Review: Pioneer A4 WiFi Speaker

Review: Pioneer A4 WiFi Speaker

I received the Pioneer A4 as a Christmas gift last year. I was so excited that I opened it to start messing with it before I even got home. After messing around for 10 minutes before finally playing the only audio file that exists on my phone (a voicemail) on the speaker. My experience quickly revealed several of the shortcomings I would be working through in the following weeks.

The A4 has 5 speakers: 2 tweeters, two woofers, and a 4” subwoofer between them. Connectivity is via USB, Ethernet, WiFi, and an Auxiliary input. Music streaming is via either Airplay or dlna, and there is no Bluetooth connectivity. Following a firmware upgrade offered after I got the speaker, there is also an iPhone/Android app that runs Pandora and Spotify directly on the speaker.

Step one: Connect to the WiFi network.

Upon unboxing the Pioneer A4, I was met with the speaker, a power supply, and a getting started guide. The getting started guide is massive, and contains an incredibly complex flow chart which explains how to get started. After spending a good 5-10 minutes deciphering it all, I decided to use the quick connect feature, which makes the speaker its own WiFi access point. I was able to get that audio file to play on the speaker before I decided it was best to box it back up and try again when I was in my own house. Setting up the WiFi manually comprises activating quick connect mode, browsing to the setup page, setting the WiFi details, and rebooting the speaker. I chose to take a shortcut by connection my wife’s iPhone to it via USB. Upon connecting, the phone will ask if you would like to share the WiFi connection data. All you have to do is say yes and voila! It’s connected. This feature should be front and center in a much smaller getting started guide!

Step Two: Play some music.

I’m an Android user, and I quickly realized from the getting started guide that Android devices are second class citizens on the A4. With that in mind, I decided we should start with the iPhone. My wife opened Pandora, started some music playing, and we noticed a little icon on the volume slider (the Airplay icon, of course). We touched the icon, and selected ‘Pioneer A4’, which was the only option. Within seconds the music stopped playing on the phone and was instead coming from the A4. Success!

If I was an iPhone user, this would be it. I would be done, and it would be time to review the audio quality. There are two reasons why we’re not there yet. First, I’m not an iPhone user. Second, Pandora doesn’t exactly translate to high quality audio. There was one more (lengthy) step in this process.

I like Spotify. I like choosing the actual songs I want to play, I like listening to complete albums, and I like the audio quality. It’s still digitally compressed, but I don’t hear artifacts even in most cymbal hits, so I’m happy with the compromise of more music for less than CD quality. Don’t get me wrong, I can be incredibly objective and I’m sure if I ran a CD against the same tunes from Spotify I would hear all kinds of shortcomings, but it’s still a compromise I can live with. I wanted Spotify on my A4, and I didn’t want to make a playlist for every album I wanted to listen to. Yes there’s a phone app, but the phone app for Spotify free requires playlist creation and plays the playlist in random order. I really needed to stream Spotify from my laptop to the speaker. Thankfully there are several ways someone can do this, but I chose ‘Stream What You Hear’, which is a free dlna streaming application. Another recommended option was Air Parrot, but that was $15 and did a full display mirroring, so it was overkill and not free. I really wish this speaker supported Bluetooth, but there are inexpensive Bluetooth receivers available that can fill this void. I plan to get one soon.

Listening Test

So, now the speaker is in my bathroom so I can play music while I get ready in the morning. This is exactly what I wanted. The tiny iPod dock I had before was incredibly disappointing in so many ways, and it was time for an upgrade. I have music streaming to it from my laptop, which is playing anything I want off of Spotify, and iTunes can stream to it via airplay if I want to play one of my CDs which is ripped in iTunes (iTunes is on our iMac – I didn’t check to see if Windows iTunes supports Airplay). It’s time for the listening test!

My first impression: Way too much bass! Where is the sub volume control? I had a hard time getting past this issue. There was no way I was going to be able to place the speaker 2 feet away from any wall, so that amplified the bass even more. Why doesn’t the A4 have a subwoofer level adjustment? Placement affects bass significantly. What if I had put this in a corner? It’s a small speaker. It needs to be adaptable to less than ideal room placements. I have great news, though. Pioneer designed the A4 with a pair of symmetrical rear-firing ports. While this probably makes placement issues worse, it provides an opportunity to correct them as well. How? With a sock. Yes kids, that’s right. Put a sock in it. I found that in my application I like to have a sock stuffed into one of the ports. Other people have reported stuffing a sock into both sides (you can still use the one sock for this), but in my application that made the bass a little too weak.

Don’t expect miracles from this little speaker, but do expect some quality sound and good volume capacity. Because there are enough speakers to share the burden, compression is minimal even at elevated volumes, both in the high and low frequencies. As expected, the subwoofer doesn’t get exceptionally low, but it is clean, not too boomy, and generally satisfies. I do experience some fatigue after listening for a while at higher volumes, but at this price range I would be shocked if I didn’t. It is competent playing anything from Eminem to Megadeth, and no issues have stood out sonically. The DAC, amplifiers and speakers all work well together and deliver a very enjoyable experience from a small wifi speaker.

The Verdict

My final recommendation is that if you have an iPhone and are in the market for an Airplay speaker, get it. Get it now. If you are an Android user or you want to stream music from your computer, then you should evaluate your tolerance for complex setups. Once you’re all hooked up and streaming, you’ll love it.

HiFi on a Budget

Welcome

About this Blog

While many of my friends believe I spend too much money on my audio equipment, my friends who are very active in hifi audio don't hesitate to call me a cheap ass. I buy a lot of used and closeout gear and my TV is a Dynex (the TV is the lowest on my list of priorities). Hifi on the cheap is not something one could easily do in the past, but thankfully between modern amplifier technologies, manufacturing advancements and of course the internet, we have access to a world of affordable high quality gear. There are entire web stores dedicated to selling closeouts of hifi audio equipment. There is a huge market of used products through Audiogon and eBay. Every once in a while you can even work a deal at Best Buy's Magnolia store, but that's a more traditional route.

It is my goal to share with you my experiences as I go. I will do my best to be unbiased, discerning and picky. I have learned many things in a short time, and I plan to learn a lot more as I go. Again I will share as much as I can along the way. If I help you put together a quality hifi system for a reasonable price, then I've done my job. Please feel free to ask any questions in the comments and I'll do my best to answer those as well.

There are a few up and coming reviews I'll have, and I'll also be reviewing the gear I already own. Here's a rundown of the gear I'm currently running. This changes pretty regularly, and I'll do my best to update on the changes I make and why I make them.

Primary TV

  • Dynex 40 Inch 1080P (I really am cheap sometimes)
  • Sony Blu-Ray Player
  • Emotiva UMC-1
  • B&K TX4430 200Wx3 - driving the front 3
  • Lepai 20Wx2 Tripath - driving the surrounds
  • L/R - Focal Chorus 726V Towers
  • Center - Focal Chorus CC701V
  • Surrounds - Jamo C60 SUR
  • Sub - Definitive Technology Supercube 6000

Secondary TV

  • Another Dynex 40 Inch 1080P
  • Samsung Crystal Surround Air Track

Other

  • Pioneer A4 Wireless Speaker
  • Weak shelf system running a pair of poorly crossed over Onkyo HTIB front speakers
As you can see, there are some quality items in the list, and some items which need to be replaced. The lepai amp is high on the list. I opted for a 3x200W amp to drive my front 3 with the intention of getting a more powerful stereo amp for the towers and moving two of the 3x200W channels to the surrounds. The lepai was running a couple of Energy Take 1 speakers as part of my PC audio setup, but since I replaced my Marantz reciever (used only as an amp) with the B&K, I needed something to run the surrounds. Luckily since they don't see a lot of action it doesn't hurt me too badly to have an amp which has a hard time running at reference levels.

I have a Jamo SUB800 on the way which I picked up used on eBay. The PC system was using an old Onkyo 8" sub, which is bulky and boomy, so I wanted to replace that. Once I free up the Lepai I can evaluate the sub. More on that when it happens.

Getting Started with Helicopters

Why Helicopters?

I got a helicopter for Christmas last year. I flew it for a few minutes and I was hooked. I have 4 helicopters and a quad copter now. I'm waiting for warmer weather so I can enjoy some outdoor flying time. I can't wait.

Getting Started

There is one absolute truth in RC helicopters. You will crash. Often. It's best to concentrate less on preventing crashes and more on buying helicopters which stand up to the abuse and beg for more. Save the fragile helicopters for when you have the skills to fly them (I don't), and remember: don't fly it if you can't afford to crash it.

With that said, where do we start? First of all, there are several configurations available for helicopters, and there are toy grade and hobby grade birds. The important thing about toy grade birds is that they often don't have adequate controls to really enjoy flying for more than a few sessions. They get boring very quickly because they lack the controls that make helicopters so fun to fly in the first place.

The helicopters you want to avoid at all costs are 2 channels. These are the ones you'll find at big box stores for $15-$30, and they're not even worth $5. They are capable of two controls: Blade speed and Yaw (rotation). They cannot go forward, backward, or to either side. How are you supposed to have fun going straight up, drifting in the air currents until you're too close to an obstacle, then cutting the power so you don't destroy the blades?

The 3 channel improves upon the 2 channel by adding the ability to pitch forward and back. This allows enough motion to actually enjoy flying. So why don't I recommend them to a beginner? Because they teach you the wrong controls, and the way they pitch forward and backward affects lift differently than with more sophisticated birds. Ultimately you don't learn very much that can be carried onto more advanced helicopters with a 3 channel, and can establish bad habits which you would need to unlearn later. My Christmas present was a Syma 107G 3 channel. When I got my 4 channel I made several mistakes because of what I learned on the 3 channel.

Getting the Right First Helicopter

So we know what to avoid, but where do we start? We start with a 4 channel coaxial swash plate controlled bird, like the toy grade Syma 800G or the pricier hobby grade Blade McX2. I haven't actually purchased either one, so read the reviews and make your own decision. I'm certain I will own one of those at some point, but it will probably be a Blade because it uses radio control, where the Syma uses infrared, which sets off my smoke alarm test (not fun when you don't know why it's going off and it's also your CO detector!). If you're feeling adventurous, get a WL Toys v911, but expect to crash it a lot in the beginning. Since it's a single rotor it isn't nearly as stable as a coaxial and is much more responsive to subtle inputs. I do have one of those and it's a great, inexpensive indoor bird.

There are plenty of guides about the lessons you should work on between crash sessions to become a better pilot, but what makes coaxial helicopters so nice is they're remarkably stable. 6 channel collective pitch helicopters (the real deal) don't self-stabilize. When you get your first heli, try this: Get it up in the air where there's room to fly around, then run it fast in any direction. Let off the stick. The helicopter quickly decelerates and goes back into a hover. The throttle may need correction to maintain height, but it's stable. This doesn't happen on higher end birds, and the lessons you work through on your stable heli will save you from several crashes later on.

Feel free to pick up a quad copter if you're interested, they are more stable in some ways, but if you get a tiny one like the Estes ProtoX, it is very susceptible to air currents. They also don't self-correct as quickly as a coax helicopter, so if you get them going fast, don't expect them to stop on a dime. I crashed mine several times thinking I had enough room to slow it down when I didn't. I recommend WL toys for an inexpensive quad copter. Again I don't own one yet, so read reviews and make your own judgments.

My Current Fleet

  • Syma 107G
  • WL Toys v911
  • WL Toys v955
  • Estes ProtoX
  • Blade CP <- this is a 6 channel collective pitch, which I got used (almost free) and have not flown yet
