Can you add the Monitor Audio Gold series, specifically the 300 towers? I'm curious how those stack up.
I'd talk about them and list them not just if they're efficient but also high SPL. I guess I should have an OR in the thread instead of an AND.
Like, Dynaudios that aren't terribly efficient but can take gobs of power.
The Monitor Audio Gold 300 towers say they're 90dB sensitive but don't qualify that as full space, half-space, in-room.
They say they recommend 100-200w amp. We don't know if 200w is where distortion starts to get objectionable (where the drivers get non-linear, there are breakup modes, etc.), or it's where the speaker starts to break, and on 200w peaks, or do they mean 200w of long-term 3dB crest sine wave?
Since I'm really advocating for reference-capable speakers to be able to hit 105dB peaks at half
their max power handling so at least there's a chance distortion might be lessened, it's debatable whether this speaker makes that "grade" such that it is.
It's disappointing that reviews don't show distortion components at increasing levels. Stereophile does 90dB at 6 feet, I think, but I wish they also did 100dB and 110dB!
It'd also be useful to find a review that shows impedance curve, because many supposedly "8 ohm compatible" speakers really have dips to 2.5 or 4 ohms in mid-bass frequency region (so should've been marked as a 4 ohm or 5 ohm speaker), and thus demand way more power than you're led to believe.
So when a speaker doesn't give an impedance curve, qualify what the sensitivity and power handling mean, and it's already on the fence spec-wise, I'd say it's not reference-capable.
