Just curious — Crown xls 5202 amplifier


I was watching a YouTube video on the Crown xls 2502 amplifier.  It is rated at 400 wpc at 8 ohms and only costs about $650.  I was curious as to what guts this thing has underneath, to create that kind of power in a slender cabinet.  But when the reviewer took the cover off, I was surprised at how little there was inside this thing.  There were 4 (what looked to be) filter capacitors, a small transformer, a small coil that looked to be copper and a couple of smallish heat sinks.  It didn’t look like anything that would produce that much power.

Do you know how this technology works?  If it is able to produce so much power in a small space, why don’t more manufacturers build their amps this way?

(The reviewer noted that such amps are used in commercial applications and this amp was noisier and did not produce as full a sound as some other high-end amps.  Still, I would think a lot of guys would want that kind of power for such a low price).

And that one myth has probably been the downfall of many systems. In the "golden days" (whenever that was 60'-70's )high powered amps were not readily available.  Oh sure. professional studios and venues had them . But the typical  PA' system only had 200wpc or less. I've sang over many of them. High wattage then was 60-80wpc. The key is that it was known that high watts doesn't necessarily have good sound. Today, I see people constantly talking about the "Need" for a high powered amp 300-400 wpc as though it automatically meant that it was going to sound better. FWIW, I have a 1200 wpc Crown in my PA. I've had 1200 wpc to 35 wpc (Which I have now) The 2 best sounding amps were 35wpc tube and a 45wpc Harmon Kardon. OK, I'll slide my soapbox under the table now and get out my flame retardant suit.
