Local pickup. Upgrading and no longer need this Alpine X‑W12D4 12‑inch subwoofer, a high‑end X‑Series unit rated at 900 watts RMS (2,700 watts peak) with dual 4‑ohm voice coils.
Unit powers up and receives signal but currently does not produce sound (said to “not work”), so this is being sold as a project / repair / parts sub for an experienced car‑audio or audio‑tech buyer.
High‑quality features:
• 12” pulp‑mica cone with HAMR rubber surround and cast‑aluminum basket
• Dual voice coils, 4‑ohm + 4‑ohm, very popular for wiring flexibility
• 23–200 Hz frequency range, 84.3 dB sensitivity, designed for tight, powerful bass
• Great candidate for a cone/spider/voice‑coil rebuild or parts donor for another X‑Series sub
Condition:
Cosmetically clean; no obvious cone tears, frame damage, or rust on the basket. Voice coil and suspension are intact and centered (as seen in photos). Bottom of the basket is not chipped, and the sub looks like it was lightly used.
Important: This is being sold “as is” with no warranty; it is not tested as fully functional and should only be purchased by someone who can diagnose or repair it.
Why this is a good deal:
• New X‑Series 12‑inch subs like the X‑W12D4 commonly retail around $400–$600+ new.
• A project sub like this can often be rebuilt for a fraction of the cost of buying a new high‑end 12‑inch, especially since the basket, cone, and motor are in one piece.
What you get:
• 1 x Alpine X‑W12D4 12” subwoofer only (no box, mounting hardware, or amplifier)
• Comes as‑seen in photos
Shipping:
• Local pickup preferred (Hagerstown, MD)
No trades or lowballers. Serious buyers only. If you’re a technician, DIY‑audio builder, or subwoofer tech looking for a project driver or parts, this could be a great way to save big vs buying a brand‑new 12” X‑Series.
Price:
Listing at $120 BIN (or best offer) for a non‑working unit. If you’re confident in your ability to test or repair it, you’re getting a top‑end chassis at a deep discount.
