Reference Studio Speakers are loudspeakers typically designed for the professional recording studio environment where accuracy in audio production and listening accuracy is critical. Musicians and record producers live and die on the quality of their music mix, which is why so many record producers and musical artists are loyal to certain recording studios and brands of reference monitors. Every quality recording studio has more than one set of reference speakers to provide options and keep their creative clients happy. In every high-end recording studio today there are a a variety of quality reference loudspeakers to choose from which include near-field monitors which have a compact or (close-field)design. Because the typcial "consumer" will listen to a music artist's recordings played back on a wide variety of sized speakers, rooms, car stereos, earbuds etc. its important to listen to a variety of sources to get the right balance of high, mid and low frequencies in the music recordings so the music will sound great no matter where or how its being listened to. The musicians also will scrutinize the sounds and tones of their voices and instruments to try to get the perfect sound they are striving for. That's why its so critical to have the best speakers possible in the recording studio.

Often musicians will record their performances with headphones on and then rush back into the studio control room to evaluate their performance using the reference monitors as their guide. Of course, there are a wide range of brands, quality, looks, performance capabilities and price points for reference monitors. As with most things in life, the higher priced brands often come with higher quality components and attention to detail. Brands such as Avalon Acoustics and Paridgim Persona reference speakers is two of the elite reference audio speaker manufacturers in the world (which HD Design Group is proud to carry). In fact, HD Design Group has a specially built audio listening room just for our clients to hear these amazingly accurate loudspeakers!

But don't forget the other components to a reference listening situation. Its not just the speakers! Its the room, how the acoustics and standing waves setup plus the other electronics, the wiring, the amps, the preamps, the media player...all these things come into play and need to be setup by experts that know how all these pieces interact. Done right...you can have a virtually perfect listening environment to experience and enjoy!
