Beta Three

The RS15 is great for a monitoring speaker, I haven used this in a several different occasions over the last 3 years. It is amazing if used for voice and speech as well as using it for live music. If using the Betta Three RS 15 indoors you will need to make sure the indoor facility you are using it in is not to big, or too small as it can effect the sound. I love the way the Rs15 sounds in an outdoor setting, it seems like the open space just lets the speaker expand especially when playing music. The Rs15 has a plastic speaker with coaxial horn, it is perfectly design for maximum sound expansion and play back. The look of the Rs15 is very nice, it has a very nice sleek style and looks a lot different than most of the other models of speakers and PA systems that came out that same year that this one did. When purchasing this it is best to get the stand with it, because putting this on a ground level wont let the sound carry as well, you will want to have up of the ground and facing toward your listeners or the crowd (which ever you are using the speaker for). The RS 15 sounded very similar to me to the Ra8’s and the Ra10’s. There difference in these monitors is so minimal it seems that the only difference is the price tag that’s tied to each one of them. The Rs15 peaks out at 1600W, and the total weight of it is around 29kg. It can be moved from place to place easy if you have some help. You could carry it yourself but you would have to be pretty strong, so don’t plan on being able to easily move it from your truck to the play site. The crossover point on the RS 15 is 2kHz with a frequency response of 45Hz - 20kHz. We love using the RS 15 every chance we get to use it, if I owned a club or something I would have purchased this back in 2008. Other models to look into if you like this one are the Ra8’s and the Ra 10’s as they are very similar to this one.

R4/R8 is specially designed for luxury cinema, large-sized meeting room, multi-functional hall, church and auditorium applications. The system consists of 1 active subwoofer and 4 full range speakers which can form multi-cluster configurations. R8/R4 is designed by applying the line array concept. It features compact dimensions and an easy to handle design. The built-in 600W amplifier and DSP make it available for use at any moment when connected to sound resource. System control over each cluster at frequency response, crossover point & slope, delay, gain and limit protection can be achieved by connecting the speaker system to PC via USB or RS232 port. Adoption of ribbon tweeters offers a wide-range frequency response to up to 40KHz. The tweeter's impedance and phase response curves are nearly ideal horizontal lines. The light moving mass of milligrams ensures excellent impulse response. Utilization of the unique thin foam surround and specially coated cone paper has reduced the distortion rate effectively. The active subwoofer applies Low Distortion, Linear Amplification, and DSP technologies. Input signals are amplified by the built-in pre-amplifier, then processed and distributed by DSP, finally output via power amplifier to the subwoofer and the full-range speakers, which forms an integrated system. The flying hardware is designed to fit different application situation flexibly with the splay angel adjustable by 1° increment vertically.

(Originally written by nrgtik29/translated from Audiofanzine FR) - How long have you been using it? 1 Year. - Which feature do you like the most / the least? High efficiency considering the loudspeaker type. Very good manufacturing quality. - Did you try any other models before buying it? I tested many loudspeakers but they were too expensive for my budget. - How would you rate its value for money? GREAT! High efficiency for a super low price. The finish is superb and the sound very nice. They are the perfect low-budget loudspeakers. - Based on your experience, would you buy this product again? Definitely not if I had more money. And yes if I only had the same budget. In this price range, you won't easily find other full-range loudspeakers with this efficiency and this manufacturing quality.
