Wharfedale wx8 Ohms Specs

JAH wrote: Can somebody help The specs to this amp seem not to be correct as most amps that operate from 8, 4 & 2 ohm range have quite an increase in the RMS and watts the lower the ohms go. Here is an example of Crown amp which runs at 8,4 & 2 ohms. Here are specs of Crown xls2502 Amplifier  Crown Xls2502 Power Output specs:  2 x 440 Watts (8 ohms) Stereo 2 x 775 Watts (4 ohms) Stereo 2 x 1200 Watts (2 ohms) Stereo Here are the specs to this Wharfedale WX 8 amp. I think the 2 ohms spec rating must be incorrect can somebody help? At 2 ohms the rating only jumps by 40 watts this cannot be correct. Most amps increase considerably more in watts the lower the ohms specs go. Can somebody help what would the Correct wattage at 2 ohms be for this amp. It is also a really heavy amp which weighed in at almost 17KG without box. The weight specs are also incorrect at between 11.9kg with box on the Wharfedale user manual . The WX8 amp is nearly double the weight then the listed specs. The listed weight specs are not near the correct weight making me think the 2 ohm specs are also incorrect for this amp also. Can somebody help. See the chart below for the incorrect 2 ohm specs for the Wharfedale Wx8 & WX12 amp.  Both Models seem not to go up by much in watts at 2ohms The WX8 goes up by 40 watts and the WX12 goes up by 100 watts at 2 ohm load. Can this be correct? Could the Wharfedale specs be correct and some amps do not jump that much in wattage the lower the ohms go? Could it be the way the components are and the design etc? WHARFEDALE WX8 AMP OUTPUT SPECS 8 ohms 500 Watts 4 ohms 800 Watts 2 ohms 840 Watts WHARFEDALE WX12 AMP OUTPUT SPECS 8 ohms 700 watts 4 ohms 1200 watts 2 ohms 1300 watts After viewing many pa amplifier specs which run at 8 ohm 4 ohm and 2 ohm load they all increase by about 300 watts the lower the ohms go as in the Crown amp specs example. What is easiest way to find out if the specs are correct?

Running at 2 Ohms puts a lot more strain on the output devices and the power supply, which can shorten the useful lifespan of the amp. It also makes you much more liable to poor damping factor from the resistance of the speaker cables, and means that if you use it as your default modus operandi then you don't have anywhere to go as a backup option in case of one amp dying on a gig.

Jah... what the specs for that Wharfdale are telling you in an around about way is that the amp really isn't designed to operate at 2ohms and given this is an lowend brand it's possible the thing would overhead and shutdown or simply blow up if you try to run it hard at 2 ohms.

The Crown iT isn't really designed to run at 2 ohms either but this touring level amp will handle it without shutting down because it has a ton of safety features built in to accomplish just that.

Just average and they don't say anything about how the amp would perform at low impedances.
