holding down the sonic fort .
• They can assist in bringing the musical experience to those with hearing impairments .
• For younger generations , quality LF is an absolute must and meeting expectations holds great value , especially around retention .
• LF moves people both literally and figuratively . This new energy can help a congregation grow through connection and emotion . Studies have shown low frequencies can excite vibrotactile and vestibular pathways , along with auditory pathways , sparking spontaneous movement – enter the groove , the boogie , the fun !
• A great subwoofer will reveal layers of sound and add warmth and depth . Adding subwoofers will absolutely transform a thin ‘ one-dimensional ’ sound system into an enveloping experience that every worship band and audience member will appreciate .
THE TECHNICAL BENEFITS OF USING DEDICATED SUBWOOFERS :
• This crucial element focuses on delivering lower frequencies between 20Hz – 100Hz and creates more compelling dynamics by handling the part of the spectrum that full range speakers are ineffective at or simply not capable of delivering .
• A dedicated subwoofer will yield a linear output down to 30Hz or below , where the bass is more ‘ felt ’ than heard — and it elevates the experience in a uniquely palpable way .
• Deploying a subwoofer will reduce the low frequency workload imposed on the mains , subsequently improving the response and fidelity of the entire system . Conversely , driving a full range main to produce exciting low frequency energy usually comes with one or more associated costs :
• Overdriven mids and highs which often results in distortion , audience discomfort , and possibly even hearing damage .
• Compressed sound .
• Reduced transducer life .
HOW FOR HOW – PLACEMENT Outlined below are some of the most common House of Worship subwoofer deployment locations , along with their pros and cons :
Under Stage Pros :
• Even side-to-side coverage .
• Easy to service and relocate .
Cons :
• Stage height limitations .
• SPLs can differ dramatically front-to-rear .
• Stage coupling = resonance and feedback in non-bunker environments .
Solutions :
• Companies ( such as BASSBOSS !) offer dual 15 ” active solutions with a very low height profile . Seek out these solutions .
• Consider cardioid configurations .
Center Stage - Front Pros :
• Even side-to-side coverage .
• Usually fairly easy to access and service .
Cons :
• Less than ideal aesthetics .
• Consumes real estate and can be obtrusive .
• SPLs can differ dramatically front-to-rear .
• Resonance , feedback , and SPLs on stage will need to be kept in check .
Solutions :
• Consider cardioid configurations .
Flown Pros :
• Most even coverage of the room , side-toside and front-to-back .
• SPL deviation can be reduced 50 % to 60 % in many cases .
• Stage decoupling and reduced stage feedback .
• Preserves valuable floor space .
Cons :
• Generally , the ceiling will not serve to provide a boundary boost . SPL losses
