Product Details

Celestion FTR15-3070C 15" Professional Cast Frame Speaker 400W

The Celestion FTR15-3070C 15" pro speaker combines high efficiency with smooth response, backed up by superb reliability. Celestion's expert engineering ensures every operating parameter has been completely optimized, which guarantees faultless performance -- even under the stressful conditions found in pro audio environments. The FTR15-3070C features an Inside/Outside voice coil that is wound on a nearly indestructible fiberglass former. Winding the coil on both sides of the former ensures the stress of thermal expansion is canceled by the opposing masses of copper wire. Accurate and durable, the FTR15-3070C will provide excellent service in direct radiator and horn-loaded applications.

Would the FTR15-3070c work best in the mid or bass compartment?

Replacing speakers in my JBL JRX125's. One cab is definately louder when I sweep from left to right. Should I have concerns over the cross over? If not, I would move one OEM spkr. over & put one Celestion spkr in ea. cab., as I'm on a budget. Would the Celestions work best in the bass or mid compartment? (The horn drivers were just replaced & sounded identical.)
Asked by: Bassman5000
Ideally, you would rebuild the entire cabinet[s]. But if you are replacing woofers, put these in the bass compartment. Inspect your cross-over componentry if you suspect one is damaged. You would need to consider changing the cross-overs only if the speaker impedance changes from 8 to 4 ohm, say.
