Which is better sealed boxes or ported

The end result is much deeper in-room extension than the quasi-anechoic rated low frequency response would otherwise suggest. With each successively deeper octave, cone excursion quadruples in a sealed subwoofer in order to maintain the same sound pressure level as a ported subwoofer. In addition, the equalization required to tailor and optimize the quasi-anechoic frequency response consumes amplifier power.

In a ported subwoofer design, a relatively large enclosure size is required in order to achieve both a deep system tuning frequency and sufficient port area to minimize chuffing artifacts aka port noise at high drive levels. A larger enclosure also greatly enhances system efficiency in the deeper octaves, with no need for additional EQ boost to achieve naturally deep bass extension.

This makes the larger ported SVS subs a natural choice for system applications with larger rooms where less room gain is present and reference-level playback levels, particularly on demanding Blu-ray action and sci-fi movies with demanding LFE tracks. Simply put, if you want to most room-energizing, gut-punching, floor-trembling cinematic experience possible, a ported subwoofer will deliver greater dynamic output at the lowest frequencies vs.

One of the most persistent myths in the audio industry is that ported subwoofers perform poorly on music. This reputation was largely earned by the public suffering through decades of small, ported boom boxes so common in 5.

At SVS, we call these imposter subs. SVS ported subwoofers have a flat frequency response, low distortion, excellent bandwidth linearity and a very deep tuning frequency typically 20 Hz or deeper.

The deep system tuning frequency shifts port-induced phase rotation and associated group delay below the typical music bandwidth, where we are relatively insensitive to it. The graph shows group delay curves for a variable tune ported subwoofer in 20 Hz ported, 16 Hz ported and Sealed operating modes.

Note the group delay curves for all three modes are coincident from Hz Hz which covers the typical music bandwidth , only diverging at the very deepest frequencies. Both sealed and ported alignments have strengths and advantages, and which type of subwoofer is best for a given application depends on several variables. All of these factor into the selection process.

In the end, both types of subwoofers can deliver an outstanding, no-compromise listening experience on both music and movies, provided the selected subwoofer model is a great match to the specific listening preferences and room.

Reference performance hits an all-time low with the Pro Series. I was thinking about drilling small ports into the box for each speaker. Question is size of the hole. I know 3" will be do much, I was thinking along the lines of 1. I listen to rock and Rap and instrumental bass Trance, Electro, Trap etc.

Would a smaller port hole be of benefit for my needs given the smaller air volume I have to work with? It's simple - a subwoofer gives you more bass, reproducing lower frequencies that your other speakers can't deal with. And subs aren't just for "bassheads. At Crutchfield, we love to see that look of surprise and joy on someone's face the first time they hear a sub in their vehicle! There are three different types of subs: component subs, sub boxes, and powered subs. A component sub is the speaker by itself, and you'll need a box and an amp to complete the package.

A subwoofer box is an enclosure with a component sub installed. A powered sub is an enclosure that houses an amplifier and a sub - an all-in-one bass package. A sealed enclosure tends to sound tighter and more accurate. A ported or vented enclosure adds a small opening that allows bass to escape for more output with a slight loss of accuracy.

A bandpass box is a combination of those two designs for even more output. More questions? See our Subwoofer Buying Guide. First, figure out where a sub will fit. If you have limited space, consider a small powered sub.

You'll be surprised how much bass you'll get. Also, what are your plans for your sound system? A small sub and amp will work great for adding some bass to a factory radio, but if you have plans to expand your system, go with the biggest sub that'll fit. Yes, all subs need an amplifier.

Some subs even come with an amp built-in powered subs , so you don't have to match the sub to the amp. If you prefer to customize your system, make sure to get an amp that's powerful enough for your sub. The more bass you want, the more power you'll need. Our subwoofer shopping guide will help you determine which kind of subwoofer and bass system you need, to get the sound you want.

Dual voice coil subwoofers are a popular choice among car audio enthusiasts who want more flexibility in wiring their sound systems. What does the gain control do anyway? This article describes how to adjust your amplifier so that your subwoofer sounds just the way you want it to.

This restriction in movement actually prevents the sub from over-extending itself, clarifying individual notes and providing a tighter, more accurate bass response for your music. This causes the rear wave to dissipate within the enclosure, causing a loss in the overall thundering quality of your bass response, and requiring more electrical power to recreate that thunderous bass sound.

In other words, you may need a higher power amplifier to drive the sub and compensate for the drop in efficiency that is built into the sealed subwoofer enclosure. Without a doubt, ported subwoofer enclosures are your go-to option for that block-shaking, bombastic bass tone that packs a lot more reverberance and punch than a sealed enclosure.

However, even with this simple difference in design, configuring a ported subwoofer enclosure can be difficult in terms of establishing balanced, clear sound output similar to that of a sealed enclosure. The secret to building a good ported box is to size the box and the vent in the correct proportion to each other. The vent needs to be placed in such a way that it re-directs sound from the back of the enclosure to augment the bass being thrown from the front of the cone, boosting the overall output significantly.

This means you can run a couple inch subs like the JL on the picture, one of my favorites of a moderately powerful external amp and still get the bone-shaking, skull-rattling sound you are looking for. More bass, plus less drain on the electrical system equals fewer dead car batteries and more bang for your buck.

Open enclosures can maintain a lower operating temperature thanks to the increased airflow, putting less strain on the surface of the cone while it is cranking out that atomic low-end sound.

Okay, so now you know the specific differences between sealed enclosures and ported enclosures for subwoofers, and the vastly different methods they reproduce low frequency sound.. Take a second to let that all settle in. Both enclosure types offer benefits and drawbacks, that much should be clear, and they definitely will improve the efficiency and overall sound of your car stereo regardless.

There are two very distinctive methods for deciding which type of enclosure is best for you and your car stereos needs: ported enclosures bring the boom and the volume; sealed boxes bring the clarity and the quality. If you are interesting in shaking the ground as you pass by , you need to invest in some ported sub enclosures. Universal Kits. Complete Car Kits. Wiring Kits. Bass Knobs. RCA Cables.

It really comes down to what type of sound that you like most. But what kind of high quality sound do you want? Do you want tight and accurate or do you want kick, bass and knocking power? Sealed boxes are smaller, more compact than ported boxers and because of that it makes the sounds easier to listen to while you drive. You can enjoy your audio or video sound quality without the constant reverberation from bigger subwoofer boxes that bring more power into their soundwaves.

Sealed subwoofer boxes do have the capability of producing stronger bass sounds, but you need to add more power to the woofer in order to do that. You might as well go ahead and invest in a ported subwoofer box if you want strong bass sounds that can kick. Ported subwoofer boxes are recommended to people who want bass, power and kicking power that enhances their entire sound system; ported subwoofers are exactly what you need for that to happen.

Ported boxes are much larger than sealed ones and are more efficient when it comes to the power. A poorly tuned subwoofer will make your sound muddy and hard to listen to, especially for a ported subwoofer. As we mentioned earlier, there is no right answer to which subwoofer enclosure is better, sealed or ported. What type of music you listen to and do you have enough room in your car to install a sealed or ported subwoofer enclosure. If you enjoy songs that bring laid-back and relaxing vibes to your drive then the sealed subwoofer would be the best choice because it delivers a concentrated and more focused sound quality to your speakers, which can make for a more serene drive in your vehicle.

If you like Jazz, Country or any type of easy-listening genre of music then a sealed enclosure would be your best option.
