So if the rear of the LFRs are running around 10 ohms and the front around 4 ohms you would need 2.5 times the power to the front (10/4). An ADA1000 for the rear at 250 watts and an ADA1500 for the front at 650 watts works out pretty well.
So this is where we get into the dumb questions - if the rear is running 8-10 ohms then doesn't that reduce the power available from an ADA-1000 to 125W from 250W (presumably a function of rail voltage) ?

This is the confusing part, but try to think of the power in terms of SPL instead of watts. The watts are just a number to achieve the desired SPL.

So i got this email the other day about this rather incredible deal. It really has me thinking. I've been contemplating a change out of the M60s for some time for numerous reasons. I thought about getting some Monitor Audio speakers (now making many more 3-way designs) and keeping the M60s for the kids into the future. But, a 100% trade in value?
This is seriously tempting.
Ian, expect to see a PM in your inbox. I have questions.

Hi Can I assume that I will not get full price for my M80v3's if I trade up to LFR880's if purchased through B-Stock or as refurbished?

Cheese. I went from m60's to LFR's. At the time i was considering a pair of pre-owned wilsons... I'm glad i went with the LFR's.
Ian, what if one wanted updated cabinets.. But wanted to maintain their serial number and signatures....
Would that be worth while? I know there have been some updates to the cabinet design..

We need to get someone to take away Ian's pair of 1500-2's, replace them with a single 1500-4, and see what happens That sounds like me! Except I bought my own stuff and Ian still has his...

Hi Dakkon,
It may be worth considering a trade-in for the v4 LFR1100s as you would get the new tweeters, woofers, crossovers, and code too. We can figure out a good deal for you on that and keep your special rear labels.

Would that be worth while? I know there have been some updates to the cabinet design.. I updated mine but had to send back my original set and get new ones. I never asked but I'm sure that signatures could be redone on your new set. This upgrade is very worthwhile! I see Ian just posted that you could just get your labels moved.

For those of you with LFRs, I am curious about a couple of things.
Do any of you have them set up assymetrically in a room? By that I mean do you have one closer to a sidewall than the other? I am curious what such placement would have on soundstage and imaging performance.
My other question has to do with imaging precision. I am not new to omni-directional speakers. I owned 601s and have listened to 901s and Mirages. Also KEFs that advertise the large sweet spot. I am far more impressed with the holography of the soundstage from my M5s and M100s than any of the above (there's just no comparison). Now I know the LFRs are far more refined than all the above but I can't help but be skeptical about imaging precision. I was listening to Jacques Loussier on M5s last night and I swear the percussion was 3 feet outside my livingroom window and the piano was well inside and 6 feet away from my left M5. Can I get that kind of performance from LFRs?
