Subwoofer Build with Concrete Base - by SoundBlab

This Subwoofer build with Concrete Base uses the concept of a Linkwitz Transform (LT). It essentially boosts the bass output of a subwoofer driver in a smaller sealed enclosure compared to the typical larger enclosure required by a ported enclosure. I am using a miniDSP 2x4 to implement the LT. The subwoofer uses a 300 Watt amplifier that I have built a few years ago. The driver is a JBL GT4-12 inch subwoofer and the enclosure is roughly 35 litres sealed. Buy the miniDSP 2x4 here on Amazon.com: ► http://amzn.to/2aWkeXG You can read more on the LT here: https://www.minidsp.com/applications/advanced-tools/linkwitz-transform or here: http://www.linkwitzlab.com/ Please be sure to subscribe to this channel and don't miss out! ►► Subscribe to my channel ►► https://goo.gl/EWMSXV Follow me on Instagram: https://www.instagram.com/soundblab/ Follow me on Twitter: https://twitter.com/soundblabs/ Follow me on Pinterest: https://za.pinterest.com/soundblab/ Recommended Tools: - Makita 18V Cordless Drill & Impact Driver: http://amzn.to/2b56Oev - Makita Finishing Sander: http://amzn.to/2b57nVG - Makita Random Orbit Sander: http://amzn.to/2aC8GXa - Makita Beltsander: http://amzn.to/2aHi63k - Makita Circular Saw: http://amzn.to/2bbhKGP - Makita Jigsaw: http://amzn.to/2bbiM5H Music: Kai Engel - Comatose
