An update on my system. Have been trying out a 3 way configuration with a 2370a/2426h combo with xover at 1.2khz. Working well.

Got another titan built and a quest qa3000 to power them.
Here's a quick vid.

Otop12's are beta12 + melded array, titan 48 is ande 1560 15". Town is Mount Torrens and yea no noise complaints yet . When not being used for gigs the titan works well as a pc sub .

Just messing around with the t48, quality isn't great but you get the idea.

Using a dbx driverack for all the processing and an amp that does 25v per side one for the titan and the other otops in parallel. I will probably try limit at 25v for now to prevent the amp from clipping. I've been running it instead of my slim tht for a test and it sounds great for music in a small...

Got the cab up to usable status, still need to install castors then do the finishing work. Very impressed with the way it sounds so far and will definitely be building more. Sounds very smooth and powerful and seems to be fairly flat right down to 30hz. Still hits the lows well with the 24db 40hz hi...

Progress has been slow but I'm up to the point where I'm planning to attach the side today. I'll only be able to test it next week but at least that will give the PL a good chance to cure. Did some testing on my amp and it only outputs 25v (unloaded) before hitting the red so looks like I'll be need...

The otop's are sounding great so far, clean and super loud. Still playing with the eq though as they can sound a bit harsh but I am looking forward to hearing how they sound with the titan. I am powering with a scorpion amp that I don't know much about but its probably a couple hundred watts at best...

Building a 24" wide t48 with the Ande 15" driver, this thing is built like a tank and also weighs a ton

A few build pictures of OT12's

http://www.jdsound.com.au/products/446-ande-15-sb15-1-400w-8ohm-driver-speaker.aspx I guess this one should be even better then, 400w and 9mm xmax but even lower qts at 0.19 Edit* Never mind, think I just found the one :shock: http://www.jdsound.com.au/products/886-ande-lb1560-15-600w-8-ohm-driver-s...

Would this be a better choice? 3db higher sensitivity and 8mm xmax but qts slightly low at 0.21, less power handling and smaller diameter voice coil.

I managed to contact fs audio and they say xmax is 6mm, passable I guess but for $150 could build 2 t48 for cheaper than 1 3015lf. Just doing the finishing touches to my second ot12, pics soon.

Well not entirely sure but dial was about halfway on the amp. I don't know much about the amp because its old but I think its around 200w. http://www.ebay.com.au/itm/Audio-Assemblers-Scorpion-Series-4000-Mosfet-Power-Amplifier-Rack-Mount-/360756340778 Similar to this one but the 8000 series and was ...

Just an initial test of the first otop around 800m away in the vid.
Was surprisingly clear sound around most of the town
Now to build the second.
