Hello Kind Folks,
I know that the Conion C100 (45W), Clairtone 7980 (42W), and the Helix HX4635 ((28 W) are the same unit. But why, in order, are they 45W, 42W, and 28W?
As well does anyone know how many watts the JVC RC-M90 is? And the Sanyo M-X920?
I have been buying and selling and noticed that the Lasonic TRC 920 is to me the best sounding blaster ever - any comments? And, I've had the JVC RC M90, which is the only equal to the TRC 920 that I have noticed. If there is better, let me know. Cheers kind folk, Paul

Interesting.... I have all of them and can not tell a sound difference based on wattages....

The 920 to me is not the best sounding, but might just be my unit... Although it is in great shape.

Thanks for the input..

JVC M90 power:

20 + 20 w (40w) maximum (70 watts consumption)
I believe, but never owned one and don't have the spec in front of me so I could be wrong but I'm sure this was the JVC official power rating.

Although somewhere I'm sure I read the RMS was soemthing like 8.5w per channel into 6 ohms...

From what I understand, the only reason that the same box would show a different power consumption rating is based on where it was sold. Different countries have different regulations on how that is computed. There is no "volume" difference on an M70 that shows 40 watts power consumption vs. the one that shows 47 watts. The guts are the same, except for maybe the tuners (SW, LW, MHZ range, etc).

Incidentally, the back of my RC-M90JW says 61w power consumption.

The JVC M90 uses the AN7156 amp IC chip. The power output is 17 watts at 15VDC into a 6 ohm load at 10% distortion. The frequency where this is measured is 1Khz.

10% distortion sounds like a lot, but most people cannot detect (or are bothered by) 10%.

Since the box is stereo , the total power is 34 watts.

yup.
Remember, the power rating on the back is the power consumption of the whiole boombox, not the audio output power. That said, it can give an indication of sound output if you take into account CD players, tape decks etc. (a heavy duty servo deck will use more power than a simple manual deck).
...& finally, as mentioned above the other real fly in the ointment is the fact that power comsumption for exactly the same boombox can vary depending on it's country of sale. Canada seems to have higher power ratings on their stuff for some reason...

I have to agree with paulchris

The 920 really rocks!!!

Not sure if it's the best sounding box but it is

most certainly right up there.
