If you would like to extend your home stereo system out to your backyard patio or pool area, you will likely need waterproof speakers. Most indoor speakers have paper or cardboard cones that are easily damaged by moisture so an outdoor speaker will definitely need to be waterproof. Marine speakers like these are designed for boats and they come in a variety of shapes and sizes. Since they can withstand rain and splashing in a boat they make a great choice for outside your home.
One issue that many are concerned with is the fact that most home stereo systems are 8 ohms while most mobile systems, such as those found on a boat are 4 ohms. Ohms represents the resistance in the circuit. Generally the lower the ohms the more power will flow through the system.
Fortunately, 8 ohm and 4 ohm components are virtually interchangeable in most systems with little or no chance for damage to the equipment. The only real concern is that an 8 ohm system will produce slightly less volume than a 4 ohm system. But most people can’t even tell the difference. My advice is to not worry about the ohm difference between mobile and home systems.
An equalizer, or EQ, is a stereo component that controls the frequency response of your music. Frequencies are divided up into bands, or frequency ranges and each band is controlled by a slider on the EQ. Generally, the higher the number of bands, the better quality the equalizer is. A graphic EQ usually has some type of graphic representation of the frequency levels for each band as the music plays.
The idea is that every room has different a different type of resonance, so a graphic EQ can be used to shape the frequency response of the music. That sounds like a great idea. The problem? The more control you have, the easier it is to mess up your sound!
For instance, everyone likes thumping bass response so the temptation is to crank up the very low frequency bands. Well, the 50 hz band or the 60 hz band really only control frequencies that are so low they are barely audible to the human ear. Basically those frequencies sound like a low rumble. Cranking those bands up can actually make your mix sound muddy. The thump or punch to a music mix is actually at about 100 hz. Try leaving the entire line of bands flat, but then slide 100 hz up a ways. You will hear the difference immediately.
A home stereo setup can be a collection of many types of components. A classic turntable for vinyl records (yes, people used to actually listen to vinyl!) can provide a signal for a modern digital amplifier. Likewise a classic stereo AM/FM receiver can power sleek modern speakers.
There are still quite a few purists who prefer to listen to their favorite classic music on vinyl. They say the sound is different. Unfortunately, every time you listen to a vinyl record the sound degrades slightly. The needle actually does a tiny amount of damage to the record. So they are correct when they say the sound is different. The fact is, a vinyl record will sound different every single time you listen to it and not necessarily for the better!
Back in the day, a stereo system was more than a source for sound. It was a beautiful piece of furniture that adorned a room. Amazing wood finished cabinets were not uncommon. You don’t see a lot of these anymore, but it is possible to find them.
These days a modern home stereo is judged more based on what you don’t see rather than what you see. Components are usually tucked away in a utility closet and speakers are designed to blend into the ceiling and walls, matching the décor.
