What I have are some DC LVL3 10s they were originally LVL3 15s . These have been completely gone thru and have all new soft parts. I put them in classic new 4-spoke frames with custom spacers for adequate cooling, new 8” dual layered spider packs with stitched in leads, new (PE) high temp voice coils, new non-pressed paper pulp cones with medium surround, new real carbon fiber dust caps, new 4-gauge terminals, new rubber gaskets.
They exceed the originals in performance. The thiele-small parameters are slightly different from original LVL3s. New TSPs will be included in box.
