Picking The Ideal Home Theater Speakers - By: Jonathan Schultz, Posted on: 2007-08-08

There are many decisions these days one has to contemplate and one of these decisions may be what to get for an HT system. Many brands exist in the real world and each brand offers something different than the others with a different philosophy and overall theory of sound. While we respect these other brands, how does one come to the conclusion to choose one over the other, especially if you have never physically heard the brand(s) you're pondering? We'll offer some inside non-bias advice on where to begin, what to look for and when to run.

The first objective is to start with a decent home theater receiver or going with separates that'll enable a better sound quality that may fit your liking. Receivers are a one-stop shop, while separates consist of 2 units that require more than one shelf in your rack and often cost more than a receiver. With separates, one piece of equipment does the processing capabilities, while the other does the amplification.

The next step is to choose speakers. Before going into the different types of speakers, it really does help to keep all the speakers the same brand and same series with the same type of driver material to obtain the very best timbre match. Without a proper timbre match, you'll hear that bus explode, but will leave you guessing as to which direction it came from. In other words, you'll want birds of a common feather.

Generally, if you're looking at acquiring a system to use for both movies and music, you're going to want to purchase a set of tower speakers that will allow for sufficient bass during 2-channel as well as provide the needed fullness for explosions in movies. The laws of physics state that the more drivers you have and the larger these drivers are, the greater the potential you now have to obtain the full frequency response. This is crucial in terms of enabling the 'perfect sound' to encapsulate you.

Once you've chosen your front mains and wish to incorporate them into a HT setting, the next speaker that's often been depicted as the most important is the center channel. About 60% of the information in a movie (depending on the type) comes through this speaker. Back to the basics of physics; the larger the center channel speaker, the fuller vocals will be in any movie. A large center is crucial, as you won't find yourself playing with the center volume during quiet passages in a movie.

As for rears, the information passed to this channel is generally in the midrange and treble frequency range. Also, keep in mind the recommended crossover for a movie setting format is 80 Hz, so the drivers in the rear speakers don't necessarily have to be the same size as those in your front mains. Dipole speakers are typically the most popular, however bookshelves are also a good choice. In a dipole speaker, one of the tweeter's phase is reversed to present greater distance between you and the dipole speaker. In turn, this creates a larger feel to what's going on in the movie; similar to that of a movie theater. You would want to use bookshelves in the case of using your system for either super audio (SACD) or DVD audio. SACD and DVD audio require a greater dynamic range and having drivers with proper excursion rates in a larger-sized cabinet will benefit the sound stage and imaging of your system.

The .1 in a home theater system stands for the sub. If it were .2 or a 5.2 system, there would be 2 subs helping to equalize bass response, producing an essential balance for action/adventure movies. Subwoofers come in different forms for use in several applications. A common type of subwoofer is one that has a porthole built into the cabinet, releasing the pressure. This design allows for a lower bass response as the driver has the opportunity to attain a lower frequency response. This type of subwoofer is ideal for movies, and by placing the sub into a corner of the room, explosions come to life more effectively.

A second type of subwoofer is a sealed enclosure type. This design allows the pressure to be kept internally, resulting in a tight, accurate bass response that provides time-aligned bass with upper frequencies when listening to music. Ported subs can become almost annoying, as you would receive a greater delay (as with a kick drum) than a sealed enclosure type.

The third type is the passive radiator whereby you have an active driver with at least one or more inactive drivers that work in unison with the active driver to bring you an overall lower frequency response. This design is efficient in a way where the cabinet size can be on the smaller side, but still have the ability to generate some serious bass. These type of subs work fairly well playing music with only minimal delay, but come alive in the sub-low frequency world for movies.

Speaker wire is needed to transfer the electrons from your receiver/amplifier to each channel, where by the means of electromagnetics, these electrons are transformed to audible sound waves. The thicker the speaker wire, the higher the potential for more electrons to travel to each speaker. If you're running speaker wire longer than 25 feet, it's often recommended you have speaker wire at least 12 gauge.
