Custom Built Subwoofer Enclosures

 Sub Woofers are typically used in a vehicle to reproduce sounds the average car audio system is not designed to do.  These sounds are called Sub-basswhich are frequencies below 90 hertz.  A couple of examples of this type of sound would be from a bass guitar or a kick drum (largest drum in the set that stands on its side on the floor).  To have a sub woofer installed in your vehicle you will need to have it mounted in a specific type of box or enclosure. So whether you want a subwoofer to enhance the quality of your vehicles sound system when you’re listening to your Classical, Jazz or Classic Rock or you want to focus more on the bass when you’re listening to Rap, Heavy Metal or Techno, R.T. Grim Electronics can build a system to satisfy your needs. Enclosure Styles Sealed Enclosures The most common and versatile type of enclosure is sealed. This style enclosure is ideal for any application where space is going to be an issue.  They also have the advantage over vented enclosures in terms of overall sound clarity providing a smooth deep bass. A sealed subwoofer box will deliver a tight, clean and accurate bass response and have a flat frequency response curve. In general a sealed box will be for listeners looking for sound quality driven system that is clean across the entire frequency band. Vented Enclosures A vented enclosure just means the enclosure has a hole in it to let air escape. You know that guy you can hear from 2 blocks away? Well he is likely using a vented box.  Vented boxes are more efficient than their sealed counterparts, since they channel sound waves from the front and rear of the cone into the listening environment.  This gives it a much more boomy effect with less accurate bass response. With vented enclosures, you do not need as much power coming out of your system since the lack of an airtight box allows your subwoofer to move much more freely and the vents allowing you to hear every bit of sound produced by your subwoofer Types of Enclosures Standard Pre-fabricated These enclosures a typically rectangular in shape and are made to hold anywhere from 1 to 3 subwoofers.  They are made of MDF (medium density fiber board) and are covered in a material similar to what you typically see in a trunk of a vehicle.   Vehicle specific Pre-fabricated These enclosures are shaped specifically to fit in the vehicle they are designed for.  Ones that are used in trunk or rear hatch applications are designed to use the least amount of space and typically conform to the side or rear of the trunk.  Others are designed to fit in a vehicles cabin and typically mount under the seat or in the center console.  They usually hold 1or 2 subwoofers.  They are either made of MDF or a high density polyethylene resin.  We offer vehicle specific pre-fabricated subwoofer boxes in these brands.
