Genesis 1.1, Infinity IRS V, 4 chasiss speakers


All 4 chassis monstrosities....seven and a half foot tall behemoths. Assuming the room is big enough for these speakers, what would be the optimum distance from speaker to listener seating?

How far apart should the two ribbon/tweeter towers be apart?
How far out should the bass towers be from the ribbon towers? How far out from the rear wall should they be?

I have a very large room and I would like an idea on what the configuration would be for optimum listening. I plan to make a complete makeover of my system in 18 months and I'd like to know how much room they would take up for optimum performance. Most of the photos of these speakers that I've seen seem to be in cramped rooms.

thanks,

Thanks for the info and pics on you system Rwd.....You are using tubes on top and SS on the bottom in a 4 chassis setup......any problem with the woofers and mid/tweet columns getting in sync using two different types of amps?
Yes......go to live concerts. Make sure you do not increase the woofers too much. We all seem to love the effect that a great bass system can produce....but in a live concert it is much more cohesive. Keep the woofers under control. A good bass amp and careful listening and adjusting your crossovers will help.
Array drivers need to be listened at a distance at least 2x the
height of the array. The mid/tweeter panels should be placed at least 3.5' away from side or rear walls, 12 to 15' apart, and 20' away from the listener. The woofer columns need a celiing a minimum of 12' in height. The mid/tweeters should have a 5 to 10 degreee toe-in.
I have owned(and miss)the Infinity RS-1b's/Infinity IRS-Beta's.I have,also heard the Infinity IRS's on a few occassions,as well as the Genesis 1.1's.I have been to Sea Cliff on one occassion(smuggled in,by a friend,when the owner was away.A lousy friend to the owner,but I wasn't going to pass on that opportunity).All set-ups will require the owner's ability to fine tune based on moving(a pain in the neck,and back)the speakers around.It will be,completely,room dependent,but worth it.In the Sea Cliff set-up,I remember the Infinity's were set-up in a fairly small room.The woofers were inside,and just behind the wings.There was absolutely no sense of soundstage,as we know it today.However,MAN,did it have dynamic range.Only problem,to me,was that it sort of sounded like a really clean disco/bar-mitzva/sweet 16 party system.Really!!Too small a room,regardless of the "HYPE",at the time!!Sorry,but true!

These types(4 tower)of designs,to me,require room to breath.They are IMO the finest type of system to reproduce any kind of "Truly believeable" musical presentation.The room should dictate whether one uses a Genesis1.1/ 201/350 or any of the older(less expensive Infinities).Although I have ventured away from this kind of configuration,I hope to acquire one again,in about 2-4 years.Based on my moving to a different location,at that time.I'm not about to move a big rig before that.Can't bear the thought!Also,Im thinking along the lines of Gen 201,hopefully,with a nice tube amp on top.

I currently have a dear friend(of very high Audio pedegree) who has been adamant about keeping,and refining through multiple mods,his "Classic" RS-1b's!He is a true lover of music,and I have to,and hate to,admit that as of now he has one of the finest systems I have ever heard!And,I've heard ALOT!!I consider the fact that he has refused to be influenced by "industry hype",and stayed loyal to a speaker "configuration" that his ears(and good ears,at that)told him was more truthful to the source,to be the main reason for such a high level of "TRUE MUSICAL" pleasure!Best of luck,and I hope you really DO get the speaker you want!
Take a look at my system with the Alon EGR IIs. My room is fairly small, 14.5' x 17' with speakers on the long wall, and the sub towers are in the front corners. Rather than use the provided DQ-LP1S crossover, a TacT RCS 2.2X splits the signal to the mains and subs with a DSP crossover and time/phase aligns the separate towers. Also it performs room correction below 200hz. It is a perfect device to use with a 2pc per side system, and I agree wholeheartedly that separate subs and mains are the ticket to ultimate musical reproduction in the home. With this setup there is no need to compromise between bass performance and imaging -- you get the best of both worlds.
