Brought them in last night and my back is sore now.
Wife helped out but just as a support.
I'm getting old for heavy speakers.
Minor scuffs and scratches but nothing major.
There is one few inches long small crack on top plate of right speaker.
Grills are very good besides minor holes/fraying etc.
Side panels and back cabinets are very good.
Front baffle is almost perfect.
On the left speaker, there is some kind of glue residue around the dimensional driver and some of that glue is also on the surrounds of that driver.
There is no rip or tear on the driver though.
Right PR has small crease on it.
On all drivers' surrounds including PR, there is rusty colored dust layer as seen on the pictures.
Also, that rusty color rings are on the grill cloth from the surrounds touching the grill cloth.
I saw that in my Monitor 7's as well.
Not sure how that rust colored dust gets there but it wipes out clean.
May be it's due to being unused for a while. SDA-2B didn't have that.
They look pretty good after wiping the dust/rust.
Briefly turned them on this morning and noticed these are more efficient than 2B's.
At the same volume, these are noticeably louder than 2B's.
Also, these have smoother/more midrange and more heavy/solid sound.
2B's sound little lighter and thinner but brighter.
Didn't notice much difference in bass but I only listened at low/moderate volume.
I know it's very crappy testing and setup but I was expecting night and day from 2B's.
My living room is now crammed.
I have my work cutout for this weekend moving speakers around.
I'm using IC from CRS+ for now.
From the other thread:
I checked schematics and bi-amp is separated for tweeter and mid drivers.
I was thinking may be few mids + tweeter can be powered independently for upper/mid range and others for low frequencies.
SDA Handbook is downloaded long time back.
Remember, this is my 3rd SDA.
