Lsi9 Sounding too boomy and Muddy

veerapaneni

Hi, I am in the process of Replacing my RTi7 Series with LSI series speakers. I am still waiting for LSI15 to be shipped and in the mean time got old LSI9s locally which i am planning to use as back surrounds. For now I am using them as Fronts until i get my 15s. But they sound too boomy and muddy. The seller said they are 2 yrs old. I really did not like the way they sounded. I liked RTIA7 much better.
When i play the songs in surround mode, i like the sound of my new LsiFX better than old LSI9. Any comments?

My current Setup
Fronts: Lsi9 (Old)
Center: LsiC (Brand New)
Surround: LsiFx (Brand New)
Amp: Sunfire Grand Cinema 7~400
Receiver: Denon 3311CI

What type of comment(s) are you looking for? Is there a question in there somewhere?

Did you rerun Audessy when you moved the 9s up front ? You need to play with placement. Did you replace towers with bookshelf speakers ?

Yes. I have run Odyssey setup after changing the speakers. I replaced RtiA7 with Lsi9s and ran Odyssey after that.

I owned Lsi 9's and they need to be out in the room away from the back and side walls. They do have a little bit of a midbass hump built in to the x-over even when placed properly, but not as bad as you describe.

Just keep working with placement.

I have lot of free room around the speakers. Atleast 2 feet in all directions.

Hello,
Do you have the LSi9 speakers on stands? Or, do you have them, temporarily, sitting on the floor?

I have them on 30Inch Stands.

Also double check your speaker connections,at both ends. Do you have them set to small or large ? You may have to go into the set up menu,play around, and do it manually.

Check for proper phasing as well

As stated above, the LSi-9's are tilted up in the lower midrange / upper bass. Most of the times, this voicing is considered pleasing to the ears. However, it can sound a bit over done, especially under the following circumstances:

- If the speakers are located too close to a wall. IE: closer than 2 feet from a rear wall, and closer than 4 feet to any side wall.

- If your amp is unable to control bass. This is most commonly found with low powered tube amps - though in some cases this extends to big amps that already sport sloppy bass.

- If you are powering your LSi's by a receiver. Most receivers sound OK at best, and almost all of them suck at controlling the drivers on the LSi-9.

- If you are coming from a set of speakers that are super quick and agile in their response. (May be the case here, as the RTiA's are a bit more quick footed than the LSi's).


Also - playing songs in surround mode ain't exactly a good thing, especially when most recordings are mixed for stereo (two channel) play back. The LSi-9's may not be super linear, but they are resolute enough to tell you more of whats going on with the actual recording/signal than the RTiA's.

I was playing in surround mode to test my speakers. Otherwise i normally play them in Stereo Mode. I already have enough space around the speakers. And i am driving all my speakers with Sunfire 400~7 Amp.

Sorry. I am new to this. How do i do that ?

The guy you bought them from never messed with them did he? ie: take 'em apart to do anything to them. If he found his way on CP, he could have taken them apart to 'upgrade', changed something, or hooked the drivers up backwards (out of phase) when he put 'em back together? ...It's happened before.

Not Sure. He is a Construction Worker. He did not sound capable of doing this kind of stuff. Any way Once i get my 15s i will have base to compare.

So construction workers aren't smart enough to work on speakers?

I'm guessing he at least knew what making sure what wiring them in phase meant:rolleyes:

I am not here to judge anyone. I was just guessing since his field is different he might now know. Might be he knew . But how would that help me ? I am just looking for help.

How about a picture of your setup...

Thank You. I will upload them in the evening when i am at home. I just replace my RTIA7 and attached LSi9 and ran odyssey after that. The person whom i bought ran them on Receiver and never used Amp. I am wondering, that might have caused this. Just a Guess.

Where are you located?
There might be a knowledgeable forum member nearby who could drop in and give a listen.

Well to answer your question about your speakers being in phase: I'ts just about making sure that you are running positive to positive, and neg to neg in your connections from your amp to your speakers. If you cross wire these they are out of phase and could sound "off".

I am located in San Francisco Bay Area. Appreciate if anyone from this area can help me.

Yes. I am sure they are in phase. I am using audioquest cables and the cables are easy to identify with positive and negative.

Try the odd fraction method of placement.
Place them 1/3, 1/5 ,1/7 1/9th, etc., divisions of the room dimensions.
This will minimize room modes as much as possible via placement alone. This
applies to height, width, and length.

If this still doesn't do the trick, try taking a kitchen towel, and wrapping around the power port in the back of the 9's.

It could be that your room is very easily excitable, and some bass trapping might be in order. It could also be, that they aren't your particular flavor.

If you like the sound of the tweeters and mid range, the bass is fixable.

I have made some changes to my 2 Ch setup. Made My Fronts as small and set the cross over to 80. Now they sound wonderful in direct mode .

Way to go!

Are you using your receiver or an external amp to power the LSi9's?

The LSI line need beef dedicated amps, receivers just don't cut it.

Using Sunfire 7Ch Amp Which gives 800W at 4ohms

Do you have a sub? I didn't see that in the first post with your gear list.
If you do, what did you have the crossover set to before? You could have had the sub and LSi9's overlapping freq a bit.

I have Polk MicroPro 4000 Sub. when Odyssey set all my speakers as Full Rangeg, my receiver did not set any crossover.
