Hi Drew

Nothing happening due to Covid.

Although I did hear that the virus can not survive in an anechoic chamber!

Mr Tanner,

Have you read any of the articles from the following Canuck, Mitch Barnett,

https://accuratesound.ca/

https://audiophilestyle.com/ca/bits-and-bytes/what-is-accurate-sound-r923/

https://www.amazon.com/Accurate-Sound-Reproduction-Using-DSP-ebook/dp/B01FURPS40/ref=sr_1_2?crid=2D1EW3KDS1YVD&dchild=1&keywords=accurate+sound&qid=1595199597&sprefix=accuate%2Caps%2C222&sr=8-2

I plan on using his services to make a too big speaker fit into a small room (using ROON). I am in California and he is in Canada.The plan is to do this remotely. I have not done this yet so I cannot give endorsement but he has great reviews and maybe someone whose DSP skills could be useful for Bryston to have a discussion with.

Hi YYZ

Interesting articles and I agree if you are going to use room EQ at all keep it in the low frequency range only. 

On our active speakers we provide a GUI that allows you to utilize EQ below about 150Hz.   I only recommend it's use if absolutely necessary.

One caution though is do not ever try to add energy to the room just reduce the peaks using EQ.

Anther concern is that when you listen to a speaker in a room you are listening to the "total radiate sound power" and not just the on axis response the mic 'see's" at the listening location. The brain and the ears hears totally differently than the way a mic picks up a signal at a single point in space.

PS - talk about multi-driver arrays!!!

Hi Al,

Yes I put a demo system together and was reasonably happy with it but COVID and parts shortages got in the way of any further progress.
