Speaker & Amp Impedance power

[dalegribble]

I have this Dali Concept 10 that been stored and was going to buy Vincent SV-236 MKII Integrated Amplifier worth under $2500 but i may have trouble with the spec

System/Format: Hybrid Integrated Amplifier, with remote control.
Frequency response: 20 Hz - 50 kHz +/- 0.5 dB
20 Hz - 50 kHz +/- 2.0 dB
• Power RMS/8 Ohm: 2x 150W, Power RMS/4 Ohm: 2x 250W
• Class A/8 Ohm: 2 x 10W, T. H. D.: < 0.1 % (1 kHz, 1 Watt)
• Input sensivity: 200mV, Signal-Noise ratio: > 90 dB
• Input Impedance: 47 kOhm, Inputs: 6 x RCA
• Outputs: 2 x 4 Speaker Terminal, 1 x RCA Rec Out, 1 x RCA Pre Out
• Power Control: 12V Triggerout, Mains supply: 230 V/50 Hz
• Colour: black/silver, Weight: 18 kg
• Dim. (WxHxD): 430x150 x435 mm, Tubes: 1x12AX7, 2x12AX7

The Dali Concept 10

Frequency range (+/- 3dB) [Hz]: 35 – 25.000
Sensitivity (2,83 V/1 m) [dB]: 91,0
Nominal impedance [ohms]: 6
Maximum SPL [dB]: 114
Recommended amplifier power [W]: 50 – 200
Crossover frequencies: 600/3.200

What worry me is the Nominal impedance the speaker has 6 to the Amp 8 and most Amps and receiver are 8. The other thing is the power says 2 x 150 W meaning 300 W i presume. The speaker says 50-200 but doesn't indicate if it for each speaker if it goes to 200 on each or both making 400 W. I am worried would it blow the Amp or speaker and if it ok what level can it be pushed. I rarely had my old stereo up to volume 3 and that was loud.

6ohms will typically not be an issue for most amps, certainly not that amp. Since it clearly lists 4 Ohm capability, I wouldn't worry about it at all. The speaker's wattage rating is MAXIMUM, not REQUIRED. Speakers don't have watts.

I see no problems at all. I use a Vincent SP331MkII and it can drive 4ohms all day long. I drive my Kef 104/2's with it and they are a nominal impedance of 4 ohms/, Amplifier Requirements: 25-200 watts per channel into 4 ohms.

Cool thought I wasted money on Large Speakers with power but more for Theater .
