Što je SPL subwoofer i zašto je bitan?
Što ako želite najdublji, urlajući i potresan bas iz svog audio sustava, čak i ako se odreknete neke kvalitete zvuka?
Pa, tome služi SPL subwoofer.
SPL ili subwooferi razine zvučnog tlaka dizajnirani su za proizvodnju ogromne količine basa. To čine pomicanjem velike količine zraka što stvara veliki zvučni tlak. Međutim, to je na štetu kvalitete zvuka. Kvaliteta zvuka bit će slaba, loše definirana i moguće oštetiti uho.
Moderni SPL subwooferi proizvode visok akustični tlak, što je ono što vam je potrebno za stvaranje dubokog, bučnog basa.
Danas objašnjavamo više o ovim specijaliziranim SPL wooferima, kako rade i još mnogo toga kako bismo vam pomogli da s njima dobijete najbolje iskustvo.
Što je SPL subwoofer?
'SPL' je skraćenica za razinu zvučnog tlaka i ovdje označava da su SPL subwooferi vrlo učinkoviti u stvaranju glasnog basa. Svi zvučnici proizvode određeni stupanj akustičnog tlaka.
Za koga su SQL subwooferi?
SPL subwooferi dizajnirani su za pojedince koji vole redovno slušati glazbu ili gledati videozapise s puno dubokog, snažnog basa. 
SPL subwooferi također su izvrsna opcija za pojedince koji žele imati mogućnost preciznog mjerenja performansi svojih zvučnika. Razinu zvučnog tlaka možete izmjeriti u decibelima (dB).
Neki se ljudi odlučuju za SQ subwoofere u pokušaju da dobiju zvuk savršene kvalitete. SQ označava kvalitetu zvuka. Mnogi ljudi, osobito oni koji ne žele dobiti glasan bas, kažu da nudi impresivnu kvalitetu. U nastavku objašnjavamo više o SQ naspram SPL subwooferima.
Unatoč tome, njihova učinkovitost ovisi o slušatelju u određenoj mjeri, uključujući percepciju vaših ušiju, udaljenost od zvučnika subwoofera i tako dalje.
Drugim riječima, nemate objektivan način za određivanje učinkovitosti SQ subwoofera. Dakle, odabir donosite ovisno o svom ukusu i preferencijama.
Očito, to nije slučaj sa SPL subwooferima, kao što ćemo detaljno vidjeti u nastavku.
Zvuče li SPL subs dobro?
U niskim frekvencijama, SPL sabvuferi su nedvojbeno učinkovitiji od lakših stožastih "SQ" sabvufera. Prstenovi za kratko spajanje, manje Le i druge mjere koriste se u SQ sabvuferima kako bi se smanjila distorzija. SPL subwoofer može zvučati fantastično, međutim, kvalitetu zvuka u konačnici određuje kućište, a ne subwoofer. Dakle, ako je kućište loše postavljeno, to će utjecati na kvalitetu zvuka koji izlazi iz sabvufera.
Kako izmjeriti SPL učinkovitost subwoofera
Možete točno izmjeriti učinkovitost svog SPL subwoofera slijedeći ove korake:
- Prikupite potrebne materijale
- Mjerač razine zvučnog tlaka: Većina njih su ručni uređaji, mobilni i lagani. Štoviše, proizvedeni su prema IEC 61672 i drugim relevantnim međunarodnim standardima. Možete koristiti mjerače klase 1 ili klase 2. Međutim, prva opcija daje preciznije rezultate.
- Mikrofon: Možete koristiti bilo koji bežični ili žičani mikrofon.
- Uključite svoj zvučni sustav: Naravno, zvuk bi trebao prolaziti kroz mikrofon prilikom mjerenja SPL.
- Približite svoj mjerač razine zvučnog tlaka SPL subwooferu: Mjerač će procijeniti zvuk koji ulazi kroz mikrofon i pretvoriti ga u vrijednosti i očitanja koja su lako razumljiva.
- Očitajte SPL sabvufera na mjeraču: Razine zvučnog tlaka koje SPL mjerač subwoofera obično prikazuje u rasponu od 20 dB do 140 dB. Unatoč tome, možete ga postaviti da mjeri niže ili više razine zvučnog tlaka od ovoga.
Mogu li dobiti više od ovoga? Da, možete. Ako želite, možete postaviti svoj SPL mjerač subwoofera da mjeri SPL tijekom dugog razdoblja ili u određenim intervalima.
Mjerač vam može biti koristan pri procjeni utjecaja zvuka koji sabvufer proizvodi na okoliš.
Podatke također možete pohraniti u internu memoriju i kasnije preuzeti informacije za detaljnu analizu. Na taj način dobivate objektivne informacije koje možete proučavati kako biste identificirali odgovarajuće mjere kontrole.
Kao što smo spomenuli na početku, ovo je privilegija koja drugim subwooferima nedostaje unatoč tome što također proizvode određeni akustični pritisak. Možete koristiti SPL mjerač za mjerenje njihove razine zvučnog tlaka, ali to se možda neće prevesti u poboljšanje jasnoće i vjernosti zvuka subwoofera.
Koji su najbolji SPL subwooferi?
Budući da su SPL subwooferi dizajnirani da vam pomognu u dobivanju dubokih basova, neki subwooferi nisu pogodni za SPL postavke. Najbolja opcija ovdje je prijenosno kućište.
Tipične primarne značajke prijenosnih kućišta su:
- Low distortion around port tuning
- Require little amp power
- Louder bass and more “boomy.”
- Large box
- Less accurate bass
- Port
Please note that the efficiency of ported enclosures results from their ability to drive a lot of air and creates tremendously intense acoustic pressure. By enabling air to flow freely through the port, SPL subwoofers can roar more.
Another alternative enclosure for an SPL subwoofer is the sealed box. We do not recommend it as it can’t create and sustain high sound pressure levels for an extended period.
However, it can work for someone who prefers ‘tight’ and focused bass. However, if you are for booming bass and maximum volume, the ported option suits your needs. Here are the key features of sealed enclosures that influence the subwoofer’s bass:
- Small box size
- Requires lots of power for louder bass
- Tighter and focused bass
In short, since a sealed box moderates the movement of the subwoofer’s diaphragm, the loudspeaker hardly thunders or roars. So, the choice is yours.
What Can Affect Your SPL Subwoofer’s Bass?
Size of Subwoofer
As we have seen, the type of your sub’s enclosure is essential, but you need to think seriously about the sub enclosure’s size. If you choose a small ported box, your SPL subwoofer will still likely perform below your expectations.
That explains why many SPL subs are very large. Many of them in the market today are 15 inches and 18 inches. Other users also have multiple SPL subwoofers.
With huge or multiple subwoofers, you get more cone area for creating more air pressure.
Type and Quality of Speakers and Tweeters
Your choice of speakers and tweeters play a vital role in the efficiency of SPL subwoofers. Of course, you need high-quality speakers.
Other than that, your subwoofer will make sure your neighbors can hear you if you are using metal tweeters. They are great at preventing the bass from draining our high audio frequencies.
Remember, deep bass can quickly destroy a weak tweeter cone or diaphragm.
Impedance Matching
Don’t forget that proper circuit operation relies heavily on the circuit’s ability to transfer signals efficiently.
So, if you choose the right SPL sub but fail to treat impedance correctly, it is highly likely that you will experience interruptions like reflections of signals and standing waves. Some users often incorrectly blame this on SPL subwoofers.
To avoid problems, you should ensure that your subwoofer’s impedance falls within that of your amplifier.
Best Music Genres For SQL Subwoofers
The best music genres for SQL subwoofers are those that are bass-heavy including rap, hip-hop, punk, techno, or other synthesized bass music.
SPL vs SQ Subwoofers
In addition to SQL subwoofers, there is another type of subwoofer on the market referred to as SQ or sound quality subwoofers.
As you may have guessed, SQ or sound quality subwoofers are designed to accurately reproduce the original source sound with the best sound quality. However, they won’t deliver the thundering bass that you can achieve from n SPL subwoofers.

What’s Better In An SPL Subwoofer a 12 or a 15?
The subject of whether 15-inch subwoofers have a better foundation than 12-inch subwoofers is difficult to answer because, to be honest, “better” is a subjective term. Because 15-inch subwoofers are bigger, and so are able to displace more air than 12-inch subwoofers, the smaller ones will sound crisper and sharper.
This makes the 12-inch subs greater for quality bass generation and able to produce amazing sound on multiple frequencies.

SPL Vs SQ Subwoofers
SQ Subwoofers
An SQ subwoofer is one that is built for sound quality. They are typically smaller in size and deliver less power compared to SPL subwoofers.
This does not however mean that they are lame in terms of power output. Although they may not be louder than SPL, they can still produce clean and clear bass sound.
SQ subwoofers perfectly support music genres that rely on precise bass foundation such as hip hop, EDM, and R&B. Also, the subs perform best with rap or electronic dance music. If you are not up to music with powerful bass, an SQ subwoofer is the best.
SPL Subwoofers
SPL subwoofers are subwoofers that are built for power and volume. They are larger in size and have more power than SQ subwoofers.
If you prefer to listen to music with some ground-braking bass, then n SPL subwoofer is the way to go. They can be very loud and are perfect choice for people who love music with powerful bass foundation such as rock and metal.

Zaključak
SPL subwoofers are perfect for those who want to fill their rooms with deep bass. However, you should opt for a sizeable ported enclosure, metal tweeters, and quality speakers to get the best overall quality. Given the high demand for current, you should also correctly match the impedance of the SPL subwoofer and amplifier.
That’s all. We hope you will put these tips into practice to be able to get your desired high-pitched sound.
