I will happily start a thread re: low end Atmos if anyone is interested. I want to remix some material I released in the mid-80s in Atmos, which will be an interesting exercise of extracting stems and doing cruel and unusual things to them ;) A sort of "director's cut". For films, I think it's...

Well each to their own. I just find movies (in general) staggeringly boring, utterly predictable, pointlessly violent -- and a waste of my time. I read some 200+ books a year, and when a movie is made of a book I enjoy, it is almost invariably disappointing (Bored of the RIngs? The Gobbit?). The...

I am overall utterly uninterested in home theatre, don't watch television and avoid almost all films, especially most Hollywood product (with exceptions). So I am here for the the sound side only, specifically REW and sub theory content. My wife watches both TV and loads of Hollywood movies, but...

I spent years as a totally-not-famous but competent mix engineer. At 73 my HF response rolls off sharply above 12 kHz, but when CD quality became available and I still had 20 kHz available I was almost instantly convinced this was an unbeatable format for consumption, even with dodgy companding...

When it breaks... I don't watch TV, my wife does.

I can't conceive of being deaf enough to listen to vinyl again, except for transcription purposes. I suppose if my ears deteriorate enough to enjoy it -- it won't matter. I detest whole house music systems, I only use paid Tidal to keep an ear on new releases, and only listen in my studio. If I...

Sorry bit busy. Will try and answer at w/e

Thanks DanDan for your correction. I have not yet seen any point on which we disagree. I can't see anywhere that I recommended using quarter-wave techniques: I am simply attempting to explain first principles; hand out a fishing rod rather than a fish. OTOH, if you want to maintain that...

Thanks for your comments, DanDan. You have highlighted a rigid panel absorber with a treatment on one face which means it does not absorb much at high frequencies (note the 0.23 figure @ 4KHz) but is effectively a membrane absorber at lower frequencies (ie, @ 250 Hz. And yes, of course, standing...

Bass treatment in a small room: How to achieve the desired effects. First, what are bass frequencies? I can’t find an agreed definition. Wikipedia says 16-256 Hz, in other words the musical bass definition. For me, bass mainly is less than 100Hz, that is low bass instruments, bass drums, and so...

Re duvets: I, like you, am keen on 'natural' materials, especially against my skin. Bulk cotton (like futons) can be useful in audio, wool, and particularly longhair wool, more so, especially in speaker design. But polyester duvets are very effective if thick and dense enough, which is why I...

Part 2 OK, so the plan: we need to add some bass trapping. we need to deal with wall reflections from the speakers. we need to deal with speaker placement and comb filtering (SBIR). we need to make the room as symmetrical as possible at mid frequencies and above Then measuring what we have...

So, what I'm going to do is tell you what I would do with your room and why. I'm actually recording this in a very similar sized room which has very similar problems. One advantage I have here is that the ceiling height is quite a lot greater so I've been able to put lots of stuff on the...

Sorry for delay, got stuck with stuff. Will post today.
