Building an enclosure
When building an enclosure, the walls should be as rigid as possible and not
flex.
Flexing of the enclosure can drastically decrease your subwoofers performance.
It is recommended that Enclosures be built using l” MDF, be glued and secured
with nails or screws. Add bracing to each of the larger unsupported panels.
Your enclosures construction has a significant bearing on how well your
subwoofers perform. When designing your enclosure keep in mind and account for
wood thickness, port and woofer displacement.
Seale,/: 2.25-5.5 Jt3
Porte,/: 4.25-7.5 Jt 3
Use 12.5″”‘2 of port area per cubic foot of internal volume in the enclosure.
This is about ideal for most daily installations. Surface area is the width of
the port multiplied by the height of the port.
Example – For a 2.0 ft3 enclosure, 25″”‘2 of port surface area is recommended.
With 12.5″”‘2 of port area per cubic foot, you can use the following lengths
to get one of the desired tuning frequencies.
16″ = 40hz
20″ = 36hz
25″ = 33hz
32″ = 30hz
With any of our subwoofers, we recommend that you tune no higher than 38 hz
for daily music use.
Wiring subwoofers
When designing your system it is important to achieve a good power match between your subwoofer amplifier and the subwoofers capability. RMS power should be considered as a regular method of driving the subwoofer, make use of the power without drastically overdriving the amplifier. Amplifiers cannot read how many subwoofers are in the connection, they normally read the final impedance or otherwise known as ohms. It is important to properly match your amplifiers normal operating impedance with right subwoofer configuration.
Wiring options
The TXX-BDC4 series of subwoofers are available with dual 4 Ohms voice coils. Both coils must be connected to a source of amplification. A dual 4 Ohms woofer can be configured in parallel to provide a 2 Ohm load. A dual 4 Ohms woofer can be also configured in series to provide a 8 Ohms load. The terminal with the red markings is the positive while the black terminals represent the negative.
