can find a model with 5000 watts peak power and 2000 watts RMS power.

You have to make sure that the RMS or continuous power is close to the power ratings of your amplifier. A 2500-watt amplifier will be able to power a subwoofer with a continuous power rating of 2000 watts. This ensures that your sub operates effectively.

How does a high-quality design look like?

The best 15-inch subwoofer design has to be radical and be able to offer you the clearest and loudest bass sound. For high performance and power handling, the subwoofer design must be based on superior bass technology.

What you will observe with larger subwoofers is the unique cone, surround, and design material. Unlike smaller subwoofer models(like 6.5 inch), 15-inch subs have a wider and deeper cone design. The surround is usually pushed towards the top.

The best design should have a well-built cone, such as an injection molded cone, which is the stiffest for distortion-free bass sound reproduction. The surround and the cone have to be made of high-quality materials that offer uniformity, linearity, flexibility, and excellent excursion.

One of the most recommended surround materials for larger speakers is Santoprene. This is a very flexible and durable surround material. Unlike other materials, Santoprene is highly tear-resistant. It prevents the surround from ripping under heavy usage.

Santoprene surrounds are known to be long-lasting. They can survive harsh environments without damage. You should not expect the surround to wear out and tear even if your car is usually exposed to sunlight most of the day.

Durability also depends on how the surround and cone are linked. Therefore, the best model should have a ribbed surround. This will give the woofer cone added strength and higher excursion. It also improves the linearity of the cone.

Is the subwoofer ergonomic and user-friendly?

You can get the best performance out of your subwoofer, if you can use it without any problems.  The best model should not be difficult to mount. In fact, the most thoughtful manufacturers will supply you with a manual that provides the necessary installation tips.

A 15-inch subwoofer with push-spring terminals is very resourceful, because they are very solid and secured compared to the conventional terminals. The spring part of the terminal will make installation easy.

The best model should have a very strong and well-built basket that is integrated with coil cooling and perimeter venting. The spider has to be incorporated with tinsel leads, which should be stitched and glued to the spider roll for reliable performance, reduced noise, and added strength.

A good 15-inch sub ought to have a progressive roll spider. This kind of tech keeps stress away from the glued connections of the spider landing. This feature also helps the subwoofer last longer, and improves on durability.

As far as voice coils are concerned, you have to consider a 15-inch subwoofer with dual voice coils, which are made of high-temp copper windings that are very much capable of handling extreme power levels for a long time without overheating.

The best voice coil structure should give you more wiring options when setting up your system. The most appropriate large subwoofer for shallow mounting ought to have a perimeter venting on the sides. This way, you can use a shallow enclosure without the risk of overheating.

The recommended enclosures for 15-inch subwoofers are large boxes. If at all possible, you should use a big ported box to achieve lower bass. You can always use a smaller sealed enclosure if you do not have enough space for a ported box.
