Ray

Perfect

Hi Ray,
I'll take them if they are still available

Drum 'n bass?

Its almost perfect for what I need. Lots of rooms, 1 for my workshop, 1 for lighting studio, 2-3 dem rooms, storage of stock then where all the patients used to sit (waiting room) a huge area for meetings!!!!! Plus lots of nice folk off AT who will help me move in in exchange for vinyl?????????????...

Hi Simon I'm curious as to what can be achieved with this evaluation. I did some very amateur studio measurements back in the day but didn't get very far with nulling bad reflections, other than identifying places to put auralex. Apart from reflections and resonant points what else can be done with...

Ah, nice - good work. I suppose it's not much use putting them up as you need to see them 'in action' ? Does it require you to drive the sound into the model in a certain place - ie. where the speakers sit ? I do remember in the bass when testing the tapped horn, from the typical listening position...

Hi Mark, Finally got round to grabbing some of the room mode results for you, this is early days as it is just the bare room with no fixtures and furniture. I've got the pretty pictures for all the different modes, but they don't show much apart from it gets complex once you get past the first coupl...

Ordered just now !

Mine should be on its way too

Thats more than enough to get it underway, a few degrees or cm out either way don't make a lot of difference at the wavelengths we are looking at... Simon C I've got some initial results, just trying to figure out how to share them on here as the numbers on their own are not that helpful without th...

Info here for SimonC - Front room looks like this , if you want to estimate room modes . Dims in metres. Width of room doesn't quite work out with sections of bay added together, at least on the assumption the side windows are a 45deg to the middle one - maybe they are not ? Derwendeg_frontroom.png...

Just waiting to offer my card details - http://www.hornspeakersystems.info/ http://www.hornspeakersystems.info/images/pdf/TOC.pdf YES :D :D :D Just skimmed the TOC and its looks like it looks like a greatest hits tour for horn design history, theory and application.

The 30k may well be from the pc that you are using to measure, or any other switching supply in the region. OK, thanks Nick. I might try running the laptop off the battery tomorrow. Would be good to get to the bottom of it. Might become a problem in the future when I'm measuring phono stages ... I'...
