Frequently asked questions
Can I use the 3730-M/HF as a standalone speaker?
No. The 3730-M/HF is the mid-high section only; you must purchase the separate 3739 dual-15 bass cabinet to form a complete system. It is not designed for standalone use.
Which speaker is better for a church or live venue?
The CBT 70J-1 is ideal for churches and live venues because it is a complete, self-contained 2-way speaker with switchable vertical coverage patterns. The 3730-M/HF requires professional system integration and is engineered specifically for cinema installations.
What is the power-handling difference?
The 3730-M/HF handles 125 W (AES 2-hour rating) at 4 ohms, while the CBT 70J-1 handles 350 W RMS at 8 ohms. The CBT 70J-1 is rated for higher continuous power and has broader amplifier compatibility.
How do the frequency responses compare?
The 3730-M/HF is only the mid-high section (crossing at 450 Hz and 2 kHz with a bass cabinet); it cannot reproduce low frequencies alone. The CBT 70J-1 is a full 2-way system with sixteen tweeters and four 125 mm woofers, delivering complete frequency coverage without additional components.
