A true subwoofer will be able to reproduce a 20 Hz test tone, which will be rather felt than heard, but 30 Hz will do very well in most listening environments and for most music. Most subwoofers today contain a built-in amplifier and a crossover network that allows you to adjust the sub's upper frequency response so as to more effectively blend in with your main speakers. Subwoofer performance is greatly affected by placement. So where you place the subwoofer and where you sit are critical to getting the most from it. https://enrock.com/knowledge-base/post/subwoofers-guide Wed, 22 Jul 2015 05:18 -0800 https://enrock.com/knowledge-base/post/subwoofers-guide The marine speaker market offers several types and styles of units, each of which have their own uniqueness and niches. your choice will depend on the size you'd like to see covered, the ambient noise-level of the environment, and whether the speaker will be sounding off foreground or background music. If you are replacing an existing pair of speakers, there would already be a cut-out hole which will considerably narrow down your search. If you will be cutting a new hole for new flush mount speakers, you'll want to first measure the area. When considering the space, remember to measure the depth of space behind the speaker as well, since there needs to be enclosed air space behind and around the speaker. Also, since larger speakers typically tend to give better sound, it would be wise to find the largest space possible. https://enrock.com/knowledge-base/post/speaker-categories-guide Wed, 22 Jul 2015 05:15 -0800 https://enrock.com/knowledge-base/post/speaker-categories-guide Very High Frequency (VHF) radios serve as the primary means of communication for boats, yachts, and vessels. As the name says it, these devices are intended for communication between yourself on the water and the rest of the world. Specifically, the uses for VHS radios generally fall into one of the following: Distress calling and safety Ship-to-shore communications Navigation (vessels to bridges, and the like) Marine operator to place calls to shore NOAA Weather Broadcasts https://enrock.com/knowledge-base/post/satellite-and-vhf-radio-guide Wed, 22 Jul 2015 05:06 -0800 https://enrock.com/knowledge-base/post/satellite-and-vhf-radio-guide You've done some happy shopping and spotted that perfect after-market stereo to rock your boat and enrich your voyage. Great! Now it's time to get that gear in it's proper place. The first step of the installation process is removing your current stereo (duh). One of the things to keep in mind is that there are several types of marine stereos, with each of them being installed -- and therefore removed -- differently. https://enrock.com/knowledge-base/post/removing-your-old-stereo Wed, 22 Jul 2015 04:58 -0800 https://enrock.com/knowledge-base/post/removing-your-old-stereo There are many navigational tools and means available for boaters. The marine radar is arguably one of the more difficult ones, not only because those radars tend to be more costly than their cousins, but also because operating and reading them aren't quite a breeze for the untrained. Let's have a closer look at those devices. On a fundamental level, marine radars function similarly to echo sounders, which is, transmitting an energy pulse and then measuring the time it took for the pulse to bounce back. The main difference between the two lies in the means; while echo sounders utilize ultrasonic sound, marine radars do their magic using microwaves. The main device measures the time it took for the waves to return, and calculates distances based on that. https://enrock.com/knowledge-base/post/radar-guide Wed, 22 Jul 2015 04:53 -0800 https://enrock.com/knowledge-base/post/radar-guide We know boats and we're intimately familiar with sound. It isn't just the vast variety of audio and video items and products we stock, but even more so we're totally into marine audio gear. Our staff is almost obsessed with music on the water and as eager to help you equip your boat with superior gear so to get you sailing to crisp sound. https://enrock.com/knowledge-base/post/quick-guide-to-marine-audio Wed, 22 Jul 2015 04:51 -0800 https://enrock.com/knowledge-base/post/quick-guide-to-marine-audio Here’s the deal with marine audio systems: we want them to rock the boat, but at the same time to know how to survive the rough marine life. As much fun those boats provide us with, the audio systems have it real hard. With constant exposure to glaring sunlight, hard rain, and extreme temperatures, a marine audio system has to stomach a lot of abuse. If you want soothing sound on your boat, you’ll need marine gear designed to stand up to the task. Unlike car audio components, which are suitable and comfortably parked in the interior of your automobile, marine equipment has to be able to take a lot and hold up under dire circumstances. The water and sun that make boating for such a blast have no problem wreaking havoc on your boat's electrical apparatuses. If your equipment isn't made for the tough marine life, it won't last the season. https://enrock.com/knowledge-base/post/marine-stereo Wed, 22 Jul 2015 04:48 -0800 https://enrock.com/knowledge-base/post/marine-stereo As much fun those boats provide us with, the audio systems have it real hard.

Unlike roads and paths, the water is a vast and open place, where finding your way entails creativity and knowledge. For centuries, we've been relying on star charts, compasses, and latitude and longitude numbers to navigate the seas and waterways. These techniques have constantly been refined and updated, but the main premise has remained intact. All of this has changed in the most revolutionary way when the GPS technology has entered the scene. Sailors were now able to pinpoint their location with astounding accuracy, and figure out their way through the waters with unparalleled efficiency. https://enrock.com/knowledge-base/post/gps-navigation-guide Wed, 22 Jul 2015 04:43 -0800 https://enrock.com/knowledge-base/post/gps-navigation-guide
