Not considering the better bass of the larger speaker (i.e. if you crossed both at 60 or 80 hz), how much better is the OMD-28? How well does the 15 compete with the 28? I know the 28 is better, but would I need to do a/b comparisons to find small details or is the difference immediately apparent?
Sorry for the late post...
I think it depends on your use - HT or Music. I have a pair of both speakers along with several pair of the 5's.
At one time I ran a Parasound 2250 (250w/ch @ 8ohms) to both the 15s and the 28s for music (one pair at a time). Huge difference in sound in the low end for the 28's (IMHO). For HT, didn't notice as much a difference because there's three other speakers in play plus a sub.
In the last month, I moved the 2250 to the office where the 28s are and I'm going through a renaissance revisiting my music collection that's been ripped to ALAC via sonos. I'm actually using the pre-amp portion of my first stereo (NAD 7130) to the 2250 and it sounds amazing. Three years later, falling in love with the 28's again...
My 15's are powered by another parasound amp - 5125 (5 x 125w) and that's suited nicely for both music and HT. When we have parties, we wind up putting the 2 x 15's, 2 x 5's and 1 x c1 in party mode, so there's music enveloping the room, but not overpowering from the 15's...
I don't think the 125w is enough for music with the 28's. I did not do much A/B testing using this amp...
I think it comes down to your personal preference to what the primary use is for and what you have powering them. Don't forget they are bigger: taller, couple inches wider tiny bit deeper and you want to pull them away from the wall...
