Hai mr. marc and others I'm a dj from suriname(dutch is my langu). My english is not so good, but i will try to explain my question.

I bought 4 18lw2400 drivers..I already make 2 ms-46 cabs..I like the output but i have to push it hard to gain a max spl with good bass response, everything in the place is rattling, pants wappering. Is this a good cab for my drivers?what can you tell me about the cone control in these cab for my drivers.is it safe?

i'm looking for a cabinet with max spl for these drivers(the AES is 1200w). freq from 45 to 120hz. i'm playing in/outdoor at big hall as 25m by 40m..i want a punchy and chest pounding bass..and i think far throw is also a must..we must feel the bass.

I like the good work you guys do on the forum esspecially mr. marc. Very Happy

thnx

Hi !
The MS46 is not the best for great bass at 20 - 40m !
MTH46vs has a best sensibility than MS46 for example, with kick the MHB4818
Marc could give you information for the best cab for your 18lw2400 Wink

I've make simulation of the 18LW2400: it gives very good response. There's no problem with Xmax, just cut it at 35Hz 24dB/oct Butt, don't overload amp and it will be perfect.

Other cabinet like MHB-4818 gives more output and is very physical, but at the expense of size. So if you like the MS-46 and don't want bigger, keep the MS-46.

Oke, i will start making 2 more ms 46. can is the backpanel design of the mhb4818 the same as the old keele/jbl model or is yours different. can you please send me the design of the backpanel if it is different, i will make that also after the holidays or maybe next week for my p audio 600w drivers..

another question..my 2 ch amp gives me 1200W @ 8 ohm per ch, 1900W @4ohm per ch, and bridged 4000W @ 4ohm..how can i connect those drivers..do i have to use second amp?
for example 1 per ch or 2 per ch @ 4ohm or bridged 2 cabs?

The MHB-4818 is different from the old 4818, it is more sensitive by 1 dH more and has lower cuttoff, also more easy to build.

another question..my 2 ch amp gives me 1200W @ 8 ohm per ch, 1900W @4ohm per ch, and bridged 4000W @ 4ohm..how can i connect those drivers..do i have to use second amp?

Ideal power for your driver is 1500 watts per driver, limiter set to half of this power.

There isn't enough Xmax, so it could be a problem at high levels.

You can use this one:

You can put the P.audio in the MS-46 or MTH-46vs, but limiter power set to 250 watts RMS with a 500 watts RMS amp.
