KFC-XW1300DVC - 12 Volt Tuning
Muscle To Spare 13-in Subwoofer
To finish off my listening test I put in the Bass Mekanik's V5.0 album, track six, "Dubalicious." This track has a very strong bass line and wonderful note shifts between 60Hz and about 30Hz. Here the KFC-XW1300DVC shines like no other sub. The 30Hz notes are every bit as loud as the 60Hz notes. Low frequency linearity and extension are the stand out features of this beast. Just to verify this, I measured the Kenwood all the way down to 20Hz and it kept getting louder and louder the lower the frequency.
Conclusion
When I first started this test, I originally ran the sub with 1000 watts. I was not impressed. While the KFC-XW1300DVC sounded nice, it did not have enough output to get out of its own way. As Kenwood recommends two of their X810Ds (2 x 800 watts) to power this monster, I decided to up the ante and added a second 1000 watt amp to reach the magical 2000 watts mark. The performance was transformed into a subwoofer that I would have no trouble recommending to just about anybody that was interested in a great, all around subwoofer - that is, if you have the budget to power it correctly.
