Zen V4 and 16 ohm speakers

[selder]

I've searched. I really have.
I've found numerous posts regarding the Zen V4 with 4 ohm speakers.
What about 16 ohm?
Thanks,
Steve

Hello Steve,

The 16 Ohm speakers would work fine with
the Zen-V4 amplifier.
I tried it, and it sounds very good.

Does this mean that a 16 ohm speaker will play louder than 8 and 4 ohms speakers on the same Zen 4 curent...? Simple Ohms Law I guess.

I have understood that the specified sensitivity (dB) explains the loudness of the speaker, while the specified impedance (ohm) is reference to the choice of amplifier having proper damping factor and output signal current (and voltage) supply.

Here we could read an interesting information about the proper speaker selection.

JH, in 1977 I did in fact build some very efficient Lowther horns.
I made them 1,5 times normal size so they were monsters. Two meters high, 100 kilo each with folded horns in concrete.

I sold these dinosaurs many years ago and wouldn't go into such a project today, cause I don't want to use so much room for hifi anymore. What I'm looking for now are small DIY enclosures, booksleves size, with high efficiency to go with a cute little Zen 4

Ah... I did not know that.
Since the article, Some Insight into Proper Speaker Selection, on the above quoted web page was useful read for me, I just thought that it would be also interesting for you.

JH, thanks for the link, l'm sure it will be interesting reading.

Thanks for your replies......
I'm afraid that I should rephrase my question.

I have the opportunity to purchase some drivers which I'll use in the 100 - 1000 Hz range. I can have them in 8 or 16 ohm. Assuming all other factors to be equal, would I expect the Zen V4 to perform worse, better, or the same with 16 ohm vs 8 ohm?
Thanks again,
Steve

You will definitely experience lower distortion into
16 ohms, but also about 1/2 the power.

Zen V4 AND 16 ohm speakers

I just received my Q Pack and boards last weeek for the Pearl and P. Zen. This is great.
My speakers use 15 ohm Lowther drivers and I am planning on making couple of changes to reflect these conditions.
1. Drop the current to 1 amp with a 0.67 ohm resistor.
2. Only use one power transformer because of the lower power demand.
3. May try using a smaller output coupling cap. Thinking of 4700, or some other value.
4. Reduced power output is not a problem, 3 watts is plenty for my system.
Are there any other parts values that could be changed to help the amp work better into a high impedance and low power application?

Please keep us updated on how things turn out for you. This sounds really interesting. Please also post your evaluation of the Zen 4 and Lowther combination
