As some of you already know we have been working on an Active version of the LFR1100. The advantage to the active version is twofold. Since we have a DSP for each speaker controlling the five groups of drivers (Front Low, Front Mid, Front High, Rear Low, and Rear High) we are able to create a more refined family of curves in the "Spinorama" to achieve a new level of accuracy. There is also the advantage of being able to achieve a higher maximum dynamic power reproduction by eliminating the internal crossovers and being able to dedicate an amp channel to each of the five driver groups. It is very exciting to see it finally coming to fruition.

Wow ... once you have experienced a dedicated amp for each set of drivers with no crossover, regular speakers just won't "do."

The problem is we love our 1100's. Ian, you are a troublemaker.

Oh please Mr. Chase. Describe for me what I will experience.

I've written out the Laplace transforms for active and passive speakers on the napkins in front of me and clearly see how poles and zeros will shift on the root locus. For the life of me though, I can't resolve the synaptic response eigenvalues to determine my emotional response.

So please tell me. Will I experience a rhapsodic rapture?

Can't wait, Ian. This will be a fun road to go down.

I see the LFR1100 has gained a rear sphincter.

And it will reach 124dB in room at steady state and up to 129dB peak! I think at 130dB, the covariant quantum fields that comprise our universe start to break down. LOL!

According to the product page, these will offer pin-point imaging while expanding the soundstage.

With my non-LFR v4, I swear one can be fooled into believing I have surround on most songs when in 2.0 or 2.1. I haven't tried with movies.

With the LFR Actives, do I need the 160 and QS10? Do I really need an 800?
