Bought these speakers sound unheard. Best stupid decision I ever made in my life.
When I did the RABOS, I just concentrated on knocking down the one big bass peak
in my room. No matter where I moved the Bass Tester, that one big peak was pretty much evident.
I just ignored the other small deviations from flat response, because their measurements were dependent on where I placed the measurement device.
Once I flattened that one big ass peak, it allowed me to really crank up the IL 60's Woofer level ! The IL 60 has awesome low bass capability! And once the big room peak has been dealt with, no more Boom. But, even more important, I find the IL 60 "needs it's woofer" to help fill out the midrange!
The RABOS reduction of the big room peak, allows me to increase the woofer level on the IL 60 w/o fear of boomy bass, so the speaker has the "warmth" the Infinity Engineers intended it to have.
Suffice it to say, the IL 60 needs, and depends on it's woofer level, since it does play up to 125 hz!
Every IL 60 I have seen for sale used, the owners never bothered to USE the RABOS. I was one of those Idiots, with my very first pair of IL 60's!
Then, I bought a used pair of IL 60's, and called out to Infinity, to tell them how much I liked them, and how much "better" then the IL 60's I Thought they were.
The first question Sean Olive of Infinity asked me was "Chris, did you RABOS them" ?
Then, after nicely telling me what I did wrong, he told me all about how the properly set up "lowly IL 60's" beat the **** out of the "mighty" Prelude MTS, in controlled, double blind listening tests.
I could not sleep, nor could I eat, until I finally found a another pair of the Infinity IL 60's. I had to drive clear down to Miami from here in Tampa to get them.
I still have them, all set up properly, fully RABOSED, and with the IL 36 center channel speaker. That is an awesome center as well!
I paid 600,00 used for the Infinity IL 60's and the IL 36, plus a drive to Miami from Tampa.
Let's say I have 700.00 in them, including Gas ?
I do not know WHAT I could possibly buy, for 700.00, that will beat them, or even come close. My Son, who is 32, listens to Rap, and says they really "Hit".
The Movie "The Chronicles Of Riddick" has some really scary dynamic deep bass. I have literally had my little nephews and niece nearly pee their pants watching it on the IL 60's, and this is in a large 20 by 24 ft room.
I also have owned the big JBL S 412P, and some Polk RTI powered towers, don't remember the model number. I found them to be pretenders, compared to the IL 60.
I also took home some absolutely huge Definitive BP 2000 Bipolar speakers on trial. They did have awesome bass, easily equal to the IL 60, but they were bipolar, and had too much "room sound" for my tastes.
