o2so Posted February 21, 2017 Share Posted February 21, 2017 What happens if I run 2 pairs of 4 ohm speakers at the same time from my NAD M3? I don't think it can drive a 2ohm load. I tried briefly and it worked fine. I imagine it will overheat and shut down if I kept it going? Thanks!

Telecine Posted February 21, 2017 Share Posted February 21, 2017 The audiophile police will come around and arrest you. They will also confiscate your gear to distribute amongst those who follow the true path. 1 Link to comment Share on other sites More sharing options...

expat Posted February 21, 2017 Share Posted February 21, 2017 (edited) The NAD M3 is rated to put out 700W into 2? at max dynamic power though continuous output only rated 180 into 8 & 4? so probably could cope if you don't completely wig out on the volume. NAD were always famous for good current delivery. http://www.stereophile.com/content/nad-master-series-m3-integrated-amplifier-specifications This is what I get from Maggies. I have a set of 1.7i's and a DWM bass panel. They are both 4ohm speakers run in parallel off one set of speaker terminals. They are fed off a Burson Timekeeper which gets very hot and occassionally has a hissy fit and shuts down if volume past 11 o'clock. Just got a second TK and am planning to to go bridged mono - 240W/ch vs 80. Can do it but need an amp stable to 2ohm with a stiff power supply and plenty of current output. Bill McLean runs 20.7's and 2 DWM off PS Audio BHK amps. Edited February 21, 2017 by expat Typos Link to comment Share on other sites More sharing options...
georgehifi Posted February 21, 2017 Share Posted February 21, 2017 (edited) Quote Running 2 pairs of 4ohm speakers If your running, the Magneplanar 1.7 (2ohm min) and ELAC 244.3 (3.3ohm min) in parallel, then yes the NAD will be doing it hard at loud levels, just monitor the heatsink temp with the palm of your hand, if you can leave it there without discomfort, and the Nad's protection circuit doesn't trip, it should be OK (just). If there is problems, consider running them in series, if you don't want to get a new amp that can easily handle this paralleled load Cheers George Edited February 21, 2017 by georgehifi Link to comment Share on other sites More sharing options...

georgehifi Posted February 21, 2017 Share Posted February 21, 2017 That's why I said consider, worth a try as the load min will become 5.3ohm instead of 1.3ohm. Cheers George Link to comment Share on other sites More sharing options...
Guest Posted February 21, 2017 Share Posted February 21, 2017 This sort of thing is (or used to be) done in Car Audio with specialised amps that run large currents and are suited to 2 ohms or even down to 0.5 of an ohm. Expect lots of heat and current draw from the power supply in the NAD Amplifier Personally wouldn't do it as distortion and clipping would be the worst symptom of the parallel arrangement. Recommend bi amping the 2 pairs of speakers Link to comment Share on other sites More sharing options...

Cheers George There are amplifiers available that can easily deal with such a load. Link to comment Share on other sites More sharing options...

Andy No, all you do then is get more wattage, but less current ability and damping factor and stability. Cheers George.
