AV Rant #990: Interpreting Graphs

October 30th, 2025

Tom’s move in continues to progress. Warner Bros. Discovery is officially up for sale, but most prospective buyers only want pieces of it. We answer questions about tall subs, maximum output capabilities, lots of graphs, and much more.

00:00:00 – Intro

00:01:42 – Tiny Bit of World News

The USA and Canada are fighting again, and all because of a TV ad?

00:04:10 – Personal Updates

Lots more news about Tom’s move in, and what’s going on outside his window as we record.

00:14:15 – What We Watched

Tom watched Artistic Gymnastics European Championships – Mixed Team Final: https://youtu.be/wdilp8B7Nts

Rob watched Weapons. And he’s been listening to EJAE’s new single, “In Another World”: https://youtu.be/fSzpkgeotB8

00:28:44 – Listeners of the Week

Our Listeners of the Week are our 128 Patreon Patrons, as well as Anonymous for sending Rob an Amazon gift card, and Ren for offering to send Tom a whole bunch of movie codes.

We also appreciate the notes of gratitude for keeping the podcast going from: Nelson, David, Ryan, Ilango, Infinite Gary, Rohan, Karl, Sasi, Gurinder, and Anonymous. Thank you to everyone for continuing to listen!

In the news:

00:31:20 – News: Warner Bros. Discovery is For Sale

The plan is still to separate back into two brands. But the whole company is officially for sale now, although most prospective buyers only want pieces of it: https://tinyurl.com/y5u7d2z3

Comments:

00:38:07 – Comment: Nelson – David’s Church’s Speakers

Nelson is familiar with the mixing board being used at David’s church, so he has some useful suggestions for getting their system working.

00:42:50 – Comment: Greg – Battery Pack for Recliners

Rather than covering an extension cord with a rug, why not power your recliners with a battery pack?

QUESTIONS:

00:46:25 – Infinite Gary: Closing Brands, Dialog Boost, and UB9000 Issues

Considering how many sub-brands Harman still runs, do we think Samsung might avoid closing down any Sound United brands? How do we handle situations where we want a temporary dialog boost? And can we figure out why his Panasonic UB9000 stopped outputting any video?

00:58:21 – Dev: Graph Confusion

He can hear, and measure, a dip in his Front speakers’ frequency response, but different types of decay time graphs seem to show conflicting things in that region. We dig into why, and what can be done about that dip.

01:14:48 – Mohsen: SSD or Spinning Hard Drive?

With his SSD nearly full, does he get another, or a different type of storage?

01:18:07 – Ryan: Maximum Safe Output

We go through figuring out just how loud his 1st generation Elac Debut Towers can really play, and whether he needs an external amp.

01:30:36 – Ilango: Tall Subs, Dirac, and Future Speakers

Should he buy his subwoofers earlier than planned since SVS’ cylinder models seem to be going away? Will he be a good candidate for Dirac ART? And thoughts on his future Front 3 speakers.

01:52:22 – Rohan: Unfixable AV Receiver?

Repair shops have been unable to replicate his problem. Is it simply time to buy a new AV Receiver?

02:01:28 – Sasi: Ugoos AM6B+ Popularity

A comment, not a question: Sasi explains to us why the Ugoos Android TV box is so popular with a certain crowd online.
