These sit in different size classes, so this is not a straight ranking comparison. The Marshall Stockwell II ranks #11 of 97 large speakers by sound quality at $229.99; the Marshall Bromley 750 ranks #12 of 12 large party speakers by sound quality at $999.95.
The Marshall Stockwell II is the lighter choice. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. At 3.1 lbs (1.4 kg) it weighs much less than the Marshall Bromley 750 at 52.7 lbs (23.9 kg). The tradeoff: Not very loud, and the added DSP reverb may annoy purists.
The Marshall Bromley 750 is the longer-running choice. Much wider, more consistent off-axis dispersion than the JBL Partybox 720, which only fires forward: the Marshall’s standout feature, sounding about the same from any angle. It is rated for 40 hours of battery against 20 for the Marshall Stockwell II. It supports AAC Bluetooth, which the Marshall Stockwell II lacks. It links with other speakers (Auracast), which the Marshall Stockwell II cannot. The catch: Not as deep bass as the JBL Partybox 330 or JBL Partybox 720.
Buy the Marshall Stockwell II at $229.99 if you want a large speaker. Buy the Marshall Bromley 750 at $999.95 if you want a large party speaker instead.

The Two Speakers In Full
Marshall Stockwell II: $229.99 Amazon eBay
Newer model: the Marshall Stockwell III, ranked lower, rated 3/5.
Pros: Marshall Stockwell II uses 3” woofer, 2x 2” fullrange tweeters. Its 1.4 kg, claimed 20 hours (Manufacturer specified) battery life, IPX4 protection, aux input, up to 96dB and mono playback make it a practical option for its intended room or portable use. Possibly the most natural sounding Marshall speaker, with excellent off-axis sound. Measured bass extension of 44Hz (-10dB).
Cons: Bass is limited by its 44Hz specification. There is no companion app. No EQ adjustment. Not very loud, and the added DSP reverb may annoy purists.

Marshall Bromley 750: $999.95 Amazon eBay
Pros: Much wider, more consistent off-axis dispersion than the JBL Partybox 720, which only fires forward: the Marshall’s standout feature, sounding about the same from any angle.
Cons: Not as deep bass as the JBL Partybox 330 or JBL Partybox 720. Not a great frequency response overall, with some midrange peaks. Only basic bass/treble controls, no full custom EQ like the JBL Partybox 720’s app. Default bass (dynamic mode) is overdone out of the box and needs trimming.
