It's not something you can invest in if you aren't ready to make it an all out effort. A home theater system, can start off small and if you really get excited about the technology, it can expand. I've seen a whole wall made up of these systems, in a home. It would come fully equipped with all the different technical setups made to enhance the system.
I live in the Dallas area and I found that there are several companies, who design, sell, and setup these systems. They will come to your home or office and give you an estimate based on what you are interested in accomplishing. Contacting a Dallas Home Theater company is something you will want to investigate for quality purposes.
I know that there are also these home theater companies listed in the phone directories. There are some in the Houston, TX area as well. If your living in Houston, then it's natural that you would contact a Houston Home Theater dealer to purchase your system. These companies are ready with the best equipment available, depending on the brand you are interested in. The offer plenty of different brands and qualified to give you the best service for your price. For more information, contact one of these dealers.
