AVI are stunning, they are the AVI ADM 9.1t's, not to hot in the bass department but will destroy the Mackies in detail, depth, soundstage and give a good run for volume, if they had the bass of the Mackies they would be perfect, the other speaker are, Castle Howard(rear), they have some drivers from the later AVI DM10's shoehorned in the front at the moment but don't quite sound right so am was going to cannibalize the Castles in front of them which are the Chester model(they have the same drivers but only have the front firing and not the twin with upward firing of the Howard's) but when the arrived and I saw the condition I am now having second thoughts, I may put the drivers from the Chester into the Howard's and then play with the Chester's and try to get those AVI drivers to work, it will require a new crossover though, will most likely pair them with a Scanspeak 2905/9500, i think that is the model number, the last speakers at the back are some Ruark Icon's, they are a damn good little speaker.
