Please Post your Infinity speakers

Mark,

At various times, I have used an X-15, a 2400, and an X-25 to power them (150, 200, and 250 watts, respectively). Aside from the fact that I'm a little partial to the X-series, I really didn't notice a lot of difference between the three. This is definitely a case of diminishing returns - I doubt there is any meaningful difference between 200 and 250 watts on these.

On the other hand, Infinity recommends amps in the range from 35-250 watts for them, and I think 35 is way too low. I think anything from 125 watts on up would probably be a good choice.

The guy I bought them off of said they were real efficient and would run on a 40 watt amp. But I found out to really get into them a bigger power amp would be the ticket but wasnt certain how much power they would actually handle. Ill have to look into both SAE and Acurus, Jygesq, since you seem to be happy with them. Ive heard SAE with PA systems and they always sound impressive, real warm with a nice high end sparkle to them. But heard they were'nt good road amps,not happy getting bounced around in a truck. Cant have everything,right. Maybe ill post a pic when I find a good mate for my Infinitys. Thanks guys!

I got tiired of refoaming the poly-woofers and mids, and replacing the fuses for the EMITS, soooooooo...

~1999, scrapped all the OEM drivers and replaced them with much "beefier" 10" er's (DVC 300 watt rms attitudes) and some better midrange 4"... plus I dropped in an EAS100th Panasonic leaf tweeter (since the emits burned up)..

I also scrapped the crappy caps from Mexico and replaced the ferrite core inductors in the xover... had to reinforce the particle board joints since the new woofers blew out the seams... but it was worth all the work... they now are my 2nd system in the HT.....


My "bastard" RSII's..

yeah... it's always a travesty when one makes obvious improvements at the expense of that vintage sound .... :tears:

but time waits for no one... :yes:

it's the "curse of a diy-er..." ;)

Im curious, Auplater, how many Watts does your Wok put out? Of course that question has already arised, Right? For certain you have one of a kind RSll's. Thats surely a curiosity what they sound like.

Looks to be 1 KW...it's a sizzler for sure...:yes:

Actually, the improvements were substantial. Replacing the poly mids with Kicker resolution mids made a big improvement in clarity...then after the umteenth woofer refoam... the woofers went for other duty and the new ones were installed. <<-- much tighter bass with vastly improved power handling (better for ht) :banana:

cabinet reinforcement was a necessity b4 the driver swaps... Infinity wasn't the best at cabinet assembly... these things always resonated and buzzed, especially the solid oak wings... not sure why they didn't use more reinforcement on those... my set dates to 1979.... maybe why they went on to RS IIB's without the offset cab

Putting poly caps in the xover seemed to improve the imaging and swapping out the lousy trimmers fixed ongoing noise and intermittancy problems.

All in all, a worthwhile upgrade for sure... assuming one wants to get additional life out of the cabs and isn't looking to "investment" continuity for "original" legacy infinities.

I have kappa 7.1 serie II, excellent with solid state amplifiers but with tube amplifiers are very hard to move or to excite, best regards, Martin
 
Gotta Look To The Future

Auplater, was Les Paul from the Far East"I did not know that!" Just having fun. Anyhow I thought about my RSll's future when the supply of infinity drivers go dry. Plus could I really improve the drivers and with what? I thought about the old standard upgrade to JBL . The bottom tens, now are they identical with the bottom ten, and just filtered for very low subsonics. When I first got mine I thought it wasnt working till a program with sub organ type bass was passed thru and saw it vibrating. Then I knew it could'nt be from the top bass driver because they dont share the same enclosure they are seperate from one another. You say ,improved power handling on the mids. How much power is that? I ask that because mine were popping when I drove to much bass thru them, but was from low powered receivers mind you. Then I ran my Yamaha PA power amp thru them and everything cleaned up and handled the bass very well. I thought about changing the crossovers to the mids to a higher crossover point to filter out excessive bass till I figured out they needed a cleaner power amp. Was this your experience too before you did the change over. Anyone else experience this with the RS's? Thanx in Advance!

Modified RS II's

Problem with the midranges wasn't power handling... the rubber surrounds embrittled and split... and better cone mids also improved the clarity and imaging.

Power handling on the woofers made a big difference... I could drive them with either my nak 730 (150wpc @4 ohms) or my Adcom 555 II (~350wpc @ 4ohms) after the new drivers and they'd only complain at levels way beyond what the stock woofers would do.

Never bottomed out the mids... they just weren't as fast as the replacements... and the leaf tweeter was quite an improvement over the emits.

Rick,

what...the.....heck.....is .....that monolith in your avatar? Transmission line full range single driver homebrew?????

Someone was gonna ask so it may as well be me :D
 
Does anybody have experience with an Infinity 3000p? I just saw one at a thrift shop. The cabinets are not up to par with my infinity kappa 7. Does not look like it has emit tweeters.

thanks.
 
I have:

and
IRS0.1d.jpg


And had the Modulus too:

But switched them for the IRS1.5. On one hand I'm sorry for it, because they looked cool. But on the other hand, they sounded not like an infinity at all..

And I found these QLS for my brother:
02.jpg


But I believe the filter of the last ones needs to be redone. Because they sound terrible... Therefore I'm redoing my IRS1.5 filters at the moment :)

Bunny,

Regarding the QLS. Is that the only placement they have been in? They look too close to the back wall and too close together for good sound. Just basing this on my Q2's, which like to be much farther away from the walls. Something to try if it hasn't already been done.

Man, those QLS's look like a real macho speaker don't they? Big utilitarian looking brutes. I'm still looking :yes:
 
That is the only position, because that is the only place they can be seated. More in front, then you can't enter the room no more. More appart, then you can't open the door no more.

And they are pretty good, no boomy or something. Suprisingly, my IRS1.5 are way more critical for that mather.

They only miss in the midhigh, for what I suspect the domes. But well, they look nice idd :) Definitly in a big room I can imagine, but I don't like their sound at the moment...

Hi Bunny,

I wish i had a brother like you. :D

What are those thingies between the Glorious pair of QLS? Also, that's a nice Rack for the thingies.
