And difficult and slow to set-up.

[I have a friend who has had a used one for ages - and still hasn't Dsp'd the room response with it. !!?! yes!]

Especially considering that it seems that the right Mini-DSP box / boxes can do what I want for far less. Even with the price of RTA SW for my tablet, and a test signal source / test CD, and a suitable mike. I have a stand already.

Noting that I doubt I will be eq-ing the 63s much or at all, as they are dipoles,and won't be doing much in the bass. Even if their amps are being fed by a DSp/DAC output signal, I don't want to damage their impulse response with Eq.

The most I am likely to use is a slope-control ? >< to adjust the whole sound for over-bright or dull (old?!) recordings. And that might go in the analogue pre, if Mini-DSP's range can't meet that need.

Or there's D-Speakers latest room-eq device, which does have a slope control?

I Hope to learn a lot from the analogue 1/3rd octave Eq and Diy Swarm subs. There are three stages to that. All using 1/3rd octave eq per channel / even per bass source, when I can scrounge some more.

Stage 1? will use two pairs of the Audiosphere 3s, the speaker I bought instead of a pr of 57s back in the late 1970s, plus another pair since. Two of which IME(&O) do a good enough job on 32ft organ pedal reeds with some room-gain. Fb being 38Hz with a QB3 slope. I won't be using the 20Hz sliders on them, but I will see if a touch of boost at 30Hz helps.

Stage 2 is when I add two sealed DIY (clam-shelled P-P driver) subs, and can give away the newer pair of Audiosphere 3s.

Stage 3 is when I add two tall TL subs using a recent Martin King design and KEF B139s. And can use my original pair of 'sphere 3s for rear surround duty.

I will still have to save up, so it will be a while. :-)!
