Back to the future or return from the future to the present ????   4 comments

BTTF

So anybody remember that movie BACK TO THE FUTURE ? One of my most favourite scenes next to the “this amp goes to eleven” from Spinal Tap is the scene where Michael J Fox blows one of the biggest loudspeakers in this world to bits . The story tells about a guy travelling back & forth in time in a delorean sports car . The car is a time machine because it has a FLUX-capacitor build in . Because of power problems it needs a lightning strike to get back to the future . So what does “BACK TO THE FUTURE” have to do with audio ? Lees de rest van dit artikel »

Why even bother ???   1 comment

In the last few posts there were descriptions of cardiod sub array’s .

Turns out you need more processing and amplifiers to build them , knowledge to put them to good use (so you need a system technician) , measurement equipment for verification and calibration and a number of other things so in the end it all comes down to money . These set-ups are more expensive . Lees de rest van dit artikel »

End fired Sub array (only in English)   3 comments

I did a article on End fired sub array’s more than a year ago but only in Dutch so now the English version . The end fired sub array has the advantage of summation in front of the array and cancelation at the back of the array . It needs in a 4 element array 4 amps and 4 processor channels where you might need only 1 or 2 amps and 1 channel of processing in a conventional stack of subs . Lees de rest van dit artikel »
