Considering a POSSIBLE replacement for speakers. Opinions?

@mijostyn: Ah yes, but there is a cure for the one weakness in the ET LFT-8b (ignoring in this discussion it's inefficiency, which is actually not as severe as are Maggies. I have both.)---the matter of mating the planar m/t drivers with a monopole bass driver (woofer in a sealed enclosure), good as the LFT-8b woofer is (much better imo than in any other hybrid.): use the GR Research/Rythmik OB/Dipole Sub in place of the ET woofer (which has it's own binding post on the top of the woofer enclosure---to facilitate bi-amping or bi-wiring, and may be left unconnected).

The OB sub is, like any and all planar loudspeakers, a dipole radiator, with a figure-of-8 radiation pattern, a null to either side of the OB frame into which the dual-12" woofers are installed. It shares that pattern with the LFT-8b planar drivers, eliminating the problem of the spl-drop off with distance differential found in "normal" hybrids. Clever, ay? ;-)

The GR Research/Rythmik OB/Dipole Sub can be used up to 300Hz, safely above the 180Hz planar/dynamic-to-woofer x/o frequency of the LFT-8b. A single sub (containing a pair of 12" woofers) may be employed on each channel (left and right, in stereo), or multiples may be stacked up on each side. Choose the number of OB Subs based on the desired maximum-spl (and available funds ;-) .    

Hello bdp24,

     I've never experimented with an OB sub, or even heard one in action.  But I'm still theorizing that 2-3 OB subs, independently and strategically positioned in the room either using measurement gear, room correction hardware/software or just subjectively by ear, would likely yield the best results.

There are so MANY great speakers available. As Jay says there is no perfect speaker.
I dare say whatever speaker you buy will fill your needs. Provided they match up even half assed with what feeds them.
In my case I made a road trip (7hrs) to hear the speakers I bought. And heard them through equipment, and room, that unless I hit the lottery would never own. But know the potential of what I bought.

Make sure you also hear the best selling high end speaker of all time.The 3.2 k newest Vandersteen 2Sig 3 Its offers amazing potential in that it works great with your B&K and well beyond will give you a more sophisticated level of performance then typical box designs.Achieve the proper tone with voices guitars and timing of the recording venue that are MIA in conventional Box/ steep crossover designs.
