audioguru said:The frequency response for the 4 inch mid-range speaker isn't shown.
It has very low sensitivity and a low max power spec so it will determine the quality (poor) of the speaker system.
audioguru said:One of the very good and powerful 8 inch woofers says that it works well in two-way speaker systems.
audioguru said:How well do "home" speakers that have a paper cone last in the high humidity of a car?
What car amp is designed to drive 8 ohms speakers?
How much power will cause the 20W Vifa mid-range speaker to smoke? Its sensitivity is also low.
Death By Bass said:How much power will cause a 20watt tweeter to smoke? it all depends on the crossover frequency, and they rate that 4.5inch mid at 60watts musical / 90watts max anyway, so, I imagine it could take a fair bit.
Death By Bass said:audioguru... what are you talking about? :s
"You know that a 4-channel "200 Whats" car amplifier produces only about 6 Watts per channel at clipping into 8 ohms per channel, don't you?"
huh? :S
Nigel Goodwin said:He was exaggerating 'slightly' about the largely imaginary rating of in-car amplifiers and speakers - a '200W' four channel car amp would be '50W' per channel, which is probably only 16W into 4 ohms, or 8W or so into 8 ohms.
Car amps (and speakers) usually have wildly exaggerated specs!.
audioguru said:Will your amplifier produce more than only 6W to 8W RMS at clipping into 8 ohms per channel?
Specifications:
Power / channel @ 4ohm 14.4V: 130WRMS x 4
Power / channel @ 2ohm 14.4V: 190WRMS x 4
Power / bridged @ 4ohm 14.4V: 380WRMS x 2
audioguru said:Most 3-way speakers I've seen have a woofer, a tweeter and the photograph of a super-tweeter that looks nice but doesn't make sound. Sometimes the super-tweeter is a cheap little piezo speaker that sounds like a whistle.
