Matching Head and Cab Wattage

[m2466d]

Any opinions would be greatly appreciated. I bought an Eden WT-550 head-550 watts at 4 ohms-and I own a Dr. Bass 2X12 1000watt 4 ohm cab. I've heard different things about how head and cab wattage should match up. Any opinions on whether this is a good match? Thanks!

Watt ratings are largely inmaterial. What counts is displacement limitation. If those drivers exceed xmax at 250 watts, it ain't working... The only way to know for sure is to find out what driver your cab is loaded with, get the parameters, measure the box/ports and reverse engineer it on WinIsd. Make sure xmax is in your driver data, put the signal to 500W or so and look up the excursion graph.. If the response line crosses the red one in the 50-100 Hz range.. as they say on "Lost In Space".. danger will robinson...

Thanks,Seamonkey. Dhomer, can I take a class with you? That's a ton of knowledge inside one brain. Thanks, TB's the best site on the web.

Watts mean nothing. Play through your rig. If it sounds good it is good. If it won't go loud enough you need to double your cab count, preferably with an identical cab. That would be the difficult part in this particular case.

Haha!

Just be careful to listen for the dangerous warning sounds of underpowering that cab. With only 550 watts going into a 1000 watt cabinet it could split your speaker cones or blow the voice coils right through the grill. I read it on Talkbass.
