[#17] Onkyo 5009 贏左 Pioneer LX-90     
I am also an Onkyo AV amp owner (not the latest model)

I admit Onkyo top AV amp is quite generous on the power supply and the amplifier section. Yet it probably does not want to guarantee 4-ohm performances. Kindly note that 4 ohm nominal impedence implies that at some frequencies the input impedence can drop below 4 ohm. i.e. I believe there is still possibilities to activate the protection circuits. Of course, there are other dependencies, such as the room size, listening volume, the speakers' input sensitivity etc...

To push 4ohm without burning ur Onkyo amp, u need to apply setup in screen menu. But in bi-amp / bridge mode, 4 ohm is not supported.

Anyway, I tried to use 5009 to push a small Dyna 4 ohm bookselves. Yes the amp is not burnt, but the quality is far below expectation. Ghost power amp is highly recommended for those 4ohm users.

I think we should be fair to the AV amp manufacturers. Speakers with both low impedence (4ohm) + low input sensitivities(<89db) could be demanding to AV amp. Just a rule of thumb that 3db drop in input sensitivity implies roughly double amplifier power to produce similar sound level.

I am using Vienna Accoustic Maestro Grand (Centre), and Waltz Grand (rear channels). These are 4ohm and 91db speakers that live happily with the Onkyo amp in a spacious listening room.

前日去聽比拚會, 個場有五六百呎, 用 5009 推 9 隻 4 Ohm 82dB 喇叭, 5009 完全冇腳軟, 就算我自己用緊 5009 都吾信佢咁好力....仲以為佢地加咗後級
