Thanks that was quick ( the B&C website says 13.5 xmax and PE says 12.5mm)! If for beer reasons I were to exceed 69 volts and xmax, I should have sufficient xmechanical (in this particular driver) that the momentum of the cone slowed by the stiffness of the suspension shouldnt cause damage correct ( I will bring my calipers haha). As Xmax is exceeded I will no longer have linear voltage/voicecoil movement and distortion will increase. Just curious of what happens when a driver in this case is pushed harder than it should be. I have those friends who are always cranking stuff up. I came out of the shower on the third story of our airbnb house to the smell of electrical fire and found my friend in the bassment with my cubo 10 mod trying to turn it into a fog machine(flavoring the voice coil). Running most of a behringer 3000 into an alpine type r 10 haha. People these days.

With a 38 Hz 24dB BW HPF, the 15SW115-4 will no doubt burn before it breaks.

If you have the iNuke DSP you can use the dynamic EQ at the excursion peak instead of voltage/power limiting to help keep from flogging the suspension too much.

I've smoked a 3" coil with ~120 watts (sine) seemed like less than a minute
a 25 watt soldering pencil gets kinda hot

I nuked a tweeter twice with a "150WPC" amp, it turns out the amp makes 150V p-p.

I want to build the Tham15 with another dimension on the outside 70x50x55cm from 15mm Plywood - could some one simulate me this with these speakers

18sound 15lw1400
18sound 15nlw960
B&C 15nw100
Faital 15xl

or what ever you like

the goal will be as deep and loud as possible

Amp is a Labklone 10000 oder 14000 wich is 2500 to 3500 watts into 4 ohm.
also the speaker is the 4 ohm version

i want to use only one sub per channel and as horntop is use a community SLS 920 so this will be a really compact PA
the SLS will be driven in 2way active mode on 10000 labklone

if i have to or more subs i will use more amp channels or go with the hoellstern 12.2 oder 20.4 Hoellstern Audio Amplifiers

hofman's iron law says,pick 2 of low,loud,smal.
your cab is small so it won't go deep,or it won't go loud.
with 120 ltrs i won't bother making a th.
i would choose a normal br with an 18"
