Hey guys. Sorry guys Ive been busy working today so haven’t had time to research this but looking for advice. I see Andy is selling his Gs12 subs for $169 right now and am trying to figure out if it’d be a worthwhile upgrade for me. I’m currently installing my build in a 2015 Camry with one JL 10” w6v2d4 in the factory wedgebox. which I’ve been powering with an Alpine 650 watt @ 2ohm mono amp. I’ve been happy with my solo 10” sub for awhile but am curious if this would be a nice upgrade for cheap. I’m going to build a new sealed box for either, and I’m running a 3 way front stage with a JL Twk88 controlling everything. Thanks

To my knowledge, W6's are more like GB's. W3's are more like GS's. If you have a W6, a GS would be a downgrade. Significant.

The w6 is hard to beat. That is even the sub ErinH just went with in his new build IIRC. I would keep it and spend the money else where.

I agree the w6 is no slouch. Main thing I was curious about was stepping up to a 12” over a 10”

Let’s do math. :)

JL 10W6 Sd - 50 in^2
AF GB12 Sd - ~80 in^2 (+1.8 dB)
2 JL 10W6 Sd - 100 in^2 (+3 dB)

If you double your cone area, you gain +3 dB. The 12” will get you to almost 1.8 dB using the W6 as a baseline and this would be true if we were talking about the GB12. The GS12 isn’t quite as strong as the W6 so it would probably be closer to 1.5 dB or a little lower. So it would make a little difference but not huge.

EDIT: Meant to mention that doubling cone area is a general rule that adds +3 dB when the cones are colocated (next to each other). If you double the amplifier power you get another +3 dB. So if you double the cone area and amplifier power, you get a 6 dB increase. Since the decibel scale is logarithmic, 10 dB is perceived as twice as loud.

I am actually in the same exact boat as I planned on my 10w6v2 but went ahead and purchased the AF GS12 since it was cheap. I am thinking about using the AF as I miss having a 12.

Thanks for the info! I decided to wait and run the W6 for now. I’m just starting my install which should take some time seeing it’ll be my first attempt making custom pods. It’d probably give me time to save up for a GB or something too

Awesome. Let me know how you like it when you get it going
