Marshall Middleton vs Zealot S67

Last updated: August 28, 2026

Short answer: the Marshall Middleton for better sound quality, the Zealot S67 for the lower price. The Marshall Middleton ranks #31 of 77 large speakers at $224.90. The Zealot S67 ranks #76 at $80, $144.90 cheaper.

What the Marshall Middleton offers: Very deep bass for the size/weight. Watch for: 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.

What the Zealot S67 offers: 60W output power, 20-hour battery life, IPX6 waterproof, Bluetooth 5.2, TWS stereo pairing, EQ with 3 sound modes, dual drivers with passive radiator, MicroSD and AUX support, built-in microphone, USB-C charging Watch for: A lot of distortion above 50%, no deep bass, rolled off treble. Just not a good sounding speaker.

Buy the Marshall Middleton when sound quality outweighs the price for you, and the Zealot S67 when the price outweighs sound quality instead.

If sound quality matters at all to you, skip the Zealot S67. It ranks near the bottom of the 77 large speakers, so look higher up the list instead.
