JL 13w3v3 & JL 500/1v2

[GregU 10+ year member]

I just bought a JL 13w3v3 and will be making a sealed enclosure for it. I'll be using a JL 500/1v2amp. My questions is, JL reccomends a 1.75Ft3 for sealed enclosure's, would building one to 1.9Ft3 give me better results for lower Hz response? I'm going for SQL and low bass is very important for me. Any opinions? This is also going into a Scion TC hatchback, if it matters.

EDIT: dealercostcaraudio had a black friday special on the JL 500/1v2 for $339 and the 13w3v3 for $179 brand new. I couldn't pass that up.//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

1.75 + 13w3v3 volume //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

just go ported if you want more bass.

Have you gotten the amp yet. If not I recommend the arc audio ks 500.1.

I'm not after SPL, going for SQ on this setup. Would the 1.75 give me good low frequency response? Or do I need to go a little larger? The F3 on a 1.75 sealed is 37.7Hz. And the sub displacement has been subtracted for the given volumes.

You can do SQ w/ ported, just tune lower //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Yeah, I already bought the amp.

low tuning = more SQ //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Gotcha. I've been doing so more research on this topic and I'm finding that the difference in a 1.75 and a 2.0Ft3 will make little difference in sealed boxes, but will yield a lower LFE, slightly. The 1.75 has a qtc of .96 though. I would need a 4.5Ft3 to get a qtc of .72. Am I on the right track here? I read that article where .707qtc would give me the best SQ? But that seems a little extreame.

I would go with the manufacturer reccomended enclosure size and tuning for that sub.
