I have a decent amount for sale
I'll start with the Dynaudio:
Used pair MW170 $250. Pics to come
Brand New Pair of MW162 Midbass drivers with grilles. Absolute 10/10 never powered. $350
Used pair of MD100 tweeters. I just swapped these out for a pair of MD102 a couple days ago, so they are up for sale. The cups are from MD102s if you see the sticker on the back, but the tweets themselves are 100s. Grills perfect, some use and solder on back clips, but overall I give these 7/10 rating. Sound Great! $190
My old pair of x250 crossovers. Great shape! $150
I have two Arc KS300.4 available. One was demo'd in my car for 1 hour, and the other is brand new. $250 and $270
Also have a Fosgate RF-BLD line driver used for $45 shipped.
