cerwin vega's folded horn design  :-o



Cerwin-Vega’s latest folded horn subwoofer systems utilize an incredibly efficient folded hyperbolic horn design. This enables the enclosure to contain a longer sound path  which amplifies the bass frequencies while keeping the enclosure compact in size for portability. The path length and flare rate delivers bone crushing low-end down to 30Hz.

The design of practical, portable bass horns has always challenged audio engineers because low frequency wavelengths are so large (e.g., 22.5 ft/6.9 m at 50 Hz) that they require a long horn. The challenge to reduce the horn’s dimensions without decreasing its length results in a technique that involves “folding” the horn. This technique collapses the physical dimensions of the horn without reducing its length by physically folding the horn within a cabinet.

saan available ito sir jef?

sir, as i was told, the pre-owned eaw sb1000/1001 subs were brought in from singapore to cebu but at an early dilapidated stage.  two models were taken in - the sb1000 and sb1001.  the sb1000 has two ports and between the two,  this sounded better (from the owner's feedback).

so the project will involve the sb1000 model.  the owner is talking with two suppliers- one from southern manila, and one from central luzon.   :roll:  i could not divulge the identities since this is still on a 'project' status.  hopefully,  we can have more idea on how much the local version will costs.  :-o

+1. Sir yung mga sales rep sa In Tune ay "Out of Tune" lagi.  :-D

It0 yung true p0wer rating ng behringer EP4000 power amp:

Output Power - EP4000

RMS @1% THD (sine wave), both channels driven
8 Ohm per Channel - 550 W
4 Ohm per Channel - 950 W
2 Ohm per Channel - 1250 W

Bitin pang subs it0 hehehe.  Ang 4000 watts ay kapag nAka "bridged-mode":

Peak Power, bridged mode
8 Ohm per Channel - 2800 W
4 Ohm per Channel - 4000 W

Hanap ka siR at least nasa 800 W at 8 Ohms per Channel at 1400 W at 4 Ohms per Channel.  :-)
