McIntosh XR5 mid speakers

[rex_noctu]

Hi Guys,

I was doing a renovation of XR 5 as they were in rather bad shape, finally I've hooked them up and got a question.

Everything works fine but I don't hear the mid bass speakers (036-031), I've tested them with a battery and they work, also tested them when removed the crossover and connected the battery also they move. As for the speakers, when I touch them when playing music/test tones they seem to vibrate but very little. Is this normal?

The crossovers were tested by a technician and he told me that they work flawlessly. Today I've hoked them without the MQ, but tomorrow I can connect that to my MA 6100.

Any ideas or the 8" mid just works that way?

my second question would be, what frequency they operate, to set this range on the tone generator.

XR 5 midrange operate from 250 Hz to 1.4 Khz. Very important frequencies Middle C or C4 to F6. Take the speaker and connect it directly to the the amp and see if you have sound with less than 1 watt input. Appox 1 to 3 volts.

One thing I've learned from owning a bunch of XR 5's is that they need lots of power. Your 6100 isn't gonna cut it. You'll need at least 200 wpc.
