Subwoofer enclosures? Why?
This is a very complicated and overly discussed topic. For over 80 years manufacturers
and hobbyists have discussed, debated the virtues of having enclosures, vented (ported)
versus sealed versus bandpass versus transmission lines.
It is beyond the scope of this tech tip to discuss all the virtues (pros and cons) of each.
We will keep the discussion to sealed versus vented as these are the 2 most commonly
used enclosures for car audio applications.
Remember there are 2 types of energy in car audio. Electrical, which ISNT free, and acoustical – which is
FREE. Typically no one complains to their retailer/installer that they got TOO MUCH BASS! Everyone
complains about not getting enough!!! So lets FIX that! Design and build better subwoofer enclosures.
SEALED: Advantages
1. Simple to build, no real thinking involved.
Hard to screw up
2. Best phase and time response.
SEALED: Disadvantages
1. Loose typically 3 - 6dB of output versus
vented
2. You’ll need 6dB more power to get to the
same point in output as a vented enclosure.
Or like going from a 500 watt amplifier to
a 2,000 watt amplifier. And the subsequent
additional current draw. 500 watts is about
58 amperes, versus 2,000 watts which is 233
amperes (full power current draw)
