Hello All
I am doing a custom subwoofer build for one of our fellow Audioholics, lbolts20
We are working with a fairly limited budget but needed some good low end output for a moderately sized room. Ultimately we decided on JL Audio's 13W1v2-4 driver and a 300W rms Bash plate amplifier. We chose the driver due to it's good linearity, large surface area and, well, low cost. The driver models extremely well overall. The amplifier adequately suits the power needs of the driver as it will be a very efficient system.
The enclosure will be slot vented, tuned to about 21hz. (Extreme LF was not the biggest of concerns). It is 5.3 cu.ft. net and uses extensive bracing. We are using 32 sq. in. of port area to aid in output and extension. This results in vent air speed of approx 12 m/s. The enclosure will utilize a double front baffle and custom grille.
I will update as things progress.
Here are some first stage pics:
