Sony ULT TOWER 9AC vs Marshall Bromley 750

The Sony ULT TOWER 9AC is heavier and larger than the Marshall Bromley 750. Perhaps unsurprisingly, then, it puts out more low-end and gets louder. Even though the Sony speaker has two tweeters facing rearward and is advertised to offer 360-degree sound, in practice, your listening angle still affects the sound you hear. This is much less true with the Marshall, which sounds fairly similar regardless of your listening angle. The Marshall also runs on battery power, which might be the decisive factor if you plan to soundtrack a garden party BBQ using this speaker.
