Short answer: both are discontinued, so this only matters if you are buying used. Used, the Argon Audio 6350 is the better pick: it ranks #97 of 144 bookshelf speakers by sound quality (rated 3.1/5), against #103 (rated 3.0/5) for the Argon Audio 6340. If you want one new, the Neumi BS5 ranks #38 at $139.99.
The case for the Argon Audio 6350: A budget two-way with a 5.25” woofer and a 1” tweeter. The catch: The on-axis response is uneven (1.74 average deviation), sensitivity is low at 85dB and the load is 4 ohms.
The case for the Argon Audio 6340: A small budget two-way with a 4” woofer and a 3/4” tweeter. Watch for: The on-axis response is uneven (1.18 average deviation), sensitivity is low at 84dB and the load is 4 ohms.
Buy the Argon Audio 6350 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 Neumi BS5 instead.

Argon Audio 6350: $174 per pair Discontinued eBay
Pros: A budget two-way with a 5.25” woofer and a 1” tweeter. Measurements show a preference score of 4.38 that reaches 6.87 with an ideal subwoofer, with 0.41 listening window deviation. Measured bass extension of 75.5Hz (-3dB).
Cons: The on-axis response is uneven (1.74 average deviation), sensitivity is low at 85dB and the load is 4 ohms. Argon no longer sells it. Bass reaches 75.5Hz (-3dB) and about 50Hz (-10dB). That data is low quality. Discontinued.
