Things To Consider When Buying RCF 905 AS II
Design
The first thing to consider when choosing a subwoofer is design. Specifically, the type of enclosure. There are 3 types of enclosures, sealed, ported, and bandpass. The two most common subwoofers are sealed and ported.
Sealed enclosures have an air-tight seal on all sides so all of the air insides are compressed when the woofer fires. This causes a more accurate sound but it doesn’t give the woofer much room to move. This is why they usually have higher power handling because they are very rigid.
The second type of enclosure, ported, has a “port” on one side of it to allow air in and out of it instead of being compressed. It creates more movement in the woofer which results in louder low frequencies but can cause inaccurate sounds.
Bandpass enclosures are the least popular type of enclosure because it combines both ported and sealed together to create what is referred to as infinite baffle. All three types of enclosures have their advantages and disadvantages so it really just depends on what you prefer hearing.
Power Handling
Another very important thing to consider when buying a subwoofer is power handling. This spec determines how much power the woofer can handle before it breaks or malfunctions. Power handling of a speaker, like most specs of a speaker, is measured in watts.
In order to get the most out of your subwoofer, it’s recommended that you have anywhere from 1-2x the wattage as the high end of the power handling. For example, if you have a 500w sub you will want to make sure you have at least a 1000w, or more, amp.
This is to make sure the power going into the woofer is strong enough for it to handle and keep up with a clean sound. If you don’t have enough wattage going to your subwoofer you could damage the voice coil in it which will make it not work anymore.
Size
There’s not too much to say about the size that hasn’t already been said. You should, of course, measure your subwoofer to see how big it is before you buy anything. If you try to cram a 12″ sub into an enclosure for an 8″ sub you could end up with some problems like poor sound or maybe even not fitting at all.
This wouldn’t happen with every sub, but it’s definitely possible. Not all subwoofers are created equal, some are bigger than others, even if they have the same specs. If you don’t know how big your sub might be make sure to measure before buying anything. It will save you time and money in the long run!
Impedance
Impedance, or ohms, is another important spec that you should consider before buying a subwoofer. It tells you how much power the speaker needs to operate properly. There are two different kinds of resistance measured in ohms, impedance, and resistance.
The wattage mentioned above is usually not enough for you to know what kind of ohm your subwoofer needs unless you get the exact number from the manufacturer. Even then it’s hard to say if they’re lying or not without testing yourself.
It’s a good idea to have an amp with the same ohm as your subwoofer so there isn’t a lot of resistance on it. This is important because if you have too much resistance, besides just being obnoxious for no reason, it can damage the amplifier since amps usually have heat protection that turns them off when they get too hot.
Frequency Response
This is another spec that tells you what kind of range the subwoofer can handle. It’s usually measured in Hz and is how low or high something can go, literally. When you see frequency response on a subwoofer it’s telling you the highest frequency the speaker goes up to. This number will sound very high if your hearing isn’t very good. Like anything, this number is a range and not a specific number.
Usually, the lower this number is, the better it will sound but that’s not always true. There are cheaper subwoofers than others that don’t have the best frequency response but sound much better than their price would imply because of other factors like power handling and size.
It’s important to know how low your subwoofer can go before you get one because if the lowest it can go is not very low, like under 50Hz, then your system won’t sound good regardless of what other factors are involved. For home theater systems where you want more than just bass for watching movies or playing videos.
