AVR for LSis

You know what's really cool? Is when you realize that a loudspeaker will actually operate with ANY given wpc. Not everything has to be reference or concert level to sound good.

In regards to LSi, certainly, quality amplification is a benefit to ANY loudspeaker. That being said, feel free to stop by and let my lowly HT AVR drive the crap out of your LSi15 or LSi25. If need be, I'll get a pair in-house so you can flip-flop in person. Hell, bring and amp and we can have fun and argue about why none of this actually solves anything. I'll still send you and your mangina home with an excellent experience and a full stomach.

Who are you referring to Doro?

I have a question. Who here has actual experience driving LSi's with an AVR? Of those with experience, who had trouble, and felt that the speakers sounded inferior to RTi's, Monitor series, etc? Who had problems with their AVRs kicking off?

Those who have had trouble please state what AVR, and LSi's you were using.

Thanks

I didn't like the sound of my AVR (in my sig) driving the LSi15, LSiC, and the rears I have. I had the B & K at the time, but I wanted to see the difference.

I wasn't using much of the speaker only driving it with my particular AVR.

Me, Me, Me!!! Actually, I only ran the 7's and 9's off of an AVR as an experiment. The Oink has pretty good power but it ran hella hot and sounded like crap (comparatively) to the Carver amp.

I would definately say that my RT800's sounded better on the carver amp than the LSi's did on either the Kenwood or Oink AVR's

Agreed w/Mark....I think that in some cases we get a little to wrapped aound the axle about certain issues.

I ran my LSi9's on a Carver receiver and my SDA's on a Denon HT receiver....with zero issues.

I've only had my LSi's on seperate amplification. I have improved amplification while I owned the Lsi's, and as I have said before, the Lsi's rewarded me for it. a strong argument can be made that this would be true for almost any speaker at a variety of quality levels, but in my experience, the improvement shown by the LSi's were quite pronounced.

can they be powered by AVR's? sure they can. IF the budget is kosher for a good quality AVR and LSi's, then go for it. the only caveat is that somewhere in the future, you will want to upgrade amplification before you upgrade speakers. I say this because I maintain that you should give the LSi's a chance to show you all they can do. I did, and am a happy content camper in the theater department for it. For the first time, I am feeling a level of contentment I have not had in this hobby. some will call that opinion, in my mind its pretty much fact.

if you go AVR, I would say it should be a damn good quality AVR. I know Carlos's Rotel got the job done, and I saw Doro's B&K, you know that thing could get the job done. I would avoid the lower end recievers, but that might be a moot point since they are usually not 4 ohm kosher, so it wouldbe ill advised from that standpoint anyway.

dorokusai

That's what I was trying to convey, as you can't use a blanket statement like AVR's suck or are inadequate. If so, you include Anthem, B&K & Rotel for example, and that gear is not low-fi.

I don't know that anyone said that no AVR would work. The person who started this thread indicated money was an issue. So, I doubted he was looking at high end AVRs, and even then, I'd still rather have an amp with that AVR.

bbeacham has consistantly taken the argument out of context.

Low Money
Cheap AVR
LSi15s

That's what we're working with. If you're not going to buy an amp for them, the AVR is going to run hotter than hell and you run the risk of ruining something, which is why I ask why buy the LSi15s if you're not going to even remotely tap into their capabilities.

That's all. Not really an argument about whether or not expensive speaker wire makes your system sound better -- just some simple truths based on a lot of experience.

Lots of folks asking advice getting all bent out of shape when they get it.

I'm sure than sunfire cinema grande or nad 773 receivers would make the lsi's sing

Go to the flea-market and buy shizelbs' Sunfire amp. It's a bargan.

JimBRICK

yeah that sunfire is an awesome amp. I wish I had the cake to buy it right now but I have to much on the go right now

The LSi7's are by far the easiest of the LSi line to run so yes - your AVR will drive them just fine. If you are really interested in 2 channel, a cheap amp and 2 channel pre-amp (total cost if you purchase used should come in under the retail price of your Onk) will sound loads better - but you will be able to run LSi7 with your onk just fine.

The original post wanted to know the "Best AVR for LSi 15 & LSI 7s in rear?"

The only "argument" I have dealt with is with those who constantly lump all AVRs into one pot, and all seperates into another pot.

I use an AVR (Sony STR-DA7100ES) with my LSi 15s (4) and LSiC, and love it. Generally, the SPL meter is reading in the 80-90db range for action movies, but Friday night, out of curiousity and to many beers, I decided to open it up with Guns and Roses. At 110db (multi-stereo mode) it sounded great, but was to loud for my taste, not to mention my neighbors.

However, according to many that is impossible since LSi speakers cannot work with AVRs. As others have said, any speaker will, more than likely, be better with better electronics, but that does not mean that until someone acquires the better electronics they cannot enjoy that speaker.

I probably will get seperates some day, but a 70" TV is my next big purchase. The current 57" has become to small. I never realized that TVs could shrink.

Best AVR for LSi 15 & LSI 7s in rear?

Post #5

Then the LSis aren't for you. You really need a separate amplifier so it can focus on powering the power-hungry LSi15s.

Post #11

Not to say an AVR won't be capable of handling these, but they really are meant for separates.

Post #17

AVR's will not drive LSi's. Seperates are THE way to go. Actually AVR's won't drive RTi's too well either. In all honesty seperates are the way to go with all HT speakers.

Post #26

OK fine, you drive LSi (4ohm) off your receiver instead of a pre/pro and amp and report back and tell me how long it took for you to burn up your receiver or fry your speakers.

Post #40

You're better off just sticking with inferior speakers that don't feed off of amplification if you don't want to give these speakers the power they thrive off of.

So, no, it's not a must, but I'd venture to call it a little bit insane to run the LSi line without amplification, especially a full 5-channel system.

Post #46

Play them too loud & the receiver will go into protect mode & shut down. Play them so that it won't stress the receiver & you will have to sit on top of the speakers to hear them.

Post #62

If you're going to insist on staying with an AVR and not upgrading to an amp down the road -- get different speakers.

Post #70

Just about every LSI owner has come on & confirmed that the more power you give these speakers the better they will sound. Power costs money. If you don't want to spend the money, get less demanding speakers.

Post #76

No, I think it wouldn't make a lot of sense to shell out for brand new LSi15s and drive them with only an AVR.

Post #81

Are you of the opinion that LSi's don't sound as good as RTi's when powered by an AVR? If so, I totally agree with your advise here.

Post #113

Those who choose to remain ignorant even after hearing the truth deserve whatever they get as far as damage to their speakers, equipment, or simply never discovering what their speakers are capable of sounding like!

Thanks for the info,I picked up the LSI7's today. Have one question, what gage speaker wire should I use. Right now I'm using 18 gage. Love these 7's.

Thanks
Dex

michael_w

Dex,

The 18 will work fine for now but you might consider getting something a little bigger. If you stray from brand names (as in go to home depot for some 12awg inwall) it's super cheap and gives you a good chance to try something new. Just make sure your receiver can handle the larger gauge before going and buying 50feet of the stuff. I've found getting anything over 14awg into an average receiver is a pain in the **** unless you tin the tips (heat them up with a soldering iron and let a tiny bit of solder hold the strands together just at the tips).

You'll probably hear a lot of people recommending the usual brands such as audioquest, signal cable, bluejeans, kimber etc... for low budget cabling but at this point I think your money would go farther if spent towards electronics.

Maybe create a different thread to post your impressions of the 7's and it'll make it easier to direct advice to you and keep this one on topic.

Yes he did. Josh said it right in post #17:
"AVR's will not drive LSi's."

my onk is working fine with the 7's, I just changed the impedance to 4 ohms. Onkyo TS-SR804
