HEDD Type 20 Mk II left side speaker. Sounds great and is in good cosmetic condition - just some light scuffs and dings from being moved around. Does not include the bass port plug but HEDD sells them for $50 if you want to use it in the optional closed port configuration. There are several right side open boxes currently available, for example Perfect Circuit has one here on Reverb for $1809. Purchased together, you'd have an awesome set of monitors for a great price!
