Protecting speakers in home theatre application?

I have an Adcom preamp and amp (GFP-565, GFA-535 II) driving a set of B&W Nautilus 804s. I am considering using this with a new TV via a (yet to be purchased) DAC, but I am wondering whether driving the speakers with TV / movie audio with non-music, non-voice special effects audio audio risks damage to the speakers. This includes signal drop-outs / and static-bursts since the HDTV tuner will be over the air broadcast rather than cable.

I looked for prior discussions but did not find them. Any thoughts or pointers to other discussions?

One final comment- I care most about music, not TV and movies, which I just need to hear. I’m not trying to build a theatre. So, I’m hoping to get a rather cheap DAC and maybe a cheap line-level pre-amp with a remote volume control. These components could also be a worry. To be clear, the setup would be to take the digital TV signal via toslink to a DAC; take the line level from the DAC by RCA to the in-line volume control and from there to an AUX in of the Adcom preamp. For music, my CD player goes into another input of the Adcom pre-amp and is free of all this new nonsense...just CD, Adcom pre-amp, amp, and speakers.

What I found is that home theater and high end stereo, don't do well together.   I have each of mine in a different room of the house and am very pleased.  I can max out each of their particular traits much better that way.

My hi-fi is also in a different room in "the mansion" than my TV…I've issued hover boards to all the servants by the way, so as to lesson all the pesky foot noise (highly recommended). I use an old receiver for the TV, and run a signal from the "big screen Sony" (a line from "Pretty Girls Rule the World" recorded  by David Lindley) to the receiver which is used in stereo mode (not surround as I don't care) powering my very old Boston Acoustics A60IIs (which sound great…replaced the woofers at some point)…and it does the job. A line from the DVR provides signal to my Sony wireless headphones so I can silently watch stuff after the servants and my wife go to bed (not with each other hopefully as I'd hate for the servants to not get enough sleep).

Wolfie- you crack me up, man!  But given what we now know about hover boards, I hope you've got a hold harmless clause in their contracts 😜

Thanks for your comments. I must fit everything into one room. In any case, I'm still left with the question of whether there is a risk to the speakers.

I can't speak directly about your B&W 804's but the Klipsch RF-63's I have been using since May 2008 have taken everything that I have thrown at them.  From very demanding 2-channel music to very complex and dynamic high resolution BD movie effects to TV/Netflix fed with toslink to DAC to preamp/processor.

I had an OTA HD antennae for a while with it's static bursts and dropouts and never experienced any ill effects.  If my RF-63's(msrp $2000.00) can take some abuse, I would think your 804's(msrp $7000.00) could also.

Are you more concerned with your tweeters, midrange drivers, or your bass drivers getting fried?
