Multi-Room Audio Streaming with Spotify

From the first time we viewed Lindsay Station I have been thinking panicking about audio. We are far from audiophiles but we enjoy music and what a better time to plan an audio system than when the house is gutted. I just hope I get it right.

I started doing some research and had an extremely hard time finding a solution that seemed reasonable. When you search for “Multi-Room Audio” or “Whole Home Audio” articles typically come in two flavors:

1. The traditional audio system: Typically a system that is housed in the basement due to the large amount of cables, very expensive equipment, and cat5 cable. The cat5 cable powers and transfers data between the system and LCD panels mounted on the wall of multiple rooms. The LCD panel is the primary method for selecting and changing music.

2. Sonos: This is the other most common solution and seems to get great reviews. Sonos has stand alone speakers that jump on your network. They also have an amp that connect to a pair of speakers you already own.

I have some major issues with these solutions: I have wifi so I am not running cat5. I am not getting up to change the song on an LCD panel. I am not paying thousands of dollars for amps alone (In my system I would need $3,500 worth of Sonos Amps.)

Must haves: Affordable solution that works across my network. Reasonable power. The ability to control everything from my phone (specifically Spotify.)

BTW… when you ask friends if they have any suggestions they 1. most certainly have never done this before or 2. they suggest Bluetooth solutions. Have you ever walked around a house with your phone connected to bluetooth? Insert eye roll emoji.


Where do we want speakers?

The first thing we did was think about where we want speakers. This is crucial in determining what kind of equipment you will need. We decided that the majority of speakers will be on the first floor as our primary use of the sound system will be for entertaining. For casual use we are more likely to use our Alexa. We also decided not to put more than 2 speakers per room. Crossing our fingers the entire time that it is enough sound for a party.

  • 1st Floor Kitchen, Dining Room, and Parlor: 2 in ceiling speakers each
  • Living Room: 2 in ceiling speakers plus a 6 speaker surround sound
  • Master Bedroom and Master Bath: 2 in ceiling speakers each
  • Total in ceiling speakers: 6 pairs

We decided against placing speakers in the front hall and second floor landing, the first floor 1/2 bath, and outside. We will most certainly regret not having speakers outside. In the attic we will likely throw an Alexa.


What combination of speakers will we want to listen to at once?

This is another aspect to consider. I think when in party mode we will want all of the speakers going at once. I can think of plenty of scenarios when this would not be true. These are the combinations that we determined:

  • Whole House: All of the in ceiling speakers + living room surround sound. Party Mode
  • First Floor Only: Seems like an obvious one
  • Master Bedroom Only, Master Bathroom Only

The Learning Curve.

This is where things got hard for me. I have no idea how amp power is measured, and more importantly, how it relates to speakers. If you asked me this question I would have a same face as my grandmother if you asked her the amount of RAM she would need to play Facebook. Not amused.

I started watching Youtube videos about how Ohms and Frequency Response are related and how the number of speakers yada yada. The issue with most of these videos is that they often make an assumption about what you already know so I was lost OR they kept it so basic that it was not practical.

I tried to run my questions by Crutchfield Home Audio Design Team but they seem to be way over capacity and unable to help. I tried general chat support and was directed to Home Audio team (catch 22) but the guy was nice enough to say “ya that equipment should work fine.”


Powering the System.

I decided that overthinking this was going to cause a panic attack and that it will likely turn out just fine. I started looking for amplifiers and landed on a 12 channel (meaning 12 speakers or 6 pairs) system. The best option I came across was the Dayton Audio MA1240a Multi-Zone 12 Channel AmplifierThis bad boy only costs $500 and has decent reviews. Turns out that I first came across the same hardware with a different brand name (AudioSource) for $160 more. Thank you Amazon comments.

Features:
1. 1200 Amps (ok, seems like a large enough number)
2. Powers 6 pairs of speakers
3. Each speaker pair can play music from Input (Bus) A or B by flipping a little switch or by its own source (this is key for setting up my speaker combinations)
4. It turns off automatically if there is no input so you do not need easy access to the box
5. Purchased from Amazon it will be easy to return if it is not powerful enough or breaks

Downfall: The Amp only allows for RCA input and does not have a optical input. I think this is ok because the Chromcast (discussed later) DAC is pretty solid.


Speakers.

When choosing speakers I decided to look at Crutchfield. I have used Crutchfield in the past along with Monoprice when looking at speakers/amps and have had pretty good luck. Crutchfield pushed Polk speakers to the top of its list and features them as most popular.

When looking at the various options for in ceiling speakers I considered price and size. The larger speakers (8″ vs 6.5″woofer for instance) have better bass due to the size of the cone. It looks like the tweeter also jumps from 3/4″ to 1″.

I decided to go with the Polk Audio RC80i which are 8″ white in ceiling speakers sold in a pair for $150. They are moisture resistant and should be safe in the bathroom. They have 190 reviews and 5 stars with a Lifetime Warranty. The tweeter can be rotated to point to the middle of the room which is pretty neat and you can paint the grills which blows my mind.


Speaker Wire.

I did a Google search for what type of speaker wire should be used. Speaker wire is most commonly 12, 14, or 16 gauge. The smaller the number the thicker the wire. As it turns out for runs >50 ft its recommended to use 12 or 14 gauge. For <50 ft or for 8ohm speakers (which is what I purchased) use 16 gauge wire. I have decided to cut the difference and go with 14 gauge.

This wire by InstallGear was affordable at $30/100 feet and is rated for in wall installation. I am not sure if it is required by code but willing to pay the extra $10 to not risk it.


Streaming Audio to the Amplifier.

The amplifier has multiple options for inputs as discussed above. Due to my combinations I figure I will need a Bus A input source for the largest group (Kitchen, Living Room, Dining, and Parlor) and I will need individual inputs for the Master Bedroom and Master Bathroom. As a result I will order 3 Google Chromcast Audio pucks at $35/each.

Im pumped about this. I will use RCA ables to attach a Chromecast to Bus A, Master Bedroom, and Master Bath. During Setup you add the pucks to your wifi network and label them with a name. At the same time you are able to make custom combinations of pucks which will also have their own name. For instance, “Whole House” will stream to puck 1+2+3 and play on the First Floor, Master Bedroom and Master Bath or “Master” will play puck 2+3 which power the Master Bed and Bath. If you are feeling fancy, you can stream different music to two Chromecasts at the same time (from different devices.)

Volume. The phone/device volume will control the music volume via Spotify. The amp also allows for volume control to each individual channel. I plan on setting the Amp volume to the maximum volume that I would like while the Spotify app is at 100%.

All of the arrangements you create on setup will show up in your Spotify app. IT IS BRILLIANT.


Everything is on order and will cost around $1550 which is fairly reasonable given the amount of sound you will be able to push through the entire house. The best part… the wire is in the walls and wont go bad, you can always upgrade components later.

    YOU’RE A WIZARD HARRY!! I’m so impressed and blown away by all this research. Good god now I want to do it!

    Hi David,
    Came across your biog on NextDoor. Fields corner area here. Have you look at Tivoli Audio ART speakers? They don’t need to be hard-wired into the house, can be battery operated for portability, and are considerably cheaper than Sono. Plus, they come in a few different models to fit the decor of each room you put them in. http://www.tivoliaudio.com
    best,
    Jed

      Thanks for the comment Jed. Just looked into these and they are beautiful. Really neat. Not sure if you saw the Apple announcement at WWDC but looks like their speaker is going to do something very similarly. Overall the price point for both of those options is still a bit high.
