I have a JL 300/4 with a similar setup as yours (front components and a sub). I've played with it quite a bit but I keep coming back to setting the high pass and low pass filters at around 80hz. I find I prefer the 12db slope instead of the 24db slope but that's a matter of preference.

Thanks again Percy! Cool. I didn't do any of the setup. I'm sure the installer did it. It's science again. haha. I kinda worked w/ the installer to setup the amp, but I wasn't 100% clear on everything he was explaining to me so it probably could be tweeked even more. I'm learning as I go. Here's how I'm set up now:
(EDIT: Settings as of 8/05/08)
Amp...Rear Channel (to sub):
- Filter Mode = LP
- Filter Slope =
12 db
- Filter Freq. = ~
90 Hz
- Input Voltage = Low
Amp...Front Channel (to fronts):
- Filter Mode = HP
- Filter Slope =
12 db
- Filter Freq. = ~
90 Hz
- Input Voltage = Low
Amp...General Setup:
- Input Mode = 4 channel
- Remote Level Control = rear channel
- Pre-outs From = F+R
Kenwood HU:
- Sub-W-Level = +
1 db
- Bass Level = +2 db (Freq. =
100; Q Factor =
1.25)
- Middle Level = +2 db (Freq. = 1.0 kHz; Q Factore = 1.00)
- Treble Level = +
2 db (Freq. = 15.0 kHz)
- HighPassFilter Front = Through
- HighPassFilter Rear =
100 Hz
- LowPassFilterSW = Through
- Loudness =
On
- HU Amp =
On
I'm gonna try and fiddle w/ the settings like you mentioned & see how things sound and change.

Once you get used to it you'll find you hear elements in the music you never knew were there. You'll hear it like the artist intended, which is what high quality sound is all about.

Yeah, I'm definately not an experience audiophile and am learning a little bit @ a time. I was kinda partial to using the "Loudness"...but was advised I should set things up w/o 'Loudness' turned on. Gonna keep reading up & fusing w/ stuff.

It doesn't thump like a bigger driver but does a great job and blends in really well. And it's the perfect size, in my view. Plus, it's more than happy with 150 rms watts. |
Wow! That looks great! Shoots, if they had that @ the local shop it would been great. On the wish list it goes.

As for the box, I'm surprised that such a small box works for that sub. Any idea on the volume you ended up with? It looks tiny, and I'd love to be able to minimize lost space in the trunk.

Thanks syzygy. It's a 10" woofer. To my un-trained ear it sounds good. The local shop said the higher version JL subs sound/were much better than the one I got. The woofer percy mentioned probably sounds way better, is around the same size, and doesn't cost too much more...seen it here [
CP108LGW3V3*::*Loaded*Enclosures*::*Car...] for $239. If that sub was @ the shop I'd have got that one. Shucks.
