Hi All, After the successful event I have noticed that the aluminum plates were worm, not hot but worm, is this normal? I guess it is, concerning that driver went is shooting directly to the ALU plate. |

Hi All, Finally i have finished my first two Labs. Yesterday they were playng on a Psychedelic Trance party with some DJ from France and for around 400 - 450 audience. They were driven with one Crest C12 - one lab per channel and amps were just tickling the clip lights from time to time. Two weeks ago I was doing the same place, same audience, same music with 4 RCF Vision 18" and same amp. The difference was really noticeable. Not that much in power but in the clarity of sound and the octave plus below the RCFs. Labs was placed approximately 10m(30ft) wide form each other and on their side layed on the floor with bottoms faced toward each other. Considering that they were fed with badly processed signal (some fool locked the DSP unit and we were not able to properly set the low and high pass filters for the subs) and also no delay to the tops so i had to place them little further back and aside to compensate a little. After the successful event I have noticed that the aluminum plates were worm, not hot but worm, is this normal? Hi Marjan, Just shooting from the hip I would first note any differences from typical use. You mention that the xover might not have been set properly, but you don't say exactly how it was set. Was the xover set higher then normal? More bandwidth will show up as more heat. Perhaps not enough to be obvious, but it would be something to look at. Any kind of compression. Rave music in general is highly compressed material to start with compared to pop music in general. Lastly running anywhere near clip (i.e. near or above what the amplifier power supply is capable of) is another form of compression. BTW, does the C12 have on board limiting? If that is engaging we have an even higher average power level. I'm not saying you are doing anything wrong here, just looking for likely causes for a little extra heat. Too Tall I guess it is, concerning that driver went is shooting directly to the ALU plate. So if the cash allow, I will soon build another pair. At the and thank you all for making this forum as it is an to Mr. Danley for sharing the plans with us. Regards MarjanM |

[clip] Those boxes are damn heavy. I didnt have time to put any handels or weels so it was dificult to lift them and carry to the stage. Lets ask Mr. Danley to invent some antigravity device to carry our equipment. [clip] |
