Fullrange with chipamp?

MagnumOpus · 28th March 2011, 05:52 PM

Hello people!

Has anyone tried the Audio Nirvana drivers together with, say, Peter Daniels premium LM3875? I am utterly curios about these drivers, but feel abit torn. I have heard it's love'em or hate'em with these drivers, so I am looking for some educated feedback before I buy an AudioSector kit to go with these..if chip aps and fullrangers are a bad match, I'll have to go with either some other speakers or another amp

Hope someone can share some experience

I don't think there will be any problem except ...........do you really need all that power with efficient speakers.
I use the AN drivers with just 5Watts.
I would have thought the LM1875 would be better.

Perhaps your right, but you know, I have heard they prefer some extra watts. Can't tell you were I read it though.

I wish I knew someone with such an amp, would be great to have a wee bit of listen before I decide...Any chance anyone know somebody with a decent recording mic that have posted a video somewhere?

MO, the chip amps do sound nice, and will certainly get you going. If you consider the costs of the PSU, heatsinks, case etc. the amp modules are only a small part of the overall budget, so as long as you get a big enough enclosure, you can always build a different amp later on using the same parts if you decide the chip amps are not for you. Just go for it.

I have used them with a F2 zen type amp (around 7 watts) and it was fine. Personally, I would go with a min of 20 amps.

I don't think you meant that.

Thanks for the reply, yeah I guess I'll just have to try it out.

I have also used Monarchy audio SM70's Class A monos...bridged...and they were WAY more than enouph. The lowest setting on the pre was too loud :}

Seems to me that the extra power is useful for drums and other struck sounds. Plus, wouldn't using a more powerful amplifier set for lower gain have less noise?

I honestly believe that you will want to adjust the output impedance of the amplifier in order to level the frequency response of a full range speaker driver, with either the simplistic series resistor or with an easy hybrid current drive circuit onto an LM1875.

Some people would purchase amplifiers at random until one of them "agrees" with their full range speakers. That seems to be a "financially inefficient" method of making differences in output impedance.
