In Reply to: RE: How will efficient speakers/amp on batteries compare? posted by Coner on March 17, 2012 at 21:57:51
So this isn't usually done? There aren't many people using strictly battery-powered components and super-efficient speakers? What are the drawbacks?

I am using custom tripaths on my horns the price of energy is my motivation. I plan to use them more and more from the bass up. A battery tripath on horns is a awesome thing if done right. All these guys are biased to wards tubes. Half here prolly haven't even heard a tripath horn set up. imagine having worked on designing and building the best tube amps you can build for ten years like I have or double that in case of a lot of guys here only to find a sla tripath outperforms there tube amps? I wouldn't want to even know.Get it? Tripaths love horns they are not strong on anything much less or the smallest tripath chip I am referring too. I have not tried any bigger. Mine runns on a single large sla for 2 weeks before charging. You can get good sla's from ex government ups supplies often sold at auctions for scrap weight or less. I am considering building a sla powered dht preamp atm. Battery's rule. If your loaded try Jeff Roland amps.
That sounds awesome. I want in!
It's funny, with my old system I first picked the speakers (Magnepan MMG) and built everything around that until I realized that since they're so inefficient and require a beefy power amp, I can't do any real isolation from the mains. In my experience, the power source is ultra-critical and a noisy one will render everything else crap. I've tried every type of power conditioning except batteries and a regenerator, and neither of those are possible with an amp that can do the MMG's justice. That was my first real attempt at building a good system. This time I'm starting from the power source and building everything around that. Experience rules. :)
Specifically what would you suggest for battery-powered amp and horn speakers to start out? Say, less than $3K?
I built 2 gain clones either I wasn't good enough or they where not good enough. My little Chinese custom tripath amps beat them real easy. As did any of my tube amps. I found the gain clones where happier with SS speakers. IE current drive speakers as apposed to the tripaths that die quick when asked for current mine are similar to a strong 300b in power and drive. They love hi impedance hi efficiency loads. I want to try kit hiraraga class A amps someday.
.
Any amp that can drive the MMG's with enough power can't be put onto batteries and it's debatable whether or not a regenerator would be up to the task. A regenerator doesn't provide the real isolation from mains that batteries do though.
I'm talking isolation tranny, why not use that?. I have a 20A
unit, so that should be way more than enough.
I've tried Tripp Lite and BPT personally.
Hmmm, I don't see how noise can make it through the tranny,
since it's tunes to 50/60 Hz. Maybe an engineer can tell us.
I wouldn't think many are, if I was off the grid, I might
go that route, but otherwise a big NO. I have had no
problems with the grid AC here. But I admit, I'm on a dead-end
country road, with my own transformer on the utitlity pole. Nice!.So, I don't know what all the fuss is over AC noise, I've
never experienced it. I would think it could be filtered out
without alot of expense.
