SQ VS SPL
Whether you're trying to overfill your vehicle with bass, or you're building the perfect stereo system that produces high-quality music, there is the right setup for you. You may be aware of "SQ" or "SPL" terms. Understanding these common buzzwords will greatly help you decide on what kind of sound you are seeking. So, What's the difference between SQ and SPL? Read on to find out.
SPL ( Sound Pressure Level)
It refers to sound pressure level (the boom in the subwoofer), which means how loud a subwoofer can play. In regards to subwoofers, ported enclosures are usually favorable for SPL setups, simply because ported enclosures give you boomier and louder bass. This is due mainly to the ports pushing out more air and creating more pressure.
Additionally, ported enclosures are generally more efficient concerning the amplifier power necessary to make the subwoofers perform. Mounting your subwoofer(s) in a ported enclosure(s) allows you to use a smaller amplifier than you'd need with a comparable sealed enclosure.
Bigger subwoofers such as 15", 18" or multiple bigger subs are more common in SPL setups, as the more cone area the subwoofer has, the more air pressure it will produce. Sound Pressure Level is measured in decibels, which means, anyone can tell how loud your stereo system plays with an SPL meter.
In a perfect SPL setup, no part is neglected or omitted. Therefore, having high-quality speakers is a must. Also, consider metal tweeters with bright highs to complement the booming, heavy bass that the subwoofers produce and to prevent the bass from draining out the high frequencies.
SQ (Sound Quality)
SQ stands for sound quality. It's much more difficult (if not impossible) to measure than SPL. It simply means that the system has excellent sound staging and impressive tonal or musical accuracy. In SQ applications, sealed enclosures are ideal for subwoofers as they allow for tighter and more accurate bass responses.
Smaller subwoofers such as 10 and 12 inches are more commonly used for SQ applications. Sound quality can not be measured. However, a good subwoofer should be able to produce +/- 3 dB. It boils down to personal preference for the most part. So, if wish to have a well-balanced, accurate sound and want to hear the music as it was intended, go SQ.
Car Subwoofers – SPL or SQ? : Settling the Debate
Now that we’ve talked about both SPL and SQ systems, and the difference between the two, it’s time to decide which one is better; they both have their pros and cons - and there is always going to be haters on both sides of the fence, but you are the only one who can decide what's right for you.
So, what's the best: SPL or SQ? Well, this is not an easy question to answer, as everyone has different tastes and needs. Deciding between SPL and SQ is not an easy task because there are many variables to figure into the equation including vehicle type, enclosure, amplifier, subs ...etc. So, keep in mind that one is not necessarily better than the other, and it boils down to personal preference.
So is it useful to talk about SPL versus SQ subwoofers? Yes, I can't stress enough how important sound quality is. Who doesn't like clarity, accuracy, and well-balanced sound? Your ears will easily get tired of listening to distorted music. So, whether you are into SPL or not, Sound Quality is something to consider when you're looking for a car subwoofer.
These are just some of the best SPL competition subwoofers available on the market. If you’re looking for the best among the best, then you cannot go wrong with the aforementioned SPL subs.
They all pack incredible power and deliver high-quality performance at almost earth-shaking volumes. Pick your poison and start jamming out with these hard-hitting subs! Enjoy!
