Please Post your Infinity speakers

Newbie here, first post and all.

I've been an Infinity-phile since the 80's. I purchased a set of RS-4Bs in 1988. . . . I came across a one-owner pair of RS-IIIB's at a very attractive price . . .

Ok, you know . . .

:worthless
 
I have a pair of Renaissance 80

Kappa 5, RS 2000, RS 4000

Modulus (90's version)

They all bought from second hand shop
 
Pacolam - Wow, what a great collection!

You've got a pair of the 1990 Modulus, which were B rated in Stereophile. I'm interested to know what you think of them compared to the other larger Infinities?

Oh, and welcome to AK!!
 
Got a pair of Primus 360's today to go with the RS-IIIb's.

Pacolam, that is one fine collection. I really like the looks of the Renaissance 80's and the Modulus speakers.

Hi Tedrick. Nice to hear your 360's arrived safely.

Care to post any early impressions? :D
 
Monitor II towers and newly acquired Kappa 7s

I've owned a pair of monitor II towers for well over 20 years.

Just picked up a pair of Kappa 7s off of the local Craigslist. Not that I need more speakers but couldn't walk away from $50 for the pair. They'll need refoaming and one of them has a stained top but otherwise immaculate.

Hello Negotiableterms,

I'm a beginner of here, it was the first time I post my pictures here.

There are some difference of Modulus (90 ver) compare to the other Infinities, because of the "time tech." I mean the mid/woofer a little bit behind the emit.

It makes the emit perfect match to the little mid/woofer, two drivers are in the same time same phase to my ears, so the sound is very smooth.

Not enough bass because it designed to use with subwoofer. I try to use RS 4000's 8" woofer be a pair of sub woofers, with active crossover, the sound is much better than only a pair of little Modulus. But they're not perfectly match, I think the original Modulus sub woofer will mix better.

Long time ago about 199x, I owned a pair of reference 50, 3 ways, the tweeter is emit-r, is good in that price, compare to the Modulus, the Modulus's mid and high are better and smooth, human vocal is better also.

RS 4000, the woofer is good, the emit is excellence, but the midrange unit sounds not match each other, finally I found a reason why. The sound and the phase (+ -)of mid driver unit, is opposite to the emit and woofer, I try to change (- +) and reconnect it, is much better then before. But Modulus still better because of the difference quality.

I check the inside connection of RS 4000, the wire connection colour is right, nothing wrong but the midrange comes out opposite phase sound in right connection, I don't know why?

I found some strange things of some Infinity models too, the phase are not all correct in each driver units, even I check the inside connection, it seems right, the sound of all driver unit come out are not in the same phase together, so I need to check and reconnect the oppsite(wrong) one.

I have 3 pairs of Infiniies that the phase have no problem:
1) RS 2000
2) Modulus 90 version
3) Ref 50 (sold out already)

And I have 3 pairs of the other models that I owned, I need to do the reconnection for them.

Are you sure you don't run a shop?

I was crazy before, bought so many speakers in home, I think I will not be the same after this time. Because I found my Ren 80 is my cup of tea.
 
Pacolam, welcome to AudioKarma! Like the others have hinted at, your collection makes us jealous while making you fit right in.

Aha! So I'm not alone in this, though I never thought that I'm the only one who can hear incorrect phase between drivers. The midbass drivers on my Quantum 2s are supposed to be connected out of phase according to the crossover schematics, but the sound in this frequency region is very off compared to my other very good speakers (Tannoys, Magnepans, etc). When I connected the midbass driver to the correct phase both according to the wires and to observed cone motion, the sound is much improved. Yet, others were not at all hesitant to proclaim my change to be incorrect. :dunno: Interestingly, my Q2s are a very early pair (one off from those pictured in the brochure) and were connected opposite to the schematic, only the later variations were connected out of phase as I discovered in my mirror-imaging project.

I say, connect the drivers how they sound best, though preferably so everything is properly in phase. Manufacturers are not immune from messing up their wiring (Bozak was notorious for mislabeling the midranges in their 302As making for most units being connected out of phase), so if they sound better to you connected in opposition to the schematic, then so be it. Frankly, I believe the schematics and subsequent wiring to be a marketing gimmick -- makes them sound more exciting in the short term and makes for artificial imaging, such as with the Wilson WATT/Puppy 7 -- and have no quarrels with making the change.

I like the looks of RS IIIb's too, the colourless woofer can see inside and the wood is still very trendy even today. Also they have the Infinity's outstanding drivers - emit tweeters.

Happy listening!

Agree!
I'm sure that we found the true reason.
 
I just brought home a pair of Infinity RS 2.5,s but it may be a while till they get into use due to amp search is on going!! :yes:

Hopefully, someone here can tell you just how low the RS 2.5s really go in the bass range. 2 ohms would not surprise me, so you need a very robust amp!
 
Three of a kind

A pair of Qb, Kappa 8.2i and (Genesis) model II.
Viva Arnie Nudell!

I read in a German review that the RS-IIB's are 1.4 Ohm at 40Hz. Maybe they are similar.

Right on Razor,
The RS 2.5's, RS 4.5's, RS1B and RSIIA-B all use essentially the same drivers and the impedance is very, very close to being the same under load.
