Frequently Asked Questions about Powered Subwoofers

How do powered subwoofers differ from passive subwoofers?

Active subwoofers have a built-in amplifier; you just need to plug them in and connect the signal to use them. Passive subwoofers do not have an amplifier and require a separate power amplifier to drive them, making the matching process more complex. See also: Subwoofers: Uses and common types of subwoofers.

How do you choose the right powered subwoofer wattage for your room size?

Phuc Truong Audio guides you on choosing the right powered subwoofer for 3 common room sizes:

1. For rooms under 20m²: A subwoofer with a power output of 150W – 300W RMS is sufficient.
2. For rooms measuring 20m² – 30m², a subwoofer with a power output of 300W – 500W RMS is recommended.
3. Rooms larger than 30m² or open spaces: Require a subwoofer with a power output of 500W RMS or higher.

Refer: Which powered subwoofer model is suitable for 30, 40, or 50 inch speakers??

Where should a powered subwoofer be placed for the best sound quality?

The most common placement is in the corner of the room, which takes advantage of wall reflections to enhance the bass. However, you should experiment with a few different positions (next to the main speakers, next to the TV stand) and sit in your usual listening position to find the best and cleanest bass response.

What is the purpose of a "crossover" on an active subwoofer?

It's used to determine the highest frequency the subwoofer will play. For example, if you set it to 80Hz, the subwoofer will only play sounds below 80Hz, while sounds above 80Hz will be handled by the main speakers. This prevents sound overlap between the subwoofer and main speakers, creating a seamless sound experience.

Do I need two powered subwoofers?

Using two subwoofers will help distribute the bass more evenly throughout the room, minimizing "dead zones" (areas where the bass is weak or completely absent). If your budget and space allow, this is a very worthwhile upgrade.

What is the difference between a downward-facing powered subwoofer and a front-facing powered subwoofer?

Down-firing bass: The bass sound spreads across the floor before reaching the listener's ears, creating a more expansive and resonant bass sensation.

Front-firing bass: The bass is directed straight towards the listener, creating a more direct, powerful, and fast-paced bass experience.

Why is my powered subwoofer making a buzzing or rumbling sound?

This could be due to the speakers being placed too close to the corner, poor quality input sound, or too many flat surfaces in the room causing resonance. Try moving the speakers a little further away from the wall or contact Phuc Truong Audio for further advice on acoustic treatment of your listening room. Reference: Instructions for installing and adjusting standard subwoofers, good.

How do I connect a subwoofer to an amplifier that doesn't have a subwoofer output?

You can use the amplifier's Pre-out port, or use the high-level input on the subwoofer (if available) by connecting it in parallel with the amplifier's main speaker terminals. See details: Guide to connecting a subwoofer to an amplifier for quality sound..

Which subwoofer brand is best for karaoke?

Brands like JBL, Paramax, BIK, and Cavs are often tuned to deliver a powerful, tight, and punchy bass sound, making them ideal for karaoke.

Which subwoofer brand is best for watching movies and listening to music?

Brands like Yamaha, Wharfedale, Klipsch, and SVS typically excel at deep, detailed, accurate, and musically rich bass, ideal for movie viewing and audiophile experiences.
