Eros by Wayne Jaeschke opinions

[andrew01]

Hi,

I'm after opinions on these speakers especially in comparison
to the Ariels by Lyn Olson and the "Thor".......

Trying to decide which to build - having not actually heard any of them.

Thanks
Andrew

Hi,

One factor to consider is :

(The Eros) is tailored to the impedance requirements of
low-powered tube amps, such as single-ended triodes.

What this means in real English is it has been tweaked to sound
"right" or "best" with an amplifier with significant source impedance.

Disagree. This is an inference that is incorrect.

He means to say that the speaker is an easy load for any amp, even low powered SET amps...

(Closer inspection reveals that his design goals were to revise the crossover such that the speaker's impedance doesn't drop too low below 4 ohms, that doesn't have wild swings in impedance phase angle, AND is remains relatively high in sensitivity)

Disagree.
Its not an inference to assume source impedance affects crossover Q's.

Quote from designer
"My only strong recommendation is to use the lowest gauge foil inductors you can afford (preferably 12 awg copper or better). I tried this design with regular air-core inductors and they seem to veil the upper midrange slightly"

This suggests to me that low feedback ie lower damping factor amps can impact the desired sonic qualities. Tube amps aren't known for lowest output impedances. So probably not best suited for toobs.
Looking at the final impedance chart suggests highish F3, so maybe bass shy for some.
