12 tweeters from one amplifier, how did he do that?

dude thanks for putting up with my stupidity.. i think i figured it out in idiot terms. I think my best bang for the buck would be to get another single BL (dual 2) and wire that puppy parallel which would show a 1ohm to the amp. now just to be sure that i am learning if i were to do that setup would that sub see the 1800w each coil or 900 each coil (wired parallel)?

oh yeah the birth sheet says 1153 @ 4 ohm, 1739 @ 2 ohm, and 1890 @ 1 ohm

BTW the only reason im asking is because i want to push that thing to the limits (gained down a little of course). right now my current BL (10" dual 1 in series) is in 1.3 cubes with 15sq in port area and sounds pretty good.. but I want great. i want to get all out of it that i can and it seems like it is currently being underpowered with the series configuration. so i figured i could purchase 1 more dual 1 add those 2 together and wire it parallel for a total 1ohm and still get close to full output from my amp.. just looking at what my available options are..

I think the part I bolded in red was a typo?

Like helotaxi said, the subwoofer being wired in series won't have anything at all to do with it being underpowered. And the difference between the amplifier's 2ohm power output and 1ohm power output is completely negligible and inaudible.

Also as helotaxi pointed out, you'll actually get slightly better performance out of each subwoofer if you purchase a 2nd dual 1ohm BL and run 2 subwoofers. In theory, adding a 2nd driver without increasing power would yield a 3db gain (keeping the alignment the same as well).....but you are probably experiencing fairly signficiant power compression with 1800w on a single driver. Adding a second will decrease the power to each subwoofer which will decrease power compression, which is a good thing. It would be possible for you to actually increase peak output by more than 3db due to the decrease in power compression, which robs the driver of output for a given amount of power input.

that wasnt a typo I was just thinking if i got a different sub and ran it solo but @ 1ohm i would have a noticeable increase but since i wouldnt notice the difference thats out.. So are you saying that my current setup my sub is seeing 1800w, 900 each coil (well 869.5 each coil to be exact )?

Presumably, yes.

And were also saying you could set your gains with an O-scope to 700w instead of 869w and would NOT hear a difference. No way no how. Add to that you won't be running near clipping and it is a much better choice. There will be an output difference but it will only be measurable, no audible.

yeah I did the gains with an o scope (got a good deal on one on ebay ) and im not clipping now but I might give myself a little more headroom when I setup my front stage next week..
