I don't know if you are doing box designing at the moment but I may need something drawn up, if you are.I disagree with box rise and that whole concept of how that works. The resistance is fluid. You have no idea what your rise is playing music. The resistance is changing 100's of times per second, depending on the location of the coil relative to the flux field of the magnet. Switching between notes is going to rise differently than a tone. For daily, there is almost zero benefit to designing around rise.
So it'd be better for him to get 2 D2 coils wired at 2 ohms to be easier on his electrical system?Nominal resistinace in ohms seems to be simply the wire resisitance. you can actually have a really low resistance potetionally when a sub is at peak xmax in one direction and the suspension pulls it back down. And in all reality, higher average resistance loads on the amp will make the amp more efficient and run cooler, which can often times makes the system play better. I've hooked up a fi q 15 at 1 ohm vs 4 ohm in my f150. only had it all stock electrical + a batcap 2000 in the back. The sub was literally almost as loud at 4 ohms as it was at one. That's 1200w vs 450w on my amp. There's a balance in electrical systems that's important to find. I had 380 ah worth of batteries in my exploder and a 300 amp EA alt charging @ 15v. All this for a 200 w x 2 channel and 2 1200w sub amps bridged. I was able to run my subs at 1.4 strapped vs the rated 2 ohms. When you start doing that, running low ohms without a very hefty charging system and batteries, you can get wild peaks because the sub resistance at certain notes will be way louder because you're already struggling to keep voltage and when that notes hits and the resistance drops at that note, it puts more power through the sub. But when your box is musical oriented with a smaller port and it's designed for a wide bandwidth, that more even resistance keeps the sub voltages more in line across your frequency bandwidth. My 2 18's had an insane peak around like 65 hz where I would drop into the 11 volt range at full tilt, even with all of that electrical. it was loud as ****. Had to do with my low tuning and the fact the box was sort of larger than it needed to be for extending up that high. So on my 9887, I did a like light -6 or -12 db per octave crossover at 50 hz, so it would soften everything above 50 hz a little, and wouldn't rape my equipment playing over 60 hz. Worked out really well actually.
I'm starting back.I don't know if you are doing box designing at the moment but I may need something drawn up, if you are.
I wouldn't do that if you can run at 1 ohm and it gives you more power. Literally every factor plays into what I was talking about. Clean signals, good voltage, quality of sub and box, vehicle resonances. I was just saying if you're building a daily system, it's way easier to do close to the vanilla ratings when pairing amps and subs. And just do a musical box based around bandwidth you want in either direction. I don't see much gain for doing stuff SPL competitors do like running lower than rated ohm levels on your amp or designing a box around it's electrical resistances. You just give the sub what it wants, good clean power and a good box, and it's going to be loud regardless. Box rise is there but chasing it for music it's like chasing the dragon. It's just going to move around too much because you're playing more than 1 tone.So it'd be better for him to get 2 D2 coils wired at 2 ohms to be easier on his electrical system?
Now I'm pretty stupid and I'm sure this has come up a million times. The system will be just Daily/Showing off so what is the size I should go for? I'm really just wanting something bigger than 12 since it's not a common size in my neck of the woods. Also the upgrade options on the SSA page. Is there anything I should go for or not?I still vote for 2 Gcon 15s in that 06 Tahoe, That smart3 should be just enough to flex a pair of these nice.
Nice and simple too, ported subs up/port back
Flatwound coils have better heat dissipation because they have more surface area. Most of that stuff seems more competition oriented. If you're running higher power on these, you may opt for the cooling options. Idk if I would do the extra spider because of it's affect on music. I'm not sure what the lead wire upgrade actually changes.Any input on the options for the GCON sub?
