01 About subwoofers
About subwoofers
A subwoofer takes the low frequencies off the main speakers. That does two useful things: it adds the weight that music needs, and it lets the full-range cabinets work harder on speech and mid-range without distorting.
The SH range covers 10, 12 and 15 inch drivers in heavy-duty MDF cabinets, from 200W rated on the SH-10 up to 600W on the SH-15, all at 8 ohms. Maximum power handling reaches 1000W and sensitivity climbs to 120 dB on the largest model.

03 How to choose
How to choose subwoofers
Match the subwoofer to the room, not just the tops
Low frequencies load into a room's dimensions. A 10 inch SH-10 is right for a meeting hall or a small venue; a 12 inch SH-12 covers most mid-sized events; the 15 inch SH-15, reaching down to 25 Hz, is for large halls and outdoor events where the low end has nothing to reinforce it.
Account for the weight
These are 15 kg, 21 kg and 27 kg cabinets respectively. For a fixed installation that is irrelevant, but for a mobile rig it determines how many people are needed to load in and what transport the system needs.
Give the subwoofer its own amplifier channel
As 8 ohm passive cabinets these need a dedicated channel, ideally with a crossover so the mains are high-passed and the sub takes everything below. Running mains full-range alongside a sub wastes power and muddies the low mids.
04 Common questions
Common questions
01Do I need a subwoofer for a PA system?
For speech, paging and announcements, no — full-range speakers cover the frequencies that carry intelligibility. A subwoofer earns its place when the system also plays music: events, DJ setups, assemblies with recorded content, worship spaces with a band.
02What size subwoofer should I choose?
The 10 inch model suits smaller indoor spaces, the 12 inch covers most typical event and hall use, and the 15 inch is for large venues and outdoor work. Larger drivers reach lower and move more air, but need more amplifier power and considerably more transport.
03Can I connect a subwoofer to a 100V line system?
No. These are 8 ohm passive cabinets and must connect to a low-impedance amplifier output. A 100V line PA system and a subwoofer are answering different questions.
