Aloha,

Here are the specs on my YBA amp:

50Wpc into 8 ohms (17dBW), 90Wpc into 4 ohms (16.5dBW). Frequency response: 10Hz–40kHz, ±3dB. Total Harmonic Distortion: 20Hz–20kHz, ±0.02%. S/N ratio: !w95dB (A-weighted). Power consumption: 260W (full power).

I'm curious to in home demo both the Monitor Audio Bronze 6, and Silver 6. The issue is that the minimum recommended amp power for both speakers is 60w, and my amp is only 50w - albeit a generous 50w.

I realize pushing the power envelope would be very equipment specific. Having never done it, I'd like some general feedback on the prospect.

My current alternative is the PSB X2T's which only require 20w. But they cost twice as much as the Monitor Audio Bronze 6, are huge in comparison. I've ruled out the PSB X1T's due to mediocre reviews.

All feedback is welcomed!

I think the 4 ohm power rating is more relevant, and quite adequate. The speakers in question have their lowest impedance, which is closer to 4 ohms than 8 ohms, at the lower frequencies (40 to 400 Hz) where higher power is needed. The "nominal" impedance of 8 ohms is somewhat misleading.

The sensitivity spec on those speakers is also 90 db/watt, which means they really don't need all that much power. That means that 10 watts will produce a 100 dbA sound level, which is a VERY loud output, and 20 watts will produce 103 dbA, and 40 watts will produce 106 dbA, etc. etc.

The bottom line is that your amplifier is definitely powerful enough for those speakers.

You said previously that the PSB Imagine X2T were "huge by comparison" to the Bronze 6.

I see that the X2T are 9 inches wide, and the Bronze 6 are 8 inches wide.

Also the X2T are 40" tall and the Bronze 6 are 38" tall.

Those seem like pretty similar dimensions.

It does not seem that one is huge compared to the other.
