Emotiva Mono Block ???

[TennesseeOutlaw]

It's been a long time since Ive posted, so please bare with me. I'm currently thinking of purchasing a pair of A9's and was wondering if i could use the Emotiva Mono Block to run both speakers. I know that the A9's have an impedance of 8 ohms and the Emotiva is 4 Ohm stable; my question is can I basically "bridge" (twist pos w/pos and neg w/ neg) without destroying anything. Would I get the 1000 wpc @ 4ohms? Basically the 500 watts a piece, or would I have to purchase two amps to get what I'm wanting?? Thanks a lot for any imput. :confused:

Mono = single

Could you probably do it? Yes. Would it sound like sh!t? Yes.....

You only have one signal path, so there would be zero separation of soundstage......

Just get the XPA-2 (be aware of the weird design of the binding posts though)

Excellent point. I never even took that into consideration.. I suppose I havent had enough cups of coffee yet this morning.. LOL Thanks..

Well I really want the headroom of 500 watts.. I suppose Im a little power hungry. I'll just have to get (2) of 'em.

The XPA-2 or even 3 will give you plenty of power. The fact that it's a standalone amp will be a huge improvement over any receiver anyways, so I wouldn't worry about that.

Even though the XPA-1 user manual talks about hooking up multiple speakers to one amp, I can't imagine why (its unclear in the manual) when your dealing with a monoblock which is supposed to be for a single speaker.

I would get the XPA-2. If you still want to you can get a 2nd and bridge each XPA-2 (I think its 1000wpc into 8ohms when bridged???? Not sure about how the wattage is figured out when bridging). You're best bet would be to contact Emotiva CS to be sure. They can tell you the best solution for what you want to do.

Just buy four of them and bi amp and bi wire.

:eek: Good Lord! You guys just LOVE making things more complicated than they have to be don't you!:eek::p;):confused::D

Thanks for the comments everyone.. Basically, what I am wanting is for the A9's to be getting the full 500 watts, I was thinking of the XPA-3 for my center and surrounds.

Speakers will be:

A9's - mains

A3's - surrounds

Csi A6 - Center

I know I should use the Fx series as my surrounds, but with the room I will be using, using bookshelf speakers as the rears on stands @ either end of the couch just seems to sound better. I have used dipoles before and really didnt get the outcome/put I was expecting. Thus, I replaced those with bookshelves on stands and I got what I was looking for. Additionally, I have no need or want for a 7.1 system, if that would make a difference in any advice. I'm also thinking of aquiring a SVS Ultra 13 sub to round out the system. I love tons n tons of bass. I use my HT about 60/40 HT/Music. Ive heard the Rti12's, and they were very capable speakers, and with everything Ive read the A9's step up the level quite a bit. I listen to mostly rap, hip-hop, some genres of techno (house, trance, jungle, progressive.) The types of music and movies I will be enjoying will be very demanding on both the speakers, as well as, the amplifiers. This is the real reason I want the 500 watts per going to the A9's. If any of my logic is incorrect, please someone let me know. Thanks again for all your help.

Just don't neglect the center, (which you won't be with an XPA-3) as the center channel is muy importante in HT. I don't know the exact percentages but something like 60-70% of the main sound is from the center??

I have an XPA-5 for my HT as it stands now and I think its sounds AWESOME in my space. If I were to step it up though (which I will be doing in my new HT) I would probably put the mains on an XPA-2 or two XPA-1's and and XPA-5 for the rest of the channels. If you only do 5.1, you could bi-amp the center with the extra channels or leave them alone for more headroom.

Headroom is great and all but you have to think about this as well;
Would you ever be cranking it up to the point where the speakers would need to pull the max rated wattage?
Do you have the room and AC power to provide to 2 or 3 or even 4 separate amps?
Adding a subwoofer and setting the crossover would likely decrease the power hunger of the mains thus adding more available headroom to the mix (and less demand on the amps).
