d48r’s were in their usual positions for floorstanders, 30-36 in from both walls
i felt the 48’s boomed a little bit.... i was running the audio research ref 110 at that time... 8x kt120’s have a lil mid bass bloom.. i am pretty sensitive to that... felt the 30’s had less that and also gave the mids and highs a little better focus and imaging with its single mid/bass driver
