About Proficient Audio C606 In-Ceilings

The Proficient Audio C606 speaker installs flush in your ceiling. It's a great speaker for multi-room audio systems. Install a pair or two of these compact speakers in a hallway or mud room, and use multiple pairs in a kitchen for well-balanced sound throughout the room.

You'll be amazed when you hear how much sound Proficient's most affordable 165mm (6½") ceiling speaker puts out. Its sturdy polypropylene woofer is the same type found in many high-quality bookshelf speakers. And its 19mm (¾") soft-dome tweeter sounds surprisingly sweet - no surprise when you learn it was engineered by the same team that designed their top in-wall, on-wall and bookshelf speakers. The C606's 90dB sensitivity delivers relatively high output even with lower-powered multiroom audio amplifiers. The sensitivity specification is right in the middle of what is considered an acceptable figure. The higher the number, the easier it is for the amplifier and the opposite is true when the number is lower. The C606's forgiving 8 ohm impedance also makes them easy to drive with most amplifiers. It also fits into the same cutout as Proficient's other 165mm (6½") ceiling speakers do, so it's easy to install or upgrade to something even better down the track. 

Research - Building Projects

If you are reading this material as part of research of a new building product, then you may be surprised to know that on average in the USA, 65% of all new homes built have multi-room sound in some description specified as a standard feature. Although we don't have the exact figures for Australia, we're fairly confident that it will be the same or even more. Australian's love new technology.

But sadly, the big home builders have looked at this as a simply a profit opportunity and unless you organise otherwise will install what are known as "contractor series" speakers. If you guessed that these were bottom of the pile quality, you'd be right! A wrong decision here means you are stuck with bad sound and until the day you move or have them replaced.

Tip: Due to a simple lack of knowledge, many consumers think that In-Ceiling Speakers are a cheap option/alternative to other types of speakers. However, good quality In-Ceiling Speakers need some serious engineering to work well in your ceiling where dust and extremes of temperature take their toll. Some models - including Proficient Audio - have 'boxes' that you can buy as an optional extra which protect not just from the elements but are also meet one-hour fire-proof specifications.

Our Take On The C606

For those of us that have not only a need for in-ceiling speakers, but a desire for something that has been designed to sound as good as possible, Proficient Audio based in the USA and part of the Nortel Group is a company you can trust. They are also the company behind Elan and Niles whom we also support and have done for around 25 years! Looking at the improvements they've made in the different lines over the years, shows clearly that they are thinking about the specific use of the speaker in the home environment. You'll enjoy very good In-Ceiling performance with any of the Proficient Audio range at any given price. The C606's are suitable as for any standard in-door application - rears for 5.1 surround systems and of course in any entry-level multi-room music system. 

The one thing buyers need to understand is the power input. The maximum clean or undistorted input on the C606s is 75 Watts RMS. Like ALL speakers, they have limitations. Why? The reason is that it is distortion that 'cooks' or destroys a speaker so you need an amplifier AND speaker system that will deliver the volume level you want - even for very short periods - without any distortion and this is why we suggest you use these in lower level multi-room music systems. And if you're thinking of one or even two subwoofers will help then you're absolutely right! To discuss this more, please speak with Simon Lee or send an email to: [email protected]
