Hi everyone,
I have an Audiophonics stereo Hypex Ncore NC122MP amp feeding a pair of ELAC Uni-Fi UF52. I am getting itchy about upgrading to a more powerful Hypex-based amplifier and I wonder whether there would be an obvious advantage on having the extra punch (apart from the possibility to upgrade to harder to driver speakers).
The speakers have a sensitivity of 85 dB at 2.83 v/1m and a nominal impedance of 6 Ohms. According to
this article, the minimal impedance is 5.2 Ohms between 200-600 Hz.
Cheers,
Emilio.
I'm a little late to this thread. Anyway, upgrading the amplifier, without other significant modifications, probably is not going to give your speakers extra punch.
I have a pair of Elac Uni-Fi Reference UBR62 speakers, which also suffered from a lack of punch, even with nearly 400W/channel on tap. Even with a subwoofer covering the bottom end they lacked dynamics.
I took out the crossovers and inspected them. The inductors in series with my woofers have a combined DC resistance of 1.6 ohms. That results in a low damping factor, and thus a lack of dynamics in the bass. Could your speakers have the same issue? Perhaps, but I don't know.
I ended up leaving out the passive crossovers and going all active. This made a significant difference and now the speakers now have much tighter bass, e.g., more punchy. Actually, they just are much better overall, night and day difference, at least to my ear.
Not that I recommend modifying your speakers, but if you're curious why I did not just get better speakers, read the last paragraph of the first post here:
