Epid Midi 125 System Reviewed by Mark Fleischmann.

I noticed something strange in the review though. Why are the SPL levels so out of what the specs on the site are? The QS4s were measured at almost 10db lower!! The rest were 5 or 6 db lower. What?! sick They all measured much lower sensitivity than claimed. The EP125 measurements were also interesting...... shocked -3db point measured at 46hz.

I don't think Axiom should specify a different sensitivity for in room vs Anechoic. The anechoic values weren't even met.

For home theater mag this package is definitely in the value category, which I think is why it earned a best buy award. Glad to see axiom is getting more exposure to the american market. I wonder why they didn't send out a flagship package?

Good review to check out.



Hi Hellcommute,

I had a close look at our specifications and the results that Home Theater Magazine obtained and I'm not sure where you are seeing that we are 5-6dB lower than published.
We rate the M2V3 at 86dB anechoic and HT measured 85dB. Note that we tend to average across a larger band (300Hz-3kHz) than HT does (500Hz-2kHz), so this could account for the difference. Then again, a 1dB margin of error is not bad considering they are making a quasi-anechoic measurement and we measure in a chamber.
The VP100v3 is rated at 90dB and HT measured 88dB. Again, I think this is pretty close given the possible margin of error and averaging bandwidth.
The QS4v3 deserves some explanation. Because of its quadripolar radiation pattern, a simple on-axis measurement to determine the system sensitivity does not account for the entire radiated output of the speaker. Our specification takes into account the hemispherical radiation pattern. The 3-face measurement method that HT used also explains the bumpy nature of the system response. Our anechoic hemispherical average is much smoother and more closely reflects the balance you will hear in a room. In all cases our Room Sensitivity measurements are 3-4dB higher than the anechoic measurements because of the contribution of the room reflections and room gain to the perceived sensitivity of the speaker.

I hope that clears up why some of the numbers don't align perfectly with our published specifications.
