MTH-30

How high does this cab go to with the PD driver. It says from 42Hz. would it make a good kick cab?

Hello

Plan said nothing about bracing.

What panels should be braced ?

if you look at the first photo after the plan, you can see what and where to add bracing...... hope this helps.

Ok, i see that, but what about unbraced side near horn mouth?

Anyone know how low 1/2 will go in 1pi? also how high is everyone crossing these?

Cheers

The pic of the MTH-30 on the plans page is my smiley16 !

good job Geko...... smiley16 How have you found this cab so far......

It's a very good cab... Mine is loaded with RCF LF12G301. It goes surprising low smiley1 ! It's a SUB and i need a kick bin because my tops are only 2 8" smiley24 ...

Best Regards, Giacomo.

Greetings all!

I think I've found a suitable driver, made here in the US (and a bit cheaper then the PD)

Can someone more well-versed in HornRESP model this? I happen to have a couple of these drivers that need to be reconed sitting here, if it sims well; I'll build a bunch!

If someone is thinking about modeling the 4012, would they mind modelling the Delta 12 lf as well? I have 2 on hand, and although I love them in my T30s, I just built some T48s, and I want a nice small box to throw the d12lfs in.
