Hey guys! I just downsized from an AQ hdc318 in 6+^ft box tuned at 40hz. Now that I have these JL's I am having a really tough time deciding what to tune these subs at and how much room to give them.
Let me first tell you about what I would like to accomplish from this enclosure. I am told that these JL's hit very low with great sound quality. That is exactly what I want. I want these to have the perfect amount of bass while retaining as much sound quality as possible. I listen to 99% edm (dubstep, drum & bass, house, techno, ect.) and want the tight, clean, punchy bass while also getting low and loud. For now, these subs will be in a saturn vue but will more that likely be put in the whatever vehicle I buy new in a few years (at that point I will get a box to perfectly fit my cabin's geometry, along with all the rest of the sq stuff I need).
I have been reading that these subs will do best in a ported box. Many people commented saying tuning around 25hz produced good results, but did not specify what there goal was. First question: what would be the best freq to tune my subs based on my goal?
Also, I would like to keep this around L:28 x W:24 x H:26. I tried using google to find a converter to find cubic feet. Each converter is telling me when I type in the dimensions to find the volumetric dimension of a rectangular room that the result is 17472^in.
When I use an online ^in to ^ft converter I get 10.111111^ft and I know that's obviously not right. My second question is: Is it always the case that the more cubic feet (as long as tuned to the right freq.) we have the louder we can get? (assuming we don't go too big. Like a range from .5-15). Basically, is there any reason these JL's would sound better in 4^ft @25hz opposed to a 6^ft @25hz? Third question is: How many cubic feet do I have to work with, and exactly how many cubic feet should I use to get the best results based on my goal?
oh, and I forgot. Is there any advantage to having the subs/port facing upwards vs towards the rear, ect?
