Best speaker deal: Save $87 on the Sony ULT Field 5 at Amazon

SAVE $87.04: As of June 10, the Sony ULT Field 5 is down to just $242.95 at Amazon, a 26% drop from its list price of $329.99. That's a new record-low price for the speaker.

Just two months ago, Sony added the ULT Field 5 to its speaker lineup. Just a month later, Amazon dropped its price by 25%. Now another month has passed and, keeping with the pattern, the price has dropped once again.

As of June 10, you can pick up the Sony ULT Field 5 at Amazon for only $142.95. That's 26% off its list price of $329.99 and a new best-ever price for the speaker.

While we haven't had a chance to do hands-on testing with the ULT Field 5, Mashable's Deputy Reviews Editor Miller Kern spent some time with the ULT Field 1 and ULT Field 3 and is impressed with the speakers as a whole. The entire lineup was designed for bass lovers. So, if heavy bass isn't your cup of tea, the ULT Field 5 (or any of the ULT Field speakers for that matter) is probably not for you.

The Field 5 is completely waterproof, dust-proof, and rust-proof, with an IP67 certification. It can stand vertically or lay horizontally to suit your space and comes with a removable shoulder strap. While still technically a portable speaker, it's a bit on the hefty side (about 7.3 pounds) and "would be better for more stationary uses like house parties," Kern writes. The Field 5 also packs a slightly longer battery life than the smaller Field 3 (25 hours versus 24), has more customizable audio, more output, deeper bass, and fun party lights.

Based on the sheer power and impressive bass of the ULT Field speakers we have tested, we don't think you'll be disappointed in the ULT Field 5. And at $87 off, you certainly won't be disappointed in the price.
