Short answer: the JBL Partybox 300 for tuning. The Sony XP700 has dual 6.69-inch woofers and multi-tweeter X-Balanced Speaker Units with a rear tweeter for a 360 effect, but the source flags a weird midrange peak. The 300 has exceptional sound quality with crisp, crystal clear highs and midranges and hard punchy bass without muddiness, though it is hard to carry, too tall and drags on the ground.
Buy the JBL Partybox 300 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the JBL Partybox Club 120 instead.

Multiple inputs (RCA, USB, 3.5mm aux, mic, guitar). LED light modes (meter/pulse/party). True Wireless Stereo pairing up to 2 units. Measured bass extension of 40Hz (-10dB).
