Thanks!! My wife and I really love the look and sound.

I dont have a build thread yet but I will be providing Klaus Pohig information on the build sometime in the near future. Here is a start though.

They have worked very well in this configuration for over 20 years now. I bought both pair originally from a dealership and after a few months of thought and trial I took the plunge cutting the top halves off and combining them both physically and electronically. The passive x-overs are mounted inside the bass bins and the mid/hi panels are connected via wiring harness to the bass bins using connections that were originally on the passive x-overs. All wiring was replaced with monster cable. The bass bins are connected in series to raise the impedance of the woofer system. The emim's are connected as normal only 4 emim's in series instead of 2. The emit's are connected as they were originally. The mid/hi panels are constructed from the oak trim from the upper panel cover trim and mounting from the original panel for the emit's. Overall this has been an exceptional speaker system and paired with the Ampzilla 2000 mono amps on the woofers and the Acoustat TNT 200 on the mid/hi they play plenty loud with enough bass to shake the entire house sometimes with the fear of bringing the upstairs down :). They are in a 16' by 32' room and the listening position is about 18' from the speakers. I think even Arnie would like these.

Those look very nice indeed! Would have took a lot for me to cut them up though. That's just me.

So what is that smoking on the right?
 
Thanks,

It was a tough decision to cut them in half but the right one in the long run. They image great with a huge soundstage both front to rear and left to right. The bass is incredible. The "smoke" is just a humidifier running. it is winter and dry in Ohio :)
 
Hi Jim,

yes, I turned up the bass and the wall collapsed :D :D With 4 x 700 Watts from the P-600 this is not a problem :smoke::smoke:

Klaus
 
Awesome! It would be interesting to measure the wave propogation of the rearward firing emits and emims with all that thumping come at them!
 
Very nice Klaus,

I can appreciate the sound you get as I believe your RS1's and my dual 4.5's would sound very similar.

Have you ever had any problem overdriving the 3rd emim from the top? I understand that the RS1's are designed as a point source with several crossover points and that the 3rd emim from the top takes a large load. I would love to build some wings for my setup as I believe the imaging would be enhanced.

Where is that blue FET???? Is it hiding?

I guess the big boys are showing their cards now :)

Thanks for sharing,

Jim

Jim,

I have always wondered if the pressure waves from the woofers have much effect on the emim. I could swear that I can see movement of my emim when the mid/hi is turned off and only the woofers are running. I would really like to be able to measure this effect. As the mass of air being moved increases .. i would think the effect would also increase.

Any thoughts Jim ... Klaus??? Michael?

I do not think the RS1 and 4.5 are similar to the bass. The 8 "of RS1 and the 12" of 4.5 can not physically sound similar, because not even the mechanical size allowed. The 8 "are much lighter and therefore much faster pulses. Watkins are cumbersome to some, and therefore can not be as fast.

No, I had never problems with the third Emim. The third Emim is running from 600Hz up to 3000 Hz. There is no problem and no large load. Yes, the RS1 was build as a point source. Thats correct, the Emim column must have some wings. See also thr RS1 wings. Otherwise you get the Emims an acoustic short circuit. The sound would be very thin without wings on the Emims.

The blue FET has an separate place with the other equipment, like CD, MD, Tuner, Vinyl i.e.

Jim, Klaus, great looking speaker systems. Love those pics.

Jim, ever since I saw your avatar I was hoping you would post some picks. Have you ever thought of bracing the emim towers kind of like the Magnepan guys do? http://img135.imageshack.us/img135/5043/p1010254d.jpg
The image is off the internet just to give you an idea of what I mean. Not sure of the benifits since the emims aren't going down very lower but there is still the resistance pushing the towers back. Just a thought and in no way a critisim, i absolutly love your speakers.

Klaus, thanks for the great website. It is partly to blame for my Infinity obsession.
Jim
 
OH MY GOD.

Those are amazing looking! (both DCMaster and Dual 45)

Wow, just WoW!

I can only imagine what a line array of EMIMS (and EMITS) must sound like....

Thanks Slim and Jaz,

I have often thought of some sort of baffle/wing for the mid/hi section. Your comments are appreciated and welcomed. I also appreciate the link you provided.

Klaus, Could you please provide me more direction to the thread on RS1 wings... Maybe a direct link?. I don't seem to be able to locate it. I understand the theory of "acoustic short circuit" but had always thought that was more in lower frequency range. It likely true in the upper frequency range too. Anyway I know that there is always room for improvement and I believe that there is improvement still to be made on my setup. I surely meant no offense in comparing your setup to mine. Just that the sweet fulfilling Infinity sound may be something we both enjoy. I am sure that there are many differences also.

To all that have commented.... I appreciate your kind words and evaluation.

Thanks,

Jim
 
I'm working on my brother's Infinity 3000s. Problems are new rubber surrounds, broken grill panels (reworking them with a double layer of hardboard rather than the original particle board), and a cabinet (oiled walnut veneer particle board) bottom that stayed way too long in a pool of water (lots of woodworking there). Other than that they will need testing after all that is completed. No point in photoing them in this condition.

I know very little about them. Any comments?
