Are Lowthers a "full range listening" speaker?

To TWL: (or anyone else)- I am intrigued by the concept of back-loaded corner horns because when I used to own a pair of Quad 57's all I could think was that the sound was basically perfect if only they would go much louder, deeper, and a bit higher! My very broad tastes includes a lot of music which is delivered in concert through electric amplification, not merely just rock, but also Loreena McKennett, and even performers at folk festivals, world beat, etc. Live performance in this case is not the same as the symphony at all, from what my ears tell me in 8th row center, or the middle of the field!. I couldn't say which music I am more prepared to lean away from if I have to, but a former pair of Klipch Cornwalls, while fun at times, were way too forward and overbearing most of the time. It would be nice to be happy with both electric and acoustic presentations.

So I am wondering (after all the above) if from your own experiences you regard the Lowther type as the ticket for broad listening, since its unlikely anytime soon that I will hear them. (I know, I know---no one can answer except to their own tastes).

After following TWL's postings and others on the subject of full range reproduction, I am curious about a few things:

Have you heard the AER and the very expensive Reps and do you find huge sonic differences? Which AER? Are you thinking of parting with an extra grand (or more) for the upper end drivers anytime soon?

Also-TWL- have you heard the Oris horns and what do you think compared to your own rig? I note that Bert Doppenberg, in a discussion posting, said he no longer finds back horn set-ups the best, due to unacceptable frequency colourations and lack of low bass (though he once loved them) and even less so with Lowther drive units, which he says are inferior to his own version of AER. BD seems to be suggesting that Oris horns and full range drivers coupled to separate bass enclosures is the way to progress from back loaded horns, though at a significant cost, to be sure.

A more affordable project to me would be along the lines of the AER?/Hedlunds. Do Lowther/Voight Pipes sound similar?

Thanks!
