NXFMR4CH vs NXLI1500-0-US — Compare
Crown XFMR-4 Four Channel Transformer vs Crown Audio XLi 1500 Two-channel 450W Power Amplifier
The Crown XFMR-4 is a passive impedance-matching transformer that converts standard amplifier outputs to 70V/100V constant-voltage systems for distributed speaker networks, while the XLi 1500 is an active two-channel power amplifier delivering 450W per channel for direct speaker drive. Choose the XFMR-4 if you need to integrate existing amplifiers into constant-voltage installations; choose the XLi 1500 if you need standalone amplification for live sound, worship, or venue applications.
No sales tax on orders shipped outside California — total cost beats national retailers that charge sales tax in nearly every state.

Frequently asked questions
What is the main difference in application between these two products?
The XFMR-4 is a transformer that converts standard amplifier signals to 70V/100V constant-voltage outputs for distributed speaker networks in large spaces. The XLi 1500 is a standalone power amplifier that drives speakers directly at standard impedances (4 or 8 ohms) and does not support constant-voltage output.
Can the XLi 1500 be used with the XFMR-4?
Yes. The XLi 1500 could be connected to the XFMR-4's inputs to amplify signals before they are transformed to 70V/100V output, creating an integrated system for distributed speaker installations.
Which product is better for a small worship space with multiple ceiling speakers?
The XFMR-4 paired with an existing or new amplifier would be ideal for distributing power across multiple ceiling speakers using constant-voltage wiring, minimizing wire gauge requirements. The XLi 1500 alone would work only if speakers are located close enough for standard impedance connection.
What does each product cost relative to the other?
Both products are in the mid price tier. The XFMR-4 is a specialized passive component, while the XLi 1500 is a full-featured active amplifier, so pricing and value depend on whether you need amplification, impedance matching, or both.
