Several brands design their speakers to be . It is meant to be both a summary of today's knowledge after extensive literature research and a best practice guide for similar projects such as rehearsal or recording rooms. When you play a musical note having the same pitch as the natural resonance of the room, that note will sound louder and have a longer reverb time than other notes. According to the "Bonello-criteria" this function should be strictly increasing to reach a good distribution of modes. Although PS Audio makes a phono-stage, the company does not make a turntable, so analog-lovers can't have an all-PS system. The original PS Audio Sprout, which I reviewed in the May 2015 issue, showed newcomers an easier, smaller way to amplify music recordings in the home. Richard Henry Bolt created this diagram to indicate an accumulation of good room ratios. 1 x 1.60 x 2.33. The first ten modes for each room dimension are displayed graphically so you can see where they occur and how they relate to one another. An error occurred. As said above, it's all in the setup and equalization. Note: This reflectivity graph is based on a few assumptions 1) that the room in question is currently empty 2) that its covered in drywall and has a standard-pile carpeting and 3) that the room size is reasonable and not some outlandish concert hall or tiny closet. Subsequent modes are multiples of that result. The worst type of room shape is a perfect cube - say, ten feet long, ten feet wide, and ten feet high - because all three dimensions are the same and all three dimensions resonate at the same frequency. However, those in the know know that the aspen isn't PS Audio's Paul McGowan's first foray into speaker design and sales. It is on kind loan from a member.
