6 ranked speakers support aptX Adaptive, Qualcomm’s variable-bitrate codec. Unlike standard aptX or aptX HD, which run at a fixed bitrate, aptX Adaptive shifts between roughly 279 kbps and 420 kbps in real time depending on radio conditions and content - prioritizing a stable low-latency connection during video or gaming, and higher quality during music playback when the link has headroom to spare. Both ends need aptX Adaptive support specifically; a phone with plain aptX or aptX HD won’t invoke it.
For every aptX variant together, see aptX speakers, or Bluetooth codecs explained for the full picture on why codec choice matters far less on a speaker than on headphones.

Portable Bluetooth Speakers
Medium Size Portable Bluetooth Speakers
Ranked #10 of 142 in Medium Size Portable Bluetooth Speakers, last listed at $395.00 - B&O Beosound A1 2nd gen: $395.00 Amazon eBay
Pros: More neutral than the first A1
Cons: Not stereo. Not as deep bass as the A1. Pumping sound artifacts above 60% volume, only good for lower listening levels.

Ranked #18 of 142 in Medium Size Portable Bluetooth Speakers, last listed at $399.00 - B&O Beosound A1 3rd gen: $399.00 Amazon B&H Photo Video eBay
Pros: Longer battery than the 2nd gen (~24 hours at sensible volumes). IP67 rated with a serviceable, replaceable battery - the first Bluetooth speaker with Cradle to Cradle certification. Multipoint connectivity and aptX Adaptive.
Cons: Distorts easier than the 2nd gen with deeper bass. Dipped area in the upper mids. Not as deep of bass as the 2nd gen

Ranked #35 of 142 in Medium Size Portable Bluetooth Speakers, last listed at $129.00 - Bose Soundlink Flex 2nd gen: $129.00 Amazon eBay
Pros: Pretty much identical sounding to the 1st gen
Cons: Not stereo. Warm sounding with overly boosted bass which drowns out midrange detail. Self drains the battery about 10% a week.

Ranked #76 of 142 in Medium Size Portable Bluetooth Speakers, last listed at $249.99 - KEF Muo gen2: $249.99 Amazon eBay
Pros: KEF seemed to have fixed the rolled off treble and overall balance
Cons: Lacking deeper bass. Very thuddy bass. Appears to be the exact same hardware but with updated tuning. Bass distorts as volume increases, and the claimed 43Hz extension is really only audible at low listening volumes, with a few seconds of lag after volume changes. Loses most of its bass off-axis. Customer reviews are mixed, ranging from praise for detail at low volume to complaints of a boxy, hollow sound.

Powered Speakers
Large Size Powered Desktop Speakers
Ranked #1 of 4 in Large Size Powered Desktop Speakers, last listed at $899.00 - B&W Zeppelin Pro: $899.00 Amazon eBay
Pros: Titanium dome tweeters and an improved 24-bit DAC over the standard Zeppelin for slightly better high-frequency detail on hi-res streams. Dynamic EQ DSP. Customizable downward-firing light. Same wide soundstage and deep bass extension as the standard Zeppelin.
Cons: Same price as the standard Zeppelin for a fairly modest tweeter/DAC upgrade. Nothing besides the lack of battery, lack of waterproofing, high cost and the Earfun Uboom X that’s so close to it in terms of sound quality for 7x less money. Basically an indoor only speaker. Although at this price point I’d generally recommend some Top Recommended Bookshelf Speakers instead which will have even better soundstage.

Ranked #2 of 4 in Large Size Powered Desktop Speakers, last listed at $899.00 - B&W Zeppelin: $899.00 Amazon eBay
Pros: Amazingly neutral, quite a wide soundstage due to the width. Bass extension deeper than all others in category.
Cons: Nothing besides the lack of battery, lack of waterproofing, high cost and the Earfun Uboom X that’s so close to it in terms of sound quality for 7x less money. Basically an indoor only speaker. Although at this price point I’d generally recommend some Top Recommended Bookshelf Speakers instead which will have even better soundstage.
