Panasonic has announced a big and colorful music system that can deliver 2,300 watts of crystal clear RMS oomph. The SC-MAX650 Extra-Large Audio System certainly lives up to its name, featuring huge 4-way floor-standing speakers with a prism color light show that moves and swirls in time with the music, and a rather chunky main unit built around full digital amplification in a tri-amp configuration.

Each 22 x 31 x 21-in (558 x 796 x 525-mm) speaker weighs 68.3 lb (31 kg) and houses a 15-inch ultra super woofer, a 7.87-inch super woofer, and a 4-inch woofer to take care of the mids to deep lows, and a 2.36-inch tweeter sporting a nano-sized bamboo cone that promises crisp clarity in the higher register. Three digital amplifiers feed audio to the giant speakers from the main unit. One looks after the super woofers, another takes care of the woofers and the tweeters get the remaining amp.

The main unit has dimensions of 19 x 9 x 14 in (485 x 231 x 378 mm), and includes an FM/AM radio with 30 presets, a CD player that supports MP3 playback, and a USB 2.0 port for playing tunes from a music-packed thumb drive. There's no Apple device dock, but digital music lovers can playback music from their preferred player via the 3.5-mm Music Port.

Included D.Bass with Smart Control auto adjusts the bass for more dynamic low end representation, while Maximized Bass Sound PLUS nips distortion in the bud, even at maximum volume. A microphone input also allows users to get in the karaoke party mood or interrupt the music with some witty banter.

Though not quite in the same floor-shaking league as the 10,000 W iNuke Boom iPod Dock, Panasonic's system is a whole lot more affordable at a suggested retail of US$1,199.99. The SC-MAX650 Extra-Large Audio System is available now.

A digital optical audio input would make this rig awesome.

Suspicious Chihuahua

$1200us and 2300wrms... speaker weighs 68.3 lb (31 kg) 15" ultra superwoofer 7.87" superwoofer 4" woofer 2.36" tweeter "nano-sized" bamboo cone(is it 2.36" or nano sized huh?) That amount of speaker and box would only weigh 31kg??? Do those speakers have "ultra expensive" "neodymium magnets" and the enclosure made in "carbon fiber"... or do they have Humdinger specials in them and a plastic box?


Just out of curiosity what in the hell does 2,300 watts of crystal clear RMS oomph mean?

That is the same type of nonsense that's published in various catalogs for the uninformed to state in a meaningless way, the "output" or "power" of the system.


The speakers look comparable to to maybe the Cerwin Vega VE15F http://www.cerwinvega.com/home-audio/floorstanding-speakers/ve-15f.html

It is a 66lb, 15" speaker with a 400 watt (peak power) sub. The 2,300 watt RMS is Panasonic marketing math by adding up all the individual speakers but from the spec sheet on the speakers the peak wattage for it is 330w for high and mid and 490w for low.

So ((3304) + (4902)) = 2,300


The following specs are from Panasonic's product sheet.

The 2300W RMS figure is the total instantaneous power figure causing a distortion or clipping of the signal to a level of 30%(THD) for the single frequency stated at 1KHz

2300W / Hi: 330W x 2 (1kHz, 3ohms, 30% THD) / Mid-Low: 330W x 2 (100Hz, 3ohms, 30% THD) / Low: 490W x 2 (100Hz, 2ohms, 30% THD)

The 920W RMS value is for the distortion figure of 1%(THD) over the frequency as stated below.

920W / Hi: 130W x 2 (400-20kHz, 3ohms, 1% THD) / Mid-Low: 170W x 2 (50-200Hz, 3ohms, 1% THD) / Low: 160W x 2 (50-100Hz, 2ohms, 1% THD)


Well, since you can only get 1800W out of a 120V wall outlet - does that mean it trips your circuit breaker every time you turn it up? Maybe it jsut dims the lights?

Oh - maybe it runs on 12 "D" batteries and puts out 1000W like the boom-boxes of old? (Their specs were totally fabricated) )

Also - I don't think you can claim RMS figures for instantaneous peaks - it has to be continuous.

Also the power figures just above are reversed - the highest power is always for the low frequencies.


level of 30%(THD)... hope they are joking?
