What To Look For Before Buying?
When looking for the best 15 inch subwoofer, some factors MUST come into play to ensure you get the most suitable model for your unique needs.
These factors include…
For any given audio system, more power equates to more fun. For subwoofers, more power means more boom!
That said, the power rating should be the first thing you check when looking for the perfect 15-inch sub for your home theater or car.
You'll usually see two power values: peak power and RMS power (both expressed in Watts).
We advise you to focus on the RMS power rating as it shows you the sub's continuous power handling capability—making it more realistic than peak power rating.
So, how much power should you get?
As we've just stated above, Bigger is always better when it comes to power. BUT if you want to enjoy quality, seamless sound, we suggest that you match the sub power against your amp's output.
Another crucial thing to consider when looking for a 15 inch sub is its frequency range.
You should understand that you're looking for a subwoofer because it produces bass. And bass is the same as low-frequency output.
Any model that features lower frequency should, therefore, have the ability to breathe out the bass you need in your car or home.
The sensitivity of a given subwoofer is indicated in decibels (dB) and suggests a sub's ability to produce sound at a specific power level.
If you plan to power the new sub with a low powered stereo, then we advise you to go for a sub with a higher sensitivity rating as it requires less to perform.
On the other hand, high-powered audio systems function well with subs with low sensitivity ratings.
The best 15 inch subs are widely spread across the price spectrum. We suggest that you come up with a reasonable budget to help you narrow down your options for an easier shopping experience.
And when setting your budget, remember this:
Most subs under $100 price range are affordable, so you should set your budget around this range if you're on a tight budget. Most models here have average build quality and will offer you basic performance.
Some of the best performing models usually lie in the $100 to $200 price range. These products have greater build quality as well as a bassline. They'll surely give you what you're looking for—deeper low tones with no distortion.
If you've got money to spend, you can go above the $250 mark and enjoy solid/premium build qualities, ability to withstand MAX. volume without distortion, and the ultimate sound quality.
Frequently Asked Questions
1. What's the hardest hitting 15 inch subwoofer?
There's no single best 15 subwoofer that we can recommend to you since various models are designed differently.
If you want to experience the deepest possible notes, we advise you to look for a large 15-inch sub which comes designed for use in a sealed box. This is the ideal enclosure type for powerful bass.
Other factors that contribute to the depth of bass produced include sufficient wattage, incredibly low frequency response ratings, and size (larger subs can play deeper than smaller models).
2. Do I need an audio amp to power my new 15-inch subwoofer?
Yes, you'll need an amp to push up your new sub to produce quality, deep bass.
Your factory stereo might not be able to power the new sub on its own, making the amp a necessity.
3. How much power do I need for my 15-inch sub?
The amount of power you need to run your sub will depend on the model you buy.
Check the RMS rating to get a clue on the sub's power needs.
Remember RMS means "continuous power handling ability," which simply means the amount of power your new sub will need to run consistently.
So, be sure to check the sub's RMS power rating and check it against your amp's power rating.
4. Can I put my sub in the trunk and still enjoy deep bass?
Absolutely! You can mount in your vehicle trunk and still get to enjoy deep bass. This is because the bass can easily travel through the materials separating your passenger compartment from the trunk.
However, keep in mind that you might not enjoy quality bass if your car trunk is sealed/soundproofed.
If you believe that you're missing out on the deep tones because of your seatback and/or the rear deck material blocking the waves, consider punching several holes in the rear deck and then cover it with any acoustically transparent material.
5. square vs triangular vs round subwoofers: which one is better?
None of these three subwoofer shapes is "best" since different users have varying preferences.
That said, the square and triangular have got the looks, so they'll suit your needs if you want something eye-pleasing. Moreover, these woofers are known to reproduce bass extremely well.
If space is an issue in your car, you might consider getting a triangular sub as it can easily fit in tight places compared to the box subs.
All in all, the traditional round subwoofers tend to produce bass more accurately.
6. Should I power my sub with a mono or multi-channel amp?
Mono amps are a great choice for powering your 15-inch sub as they feature high power-to-heat ratio and exceptional efficiency, which is exactly what you need for power-hungry low frequency signals.
However, keep in mind that most mono channel amplifiers come designed to run at 2 ohms, and some run at 1ohm stable. This is unlike the multichannel amps which are made to work with 4ohm loads.
Keep this KEY difference between the two amplifiers types in mind when choosing the right amp to power your sub.
7. What does dual voice coil in a sub mean?
A subwoofer with dual voice coils means it has two separate voice coils, each bearing its own connection. This is an excellent feature as it gives you more flexibility in system wiring compared to the standard subs.
You can choose to wire a dual voice coil sub in independent, parallel, or series configurations—enabling you to power you to wire your sub as per your system design or preferences.
The best 15 inch subwoofer is a good investment if you want to fill your car or home with deeper, louder, and more aggressive bass.
However, you should be careful when shopping for these bigger subs as a good number of them are poorly engineered and tend to produce low tones clouded with distortions.
In this guide, we have provided you with some of the best 15 inch subwoofers that are expertly engineered to output deep, chest-pounding tones while keeping the distortions to a minimum.
