I looked at the stated technical data and I must say it looks like a good woofer! It has a very low qts but it seems to be a good feature for the tapped horn!
The simulation is really good, a little lower under 45hz compared to 15tbx100, but really cheap! And that's why I'm afraid: the power "of program" is like that of the b & c? that is, you can turn up the volume without problems? I do not want to assign 2000w, but 1400 / 1500w (high pass at 38hz) will it keep them or it will disintegrate everything? thanks for the advice!

If it sounds like a gorilla is trying to escape, turn it down.

Disintegrating a loudspeaker is minimised once you feed it a non-clipped-amplifier-signal. Of course, there are times when you can destroy a speaker with a lot of power from an amplifier that is not clipping its output. However, that usually falls in the realm of feeding a loudspeaker around 40 times its RMS power. Providing you know you are not going to clip the amplifier, you can get away feeding a 2000 watt program rating loudspeaker 1500 watts. High-passing won’t necessary make a world of a difference unless your tracks offer a constant amount of frequencies below 50 Hz. Protection from voice coil burn up lies in not having the amplifier constantly clipping. So a limiter is in order. Best Regards, |

I'm going to have to disagree with that Elliot, how many examples do we need 'round here to prove that this just isn't the case. IMO the program material makes more difference than anything these days, if the system will see nothing but compressed drum and bass for hours on end then you better limit at 1/2 AES of the driver or it's pretty much a guarantee the magic smoke will get out. If the music has some dynamics as in the level meters actually move then up that to AES, if the dynamics are even bigger than open up the limiters even further. That means if you're playing a variety then get amps capable of delivering the drivers program rating but clam that shit down if they go out on a jungle bass gig or the reigns will be handed over to DJ Redlight.

thanks, I use t.racks ds. 2.4 what time do you attack, hold, the decay advises me for the bass compressor? Can you use software other than the original one? Is the quality of the oberton woofer good? Are the declared powers real? can the original t.racks software be changed with a better one? Edited by Angelow - 12 July 2018 at 10:48pm |

I’ll have to disagree with you as well based on my experience. The only time pre recorded music becomes an issue is when the user is not happy until the amplifier is running into full tilt or they do not carry enough boxes for the job. There are also those that focus primarily on live events and dabble with pre-recorded events. Since their system is not designed for pre-recorded music their system tends to struggle particularly in the bass department (not enough bass bins versus their tops) and, end up with blown woofers. It is not the music fault if the loudspeakers were push beyond their limits due to not having enough boxes to get the job done properly at the event. That is the sound system engineers fault.

in fact, I remember the systems like the jbl hla, poor reflex on the bass and horn loaded on the m/h, unusable for disco

They both have similar cooling technologies:
Ventilated inner pole Ventilation holes between suspension and upper pole Ventilation holes in the middle of the back plate of magnetic circuit Same voice coil diameter + Oberton has 14mm high magnetic gap so should distribute heat faster from voice coil than B&C. Dont mistake it with dispatching more heat long term. Actually those 2 are a great examples to comparison excursion behaviou around Xmax as they have the same winding deepth and 12mm vs 14mm magnetic gap. Identical technologies including demodulating ring and similar ts.

So unusable that they were revered as the basis for the GSA system in Sankeys, you mean? |

I A /B tested both those drivers in my ported horns, the Oberton is a bit tighter and dryer sounding, cleaner, the B&C is warmer and rounder and a bit looser sounding, not quite as tight and defined, they measured close in my cabs but the B&C subjectively had a bit more extension due to the looser sound. It depends on what sound you are looking for but they should both work well in the tham 15.
