AC115S-WH vs CBT-70J-1-WH — Compare
JBL AC115S-WH 15" Subwoofer, white vs JBL Cbt 70J-1-WH J-shaped 2-WAY Line Array Column Spk, Wht
The AC115S-WH is a dedicated subwoofer focused purely on deep low-end reinforcement (32–250 Hz), while the CBT 70J-1-WH is a full-range line array column speaker handling the entire frequency spectrum (60 Hz–20 kHz). Choose the subwoofer if you need tight, controlled bass punch for PA or installed systems; choose the column speaker if you need a self-contained, full-frequency solution for venues where compact mounting and articulate mids/highs matter.

Frequently asked questions
Can these products work together?
Yes. The AC115S-WH can serve as a dedicated subwoofer paired with the CBT 70J-1-WH to extend bass below 60 Hz in venues requiring deeper low-end. However, the CBT 70J-1 operates independently and does not require a sub.
Which is better for houses of worship?
The CBT 70J-1-WH is purpose-built for houses of worship with its focused J-shaped projection, minimal spillover, and wall-mount integration. The AC115S-WH alone would only provide bass and is not suitable without accompanying full-range speakers.
What's the key frequency difference?
The AC115S-WH covers 32–250 Hz (bass only), while the CBT 70J-1-WH spans 60 Hz–20 kHz (full range). The column speaker reaches higher frequencies for mids and articulate highs; the subwoofer goes much deeper for subsonic reinforcement.
Which is easier to rig and transport?
The CBT 70J-1-WH at 21 lbs with integrated fly points is significantly lighter and more transport-friendly for single-person rigging. The AC115S-WH is heavier and designed for permanent or semi-permanent installed applications, though it includes 12 M10 suspension points for rigging.
