Orpheans, Oris, Quasars and Amps (BD-Design)

Hi Richard,

Welcome to the club!

My budget is limited so I am disinclined to go with the Oris as the
drivers are expensive. Love to but has low WAF.:broken:

We do not want you to fight your wife, no need either as the Quasar and the Orphean are not huge and will fit nicely in your listening room. I am sure that many among us are jealous about your room!

I like the look of the Quasars and have the space (5.5 x 8 m). I
understand the OB may lack a little punch of a horn.

It will be less and not just because it does not use a horn but also because the drivers have to work harder due to the cancellation which is inherent to the OB design. They will surprise you anyhow though as the used drivers are not common hifi...

I have wondered about the Orpheans as the price is not too high. But the
114 dB/W/m is scary. What powered amps are people using for these? I
have a 20 W/ch amd was thinking of building a kit LD 300B SE amp with
about 9 W/ch. These amps might be far too much and need to have a lot of
attenuation.

The sensitivity is only scary if you give them the power...

But since amplifiers usually have a volume control then this can be prevented making it possible to connect a 1W or a 1000W amplifier. Quality is what counts, not the power rating. The only problem could be the input sensitivity of the chain making it more difficult to attenuate precisely as it might play too loud for a certain setting.

Using a passive pre-amplifier (no gain e.g. the CrazyV) usually helps.

Would the BD reference bass speaker be a good match for the Orpheans?

Yes and if the WAV allowed then the Ultra version will be optimal.

Later, is it an idea to add a sub? Any suggestions as I understand most
caNot keep up with BD speakers. I notice you feel live drums yet my
current system and others I have heard (SS and standard electrodynamic
speakers) do not give this. Is it practical to get more realism? Do BD
speakers do so anyway?

Adding a sub does do good things but only if there is something present in the recording providing those sub frequencies. For most music the Ultra is sufficient... :wink:
