Axiom Home Page Forums General Discussion Technical Questions Amplifiers for the LFR speakers

Ok, I have been running these two mono's for over two hours playing around 69 or 70. Reference is too loud for my room which is 82 and NO heat, nothing. Room temperature?

I will really be liking these units in the summer,whoohoo!

Thanks for all the info guys. We had a grandaughter that was born on Wed and our daughter called right after my last post this morning and had to rush to the hospital. The new baby has some posible heart problems so we have been there all day. But looks like it is not going to be as serious as we first thought. So makes this audio stuff not quite as important.
Anyway, yes I have already ordered the LFRs. Not opposed to used stuff, but I have been burnt on Ebay in the past. Not saying I would not go that route. The first ones you mentioned have now gone on the bidding instead of the buy it now so will see how it goes.
Looks now like the Outlaws may be the best option after the response from Sbrown.
I have read some reviews and thought that maybe the Emotiva problem may have been fixed, but if I went that route would take the advice and wait until time for the speakers to order that.
Thanks again for the replies. Will let you know what I decide.

Best wishes for your grandaughter, Steve.

Steve, best luck to you and yours. Glad to hear that it's not as serious as you first thought. Hang in there.

Thanks for the well wishes. It is our youngest daughters first. The hardest part was seeing our baby so upset. But like I said, looks like it will be ok. We know more tomorrow once all the tests are back.
Thanks again.

dakkon, the second amp you mentioned on Ebay was sold at 5 this afternoon. Was not home in time. I will keep an eye on the other one and see how the bidding goes. Would like to stay under 2000.00 total for the amps.

Hope the tests come out well...


I agree, having spent 6 years in the military you learn about priorities..


Let's make sure you get the correct amps for your budget that will give you the maximum performance.



I have gotten burnt on ebay before as well. However, all of my used audio transactions have gone quite smoothly.


Darn, that's to bad, the seller had a buy it now for 1,000$....


Honestly i am not sure if Emotiva has gotten their problems fixed or not...



Just wait until Mark finds this thread, he is going to be sooo jealous.... It's gona be GREAT...

P.S. Steve, how many total channels of amplification do you need? do you have a 5 channel setup, or is this going to be strictly a 2 channel system?

Hey dakkon, I retired from the army. 28 years.
I have a 7.1 setup. Using an Onkyo 3007. I will use it with my amps. I really only need amps for the LFRs. I was just thinking about using an additional amp for my 180 if I went with the monoblocks. Then use the Onkyo for the surrounds. But all I have to have is the 4 channels for the LFRs.

Steve, your understanding is incorrect in part. As Andrew pointed out about a month ago, there is no "equal amplification" requirement. The max power ratings(if different amplifiers are being used for the back drivers and the fronts)can vary widely, as long as both are sufficient for the required sound levels. Andrew suggested that the amplification for the back drivers would be sufficient if it was about 60% of that available for the fronts. The important factor was that the gain(a fixed factor)was equal for the fronts and backs so the intended front/back balance could be maintained. This would be the case if a HT receiver or separate amplifier with identical channels(and say a 100 watt or more maximum output capacity)was used. If a setup with different amplifiers with different gains was used, some level control to correct for the different gains would have to be used.

John, i e-mailed Andrew about this.. At the time there were 3 different amps that i was looking at, the variation in the gains were 0.6DBW from the amp that i already had. Andrew said that .6DBW would an acceptable deviation, but identical gains would be ideal.


The amps that i will be using have different power ratings.. The amp for the fronts is rated for 600W @4ohm, and the rear channels will be powered by am amp with a rating of 500W@4ohm.

Where have you been John? it seemed like you disappeared......
