i emailed this question to harman intl:

Hi Eric,

The Overture 1 amplifier is not stable to 4-ohms. the driver it was designed to workwith had a DC resistance of better than 14-ohms. It developed 150 watts with the original woofer.

Regards,

Ernie Luedemann

does this mean that a shiva will work with it? the dcr is up around 11.6 in series.

thanx,

eric

To get the right resistance you would only need a resistor. But I can say that the amp did not put out 150 watts. I have a pair of Overture 1's. The amp probable runs about 40 watts to the speaker before it developes some mad clipping. They sound nice for easy listening but are not too great for high power.

you think that little difference in dcr would cause problems? dang. my question is, how in the heck can they rate it at 150, and it only puts out ~40 clean? i thought they were supposed to be [email protected]$$!
this has me thinking...:)
i wonder what a monitor would sound like if i used 2 av3's an av8 and the standard audax tweet that adire uses for a kit 81 and 281. :)

Companies put out all kinds of numbers. It's really bad in the car audio scene. No amp that costs 300 bucks will put out the 1500 watts its claimed.

no, but a $289 jbl 1200.1 will do 1320 easy at 2 or 1 ohm...not too tough to do, and it does it SOLID...those things are nearly bulletproof.

RMS is what counts-cant remember what it stands for. This is the average value of the sinusoidal wave(sin wave). The max value or the peak value of the wave is achieved for a fraction of the duartion of the wave and therefore is not important. My averaging all the values of the wave over the period we have the RMS power. BTW, voltage in our houses is actually 170V, 120V-RMS.

RMS power is something like .707 X (Peak Power).

Therefore, if they say the power is 150w peak-peak: 75w peak, it is therefore closer to 53w RMS.

Most 'cheaper' companies will give their power ratings in peak-peak(to look like more), whereas more highly acclaimed companies usually rate it in RMS.

Hope this helps,

Adam

RMS = Root Mean Square.

The square root of the average of the squares of a set of numbers.

so does anyone sell a DECENT narrow amp that can fit in a tower thats about 9" wide, including the sides of the box? so ID would be around 7.5".

thanx,

eric
