Note that 250W is 23.9dBw which means that it will drive an 85dB speaker to 108dB with 111dB peaks, theoretically. In a large room with the volume control 10dB below max we’re measuring about 25W of continuous power. This is loud! Most power concerns are more about control rather than how much real power is delivered. This gives further advantage to Class D and switching power supplies as their efficiency is high even at lower power outputs helping them sound ‘bigger’.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"white\u0026gt;\u0026lt;span style=\"\u003e\u003cspan style=\"font-family: helvetica, arial, sans-serif; font-size: 12pt;\"\u003e\u003cb\u003eWBT NextGen Speaker Connectors\u003cbr\u003e\u003c\/b\u003eThe WBT NextGen connectors provide the best possible connection from the amplifier to the speaker cables.
