These are not really the same size class, and that is the honest framing here. The Marshall Middleton II ranks #31 of 97 large speakers by sound quality at $330; the Marshall Bromley 750 ranks #12 of 12 large party speakers by sound quality at $999.95.
The Marshall Middleton II is the lighter, tougher option. Very deep bass for the size/weight. At 4 lbs (1.8 kg) it weighs much less than the Marshall Bromley 750 at 52.7 lbs (23.9 kg). It is rated IP67 against IP54 for the Marshall Bromley 750. Watch for: Bass boosted which drowns out the midrange.
The Marshall Bromley 750 is the longer-running pick. 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 30 for the Marshall Middleton II. It supports AAC Bluetooth, which the Marshall Middleton II lacks. The tradeoff: Not as deep bass as the JBL Partybox 330 or JBL Partybox 720.
Buy the Marshall Middleton II ($330) for a large speaker; the Marshall Bromley 750 ($999.95) suits a large party speaker instead.

The Two Speakers In Full
Marshall Middleton II: $330 Amazon eBay
Older model: the Marshall Middleton (ranked lower, rated 4/5).
Pros: Very deep bass for the size/weight. Measured bass extension of 38Hz (-10dB).
Cons: Bass boosted which drowns out the midrange. Dip around 200Hz, peak at 1kHz, dipped at 1.6kHz. Strange frequency response through the mids.

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.
