Differences Between Nexo GEO S12 and GEO S8 Speakers

By | March 19, 2015

Nexo line array speakers are famous for their quality sound reinforcement, and the GEO S12 and GEO S8 lines are no different. GEO S12 and GEO S8 speakers are as efficient as the come! The elegant, ergonomic cabinets house premium drivers that output clear, coherent audio. Patented technology ensures these loudspeakers give you your money’s worth. Each line has a large accessory suite that gives you various mounting and stacking options. Nexo knocks out the competition when it comes to line array speakers!

The GEO S12 and the GEO S8 each feature two models, respectively. The S12 line features the GEO S1210 and the GEO S1230, while the S8 line features the GEO S805 and the GEO S830. There are a couple minor differences between the two lineups, which you can read in the numbers. The S12 series features 12-inch drivers, while the S8 series features eight-inch drivers. That takes care of the first half of the numbers, but what about the second half? The second half refers to the shape/degree of the speaker. So the GEO S1210 has a 12-inch driver and a 10° shape, while the GEO S830 has an eight-inch driver and a 30° shape.

The major selling point for the Nexo GEO S12 and GEO S8 line array speakers is the patented technology that comes with each speaker. Only Nexo GEO-brand speakers have this technology. There are three main features: Hyperboloid Reflective Wavesource, Configurable Directivity Device and Directivity Phase Device. These features allow GEO S12 and GEO S8 line array speakers to achieve exceptional accuracy, consistent frequency and SPL coverage, in addition to close correlation between mathematical predictions and real world results.

Hyperboloid Reflective Technology

Hyperboloid Reflective Wavesource technology ensures that various wavesources from multiple speakers work together without interference. Coherency in a line array is reached when the cabinets act as if they share a single sound source. That’s where HRW comes in. The technology controls acoustic energy with a mathematically engineered hyperboloid acoustic mirror, which creates a virtual wavesource outside the cabinet. The paths from the virtual source and real source to the horn are identical, meaning that they phase together perfectly at their coupling points.

Configurable Directivity Device

All Nexo GEO S12 and GEO S8 speakers come with Configurable Directivity Device flanges, which are nearly essential in permanent installations. CDD flanges give you a wide range of control over wavesource behavior. The flanges help you fill in any coverage gaps in your line array system. They’re also useful when you need 120° of horizontal coverage in a vertical line array compared to 80°. If you’re using horizontal line arrays, the CDD flanges can widen vertical coverage from 80° to 120°. Now you have even audio coverage washing over your audience!

Directivity Phase Device

Interference between individual speakers in line array setups is due to the physical diameters of the cone drivers. Close coupling of wavesources at the correct frequencies is necessary to crossover with HF drivers. How do you fix this? You don’t have to, because the Nexo-patented Directivity Phase Device takes care of this. DPD causes a 12-inch driver to act like dual six-inch drivers, or an eight-inch driver to act like dual four-inch drivers. This extends the upper frequency limit for line source coupling between adjacent drivers.
