Hi guys: I´m from Brazil and buy my amplifier Emotiva XPA5 in Jan 2013. It’s a awesome amplifier! Congratulations for this! In this moment I using four channels for biamp my front speakers, one pair Bookshelvs Energy RC10. This speakers are 8 ohms impendance. Now, I like to buy one pair large floor-standing / tower speakers for substitute that bookshelves. Is possible biamplifier 4 ohms impendance towers speakers , like Monitor Audio Silvers series S8 and S10 too? (see this manufacturing link www.monitoraudio.co.uk/products/silver/silver-8/). Or its possible to damage my XPA5? Thanks for de answer and sorry by my english |

Yeah, ok, the proper answer is yes.
Yes, the XPA-5 can drive 4 ohm speakers safely.
Yes, you can bi amp 4 ohm towers, very nicely, with the XPA-5.
Yes, you can damage an XPA-5. But hooking up unmodified commercial speakers shouldn't do it.

It should be stable for sure. Those Energy RC-10's are sweet bookshelves by the way (from the days of yore before the Klipsch acquisition )

Really guys? Absolute sure no damage XPA5 in processing?

It's a waste to passively biamp those speakers. They're efficient enough and you're not gaining much if anything by biamping. The passive crossover would just dissipate the extra energy as heat.

Am I missing something about bi amping a 4 ohm speaker? Wouldn't that give a 2 ohm impedance?

Sorry, but I discorded. I feeling difference in biamp use. I testing it using differents wires. At moment, I using Belden 5T00UP for "High" e Acoustic Research PR263 for "Low". The sound its more present e equilibrate than another single way, because my receiver Pionner Elite VSX32 really active 4 channels for that(L,LS, RS and R). And I use 4 RCA cables for preouts connection to XPA5, not two "Y" cable; so, in this case, its a active mode. I preffer this way than using Single mode using Kimber 4T for example. The sound is big different; using 4T + PR263 is much better for only 4TC too.
If a have using a Marantz AV7701 processor for exemple, its really does not difference because the AV7701 its not use a true biamp channels, only emulate that (passive mode). Also, the temperatures of XPA5 not variable.
Sorry again for my terrible english.

Ops!! I mean "desagree", not "discord". I write wrong word.
Thank you guys.

Hi, I really found that biamping really improved my sound too. I'm impressed by what my passive biamping has done.
Don't worry about your english, we can figure it out. We're glad your here.

Thanks for words.
Emotiva send me a pdf for XPA5 Gen2. After read, I see in pg 15 (specification) minimum impedance load recommended load: "4 Ohms; which equals one 4 Ohm load or two paralleled 8 Ohm loads"
In this case biamp its a paralleled mode, don´t it? Thats a question. If this correct so I thing, its no possible do it when 4 ohms speaker.
In panel rear of Marantz integraded model PM8004/8005 and PM11S3, system A or B accept 4-16 ohms, but system A+B only accepct 8-16 ohms.

The bi amped speakers will see 2 ohms which may or may not sound great and if it dips below its 4 ohm point which it usually does the amp may see 1 ohm or less and shut down. I don't think you'll bust anything though |

I agree. So, maybe a possible solucion is a MA Silver S6 because its a 8 Ohms speakers.
