I'll be sure to setup the other tomorrow for an afternoon 3 some cool.gif

In all seriousness, I am probably going to see if I can flip them on their sides and remove the feet to get them a bit shorter. That's still 6.5 feet side to side though, yow!

I believe I recall Tom saying that quite a few people do that. I look forward to seeing them set up as part of your home theater.

@prime316 we can get a collection going to buy you a real bed. biggrin.gif seriously though I have been dying to see an XV30 in a home setting to get a true idea.Thanks for posting your pics up. I have been wrestling back and forth on whether to get two V15's or one 30 (then maybe a 2nd one around XMAS time if needed, but I doubt it) my room is 12 X 25 9 ft. ceiling. my listening will be about 70% movies and 30 for music. let me know after you have listened to your system with the V30 which way you suggest I should go. I also looked at your other equipment. you have the Klipsch RF-62ii which are rated at 500W max just like my polk audio RTI A9's. the only difference in my system is that I plan on using a 2nd pair of A9's as rears. I am nervous after reading too many online posts that say an avr like the ones I am contemplating such as pioneer elite SC-68, Yamaha 3010 aventage, or onkyo 3009 (a little scared off this one for many reported hdmi board issues- not model specific, onkyo in general) that say 500W speakers can't be pushed nearly well enough without a dedicated Amp especially four of them. what is your take?

A loudspeaker's maximum power handling spec really doesn't tell you much about the kind of amplifier that you should use to drive it. I'm not an expert but per my understanding, you should really be looking at the sensitivity and especially the nominal and minimum impedance.

the a9's need a power amp no questions asked. the a7's are borderline...will a reciever power them sure, but not to thier capability. the xv30 is the size of 2 xv15's put together=huge!

@saviormachine, unfortunately I do not know nearly enough about electronics, sound specs, etc... to even begin to understand what I am reading when I see the numbers and analysis that everybody else here knows. I guess that I was sick the day that this stuff was taught in school. kidding rolleyes.gif

I know this wasn't directed at me, but a speaker's power handling spec will not tell you how much power you need, only their max handling capacity (short term). The spec you want to look for is sensitivity. I see your speakers are rated 90db by Polk, which is fairly efficient. I also noticed they are 8ohm speakers, so should be an easy load on the amp. You should have no trouble driving all four of your Polks with the AVRs you mentioned.

I use to own a pair of ADS speakers that were rated 90db efficient. I had no trouble driving them with a integrated amp rated only 35 watts! I later upgraded to a 100 watt amp and could drive them cleanly way louder than I could ever stand (and would also cause permanent hearing damage!).

Btw, if you are using a sub to handle bass duties, your main speakers will draw alot less power than running full range (bass reproduction sucks up the most power). With subs handling the bass, those AVRs will hardly break a sweat.

by no means is that an underhanded request for anybody to try and teach me this stuff. everybody here has more important things to do for sure. I just hope to get steered enough in the right direction to piece together a decent system.

seems kind of funny to set large tower speakers as small. but I can understand the principal of why this so. thank you
Add: of those 3 receivers I listed does anybody have a definitive best choice? I am searching for best video (including upscaling) least amount of drop off in power beyond the mains. those are the two most important qualities.

Agreeing with you, our mains have two each, 10" woofers so we're setting a pair of mains, with four ten inch woofers to small. As I'm sure you understand, Large vs Small is another way of saying, with, or without a subwoofer. biggrin.gif

Si senor. reading these forums I saw one of the funniest posts ever IMO. somebody had posted up- my neighbors 3 favorite movies.
1. 1,000,000,000 EXPLOSIONS
2. BUNCH OF ARMY GUYS YELLING
3. SUBWOOFER "THE MOVIE"

that was too funny...

Well, it isn't really, since most processors that perform bass management allow the user to choose Large or Full Range mains along with a subwoofer that duplicates the bass from the mains at a specified crossover frequency, a mode that's sometimes called Double Bass. Opinions vary on whether this mode should actually be used, but it exists and some people use it.

I only know about issues with Onkyo's receivers because I read about them here. I have owned two and not had an issue...knock on wood. My 809 drives all 5 of my speakers quite easily.

Hey, since you have experience with SVS. Which SVS sub do you think is on par with the XV-15 performance wise?

I realized long afterwards, but it was almost definitely improper forum etiquette to change the main topic thread of PSA subs (which I will be buying for sure) I should have sent a PM instead. sorry about the error.

Well, I only want to comment on the SVS and PSA subs I've owned, which are the PC12-NSD and the XS15. However, measurements at Audioholics and Data-Bass make me think that Fineberg may be on to something.

I envy you and Fineberg. Well, that's not totally true. I envy all PSA owners here!

Pretty impressive for the XV15, considering the respective price points of the 2 subs!

Been having my XV30 for about a week now. The only thing I have to say is that it's ridiculous! In a good way, Lol biggrin.gif

Don't mind my gear. Had to take the baseboard out to fit it in that cubby. Its a perfect fit and sounds great!

Is the rear port being blocked by placing it in that area??? Couldn't that cause damage to the sub?

I also think to my unprofessional knowledge that it would make the bass directional being 'holed' up in there, no?!?! Sub should be out in the open rather than 'holed' up.

How much of a gap is there from the port to that wall? It should be at least 4-6"

Congrats!
