As is the way with ProAc, it’s going to be rather hard to get excited about the D40/R speakers based on their looks and specification. But as we learned with the D18s on web page 64, the fairly small British manufacturer is capable of producing extraordinary sound from instead ordinary-looking boxes.
Take a closer look at the D40/Rs and there are a number of details that might hint at something a lot more than ordinary. There’s a ribbon tweeter in the first place – a 6 x 1cm unit that provides the presenter the R’ in its name. You can buy a standard D40 with a conventional soft-dome tweeter for approximately 250 less compared to the D40/R, but in our minds the ribbon is worth the extra – more on that later.
Wide choice of finishes
And while we’re discussing optional extras, bear in mind that our review sample is modelling a rosewood veneer, which stretches the price right up to 7350. It’s lovely, no doubt, but we’ve also seen the standard cherry, maple, mahogany and black ash finishes, and they’re also exemplary.
Why do we need an air purifier?
An air purifier is an electronic device which removes various types of impurities from the air in a room. Air purifiers are of utmost importance in areas affected largely by air pollution or in areas where there is a lot of dust to deal with. If you have ever longed for better air for breathing which has least or almost no pollution, then an air purifier can become your best friend for the job. It not only cleans the air containing allergens or pollutants but also kills any bad smell in the room. Such is the utility of the device. Though there are a number of good air purifiers available, ranging from small to large and power-efficient to clean-efficient, you need to be well aware of the features before investing your money.
