Nice work guys. What is the advantage of doing the 4-6.5" subs?
Thanks!! When we run that much power to the interior speaker like our 3-way active setup, we need a sub-section that is not only musical, but that can keep up in volume to keep everything balanced. The benefit of the 4-6.5" subs is actually the type of enclosure that is vented.
This enclosure design allows us to "tune" the vent to the vehicle (Think adding a turbo to an engine) to better match the acoustics of the vehicle. In terms of displacement (moving air per stroke), it is equal to a single 10-inch, but one that can handle 1000-1500wrms of power while providing us the sound quality we need.
We have not found a 10-inch subwoofer that will fit under the seat, that can handle 1000wrms and give us the sound quality we desire. The best under the seat so far is the Focal K2 Power 10-inch in our vented enclosure but requires customers to cut the bottom of the seat to fit.
A traditional setup, several subs 10-inch sealed works well on lower wattage, basic stereo upgrades like a 2-way. But a sealed enclosure removes our ability to tune to the vehicle, so we only can do so much with a sealed enclosure. These trucks are very picky and even small changes in vent placement, subwoofer placement, etc can make a big difference.
In this video, we have 1200wrms going to the interior speakers and we need a subwoofer setup to match that same power. Running only a 600wrms subwoofer setup would not suffice, we would destroy the warm, smooth low-end extension by running the sealed subs into the ground.
That's why we run the 4-6.5, not to be different, but using more science and having the ability to tune the enclosure to the truck
