Best Competition Subwoofers To Buy In 2019 [ Updated List ]

Car audio competitions are a huge deal. These are contests that pit the participating vehicles’ stereo and speaker systems against one another to determine who has the best sound pressure level (SPL) and sound quality. Now, a car’s audio system is made up of several different parts such as the radio, the main speakers, the amplifier and a subwoofer or two. Each part plays a key role in the entire set-up. In this article, we are going to focus specifically on subwoofers. We are going to introduce you to some of the best car competition subwoofers currently up for grabs.

What is a competition subwoofer ?

A competition subwoofer is a high-power high-output bass loudspeaker. It is larger and heavier that regular subwoofers. It is used in auto competition settings, although it can also be used in family cars for everyday use.

Strictly speaking though, there is no such category as ‘competition subwoofer’, although some brands do market their products as competition grade to indicate the extreme power handling capabilities of the devices. Having said that, there are a few defining attributes of competition subwoofers. They are discussed below.

First, competition subs are high-power gadgets. The average RMS power handling ability of a competition subwoofer is around 1000 watts which is not very common for a normal car subwoofer.

Second, they are larger and way heavier than standard-issue subwoofers. Most weigh upwards of 20 kg.

Third, they have large voice coils, often with diameters more than 2.5 inches.

Fourth, they have Xmas excursions of 1 inch or more.

Fifth, they have large spiders. The minimum size is 7 inches.

Sixth, their cones are made of composite or other extremely rigid and strong material.

Seventh, competition subwoofers like the HCCA Series and the Solo-X Series come with re-cone kits for fixing the sub in case of damage which is quite common in competitions.

To conclude, we can say that the most striking features of a competition subwoofer are its high power handling capacity and large excursion. A comp subwoofer needs to be put in a box. The dimensions of the box are equally important as it both supplements the sub’s performance and helps to keep it cool.

Competition Subwoofer Buying Guide :

Here are the top points you need to keep in mind while choosing a competition-level subwoofer for your vehicle.

Power Handling

The first thing you need to consider is the power handling of the device, which is denoted by the peak power and RMS or continuous power handling. Peak power indicates the maximum amount of voltage the sub can handle at a time, often in short bursts and never over prolonged periods. RMS power is the average amount of voltage the sub can handle continuously for a long period. Hence, RMS power is a more realistic assessment of the power capacity of a gadget. While selecting a subwoofer, make sure you note the RMS power of the device. Do not be swayed by a lofty max power figure. The RMS output is a more reliable and close-to-home number.

Of course, to get the best out of your sub, you will have to hook it to an amplifier and as such the power rating of the amplifier is also as important. For optimal bass reproduction, the amp should be able to produce around 75% to 150% of the sub’s power.

Size

The performance of a subwoofer is dependent on its size. The amount of air a subwoofer pushes out is directly proportional to its size. Large subs generate more SPL (SPL) than smaller ones. But, a large sub needs a larger enclosure. It is heavier, less portable and occupies more room. It consumes more power which means you will be refilling your tank more often. So, before you lock down your money, we advise you to note the space available in your car, and let that decide the size of your subwoofer.

Competition subwoofers come in 2 sizes, 12-inch and 15-inch. A 12-inch sub is not small, but it also won’t hog all the space in your trunk. If you want heart-thumping bass, but need to make sure you have space left for other things in the boot, 12-inch is the ideal subwoofer size. It is portable, easy to install and works great in dual setups. If you want bass that’s much more palpable, and don’t mind letting it have some extra space in your trunk, you should go for a 15-inch sub.

Cost

The cost of a subwoofer is another critical factor. Cost is often not a true indicator of a sub’s sound quality. Sometimes, a moderately priced subwoofer can generate impressive amounts of bass you wouldn’t have thought possible in its price range. So, before you make up your mind, listen carefully to the sound put out by the device and then take a pick.

A subwoofer is not a self-sufficient device. It needs a compatible enclosure, a good amplifier and solid wiring to work flawlessly. In other words, you need to pay equal attention to these things for the final set-up to deliver as expected. In fact, a properly wired low-priced sub matched with the right amp and mounted to the right enclosure can give you better output than a high-end sub.

However, if you want longevity and premium materials, you might have to shell out a few extra dollars. Expensive subwoofers use tougher building materials to make their cones, surrounds and baskets. They also have larger and more durable voice coils and spiders. As a result, the gadgets are less likely to suffer damage when operating at max power capacity for sustained periods.
