Apogee Scintilla Power
Class D has to use a filter at the output to get rid of the switching noise. This filter has to be designed to accommodate a certain impedance. Pretty sure that 1 ohm is not a consideration. Most are set up for 4 ohms. Its not that the amp may not be able to drive the load, simply that the filter isn't set up to do its job on such a low impedance. Having heard this speaker with tubes, 'control' isn't the issue. |
Its really important to keep your speaker cables as short as possible when dealing with a 1 ohm load!! If ever there was an argument for balanced operation and monoblocks, this is it because you really don't want to have speaker cables be over about a foot or so unless they're 4 gauge or larger. The actual speaker connectors are important too as you simply don't want any DC resistances in series with the amplifier output. |
Other than the one ohm load, that speaker is otherwise reasonably efficient and easy to drive. The only time I heard a pair was at a reveiwer's house with our 100 watt MA-1 amplifiers using a set of autoformers to accommodate the load. There was plenty of power and it sounded quite nice. So if you wanted to use tubes, you could get a set of ZEROs (www.zeroimpedance.com) to help the amp out with the load. |
