These are not really the same size class, and that is the honest framing here. The Marshall Middleton ranks #34 of 97 large speakers by sound quality at $211.83; the Marshall Bromley 750 ranks #12 of 12 large party speakers by sound quality at $999.95.
The Marshall Middleton 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 IPX7 against IP54 for the Marshall Bromley 750. The catch: 5db dip at 1.7kHz and 6.3kHz.
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 Middleton. It supports AAC Bluetooth, which the Marshall Middleton lacks. It has an adjustable EQ, which the Marshall Middleton lacks. The catch: Not as deep bass as the JBL Partybox 330 or JBL Partybox 720.
Buy the Marshall Middleton at $211.83 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 Middleton: $211.83 Amazon eBay
Newer model: the Marshall Middleton II, ranked higher, rated 4.1/5.
Pros: Very deep bass for the size/weight. Measured bass extension of 39Hz (-10dB).
Cons: 5db dip at 1.7kHz and 6.3kHz. 9kHz treble peak. Not a very smooth frequency response. A lot of Marshall’s added dsp echo which cannot be turned off, very distracting and annoying. It’s like forcing you to listen to your music in an echo chamber. Bass is reasonably deep but artificial sounding and flabby, with no attack and no dynamics. Treble is rolled off.

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.
