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 3/4″ MDF, be glued and secured with nails or screws. Add bracing to each of the larger unsupported panels. Your enclosure’s 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.
Calculating volume
Measure the available space for the enclosure and using the formula (H x W x L divided by 1728) determine the appropriate measurements needed in order to achieve the desired cubic enclosure. If two facing sides are of uneven lengths add them together and divide by two.
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-APD 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.
Sealed enclosure
This type of enclosure is classic and the simplest to build among most installers. The box volume will directly impact the performance of the subwoofer, it is important to make sure the enclosure is properly sealed. Use some type of sealant on the seams as this will ensure a solid construction and prevent air leaks. Larger enclosures will provide a flatter response and deeper bass where as a smaller box will provide a generally higher output for greater SPL. All sealed enclosure designs should be filled to 50% with loose ply-fill. The use of poly-fill will slightly decrease efficiency but will deepen and extend the low frequency.
Primary advantages
-
Small enclosure
-
Good low frequency extension and control
-
Simple to build
-
Excellent for sound quality
Calculating volume
Measure the available space for the enclosure and using the formula (H x W
x L divided by 1728) determine the appropriate measurements needed in order to
achieve the desired cubic enclosure. If two facing sides are of uneven lengths
add them together and divide by two.
The enclosure recommendations listed are external dimensions using 3/4″ thick
wood. If you use 5/8″ material subtract 1/4″ from each dimension, we strongly
recommend not use material less than 5/8″.
*Note the enclosures listed in the manual account for the driver displacements.
Recommended Sealed Enclosure
Vented enclosure
This type of enclosure is the installer’s top choice for high performance SPL
levels and requires a deeper understanding in order to achieve maximum
efficiency. The most notable difference between the sealed and vented
enclosure is the port, this port is used to tune the enclosure. Larger boxes
tend to be easy to tune to lower frequencies while medium and small boxes are
easier to tune to higher frequencies. The vented design is less linear in
response than the sealed but with noticeably more output at the tuning
frequency.
Primary advantages
- Low distortion around port
- High output for SPL
- Tuning frequency can easily adjust depending on length of port
Port displacement
All of the cubic ft. provided in this manual includes the speaker displacement. For vented enclosures the port displacement must be calculated and added to your internal volume. If using 3/4″ MDF wood add the thickness of the wood 1.5″ to the H and the W, next use the outer dimension of the port so (H+ 1.5) x (W+ 1.5) x L=(result). Use the (result) and divide it by 1728, this new result is then added to your internal cubic enclosure.
Recommended Ported Enclosure
Note:
If you’re going to bend the port at 90°, you will need to add 1/2 of the port
width to the length! **See the example we have provided for you below:
Example :
- (Fig. 1)
- Wport=3″
- Hport= 1 O”
- Lport=20″
(Fig. 2)
Since Wport is 3″ you need to add l.5″(1/2 of Wport) to Lport.
This means that Ll=D1+1.5″, L2=D2+1.5″.
Lport=Ll +L2
Always measure Ll and L2 down the center to get an accurate measurement!
