Choosing a Subwoofer Box – Sealed Enclosures

When improving your car stereo system, you’ll want to choose an enclosure to maximize the woofers performance. There are three main subwoofer enclosure types: Sealed, Ported/Vented and Bandpass. Each has advantages and disadvantages in efficiency, size, distortion, cost, and power handling. Sonic Electronix carries a wide variety of enclosures but specifically I am going to tell you a little bit about sealed enclosures.

While sealed enclosures are usually smaller than other types of sub boxes, they don’t allow any air to escape from the box. Woofers installed in sealed enclosures increase the power requirements and make it more difficult for the sub to bottom out. When the subs movement is restricted, it provides tighter bass and better sound accuracy,  giving you less boom and more punch.

Just a couple cons about the sealed enclosure is the decrease in efficiency (loudness) and sound reproduction due to the airwaves being unable to escape as it would in ported or bandpass enclosures. Also, the tightly sealed design doesn’t allow the motor structure to cool down as quickly, causing possible damage to your subwoofer more quickly.

Keep in mind, if the enclosure you have is smaller than the recommended size, the sound will be tighter but more amplifier power will be required to push it. If the sub box is too large, the sound will be distorted and sound horrible.

When choosing the correct subwoofer enclosure you’ll want think about what design and size you want. The design you desire whether it be sealed, ported or a bandpass, should be based on your music styles choices.

Sony XS-LB10S Shallow-Mount Loaded Enclosure

Sony XS-LB10S

One of the coolest aspects of my job is that I somehow get paid to take a first-hand look at some of the top products in the car audio industry. Sweet gig, right? When I found out my latest assignment was to evaluate the Sony XS-LB10S, I couldn’t have been more thrilled. As a truck owner, enclosed subwoofer boxes are an interest of mine since they can fit right under the seat and save cargo space. After testing it on-site, I came away impressed with the sound quality and bass emitted from this loaded enclosure.

After connecting an amplifier to power the sub and a music source to play some tunes, I was able to observe this subwoofer’s strengths and weaknesses. First off, I was amazed at its level of bass considering its shallow-design. The cone excursion flexed rhythmically and did not miss a beat. The sound check showed that the Sony XS-LB10S subwoofer does not emit muddy bass or poor sound quality. Distortion only occurred when I tried to push it to its furthest limits.

The grill and sub cone look great, though I found myself lamenting the fact that the two-bar grill design only partially covers the subwoofer. This would be a problem if I mounted this sub box in the back of my truck since I typically toss supplies in the back seat without regard for my seats/audio components. The front firing design hits hard with the beat and noticeably pushes air around. It would look great behind or below your seats, or in the trunk those of you who own a sedan.

The XS-LB10S sub exceeded my expectations and is definitely worth a look if you are in the market for a loaded subwoofer enclosure. The shallow-mount sealed enclosure design is ideal for vehicles with limited space. Whether you install it behind your seats or underneath them, this sealed box setup is the perfect piece for adding bass without wasting space. At 330 watts RMS you get a whole lot of bass for your buck!
