Everything You Need To Know From Professional Installers
Just like the popular proverb ‘You can’t have your cake and eat it’, you cannot have excellent sub-bass levels in your vehicle unless you are ready to sacrifice money and space. We have settled on this point for years now and though many companies made attempts to overcome such hurdles, most of them did not get much success.
But there is one company that took the challenge and came out with flying colors. The Japanese-born electro-wizard Alpine decided to take the genre of pre built enclosure back to the drawing board. Alpine had to struggle with the limitation of physical space when designing its enclosure.
Eventually, They came up with an 8-inch subwoofer loaded into a ported enclosure designed to let you add deep and accurate bass to the sound system without having to sacrifice valuable vehicle space.
Today, we discuss what The Alpine SBR-S8-4 is and the features and benefits that make it rise above its competition.
The ported sub enclosure by Alpine gives you the bass your system was missing without occupying much space in the car. The enclosure is tuned by experts to deliver excellent bass with minimum power requirements.
Alpine has loaded the SBR-S8-4 with an 8-inch Type-R subwoofer known for its outstanding bass performance. The ported, superior-quality MDF enclosure is designed to be the ideal match for this subwoofer and guarantees maximum punch within a small profile.
The enclosure is made of strong timber and is finished intelligently in durable grey carpet both front and back and black laminate around the perimeter edge. The subwoofer driver is on the front face protected by a mesh grille finished in gloss black.
It comes at only 6 5/8” depth to be easily installed in a convertible trunk behind the seat of the cabin. Carpet protects the enclosure against scratches and nicks and metal grille protects the sub from flying objects and other hazards. Special design terminals allow using wires with large gauge.

The SBR-S8-4 makes use of the 8-inch subwoofer as in the Type-R component range to deliver high excursion with greater power handling. Such an innovative Type-R structure enables the motor to transform the output from an amplifier to a low bass that pleases.
Being compact and narrow, the enclosure can be mounted easily in any vehicle. The subwoofer system works greatly under or behind seat in a pickup truck, sedan or SUV.
The enclosure is ported to be able to play low without demanding high power requirements. A huge cross-section port combined with low tuning frequency allows it to play the lowest tones while maintaining excellent power handling and control.
A ported subwoofer enclosure lets the sound from the rear of the woofer cone to travel and join the sound coming from the front to enhance the tone and loudness.
Ported subwoofer systems hit so hard and deep because the air flowing in and out of port generate an audio effect resembling that created by blowing across a bottle’s mouth. Such tone adds and strengthens the note played by the cone.
Sleek laminate and superior-quality carpeting give SBR-S8-4 interesting look. It is constructed from the highest-quality materials. Structural components are made of high-quality MDF and it is braced internally to add to the durability and stiffness.
A port does not have to be straight. Alpine used a smart design of wrapping around to save space and keep the unit compact. The opening is flared port helping prevent the audible huffing with the air going in and out. Slanted exit port construction also serves the same purpose.
RMS handling power of 350 watts makes the subwoofer enclosure compatible with a variety of amplifiers, both mono and multiple channels. Whether you connect it to subwoofer channel on Alpine MRX-V60 or to the bridged channels on Alpine MRX-F30, you always get a low-bass performance.
Air induction through five pairs of dual-vertical intake ports handles cooling. The powerful cooling system allows the unit to handle more than 300 watts without any fear.
