“High Power” audio system, but yet no mention of the power. Even the Sony site doesn’t list the wattage.
The manual specs say 30W RMS per channel, but power consumption is listed as 45W.
Whatever happened to STEREO? I had loads of high end stereo equipment (Krell, Martin-Logan, Klipsch, Schiit, and others) back in the day. Then everyone went surround sound and got away from stereo, but now it looks like everyone is regressing to monaural.
I think you’re supposed to buy a bunch of these and link them together using partychain. I would buy at least 2. I think ultimately the idea with this line of speakers (there are several sizes and configurations compatible with this partylink thing Sony has going) is to set up a system through your entire home and yard without worrying about wires, amps, receivers, etc.
I think the only case you’d want just one of these is as a karaoke toy for children.
Link 40 of them up, you still won’t have STEREO. In stereo, the two channels have different signals. You’re just describing monaural with multiple speakers.
Well yeah but…
I see you beat me to that comment. What that says to me is (something muttered under my breath) crap.
But does it have a Radio Tuner?
The Amplifier section of the User Manuel says, "The following are measured at AC 120V-240V, 50/60 HZ. Power Output (rated) 120W (at 3ohms, 1kHz, 1% THD), 65Wx2 (at 2 ohms, 1kHz, 1% THD), RMS output power (reference): 470 W (1kHz)
I … didn’t even think of this.
It’s even worst than you think. Even if the manual was quoting peak and not RMS it just doesn’t come close to adding up. If I were to guess, I would assume the power consumption is probably the most accurate at 45W. Based on that I would guess the woofer at about 20 watts and each tweeter at 10 watts.
RefLib see page 40 & 42
Power Output (rated):
120 W (at 3 ohms, 1 kHz, 1% THD)
65 W × 2 (at 2 ohms, 1 kHz, 1% THD)
RMS output power (reference):
470 W (1 kHz)
Speaker section
Speaker system:
Tweeter + Woofer
Tweeter L/R:
50 mm (2 in), cone type
Woofer:
200 mm (7 7/8 in), cone type
Power consumption:
45 W
Exactly! You can’t get more out than you put in !!
[Preface - I’ve been in electronics for over 40 years, worked for Krell and Mark Levinson …]
At 100% efficiency (which does not exist), 45 Watts in = 45 Watts of audio. That’s TOTAL AUDIO POWER - split up between however many speakers …
This is probably a cheap Class-D Digital Amplifier that performs at about 75% efficiency at best. That makes about 33 Watts RMS of total audio.
They say the amp is capable of driving 65W into a 2ohm load but they don’t say what impedance the speakers actually are! They don’t say if the 65W is Peak-to-Peak, Peak or RMS! (RMS should be the only rating used to discuss audio power)
I loathe these kind of specs!!!
You had loads of schiit…hmmmm.
