MTH-30 with Eminence Kappalite 3012LF?

Hi, Can I use the Eminence Kappalite 3012LF in the MTH-30?
And with RCF-LF12G301 ( www.rcf.it/it_IT/products/precision-tran...transducers/lf12g301 )?

Please answer me quickly...

Thanks, Giacomo.

I took the Hornresp input parameters for the MTH 30 from the construction thread. and run the sim for the Eminence Kappalite 3012LF.
There is good news and bad news...
The response has more ripple. smiley6
The power that it will take is increased smiley1

The Precision Devices 12sb30 driver hits Xmax (7mm) at about 45V (250W / 8 Ohm load)
The Eminence driver hits Xmax (9.1mm) at about 52V (340W /8 Ohm load
Attachment shows the Hornresp sim for the Eminence in black and the PD driver in grey.
How many cabs were you planning to build?
Note that either driver will require a High pass filter at about 40hz!

The RCF LF12g301 Driver sims up almost exactly like the PD 12SB30.
There is not a lot of difference in the response It may be a slightly smoother frequency response if the quoted LE of 2mH @ 1khz is more than the PD ( for which the LE figure is not given)
Xmax (6.8mm) is still reached at 250W

about Xmax: Hornresp sim excursion on a sine wave, but music is not a sine wave and never in music you will hear a sine wave at full level.

If you cut at 120Hz, you can easily take a margin of 3dB, so the Xmax will not reach the limit at 250 watts, but 500 watts in reality.

Ok thanks at all! I will use the RCF smiley2

what about the b&c 12tbx100?
i got 2 of them. can i use them in this cab?

I did a quick sim and the frequency response looks pretty ugly with the B&C driver - Probably not a good match for the MTH-30. smiley6

thx!

Could someone please be as kind to sim the eminence bp102 4ohm in the MTH?

Specs here www.usspeaker.com/legend%20bp102-1.htm

Thanks in advance

Sorry but it's not a very good driver for this cab as you can see from the sim...
It's not very linear smiley18 and is have too small power (sorry for my bad english).
Grey: PD12SB30
Black: BP102

You can use the Eminence Kappalite 3012LF but i think the best solution is the PD12SB30 or the RCF LF12G301...
