Try a larger port you would have to angle it to the left about 6-7" into the cabinet and you might be able to fit a 2" flared port but you would also Think that the port diameter is too small for a 6.5" subwoofer and there is a little bit of port noise with bass notes in the 30-40 Hz range at high levelsīut with music playing the port noise isn't noticeable (I only noticed it when I ran high level bass sweeps in that frequency range). The power handling for this type of design might actually be better at lower frequencies due to the lower port tuning The key with this type ofĭesign is to tune the port low enough so that there is little or no peak in the response at that frequency. The larger cabinet causes the response to rolloff higher in frequency but at a lower slope. Required for this driver but it produces an EBS (Extended Bass Shelf) alignment that lowers the f3 by using a larger cabinet with a lower The cabinet is a bit larger than typically The port tuning is 36 Hz and results in an f3 around 35 Hz. The Cerberus cabinet is an 11" cube with about 12 liters of internal volume once you factor in the space taken by the port and the amp. The ultimate multimedia subwoofer driver! The compact neodymium motor structure saves valuableĮnclosure space while also allowing closer-than-normal placement to CRT's. Good airflow around the coil to improve heat dissipation and reduce compression. Spider, and large 1-1/2" 4-layer voice coil ensure impressive bass performance and high power handling. The complete design can be built for around $100ĭrivers Tang Band W6-1139SC 6.5" SubwooferĪmazing bass in a compact package! This one-of-a-kind 6-1/2" subwoofer has an impressive 11.5 mm of Xmax. Subwoofer to be a mate to the Microbe design and the output levels are well matched.
Power of 60 watts the Cerberus can reach levels just over 100 dB with no excursion problems until you get below 25 Hz. The enclosure is an 11" vented cube tuned to 36 Hz with an f3 of 35 Hz. The project uses the Tang Band W6-1139SC 6.5 subwoofer along with theĭayton SA70 70 watt subwoofer plate amplifier.
So despite the small 6.5" driver this woofer has a lot of bark. Cerberus is a character from Greek mythology that is a three-headed monster hound who guards the entrance to the Greek underworld.
