Should I modify my SR4732A'a or leave them stock?

[QUOTE="Silas Pradetto, post: 24704, member: 34"] Re: Should I modify my SR4732A'a or leave them stock? Looks like the impedance minimum on the horn in the spec sheet is around 14 ohms, but I can barely tell because it's such bad quality. So to get 150 watts at 14 ohms you need 46 volts. That equates to an amplifier rated for 262.5 watts at 8 ohms. Of course, HF drivers don't mind lots of transient power, right? There's nothing saying that the 2447J wouldn't like 6dB of power above the rated 150 watts, meaning it might even take 600 watts for a split second. Going that route requires careful limiting though, which the XTi can't provide. Am I correct in these statements, Bennett? [/QUOTE]
