What is the XLS2500 wattage at 20HZ

The specifications :

Frequency Response (at 1 watt, 20 Hz to 20 kHz): +0 dB, –1 dB.

means that the frequency response of the amp is quite flat from 20Hz to 20KHz. 1KHz is only one frequency of the bandwidth.

So, what is the power at 20Hz? For the XLS, it is the same between 20Hz and 20KHz : 440W into 8 ohms.

Comparison : The XLS is a smps (Sample Mode Power Supply) powered device while the MA2400 uses a conventional analog power supply, with big transformers. As far as power is concerned, I believe the MA2400 is more powerful (505W into 8 ohms, 20Hz to 20Khz) but not by much. I also noticed the discrepancy about the 1KHz : The MA has a spec at 1KHz and another one for 20Hz to 20KHz. I must say, that power ratings for 'analog' amps can have weird ratings because of the way the power supply is built. With a smps, the power delivered to the output is more 'constant'.

Also, check the weight of the XLS : it is featherweight light! That should be a great plus for anyone handling a lot of MA amps!

Another question, can the xls2500 do and handle 4 ohm bridge like the Ma2400? I know two different people who run 2 sonic L36 cabinets (cerwin vega design) with RCF P300's in bridge mode. 2 bottoms 1 amp. Do you think the xls2500 is capable of this same senario. I'm thinking if crossed over at about 50hz the ohms my drop even lower and cause the amp to shut down. Hope this isn't true. Thanks in advance.

These are serious subs with big power requirements. Setting them up this way (4 ohm bridged) on the XLS2500 you would still under power them and put the amp in it's most strenuous situation. I have seen XLS amps shut down due to thermal protection so no guarantees here. I recommend you get a bigger amp or two and run it in a different configuration.
