THANKS to all for the feedback. Very helpful and saved valuable time.
Appears the 4ohm 86db 1.7s might be a bit much to handle for my buddy’s smaller EL34 tube amp, in a tad larger open room setting. While he does not crank it up much, he and his wife also do a lot of "walk around" listening adjacent in the kitchen just behind the great room area, not always seated directly in front of the speakers. He tried some lower cost horn speakers for 30 days and was not thrilled having to consider upgrading brand new speakers, so he sent them back.
To get by for a few months while looking, he’s now experimenting with updating and modding some older Vienna Acoustics Mozart 2.5 speakers he received from a family member for free, for now. Will keep looking. Thanks!
