Description

In designing LD Series speaker to attain absolute flat frequency response is the prime concern for POPE Professional® engineers. Over powering high frequency that causes hearing fatigue is reduced since we now focus on making the LD system musical and yet producing very good vocal mid range frequency and extended low base frequencies. The LD Series also offers very high quality cabinet construction and contemporary design and styling together with integrated flying point, new grille design and a very durable external paint finish.

LD Series HF component features a 90° x 90° dispersion horn couple together with our latest compression driver design. The diaphragm made of titanium utilizes KSV flat wire coil to eliminate distortion and also provides better heat dissipation and hence lowering the effects of power compression. This design give better compliancy and also bring forth better power handling and reliability. All LD speakers are tested to AES standard to provide both contractors and users with a quality of assurance.

Deviating form the norm of speaker design, POPE Professional® engineers looked at the effects of power versus linearity especially on the MF-HF section. Besides individual speaker component design, we have also look at individual electronic components on the internal passive crossover network. With careful selection and design, the LD series yield very impressive results: from 1 kHz to 18 kHz, the astonishing result under LMS testing showed the linearity to be less than 1dB deviation.

Applications

This series speakers and sub-woofer can use in the places of worship, theatre, auditorium, performing arts halls, live programs, multi-function rooms, clubs and DISCOS.
