PS, passive is technically possible but a really bad idea - the inductors required would be big, heavy, expensive and even then probably still eat up too much power & degrade damping factor too much to be worth it.

gahh.. really dont want to add another battery, what would happen without the hpf?

Why do you need another battery?

that would indeed work! and I guess it shouldn't be too hard to figure out how to set a HPF at 50Hz

Why 50Hz Hi Pass? That seems high even for a Tham 12. I would expect 40hz, or maybe a bit lower dependent on Driver & power level.

Thats what mr tham is recommending if I’m not wrong, 

But what happens if no filter is added?

I’m also trying to learn hornresp so I can simulate different drivers but I never get the same results as the simulations in the thread, is there a guide someone can recommend as a starting point? I really want to learn.

i was messing around with simulation some drivers, is this the correct way to do it? 

Its the Precision Devices PD.121/2 8 Ohm

You haven't modelled a tapped horn though, so of course you're going to get different results.

Double click on the field you have marked Nd and change that to TH.

As a sanity check, if you're still learning hornresp, start with the same driver that Anders modelled too, just so you can be sure you've got all parts of the model correct, before trying other drivers.

that solved the problem and i now get the same simulations as Anders, thank you! Finally i can start messing around with different simulations on the tham10 and tham12

Found this For-X XMB-12N which seems to look great on the simulation and only weighs 3,65kg so it would be great for portability. 1 x Pi. guess its the 4 ohm that makes it more effeicent/louder

Yep... I’ve been running mine (I have 4) hi passed at 40Hz with a 48db slope for the last 8 years now without any issues. I'm using the Beyma 12LX60V2 drivers and powered by either a QSC PLX3602 or a Peavey GPs3400. I reckon I could easily give them 50% more power than I currently do, but as yet I’ve had no need to push them that hard!!

I'm going to build a sub to get more oumph togheter with my soundboks 3, would you rather go with tham 10 or 12? Some people have said that the tham 10 doesnt have enough low end, does anyone have input on this? Or should i go a completely different route. Would like it to be as portable as possible ofc max weight of about 15kg
