Lowest inductance 18's?

What are some of the 18" drivers with the lowest Le? Does it even matter?

Nice looking subs... I like the baskey/spider/motor look, the accordion surround not so much. 29Hz Fs isn't tooo bad but 24Hz or lower preffered. That 20mm Xmech makes it a no go for sure, 14mm Xmax doesn't help any either.


Oh and they have to be 18's.


Thanks to zora, he has gotten me to step out of my box with these 1803s. I am looking to go the opposite direction from the IB3s... monster beast subs! But I'd like to try some very low inductance very low Fs very high BL prefferably high Xmax but not a must... must have at least 40mm Xmech though.

Looks like the LMS ULTRA 5400 is just what I'd like, but at $900 a pop or as low as $650/per used, I just can't do that. So I am trying to look for some alternatives.

at least solid 55Hz-80Hz... thats the minimum... the ability to run up to 200Hz without issue would be very nice. I like a very exaggerated U shaped FR curve, I want my 20Hz-35Hz to be extreme, a dip from 35Hz-55Hz, then extreme high bass as well. Despite having four XBL^2 7" midbasses in very tiny tight sealed enclosures with 1700 RMS on tap crossed 80Hz-710Hz 30dB/oct.... it's just not the same as some subs Ive had running as high as 150Hz in the past.

Right now these 1803s are great, they take a lot more power than the IB3s and are so much louder. They have an overall fuller sound though to me it sounds labored...forced...like they are "just a slammin" but having to bust their butts to do so.

More specifically, they are a bit too loud from 35Hz-55Hz... they are sometimes a little painful. That is my least desired range. I am very lacking in the 35Hz down department as well as 55hz up. When songs come on with strong high content (above 55Hz-ish) and I listen at high volumes they start to stink yet they arent loud at all compared to music below that range.

I have a feeling if some 5400s were dropped in there, no EQ, I would be in Utopia, Nirvana, blissful heaven. I had to EQ the IB3s but I do not want to EQ these, or anything anymore. Today I very well may break down and center at 45Hz and end up at -9dB which could be bad. Over excursion on the lows I love so much, and cooking coils on the highs I desire.

Ah, more fun, it never stops with you guys... and I like it!


where you been? I been saying mad highs and mad lows for a U shape all along man!

Apparently I was lying my ass off! When I first dropped these new bad boys in I brought the EQ back to 0 but left the crossover at 200Hz. Right away it was a problem, so I dropped them to 80Hz and that alowd me to raise the sub level and get LOOOOUUUD.

Well I think they were still breaking in, I couldn't go too long free air in the house because everything was falling and spilling... the TV was hanging by the power cord and boxes of pictures were spilling, it was just a real loud mess that could have started causing damage.

Well today I brought the crossover back up to 200 and I am in HEAVEN! The problem? Current gets DUMPED into these monsters! Now that i am broken in, still my voltage drops... it's like watching the SPL meter...when the subs hit, it goes from 14.8 down to 12V instantly and back up and down with the beat. In these videos this is me taking it easy, only drops from say 14.3 to 13ish?

These subs ROCK, thanks again zora! I just need to get the money together to get the bracket adaptors and belt. These things can get insanely loud when I crank it for a few seconds and watch my voltage drop well below 12V but I know I am just asking for trouble. I'll leave them at 200 where I like them but try my bestest to take it easy until the other alt is added.

Well generallt 30Hz on up is pretty easy to get liud no matter what subs/alignment, and I have so much trouble stressing the hard part... that people are to busy trying to "help" me compramise so I can get "better" up a little higher. Had to fibb/exaggerate even to the point of changing graphs to only include the problem area and say that is was the only area that mattered at all, because no matter what above it was easy to acheive.

Was going to have a laptop rack mounted, no wifi now

earlier today I think I managed enough voltage drop to clip the amps hard enough to sound like metal.

finally gave in for a while and PEQed for a bit till I got tired of being nervous and put it back. 22Hz Q of 5 I think, +9dB maxed out

For so much airspace and being tuned so low, the bottom notes sure seem to fall off on me. Sure if I was tuned higher, 27Hz-32Hz, it would be MUCH more gain down low, but still... my low notes should be multitudes louder than mid/high, not multitudes quieter even with maxed out EQ.

I suck at this game.

IDK, I get that if I tuned to 30Hz instead of around 23Hz Id get a lot more output, but still, songs that sweep should still get louder as it gets lower even tuned this low, not quieter. With the IB3s, when i got a 148 @ 25Hz, I am pretty sure they would have gotten mid 150s above 40Hz. Same with these suckers. I tried retuning to 27Hz and that KILLED it.
