My subs are located in opposite corners on opposite ends of the room and are not locatable. They also go lower than 20hz. And my system is very modest compared to a lot of systems of other AVS guys.
Sorry you have attended the wrong cinemas.

Note the candles ARE not even in front of the subs but beside. Your home set up has NOTHING on that.


And the payoff is never certain: Some observers contend that a generation has already been trained to be content with the small screen.

Some servers can do non-encrypted playback to an A/V projector, but it's just a ridiculously expensive media player if you don't have a cinema projector.

This doesn't even make sense. If you truly made your wall into a bass reflex cabinet, then what good does it do for the port to be into the attic, and not the listening area?

You do know that ported and vented are the same thing, right?

So you can't provide a source. I don't need directions to the library (I went to Uni there) but was asking for the name and author of the text(s) that you are using to justify your claim. It is in none of the works I currently own.

Port is circular. Vent is slotted port. I have not seen circular vents on a pro cabinet in years. Yes it is the same, until you go below 30hz.

Irrelevant. It's still correct: it was just the easiest to quote. I'm still happy for you to quote from a reputable source that it's incorrect.

Andy, is your only reference for hearing a HT with 4 subs the one set up by Klipsch that had a 200hz crossover? Of course you could hear dialog from the subs with a crossover that high. You should browse the thread that has a list of people that will demo their subs for other members. Go listen to a system with 4+ subs then report back.

I wasn't commenting on whether you believe Audyssey is of any value or not - just the fact that you had never even heard of it. It was an example of how you are not in touch with the needs, requirements etc of home theater audio.

Lol. You guys don't need to have to "tap out". This discussion is valid and obviously a lot in here know how to recreate "commercial theater bass at home" so ... what's there to be afraid of?

And if necessary, exercise that ignore button.

I still want to know about the advantages of the "bass reflex walls" with the port/vent into the attic (and not the listening area), and how there's a difference between "ported" and "vented" below 30 Hz. And why "ports" are round, but "vents" are slotted.

This has all the makings of a revolutionary white paper to be submitted to AES.

Guess i'm an audio rebel, my subs (I run with 2 ) have slot ports and are flat to about 16Hz while cruising along at reference all day long if I desire.

We've often been asked the question, "Why not just remix the soundtrack or apply a form of filter to it when mastering the home video?"

While a noble sentiment, it does not eliminate the need for Re-Eq, because we still would have an existing archive of home video material that needs it. Looking forward, given the variable in playback systems, there is, in the opinion of some, little utility in applying a filter in the transfer process (from cinema master to home video master). It’s an extra step and 80% (or so) of DVD viewing systems are operated well below reference level such that a bit too much HF energy goes unnoticed. At the same time, we are seeing an ever increasing number of titles whose soundtracks are in fact "redone" for home theater (most noteworthy are recent titles from New Line Cinema). These come with the stigma that Re-Eq is not required or appropriate.
The problem we face right now is one of trial and error: When we take that new release DVD rental home, will it be better served by having Re-Eq on or off? Who knows? We as consumers have very little to go on in this regard other than our own ears. THX (naturally) advocates the status quo with Re-Eq, in place while other industry professionals openly advocate remixing the soundtracks.

No one ever said being a home theater aficionado would be easy.

You still use DVDs?

Have you checked out Roger's HT? It was a home theater of the month recently here on AVS....

I haven't read the whole thread, but I don't think anybody mentioned tactile. If you do D-BOX you get a lot of low end from that. And its in some of the better commercial theaters.
