KG 5.5 made into a center channel.

[jkjome85]

I just aquired a pair of Medium Oak KG 5.5's, and I hope to someday expand this into a home theatre setup. Researching the forum on center channel speakers matching the KG 5.5's turns up mixed results, but I would like a seamless blend between the front three speakers, so I have decided to build my own custom enclosure with KG 5.5 components, allowing horizontal placement under my tv with the woofers flanking the horn. QUESTION ONE: I may create an enclosure with different dimensions than the original 5.5, but with the same internal volume. Will this have any effect on the sound? QUESTION TWO: Given that I create an enclosure with the same volume, if I place the port in a different location will this have any effect on sound? I have also considered the KG 4,2 components for the center channel, as the horn is the same K-85, which should keep a seamless blend between the three speakers, and the advantage is I would not need to worry about locating a place for the port as these components use a passive radiator. OPINIONS on which components you would use? Thanks! Jordan
