The Proficient Audio C1075s is their best LCR In-Ceiling speaker even though at first glance it appears priced on the high side. However, when one is chasing significantly superior performance from an In-Ceiling speaker, then the price is soon forgotten!


I think it's fair to say that In-Ceiling speakers have helped keep the peace in many a domestic household! Let us assure you though that they have developed to a point where models like the C1075s will easily out-perform most other On-Wall, In-Wall or Satellite designs. So don't think they are inferior in any way. In fact in a Media Room - a multi-purpose room with doors and windows in difficult locations - In-Ceiling speakers may be the only choice in a Surround Sound speaker installation! And this is really what the Proficient C1075s is all about.

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

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 superior In-Ceiling performance with any of the Proficient Signature Series that are truly at the pinnacle when it comes to this category. The C1075's are suitable as for any in-door application - front and rears for surround systems including seven or nine channel applications and of course in any 'serious' multi-room music systems.

The one thing buyers need to understand is the power input. The maximum clean or undistorted input on the C1075s is an incredible and very high 200 Watts RMS! Based on that specification, it would be easy to conclude that a C1075s can handle anything. Like ALL speakers, they have limitations. If you intend to play 'em very loud, then you will need a very powerful amplifier or receiver and most likely a receiver AND a suitable power amplifier for a surround sound application. 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 if you're thinking a couple of decent subwoofers will help then you're absolutely right! To discuss this more, please speak with Simon Lee.
