Lsi9 and LsiFX for Surround ?

tapeshc

I am trying to setup a Lsi setup with Lsi15 as mains, Lsic as center and Lsi9 and LsiFX in surround. Took me almost 3 yrs. to put it together

What I am not sure about is if I should use LsiFX in Surround or Back surround position.

Also if I should use them in Bipole or Dipole mode ?

This setup will be used for movies mainly but I plan to use it for SACD and DVD-Audio also.

I understand with so many factors affecting the performance, I should see my self what works best for my liking but a starting point will surely help.

Thanks in advance

Don't mean to hijack but what is the difference between bipole and dipole?

PS. Not the best to answer but I would think that the FX would be better as surrounds vs rears.

Lsi9

The FX sound fantastic in my buds hometheater his mains are LS90s and they are seamless. he uses a rear sub with his FX not sure if he crosses it over or not but the Fx sound full ranged and visceral
I used to own the older LS F/X, but they can't hold a candle to these "new" dipoles

Tapeshc,

I would place the LSiFx as the surround speakers. These speakers disperse sound better than the LSi9 giving you a more full HT sound field. That is what these speakers were designed to do.

In the back, I would place the LSi9s. The back speakers are really mono-channeled meaning that the same information will be sent to both speakers. They are the least important of all your speakers.

As far as setting your FX to either dipole or bipole is basically a choice you will have to make according which sound better to you. Typically you would use dipole for surround speakers if you did not have rear speakers. The Dipole effect causes the speakers to be out of phase using the walls and rear wall as a reflection point. Thus if you did not have rear speakers, you would get a rear and side effects and a very full sound field. Since you have rear speakers (the LSi9's) you can set the FX's to bipole, inphase, so that they will be louder and give more of a pressence (i.e., you do not need to compensate for the rear).

In the end it is up to you. However as a starting point, I would recommend:

LSi15 - Fronts
LSiC - Center
LSiFX (set to bipole) - Sides
LSi9 - Rears
Big nice subwoofer like an SVS 12" something to bring out the soundstage in a corner.

Any way you choose, you have a very nice system that you should be proud of.

Thanks a lot for your reponse.

I will start like this and then will make changes if needed, but your suggestion seems pretty logical so I think I should be all set.

Yes I am planning to get a SVS, cylendrical the PCI series, economical and seems pretty good. Cant get box as they weigh a lot and I am not good with heavy weights
