A question for you all a chap who owns a pair of LEED speakers,
Impédance nominale : 4 ohms
Impédance minimale : 3,5 ohms à 300 Hz
Puissance admissible : 500 watts
Régularité bande passante : +/-1,5 dB de 100 Hz à 20 kHz
Réponse en basses fréquences (Bessel 2e ordre): – 3 dB à 50 Hz /- 6 dB à 25 Hz /- 8 dB à 20 Hz
Réponse en phase : +/- 15° de 500 Hz à 20 kHz
Directivité de 500 Hz à 20 kHz : – 3 dB à 30° / – 6 dB à 45°
Sensibilité : 83 dB / 1 m / 2,83 v
Poids : 15 kg
Dimensions L x H x P (au sol) : 39cm x 108cm x 41 cm

Is driving them with a,
Resolution Audio C50 Integrated Amplifier (From C50 owners manual).

Dimensions: 43 x 22 x 5 cm (net) / 54 x 33 x 22 cm (shipping)
Weight: 5.5 kg (net) / 12 kg (shipping)
Power Requirements: Preconfigured at factory
100-120 / 200-240 VAC, 50-60 Hz
Power Consumption: 160 Watts maximum active mode, < 1 Watt standby mode
Inputs:
Balanced: 2 pairs, XLR
Single-Ended: 2 pairs, RCA
Outputs:
Speaker: 1 pair, 4mm bananna
Red – positive (+)
Blue – negative (–)
Yellow – ground (if available on loudspeaker)
Power Output: 50 Watts into 8 Ohms
Maximum Gain: +26.5 dB at volume level 100
Analog Attenuation:
0.5 dB steps from -30 dB to maximum
1.0 dB steps from -70 dB to -31 dB

I am going to look for some measurements of the loudspeakers but LEEd are not common, I actually heard them being demonstrated at the Munich show fifteen or so years ago, they are worth a look if you are not familiar with them.
Question is would you say the Leeds are being properly driven by the Resolution integrated?
Thank you in advance,
Keith

There is no web information about the Leed H E2 Loudspeakers. I attempted finding details and stuff but to no avail. If the amp's output wattage is linear'ish then the 50w/ch will seem like more. Otherwise it might be a bit low going off of the speaker efficiency, my gut feeling and previous experience with amps and speakers.
Re: Sensibilité : 83 dB / 1 m / 2,83 v
It's a unique amp for sure. I've never seen a ground terminal for speakers before this. I almost thought it was bi-amp'able with the blue color of the speaker negative terminal.
