Stefano Bertoncello's posted at his blog a comment about Tony’s playback. I do not know him; I guess he is an Italian fellow or somewhere near Italy.

It is 4-ways bi-amped playback, with multi-sell at lower MF, dual-driver ported enclosure at the bottom and two Goto above. The multi-sell is driven by Altec 288; I guess down to 400Hz. The bass is from par of Altec 416, a sort of blow up Altec 19 type of bass. The result is not overly extended very manageable, easy to use configuration.

Twogoodears, look like he liked the sound, that’s he did not described it a lot not did he described what Tony’s intended to do. But again, it is a private blog and Twogoodears is perfectly entitled to write in there whatever he wants.  Some comments:

Tony needs to move the TT from the wall a bit. The corner that TT and wall shape is a location where the pressure collects and it is right where the tonearm is.  Moring the TT for 10” ahead and creation a chenals between TT and wall would eliminate this problem.  The first order filtration and not time aligned – come on, get stereos!  I do like where the mouth of the MF Goto located. Probably I would go for a bit longer horn with lower cut off to make the horn to hang over the bass bin.  From a different perspective why Tony put the MF Goto where he put it, it is time not aligned anyhow?I do not see any means to assure that the wooden stacks that stupors Goto driver are parallel, in fact even on the picture they are not parallel. Dose Tony uses axis bending and a compensation for time miss-alignment? It would be a legitimate thing to do it he listen from fixed distance but I do not think he does.

Anyhow, what I do like in this playback is the bass section and the way how it connected with multi-sell. I am not a bit multi-sell fun but in a large room then might work more or less OK. This multi-sell can handle more bass then Altec 288 can care, I guess it would be interning to drive it down to full 250Hz with more LF capable driver if to find one. It would be interesting to use in bass bin not 416 bass drivers but the 515B or E (ferrite version of B). They have 15Hz lower resonance frequency and might yield more bass from the same box (the port would need to be retuned).

The class D amp driving the Altec 416, ehhhh!
