Genesis 1.1, Infinity IRS V, 4 chasiss speakers

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.

Ekovalsky,

Do those Tact Audio S-2150 amps give you enough serious muscle to drive those woofer columns to serious chest thumping bass?

Man, those are some awesome looking speakers!

Mitch4t,

The answer to your question is not really. The S2150 are definitely not suited to a sub-2ohm load and when I have them driving the sub towers, there is loss of SPL below 30hz. The sub towers drop to 1 ohm at 19hz.

Ideal amp for them is the Crown K2. Massive power and awesome damping factor, plus plenty of power to 2 ohms and below.

I am temporarily back to using the 2150 on the subs because the DAC card, which had been driving the Crown K2, is now being used for a hybrid power amp I am auditioning (Blue Circle BC204) on the main channels. It is a superb amp, and it will probably be hard to go back to the S2150s on the main channels.
