Axiom Home Page Forums General Discussion Home Theater Is this enough power to push Axioms and SVS?

Hello everyone I posted this on hometheaterspot and recived some good suggestions. I also wanted to get suggestions from axiom owners.

The wife has Ok’d me to spend around 2500 on audio. This week I'm getting ready to purchase the following

Fronts Axiom M60ti
Sub-SVS PB10
Surrounds-Axiom QS8
Center-Axiom VP150

Tack on the new harmony remote and some cables and I have no room on the budget left. I bought my receiver the same time I bought the TV it’s a Yamaha RX V530. My question is does the Yamaha have enough power to push all these speakers. The specs are below and thanks.

Minimum RMS Output Power per Channel
MAIN, 20Hz-20kHz, 0.06% THD, 8 75W + 75W
CENTER, 20Hz-20kHz, 0.06% THD, 8 75W
REAR, 20Hz-20kHz, 0.06% THD, 8 75W + 75W
Minimum RMS Output Power per Channel
MAIN, 1kHz, 0.06% THD, 8 80W + 80W
CENTER, 20Hz-20kHz, 0.06% THD, 8 80W
REAR, 1kHz, 0.06% THD, 8 80W + 80W
Dynamic Power per Channel
MAIN, 8/6/4/2 95/115/140/160W

I listen to allot of concert DVDs ala Rush live in Rio! I also Watch allot of action movies and listen to rock and hip-hop. When the wife and 2 year old are not around I like to crank up the concert DVDs.

I sit 11 ft from the speakers in a family room 14'9"x 13', ceiling is 8ft

Here is a pic




The room is not enclosed notice the two openings next to the fireplace they lead to a huge living room with 20ft cathedral ceilings.




And also the room is open to a kitchen 13'8" x 20" directly behind it



I love open spaces for entertaining, but with HT it’s going to be a challenge.
Thanks again

75 watts per channel will drive them, but will it be loud enough? That is up to the listener. Maybe not loud enough if you like Rush In Rio (needs to be loud). I'd say try it out and see what you think. The sub won't require any additional power from the amp if you use the line level sub output. The sub will play as loud as it's internal amp will drive it.

Very nice home.

The M60s are efficient speakers so driving them will be no problem. The question is how loud do you like to listen? If that is 95+dB levels, that is where dynamic headroom comes into play. Excess watts give you great clarity even during peaks at loud levels. If you don't anticipate listening at those levels that receiver should work fine.

As far as the SVS PB10 that should work awesome for you. I have the PB12 and I almost think it is overkill for my applications. If I could do it all over again I would have no qualms going with the PB10. It's a great sub.

Happy listening.

Your current receiver will certainly be able to drive your speakers to loud levels. Whether 'loud' is loud enough for you is another question, though. You won't know until you have everything hooked up in your family room, so definitely hold off with a new receiver until you've been able to crank it with your existing Yamaha to see how it holds up.

Nice house, btw.

Tough call. The SVS is self powered so no problem there... but the Yamaha receivers don't seem to come close to their actual power ratings :

The room containing the speakers is pretty small so I *think* you'll be OK anyways. Make sure you have preamp outputs on the receiver then worst case you can add a power amp for the mains later if you want to play REALLY loud.

From what I remember the Yamaha amplifier stages are good; they just don't have enough power supply to drive 'em all at the same time, so if you offload a couple of channels to a power amp that gives the other channels a lot more power to play with.

My feeling is that as long as you run the mains in "small" (ie send the lowest frequencies to the sub) you should be OK. The SVS has a 300W amp so it should be able to keep up.

EDIT - welcome aboard, and I second the "nice house !!" comments

Welcome, stranger. As the previous replies indicate, it isn't possible to give a definite answer to your question. In the vast majority of cases a 75 watt amplifier is plenty. Those speakers will use about one watt at a comfortably loud average listening level. Split-second peaks will take much more, but wouldn't likely reach the 100 watt level unless you play material with a very wide dynamic range at a very loud average level.

Welcome Mr.

You should be good to go, the m60's are very easy to drive, and the other Axiom's your looking at, even a bit lower in ohm ratings, should not be a problem. If your receiver has an Ohm selection switch, leave it in the 8ohm position.

One other thing to consider to save a little $$$$, is order from the Factory Outlet from Axiom's Store page. You get 10% of the regular pricing, if you buy 5 or more items, you get another 5%. The Factory Outlet speakers are also brand new, NOT refurbished. Axiom has a high quality control manufacturing process, is there is the slightest blemish or nick, they get sold in the FO. Technically they are the exact same as the regular stock. Most of us will tell you we have never been able to find anything wrong upon a detailed inspection.

good luck on your purchase, I'm sure you'll love them

Thanks for everyone who replied. Based on the comments,It looks as though im going to keep the reciver. When I hook everything up and I need more power I can talk to the wife about a reciver upgrade LOL.

I will keep everyone posted I cant wait to hook it all up

Depending on how firm your wife, is on the 2500$ mark, if you can get her to go up maybe 200$. You could get m60’s vp150 qs8’s and an ep500 all FO.. and with the ep500 I think you would get a LOT more bottom end.. also don’t know how you feel about ordering from the factory outlet. But the axiom factory outlet is about the best you can get, when I ordered my ep600 me and 4 or 5 of my buddes all looked at the sub when it arrived and no one could find anything wrong with the sub.. just another idea…but if she is firm on 2500, then maybe forgo the sub for a little bit, save the left overs, and then go for the ep500 a bit later? The only reason I push the ep500 so much is the fact of the HUGE difference you will notice between the sub you have chosen and the axiom one. But in the end, it is your decision, and you will have to decide what you want to do..

That is a good point. The SVS will be a good match for your speakers with the current receiver, but if you upgrade the amplification in the future (the speakers will handle it) then you might start to hit the limits of the sub.

You probably will want a bigger sub if/when you get the bigger amp/receiver so might be worth going up a bit right now. Just a thought...
