Short answer: the Marshall Stockwell 2. It ranks #11 of 77 large speakers by sound quality at $200; the Marshall Kilburn II ranks #36 and costs $279, so there is little reason to consider the other one.
What the Marshall Stockwell 2 offers: Possibly the most natural sounding Marshall speaker. Excellent off-axis. Watch for: Not stereo. Not very loud. Uses added DSP reverb which audio purists may find annoying.
What the Marshall Kilburn II offers: 20W Class D amp + dual 8W tweeters. 20+ hour battery with quick-charge (20 min charges 3 hours of play). Rugged design with leather handle and reinforced corners, IPX2 rated. Thrives with rock music. Bluetooth 5.0 with 30ft range. Watch for: Boosted upper bass, not very detailed, not as deep bass as competitors, upper mids peak. Very low IPX2 water rating. AC charging
Buy the Marshall Stockwell 2. It ranks higher for sound quality than the Marshall Kilburn II and costs less, so the other one has nothing left to offer.
