Rated 5 out of 5 by from Excellent replacement for mid in dbx Soundefield VReplaced midrange 8" drivers in dbx Soundfield V speakers (I am the original owner). the surrounds were completely rotted out after 20+ years. This driver was much more accurate---very natural sounding. Very clean. Did not upset the balance with the top-mountd ambiance drivers of this "Soundfield" speaker. Much larger magnets, much heavier than the "cheap" midrange drivers they replaced. All dbx Soundfield Vs would benefit from this upgrade---they sound even better than they did even new.

Rated 4 out of 5 by from In Car doorsI have one in each door; they sound clear but lacks midbass, it's more for vocals and high-mids. Overal they are great for the money but you will not get a low mids or mid bass from them... 125RMS on each.
