Proline is unforgiving, so are X1.

 = you have to be careful of signal chain! 


Was damage mechanical or thermal?

what processing to they run? high pass? limiters?

I think the use a reggae style pre-amp, but don't know from which manufacturer for sound control and so on. Probably not such a precise tool for pushing x1's to the limit..

The room on the picture is just our storage place and we didn't blew our drivers yet, it was another soundsystem from friends

There are es18 kicks on top of the x1's as you can see in the picture as well as in the description of the stack.

If you had 8x decent 1850 full scoops, powered by 2x Inf8Mk2, that would make a mess of that place, I'm sure.

You all ready mentioned that once in the thread...

I see, as said, I think they use a reggae style preamp. We play with a mixing console, x-overs and some studio gear, so we hopefully can control the signal chain a bit better...

I don't know if the damage was mechanical or thermal but my bet is they just run the amp too long and to hard + pushed frequencies like 60-80hz via preamp to get a breath-taking bass (= thermal?)

Cool.. Didn't rescan thread before posting.

Proline 3000s are beasts in 4 ohm bridge, not quite enough for 4 ohm stereo sub, but must not be clipped ever, as clipping circuitry is proven to be pants.

Therefore Inf8MK2 will drive 4x drivers nicely, for lot less weight.

If they ran without protection after the pre-amp (HPF / limiters), then I guess they were playing a dangerous game with an unknown setup!

Would be interesting to see a picture of the VC when (if) they recone the drivers.

I'm currently thinking about inf8, macrotech5000, ca18 or so on, but they are **** expensive.

We all ready had a few sessions where we powered our x1's with the inf8 and I was heavy, but i also hear a lot of negative feedback on how the void amps are manufactured.

Due to great supply on the second hand market in germany I'm thinking about:

2x Crest ca12 (2x1200 - 4ohm / 2200 - 4 ohm bridget)
2x Crest 8001 (2x1200 - 4 ohm / 2800 - 4 ohm bridget)
1x Crown Macrotech 5000 vz (2x2600 - 4 ohm parallel mono) (no THAT many on the market)

what do you guys think? 

Edit: there may also be some ca18 to find...

CA12 is stripped down version of 8001, so would forget about those for 4 ohm bridge.
5000VZ is nice amp, but old, and no where near the power of 8MK2.

You guys are dealing with serious bass notes, all night, so for you suggest either Proline 3000 in bridge or 8MK2 4 ohm stereo.

Just use nice external, analogue limiter/compressor before sub amp.

Ok, so you would prefer a 8001 over a ca12? do they handle 4ohm bridge properly?
5000vz probably a bit a risk of the occasion market and proline 3000 over all of them exept the inf8?

cheers guys, for all the feedbacks so far!

remember, proline has more output than the specs say!

Proline 3000:

Hersteller: 2x 1100 Watt an 8 Ohm
Messung: Sinus 2x 1250W/8Ohm, 12db Crest 2x 1550W/8Ohm, Impuls 80Hz 2x 1390W/8Ohm
Hersteller: 2x 1500 Watt an 4 Ohm
Messung: Sinus 2x 2100W/4Ohm, 12db Crest 2x 2200W/4Ohm, Impuls 80Hz 2x 2020W/4Ohm
Hersteller: 2x 1800 Watt an 2 Ohm
Messung: Sinus 2x 2300W/2Ohm, 12db Crest 2x 3000W/2Ohm, Impuls 80Hz 2x 2874W/2Ohm



or what about SAE PXM 1450 or PCM 18 ?

Would think test figures for 40-50hz would be of more relevance here.

There are a suprising number of people with Broken Proline 3000, that can't be fixed, after being told they were good for 4 ohm, 2x18s per channel, on sub. Wink

yeah, but it seems that the clipping circuitryl isn't very accurate, so I don't want to take that risk, even if pd1850's can take probably a bit more than v1000's, don't you think?

Yes, absolutely, if proline 3000 I would anyway go with 2 for 4 x1's.
So two second hand 8001s or two new prolines?

personaly i would say anyone who rates the 5000vz for sound quility is either a lover of distortion or completely death ..... maybey im too anal but realy? i had two ... hated them so much i replaced with 4 pv2600s wich i also hated i know this is a crap comparison but realy? and the same person rates the crown itechs? as muc as i hate them but i prefer berry europowers to the crown itechs lol just an opinion but hey check them distortion figurezss!!!!!
If you want people to feel the bass then a reflex design is probably best as you get the most air movement per decibel from those.      errrrr yes wtf?
