Finished the sub install and salvaged the old box for now.

New speaker gasket tape

Replaced the 16 gauge wire with some left over 10 gauge power wire. The wire connectors on the GB12 will crush or cut any bare wire. The solution is to tin the wires with a good amount of solder. Colored shrink wrap helps identify positive vs negative quickly.

I needed the wire to be long enough so that I could comfortably install the subwoofer but didn't want the wire to rattle against the box so I wrapped it in some leftover foam from a fast ring kit I had laying around.

Repainted and ready to go for a listen

Now to break it in and do some listening. Going to have to change that signature below too.

Found a couple hours to start on the new sealed box. The front will have another 3/4 layer glued to whats already there and it will look pretty much just like the ported version above, only sealed this time. Volume is estimated to be 1.275 cu ft sealed after driver displacement.

I haven't had enough time to put much into tuning other than the basics but I have noticed that I like the sparkle of my GB10 in my truck more than I like the GB15 in my CX5. I know this is because of the location of the GB15 being off axis in the CX5. The GB10 in my truck (other build) are more on axis which are located in the A pillar. Right now my truck has the best sounding system overall. I'm going to start playing with the GB15 on axis in different locations so I can plan some custom work for those.

Attached here is the BassBox Pro estimate for response with plus 3 db @ 50 Hz and a 12 db per octave rise estimate for cabin gain. Red is this box sealed, orange is in a 1.029 cu ft sealed box and Yellow is that ported box you see above with 33 hz tune.

Getting GB15 ready to go in with 22uf capacitors. I have plans to install these in the A pillars later but want to have sound now. :laugh:

What made you decide to use the 22uf caps?

Nice build man! I run the gb60 and gb15 in my s2000 and really like them. i have yet to hear some gb10 though. I am toying with the idea of doing the 3 way in my 4runner but i'd have to do the gb60 in some kick panels i believe, don't think there is any way to fit them in the doors. They barely made it in the s2000.

I would like to hear how you like the gb15 compared to some other tweeters that you have used in 2 way systems.

Garage time is certainly a rare commodity, but you have certainly made the most out of your opportunities. I think it was beneficial to place the three sets of speakers in the positions vacated by the previous drivers to get a comparison, then try them in locations / box that may suit them / you better. More work, but it settles down the, “I wonder if.......” question a bit. Good job!

I actually used 47 uf I think if I remember right now, which was roughly 2 octaves below the x-over point.

I haven't had enough time to do a thorough tuning with these but as they are now in the dash locations (not ideal) they are easily the best I've had, especially when playing at high volume. The only tweeter that comes a very close second is the SB Acoustics SB29RDCN-C000-4 Neo Magnet, Ring Dome Tweeters. Those are impressive for their price. I have the GB10 in my truck that are located more on axis in the A pillars and paired with some JL C5 mids and those are very impressive sounding tweeters and I'm extremely happy with them. I plan to mount those GB15 in the A pillars of my CX5 too, hoping they give off the same sparkle as the GB10 do now in my truck.

The GB series of speakers are basically what everyone on this forum has said they would be. They are that good!

If you are disappointing in them than I'm going to say you likely did something wrong or you have very high standards beyond my comprehension.

What drivers did you get?

Update, now that my sons baseball is done I have a little more time to mess around with the car. I’ve been slowly chipping away at this sealed sub box that is just over 1 cube with an angled back to match the seat back in my CX5. If I like how is sounds I’ll finish it off with carpet. It’s got a dual 3/4” front baffle and has generous internal bracing. It’s a pretty stout box. In the first picture is my Ford F-150 and Van. The F-150 build is located here.

I’m starting to think three way active again with this car but for now the two way does sound awesome. I need to think of an idea on how to secure this box so that it doesn’t become a projectile in the event of a collision but I’m not sure how yet. Open to suggestions on that?

If its going against the back of the seat, you can secure a cleat mounting system to the back of the seat and enclosure so that its lip of the one on the seat is facing down and you have to fold the seat down to slide the two parts into each other, then just fold the seat back with the box still attached. This will lock it into place while still being quickly and easily removable. You will just need to use something to keep them decoupled or super tight to prevent rattles against the two pieces

Nice, we have similar product like that sometimes at work. I like this idea!

EDIT: I think some of your CCF might work for decoupling or preventing rattles?

Its raining out today which is a good thing for me so that means there is nothing to do but mess with the car audio system in the garage :D and the wife cant do this :snobby: when there are chores to do outside. She did just tell me that I was playing it too loud and our house sounds ghetto. :laugh:

So I put a quick coat of black paint on the box but didn't put any effort into the finishing of the box because its a test box for now and I said to myself, if I like it than I'll just carpet it. I also added 1 pound of acoustic fill from Parts Express and mounted the GB12 D2 in the box.

I'm also contemplating making some kind of pod or enclosure for the GB15 so that they are pointed on axis from within the factory location. I have extra factory grills so if I screw them up I wont be too upset about it. In the picture below I propped them up on their sides and pointed at me to see if there was a difference and I can hear slightly better sparkle when they are in this position.

GB12 Sealed 3.jpg

Here is the GB12 sealed measured response before EQ and then after EQ.
GB12 WO EQ (purple) and with EQ (green).jpg

Here is the GB15 reponse in the dash pointed up at the windshield and then on axis pointed at me as seen in those pictures.
GB15 on axis (red) vs off axis (green).jpg

Here is the full response with the GB15 on axis. If I keep them like this I will fix that hump around 6k with the DSP and time alignment at the X-over point. I also lowered the HP from 2k to 1.8k and they sound good.
GB12 sealed full response GB15 on axis.jpg

These graphs are showing up on the forum like they are truncated so they look worse than they actually are. Somehow I didn't get a response curve of the ported box before I put the GB12 in the sealed box because I thought I had a saved file somewhere but I guess I didn't. It sounds surprisingly good and the drop in SPL, although noticeable, isn't as drastic as I was expecting it to be. I'll leave it this way for a while to get used to the new sound and see if I like it or not. One thing I've noticed is the bass sounds even more up front than it did before and it was good before.

So I'm looking for some ideas on those GB15 tweeters. Should I graft them into the front grills so they are pointed on axis? If I use grill cloth and fiberglass to graft them in than where do I get some vinyl or something similar that will match the interior? I have never done this before so I have to ask the noob question.

Somewhat off topic but I see a three way coming in the future for the F150 build. Those GB10 and JL C5 need a little midrange help. ;) The GB15/GB60 combo do a better job in that department. If these subwoofers werent so expensive I'd get another one and have a dual sealed setup. Listening to Mullings dual sealed JL W6 in his Prius a few months back makes me want to try it. That was an awesome sounding system!

All After EQ except the first graph in purple is the sealed box before EQ and the green is after EQ on the sub only.

The dip at 400 is a null I get no matter what midbass driver I use so I just match left to right so the stage doesn’t pull to one side in the frequency range. I think there is some cancellation in the crossover of 1.8k where it dips and I think and the tweeter needs a little work too, which I plan to tackle after I figure out the tweeter locations. I’m all ears though for any knowledge I can get from a guy whom I know tunes a lot of cars.

I’ve been playing more music with the sealed box and I’m already missing the impact of the ported box a little. I also verified that the tuning of that ported box is actually 30 Hz, not 33 Hz like I was aiming for. Gotta give it some time and see what happens!

EDIT: here is what it is now against my target curve.
