Hi yesterday me and my mate were test running his new turbo sound rig and it didn’t take long for the neighbour to come round to tell us that it’s definetly working haha as it turns out hes an ex copper Stern Smile but still was actually sound enough that he gave us a lab horn that he had in his barn for years if we agreed to turn the rig off banging result. Me being me I’m now curious if it’s possible to upscale the plan and make it 15/18 or even 21” having already done loads of research on them I understand that they can get through drivers quickly if not used right and are very specific with the eminence lab 12 drivers so makes me think that the likelihood of it being successful is very slim but the idea interests me enough to atleast ask what people think if I had to modify the compression ratio and stuff like that then that could be possible hopefully what you guys think? And yess I know it’ll be absolutely mahoosive but I don’t care how big and heavy it is even if it does take a forklift or loads of people to move one

The polite answer is no.

Realistically, if you think the lab horn design would benefit from modification, demonstrates that you do not understand it.

Designs do not, as a rule, scale up and down. It just doesn't work like that. There is not a bigger driver that is exactly the same as the lab12 driver but just bigger. So just making the horn bigger doesn't just result in the same results but 'bigger'. Unfortunately there is a lot more to speaker design than this.

I get the impression you are looking for the biggest ,badest, horn out there (understandable, we've probably all been there) but you need to understand  that the biggest and baddest, does not necessarily use the biggest driver.

I recommend you commission some terrahorns or some of rog morales 2 part scoops (both fairly awesome no compromise designs) and if they don't do it for you, do a lot more reading and learning.
Keep pushing on, things are gonna get better.

I'm certainly no expert on this kind of subject but I think the answer the original poster is looking for is fairly simple.
Several Lab horns coupled together to make one big Lab horn.
In all fairness I believe Eminence now make a Lab 15 driver so a larger version could probably be designed. Just scaling up is not the way to go though, it would have to be designed from scratch.
Or as pointed out above you need one of these:
A big Horn
Cheers, Chris.

I don't think I have ever seen someone say 'I want a labhorn but bigger', what are you trying to do? Raves for elephants? 

4 Labhorns have no problem playing down to 30hz and human music doesn't really go below 35hz... 

Maybe I really should design my 21 inch 'Compensator'

This is true of all gear. Run the tits off it and you will be killing drivers.  

Bring enough rig for the gig and limit conservatively and they will be fine. 

Rather than redesign a working design you could build another one or three!
