As per my post on the old SE34I.2 forums (
https://www.decware.com/cgi-bin/yabb22/YaBB.pl?num=1438854481/0#0), I have been using my SE34I.2+ in my bedroom for late night listening. Driving Rega RS-1 speakers at 89-90db @1w1m, this can get quite loud and even keeping the volume at around 9 o'clock sometimes forces me to cut the volume further down at the source (streaming music from iTunes from my main system or TIDAL) which I do not prefer.
I am planning to buy a set of Graham Audio's 83dB / 15-ohm LS3/5 speakers. The LS3/5 is one of BBC's monitors which is re-produced by few companies under license and Graham is one of them, maybe the best.
So now, my question is whether my SE34I.2+ would push all frequencies evenly to such low-efficiency speakers across the audible range. Most probably, no one has experience with this; I know. But is the reaction of a two-way 89dB speaker similar to a two-way 83dB speaker with the exception that the latter would require 4 times more watts to reach the same SPL?
I know this sounds like a weird question, but any comments, suggestions, or brainstorming would be appreciated.
Best,
Alper
