What's with 4 ohm speakers?

Tell you what I'm going to do. Got another couple projects coming up this summer. I'll make up a 'quick and dirty' mono cabinet with 4 small, induvidually sealed midwoofers. Each will have it's own terminals that I'll hook up individual, parallel pair, series pair and series/parallel, measuring amperage, voltage and frequency response. Don't have state-of-the-art testing gear but should be consistent. No crossovers. Bottom woofer will be at least 1.5 feet above floor. Planned drivers are Dayton DS135-8's, which are fairly conventional except for small size and required cabinet volume.

Since the question was never about percieved sound quality or matching amps, (tube or SS) I'll just use what I have.

Never actually seen this done before, just math and theory.

For modern amps 4 ohms is a doodle. Its not an issue.

Thanks

Excellent post.

Ngjockey, Pipedreams has done something like that. I've seen Pipedreams that were 4 ohms, and the exact same model in 16 ohms.

Seems to me the ZU Definition, normally a 6 ohm speaker, is also available as a 30 ohm speaker.

Drew + Duke + Ralph = lots of good info.

The thing with voltage paradigm is, it represents the vast majority of products out there today whereas power is perhaps having a renaissance in high end circles but remains distinctively as more of a niche approach these days, for better or for worse.

You need to be well advised or know what you are doing to get the best results out of either. Lots of ways to hit or miss either way. Excellent results can be achieved either way, as long as all the parts fit together well. Each has its unique ups and downs. Having a choice is a good thing. I hope it stays that way!
