Wi-Fi Speaker Featuring AirPlay, DLNA, Wireless Direct, HTC Connect and Built-in Subwoofer

We're living in a wireless world. Which is good news for music lovers, because it means now, you can wirelessly enjoy your music wherever you are. And since the smartphone has become the most essential wireless device in your day-to-day life, it was only a matter of time before someone introduced a Wi-Fi speaker with the broadest smartphone connectivity ever. That someone is Pioneer. And that speaker is the new A4 Wireless Speaker: the most convenient source for bringing high fidelity and powerful bass sound to you anywhere you go.

Comprehensive Connectivity

In the wireless world, there are many ways to connect and play, and the A4 connects to virtually all of them. Besides industry-standard DLNA compatibility over Wi-Fi, you can use AirPlay and HTC Connect to play music from your smartphone or tablet PC.

Pandora and vTuner Internet Radio
Pandora and vTuner Internet Radio Available with Firmware Upgrade

Expand your audio entertainment options with an endless playlist of your favorite music and access to more than 10,000 internet radio stations from across the globe. With a firmware update, Pandora and vTuner Internet Radio are now built right into Pioneer's line of SMA wireless speakers and are designed to help you discover and enjoy new music. And with Pioneer's free ControlApp, available in the App Store and Google Play, you can control it all conveniently right from your compatible Apple or Android device.


AirPlay is a revolutionary way of enjoying your music anywhere in your home, and the A4 is AirPlay compatible right out of the box. Wirelessly stream music from your iPhone, iPad, iPod touch, or your iTunes-running Mac or PC directly to the speaker. Plus use your iPhone or iPad device's familiar controls to change the volume and switch songs.

HTC Connect
HTC Connect

HTC Connect is for Android owners who, until now, have constantly asked, "What about me?" The good news is your speaker has arrived. A Pioneer exclusive, the A3 proudly supports HTC Connect, compatible with HTC One series phones. HTC Connect makes it easy to wirelessly stream your favorite music straight from your HTC One phone. There's no need for a separate app; HTC Connect is built right into your phone's music player.

DLNA Certified
DLNA Compliant

Streaming the highest quality music from your laptop, PC, or "smart-device" is the way to the world of audiophile music enjoyment. All of Pioneer's 2012 SMA Wireless Speakers are capable of receiving, decoding, and playing the highest quality uncompressed music files with up to 192kHz sample rates with 24-bit resolutions.

Here's Why Wi-Fi

You don't need limits, especially when it comes to your audio experience. That's why instead of Bluetooth, Pioneer designed the A4 to be a true Wi-Fi speaker. Wi-Fi's higher bandwidth carries more audio signal, giving you higher audio quality. Not to mention far better range unobstructed by things like furniture or walls. Easy to set-up and pair, Wi-Fi gives you the portable audio experience you've always wanted.

Wireless Direct

With Wireless Direct--a Pioneer exclusive--you can enjoy wireless music far beyond your home's wireless network. Wireless Direct allows for a direct wireless connection between your smartphone and the A4 speaker, without the need for a wireless router.

Tuned Personally by Andrew Jones

The A4 has been developed from the ground up by none other than Andrew Jones, world-renowned Chief Speaker Engineer. Having personally chosen the 5-driver design, the A4 comes with dual 77mm midrange speakers, a dedicated 100mm subwoofer and dual 20mm tweeters. The sleek and contemporary A4 not only enjoys a distinguished pedigree, it also offers the clear, natural, and powerful audio experience you expect from Pioneer.

Maximum Sound, Minimalist Look

Before you hear the sound, the first thing you notice about the A4 are the clean, minimalist lines of this extraordinary speaker. Its enclosed gloss black body means a fuller, less distorted sound. The timeless look of its black metal grille adds to the streamlined look, as does the perfectly integrated matte black capacitive touch control panel.

By taking advantage of Pioneers audio heritage, as well as the latest technology, the new, portable Pioneer A4 Wi-Fi Speaker puts the key to wirelessly enjoying your music wherever you are right where it belongs. In your hands.

I wanted to check the state of some new Airplay speakers, so I decided to compare a few of them, namely the:
- Bose SoundLink Air
- Pioneer A4 XW-SMA4-K
- Pioneer A3 XW-SMA3-K
- Logitech Wireless Boombox

Right off the bat, you can notice that the Logitech unit is in a different category. It's much less expensive (1/3 the price) and uses bluetooth rather than Wi-fi. However since it received great reviews online, I decided to compare it as well. I'm glad I did (read on!).

First of all, let's talk about what's common here.
When using a bluetooth speaker (the Logitech here is the only one), you get instantaneous response when you change track, change the volume, press play or stop: that's the beauty of using bluetooth. Also, apparently bluetooth has less bandwidth than wi-fi, so it compresses the music before sending it to the speaker. However in real usage, I could never tell the difference. If you are a real music expert and have an very good musical ear, maybe you can hear it but I certainly could not. All the music I played sounded great whether I played it on the bluetooth Logitech or on the other Airplay speakers.

Using Airplay, you will encounter a delay when you try to control the music. It's around 1 to 2 seconds before any action on your iPod/iPhone will take effect on the speaker (except for Stop and volume changes which are almost instantaneous but not quite). This delay will also occur when you skip songs (something I hate) however it does not occur if your let your playlist continue and your iPod is simply going on from one song to the next. This means if you are throwing a party and try to skip a tune, you will get silence for 2 seconds.

My family and I were also initially unhappy with the overpowering bass of the A4.

There is no tone control with this speaker. While I could try to tweak the settings from my desktop computer's iTunes equalizer, the readings would be different for other sources; i.e., my living room sound system and my desktop computer setup would require different equalizer settings meaning we would have to adjust the equalizer settings before and after each time we used the A4. And, ultimately, neutering almost all of the bass level wasn't a satisfying solution to make the A4 sound better -- it was either too much bass or no bass at all.

I was about to send the A4 back Amazon to exchange it for the A1 model, but then I read less flattering reviews about the A1's sound relative to the A4's, making me feel very much like Goldilocks.

I then went to The Wirecutter website, and read a detailed review of the A4 by Alexander George. In his review, he suggested that I "put a sock in it." Literally. I placed each side of one of my socks in each of the A4's rear bass speaker vents.

OMG! That worked like a charm! You still get the great fidelity. There is appropriate bass, but it no longer sounds like a jackhammer is on the loose. This speaker now sounds wonderful and we couldn't be happier with it. I was so grateful for that suggestion, and wanted to share it here. Try it! In my view, if Pioneer were smart, they would include a black sock in every box!

Let me first tell you why I bought a Pioneer A4 and why I'm so happy with it. Then I'll go over its features and do a little nit-picking, which boils down to "this is an RTFM product in a post-RTFM world." All things considered, I love my A4: it's a great product at a terrific price.

What was I looking for? First, I wanted a self-contained package with a big sound that my friends and family and I can beam music to with Apple's Airplay technology over wifi. Second, I wanted outstanding sound and I didn't want to compromise on bass response. Third, I specifically didn't need a battery powered model. (If I did, I could sacrifice the A4's "subwoofer" and get an A3 for the same price with the same features plus water resistance and a rechargeable battery.) The A4 easily delivers on my three wishes, so I'm delighted with it. It sounds simply terrific for a product of its size, and it does exactly what I want it to. As a bonus, it includes an Ethernet port for improved network reliability, and it's capable of being its own wifi access point for use where there's not an existing network (say, at a vacation house). And its USB port, in addition to providing a direct audio connection for iOS devices, charges them too; I mention this because iPads can be fussy about what they're willing to take a charge from. If you're in an analog mood, there is of course an 1/8" stereo input port in the back. And it comes with an itty-bitty remote control that, when lost forever under a couch cushion, won't render the A4 useless. I like that.

But what about Bluetooth?

I'm listening to music playing on this speaker right now, and it sounds great. The setup was nowhere near as simple or seamless as I would have liked, however.

The first gotcha - this AirPlay speaker doesn't support 802.11n wireless networks. I had an 802.11n only network and spent about 45 minutes trying to get this thing set up on my WiFi with no luck. After pulling my hair out for a while, I switched my network from N only mode to B/G/N mixed network and was finally able to get it connected. That's too bad, my entire wireless network had to be slowed down to support this device. I've been having a fair amount of stuttering and playback problems, even with the speaker and source computer both within 10 feet of my WiFi router. There's a 1-2 second delay in the sound between the computer and the speaker when using AirPlay, so it's tough to sync the audio and video when watching a movie.

My other problem with this speaker is the sound. Out of the box, it's exceptionally "boomy" with very little mid-range. It's terrible for movies and TV, with emphasis on the bass-heavy soundtrack and special effects and mumbled, barely audible dialog.

My solution was to use an EQ application on the source computer use the aux input on the speaker rather than AirPlay. That eliminates the delay and allows me to specify different EQ settings for different types of input. With a bit of EQ fine-tuning, the speaker sounds fantastic and can easily fill a room. We watched a movie last night and everyone was impressed by the volume and clarity of the sound.

I wish this speaker supported wireless N and had an adjustable EQ! But the audio quality, once fine-tuned a little bit, is very good.
