Never expected both ends of the spectrum when I made that comment ..you want to solve this problem then I suggest redesigning the power transistor! Efinque. You many want to look that up again AB are awful when it comes to eff% Vicktor. Stop scare mongering... distortion on the current entering the PSU being a problem? I suggest building your own power station. And current being out of phase on ANY type of AC circuit it just one of those thing inherent in the system. It won't trigger an apocalypse. Less caffeine mate and try to get out in the sun a bit more. I love SP. You guys remind me I could be a lot (mentally) worse off... |

Agreed... but my wife does her best to keep me inline. I'm not sure I'm cut out for the 21st century. To much nonsense everywhere forced on you on a daily basis. So.......... back on topic. ...sorry

Small medium at large!! Yeah, I don’t know what that means either, but it has been a **** of a few weeks and my brain is fried. And now I’m going to sleep to forget all about working with w***ers!! |

Dave has world class DSP in his amps for a few years now I'm all about headroom but if you get a huge amp, even on a driver with this high AES rating, and you don't limit it and filter it properly then be prepared to smoke some coils. For that reason, if you don't have a SERIOUS DSP and know how to use it, you'd be better off with K10, or K20 with DSP, or a Linea 44M20, or XTA APA4E8 plus paying someone to actually measure your driver in cabinet to calculate the long term RMS rating in volts and the heating threshold of the coil.

From the pre-dsp days, many of us would train our ears to detect any issues taking place throughout the event. Although, Aphex Dominator was common in those times, many still gauged the levels based on common sense. I would imagine this is why I over power all my speakers.
One of the biggest issues I’ve seen are those trying to cover a venue that requires 8 – 16 bins and expect to get the same output as 8 – 16 bins using 4 boxes. No amount DSP protection is going to prevent loudspeaker failure if the user is reckless.
Sophisticated DSP protection is very helpful however, should never be looked upon as “My DSP is protecting everything so I can raise the fader higher.” Continuous average levels that offer a minimum Average to Peak Ratio can damage a loudspeaker with an unclipped signal just as fast as and amplifier being clipped to the point the clip light remains on like a light bulb.
If someone is investing in four Eighteen Sound 18 TLW 3000 speakers, they are supposed to be familiar with every means of precautionary methods to prevent any loss in their investment.

We are now running 4x 18TLW3000 drivers on a Powersoft X4. One bridged channel for one double 18" cabinet. When we build two more subs, we will be running 8x 18TLW3000 on the X4, this time unbridged channels. Not optimal regarding headroom, though. We have our eyes on the X4L in the distant future, but we'll build some more cabs first. Maybe we should look into some other type of cabinets for efficiency, let's see.
