With a wide range of Bluetooth speakers and Hi-Fi systems on the market, it is difficult to choose the best set-up to listen to your favorite tunes. So, which speaker is best for you? If your looking for a great sounding, portable speaker, your going to need one with Bluetooth capabilities so that you can connect to it with a mobile device. Or, you can get one with an audio jack and you can wire your MP3 player in directly. However, these small speakers struggle with the lower frequencies, so the best are expensive. If your looking for a permanent Hi-Fi setup, big is the way to go. The larger the cone on the speaker, the louder and more capable it is of replicating the digital sound it is given, back into its analogue form. Ultimately, you must find a niche between great sound and expenses.
