horizontal lsi9's as center channel

snaabster

I have lsi9's as L and R fronts. I was thinking about using another PAIR of lsi9's placed on their sides (more or less end to end) as a very large and long center channel. They would be placed on 19 inch tall stands which would place the top of each speaker (which would in essence be one of the cherry veneer sides) just below the 65 inch picture screen. I would run them off a stereo amp.

Any thoughts anyone.

(PS - I could get a PAIR of used lsi9's for the price of ONE new Lsi center channel and I could not imagine a pair of lsi9's not trouncing a single lsi center; used lsi centers are hard to find)

Personally, I've read a whole bunch of articles in favor of using the same speaker for each channel. So, the merits of your idea are readily apparent-timbre matching, consistency, and the 9 would more than suffice as a center speaker.

My only reservations w/ the idea is that two speakers jimmy-rigged into one channel is overkill-one 9 would be just fine, and it wouldn't overemphasize your center soundfield, whereas two would. Second, why turn it on its side? Just put the 9 on a stand upright below your screen. I think that would work very well. If you have the cabality w/ your receiver, you could test out a good 6.1 setup w/ the xtra 9.

I would try one LSi9 first, and give it a try laying on it's side.

Personally, I have an R50 laying on it's side for my center to match my left/right main R50s (click in my sig for a pic). When listening to a stereo source in surround mode. The R50 supports the center image, instead of anchoring the center, like the other real center channel speakers I tried. It's a subtle difference, but I get a nicely blended front.

I'd only use 1 as well. I don't think you'd have any problem selling a single LSi9 here for someone to do the same; that is, if you don't need the other LSi9.

Yeah, cuz I'd be interested in buying the other one.

Yeah, me too. I would split a pair of LSi7's or LSi9's with someone so I could get a decent center channel without having to fork over the dough for the LSiC. I would be trying to match a set of 7's(black would be nice too).

A lot of people switch out the crossover in the LSiCfor an LSi9 crossover anyway(so why not get the LSi9 to begin with?).

One thing I forgot to mention, I hope the LSi9s are good with voices. A center channel for HT handles most of the dialog.

Watch some TV with just your current 2 front LSi9s, and see how they handle voices. This will give you a general idea how the LSi9 will work as a center.

From a symmetry standpoint the 9 looks like a natural lay-it-on-its-side center candidate to me... Only thing I'd check to be sure of is its vertical dispersion (when upright)...

One thing I've been noticing lately is standing above many smaller Polks gives me a sense of rising above the sound field. You'd think with a dome tweet it should not be an issue, but I hear a change I do not hear moving side to side... Could be the baffle...

Suggest you lay one or both of your exising ones on side and check it out before buying...

amulford

I don't know. The centers are designed for proper dispersion of that info. They are also crossed over specifically for their purpose. Cascaded taper array....

I'm sure it would work, but I think I'd probably use a specific design suited for the purpose.

Just my .02.

I'm also ready to split a Lsi9 for a center channel if somebody is interested.
PM me if anyone is interested and we can look for a deal.

Acousticsounddesign.com will sell LSi 9's for $620/pr brand new. No hassle, no ebay, just request it on their product request form.

There not LSi9s but I have a pair of RT55is as centers, I tried some different combos but in the end found the best was one either side of the TV, run them off the front channel outputs to get the slight angle just right for the image then run them both off the center channel out puts, the only thing is that would half the impedance and the RT55is are an 8 ohm speaker so only 4 ohm in the way I have them set up so in your case it would be 4 into 2 ohm but if your amp can handle it or you have a second to help out this is an awesome sound, I had a CS1000p before hand and can easily say what I am currently running now is quite a bit better.

Give it a try and see, good luck.

Also can run twin LSi's in series and increase the load from 4 to 8-ohm... 2-ohm is asking a bit much from any AVR....

okiepolkie

Tour, how would you wire them in series? Would this not mess up how the speakers are crossed over? The only way I can see to do this would be to wire the top posts in series and then the bottom posts in series.

EDIT: see next post...

Tour2ma

Wire the postive (red) AVR/ amp output to the first speaker's red post.

Wire the first's black post to the second's red post.

Wire the second's black post back to the AVR's/ amp's negative/ ground (black) post...

You can do this in a single run with jumpers in place or in a bi-wire loop with jumpers removed...
