I have noted your past description of DSP5.5kHC being less boomy than DSP5.5k before but I have not made that observation yet.

Neither 5500 was near a corner and the right one was almost in open space (there is a whole room to the right).

Unless I put a 5500HC in each position (standing on end) and/or 5500 a Vertical in the center (on it's side) you can't be sure. But I'm fairly confident that the 5500HC is less boomy than the verticals and I believe it has to do with dual ports, but I can't be sure. Like you said it's a completely different speaker. There may be other aspects that are worse but as far as bass goes 5500HC does great. The ports on the 5500 vertical are right at the floor and there is a "corner" between the floor and the wall. With the 5500HC it's off the floor by 20 inches or so. I'll bet if you raised 5500's a foot they would not be as boomy or put the 5500HC on the floor it would be more boomy. Just a hunch.

So yeah you could call that "placement". But you could call it design too because most people don't put 5500's on pedestals or 5500HC's on the floor. Like perhaps if the rear ports were higher on the 5500's they *MIGHT* not be as boomy. Again just a hunch, not fact. Just me experience that 5500HC wasn't boomy and 5500's (both) were (a LOT of MRC managed to tame them).
