How to choose the best passive subwoofers
Power Handling
At this price point, expect around 500-800 watts peak. It's not a ton, so don't expect it to shake a stadium, but it's enough for smaller venues and rehearsals. Clipping is your enemy - watch your levels!
Frequency Response
Ideally, you want something that extends down to at least 40Hz to get that real low-end rumble. Anything higher and your bass lines will sound thin and anemic. Don't expect sub-40Hz response without serious power.
Driver Size
10-inch and 12-inch are the common sizes. 12-inch generally delivers more low-frequency extension, but a well-designed 10-inch can still pack a punch. It's about the driver quality, not just the size.
Construction Quality
Let's be honest, you're not getting rock-solid construction. Check for sturdy bracing and a decent-feeling enclosure. Rattling cabinets kill the low-end clarity - you'll hear it, the audience will hear it.
Efficiency (Sensitivity)
Measured in dB, this tells you how loud the sub will be with a given amount of power. Higher sensitivity means you can get more volume with less amplifier power, which is a bonus for budget setups. Lower sensitivity means you'll need more juice.
Buying guide
So, you need some low-end rumble but your budget's tighter than a Les Paul neck? Been there. Getting a decent passive sub for under $300 is doable, but it's a reality check - you're not getting a massive, studio-grade powerhouse. We'll look at some options that give you the most thump for your dollar, and what compromises you're making to get there. Let's keep that kick drum felt, not just heard.
At this price, you're making trade-offs. Don't expect deep, sustained low-end like you'd find on a $1000 sub. The cabinets are often MDF, not Baltic birch, so be careful handling them.
Focus on finding a sub with a decent frequency response and enough power to handle your amp - headroom is more important than raw volume. Don't skimp on the amp either - a weak amp will just make the sub sound muddy.

Questions
Can I use this sub for recording?
Sure, but be mindful of its limitations. It'll add some low-end weight, but it won't have the clarity or headroom of a studio-grade sub. Keep the levels low and be prepared to EQ out some muddiness.
What kind of amplifier do I need?
You'll need a power amplifier that matches the sub's impedance (usually 8 ohms) and provides enough wattage. A 300-500 watt amp is a good starting point, but more headroom is always welcome.
Will this rattle my stage?
Probably, especially at higher volumes. A good stage is crucial for minimizing unwanted vibrations. Consider using isolation pads or risers to decouple the sub from the floor.
Is a powered sub better?
Powered subs offer convenience and integrated amplification, but at this price, you're often getting a less powerful amp than you could buy separately. Passive subs give you more flexibility to choose your own amp.
What's the deal with phase switches?
Phase switches are important when using multiple subs to avoid cancellations. Experiment with the switch to find the setting that gives you the fullest, most even bass response. A little trial and error goes a long way.
