The D48R: full-sized floorstanding speakers that disappear like their famous mini monitors but with the additional might that only big woofers can provide.
ProAc does a better job at integrating the ribbon tweeter than most manufacturers who have attempted this daunting task. ProAc has done their homework here, integrating woofers with ribbon tweeter to perfection. HF extension is tasteful and highly resolving without being harsh or overly forward. This is indeed a ribbon tweeter design that can be enjoyed for long listening sessions without fatigue.
Unlike most slim-footprint floorstanders with side firing woofers that have always proved fussy to set up, the D48R is an incredibly easy speaker to place in the room, thanks to the downward, side-firing woofer ports.
