Here's the conclusion from the last video where it shows the Thiele-small parameter data and dimensions of the Lightning Lab 2XL dual 2 Ohm 1000w RMS subwoofer. This time, we will design and build a box that is able to output its maximum on full tilt without compromising the resonance tuning and overall enclosure bandwidth range of sub frequencies. To achieve all that, we need to crunch the numbers on the drawing table, the Bass Box 6 Pro.
I put a little effort by showing the computation and design calculation on the software a little longer than the usual. You will see I inputted a box frequency of 40Hz in a preferred enclosure dimension and you might think that this is a little bit high for a 12" beefy subwoofer. It is because Bass Box Pro 6 actual system tuning is always less than -4 to -6Hz. You will also see the wonders of BB6P on its many features such us vent sizing, port air velocity, system impedance chart, cone displacement graph, power to output graph and many other cool things in designing and building car subwoofer boxes using the awesome software!
Once again you will see how we used the carpet seam notch technique. The technique used to hide and glue carpet seams seamlessly clean and sharp. And as the usual we used high quality high tensile machine Allen head bolts in securing the sub on the double MDF baffle. Pretty solid!
And as the usual, we use our trusty little Dayton Audio DATS v3 in verifying actual system impedance and tuning. Turns out, the subwoofer box is tuned at 34Hz full tilt.

We would like to acknowledge our fellow YouTuber "E Dud" https://www.youtube.com/channel/UCjRGRub7XTtPhjMWeMOM83g - for pointing out very similar subwoofer products to this Lightning Lab 2XL against different known expensive brands like the following:
So I think that is all for now and let us everyone know what you think about our latest episode today by commenting. Catch up in the next few days for I will upload the BASS test video! So be sure to subscribe and be excellent, be cool, be awesome
