Quick answers about the LBC3484/00, and how it compares.
Which speaker for a masjid?
A masjid needs three kinds of coverage.
Prayer hall: wall-mounted cabinet speakers such as LB2-UC15-L1 / LB2-UC30-L1 or LB1-UM20E-L, or column speakers such as LA1-UM20E-1 / LA1-UM40E-1, LA1-UW36-L1 or the LBC3200/00 line array. They carry speech the length of a hall with hard walls and keep it clear; ceiling speakers in a high hall do not. For a premium sound use Electro-Voice EVID surface speakers (EVID-S5.2TB, EVID-S8.2TB); for a high-end hall with long reverberation, the Electro-Voice LRC column speakers (LRC-1060-B, LRC-1100-B, LRC-2100-B), supplied on request.
Low-ceiling rooms, ablution areas, corridors and offices: ceiling speakers (LC1, LC3, LCM, LHM ranges).
Minaret and courtyard: horn speakers LBC3482/00, LBC3483/00, LBC3484/00 or LBC3481/12, LH3-UC25XL for very long throw, or the LBC3474/00 50 W driver on an LBC3479/00 20" flare for the minaret.
Coverage depends on the acoustic characteristics of the hall (size, height, hard or soft surfaces, reverberation), so the best suggestion comes from ESCO's Bosch and Electro-Voice certified engineers: take the free pre-sales consultation and they will size the amplifier and the number of speakers for your masjid.
