You did good Danny.

That's the perfect size for:
putting Apogee Stage speakers on top to turn it into Apogee Mini-Grand type of system, or
putting a matching satelite speaker on top with subs standing long for the VonSchweikert/WattPuppy look.

And pretty to boot.  What are the dimensions on that bad boy?  I suspect the amp might be in the far sidewall, otherwise I think it would look sweet standing on end.

I'm guessing it is his standard design doubled up sharing a common center wall.  I'm fixing to put one of these together here pretty soon, and haven't decided if I like the passive radiators on the rear.  The depth of these won't allow much space to the rear wall in my setup, and I might try to put the radiators facing the side walls or make a tower with them all facing foreward.

Danny,

What are your thoughs on this?

So long as the air space is the same and it is well braced and solid then it will be fine.
