Thankyou for offering information! For about 15 years I have been listening on low-efficiency speakers...mostly my own DIY (built by myself) LS3/5a from Falcon Acoustics in England. I also have one pair of NHT 1.5 speakers, and I alternate between both, with one Sunfire subwoofer used sometimes.
My room setup is TOTALLY CONTRARY to most audiophile rooms. Truly. I listen from the VERY NEAR FIELD...which is something that needs explanation.
My listening chair is LESS than one meter from the loudspeakers, and the speakers are about one meter from each other. That is, the two speakers and myself form an almost equilateral triangle of one meter each way! Goodness! That is truly contrary to most rooms!
But the imaging is superlative, and the expansiveness of the stage seemingly endless! It is truly trompe l'oeil to the nth!
Because I am so close to the speakers, my system does not need much power. Modest wattage gives satisfying sonic levels at my listening spot...so, I can get away with driving my DIY LS3/5a with my little 17.5 wpc!
Obviously, large speakers cannot be used in this configuration, because the sound will MOST probably NOT be integrated among the drivers, because the drivers will be too far from one another in a big baffle. But the LS3/5a have the drivers very close together, very well integrated to listen from up-close.
Listening from the FAR FIELD, is the way to listen to large speakers, such as horn designs. This is a totally different experience, where imaging is a different experience...and not as dramatic as the near field...it is more homogeneous.
Anyway, my budget right now does not permit purchasing speakers. But it is interesting to know the information, so as to begin building a dream system...Thanks for offering your expertise. Try listening from the very near field, and see what your impressions are!?
