There are plenty of technical innovations in the Silver 500 7G. Rigid Surface Technology II that keeps the sound perfectly clear and controlled even at high volume. A crossover system that balances output from the tweeter and bass driver as needed. A consistent and smooth frequency response that sounds great with all genres of music. We could go on, but you only really need to hear one thing: the first note of your favourite song played on a pair of Silver 500 7G Speakers. Then youÕll understand why itÕs everything the hardened audiophile could want, and everything the casual listener could need.
