I went with 3 and 5. Other that one being about 1db down against the other they were identical. Now complete. Sound absolutely fantastic. No distinguishable different between them.
The speaker appears to have an SP1003 bass driver, but the crossover idms for the later SP1228 driver. This will give a frequency response nothing like the BBC specification.
@@D100hughesMorning Derek. REW and a calibrated UNImic1. I spent the time getting the set up right. I use it a measuring space I built in my office. Pretty good down to 200Hz. When the weather is good I measure outside but living in Devon that's not often 🤣. I use DATS to for impedance testing.
@@haycrossaudio5474 I am on the south coast in Sussex, if it's not raining it's probably too windy for testing outside! I use the Clio system with their mic or one I built myself.
@@D100hughes 🤣🤣 yeah a windy day isn't ideal, or rain 😃. One day I hope to invest in CLIO but for now REW works nicely. The results are good enough for what I do at the moment. I've got a little line of BBC inspired speakers I'm working on so if that takes off the definitely CLIO. Nice to chat to you. Some of my other videos might be of interest. Cheers. Matt
Thank you for opening this little speaker cab. I can see where Brits lack in over all build quality. Many mistakes made by Rogers adding un necessary items due to lack of over build quality. Brits are known for being Brutal, bad teeth and just NOT that intelligent. I could easily improve these cabs and eliminate some of the un necessary items in the build, im not even a speaker builder. "Why would they mount the cross over so close to the tweeter they needed padding?? Just slow/dumb. Use 16th rise screws and the cross over would not even touch the tweeter, giving more cooling and breathing room between items. No res media. 16th of inch is all needed, maybe slightly less. I'm German, we do things precisely.

Love your vids. Solid work sir!

I'll post all the measurements taken in part 3. Nothing stood out. Sounded lovely to. They were made up with what I got sent though.
@@haycrossaudio5474 that will be interesting. What equipment do you y use for testing?

I'd go with (I think) 4 and 5 - the ones that are the bottom 2 traces at 20khz
I'd think 3 and 5 because those match best under 10.000hz
Winner 😂
@@haycrossaudio5474 🥳
for accuracy, the bottom 2; if your customer is of advanced age/hearing, the top 2 might suit him better....
