Thanks for your comments. I have removed the OTT thick insulation, anyway - there is space around magnets. Been put back a bit today.. The tabs broke off one of my Speakon sockets this evening, Neutrik ones as well. Wasn’t impressed they had spade connections in the first place.

A syringe……. but you could use a 100 psi airline

Retraction pocket, that may be what’s wrong with my ears currently. GP cannot see any wax in my ears at all. Waiting for ENT consultation, I have tinnitus, an 8k whistle to be more precise, when I had a hearing test recently. My ear rustles and clicks when I walk, only been going on since March, but...

Being stupid…. The battery test revealed that one of the drivers on the second speaker was connected in reverse, sorted that. The driver was wrongly designated by SEAS. The impedance spike has moved back to 40hz same as the first lightly stuffed cabinet. A SPL measurement shows no difference in the ...

Managed to measure the response of the lightly damped and over damped ? subwoofers. The results are interesting. The extra damping equates to a 20db reduction in response. How much of this is the undamped resonance, is the question. Blue trace is the under damped cabinet (obviously) EB50685C-D080-49...

Got a chance to experiment with the stuffing of the subwoofer boxes. Changed the rockwool fibre pulling out and added some wool fibre wadding, added it end on 5” deep tightly so the wadding comes upto the back of the magnets. 70BC187B-34CD-468E-8F4B-989DA405A519.jpeg This had a positive effect on th...

Some of my ex uni peers have already left Ford, as they have closed down the power train design business in Europe, as these skills aren’t needed with EV’s.

The automotive industry have already put wheels in motion to retire IC engines, they won’t be be changing their strategies. No elected body with a life span of 5 years really care about environmental stuff where the effects are outside of two terms in parliament.

Installed the sub drivers this evening. Quick check with DATs didn’t give me what I was expecting. I initially built a test cabinet of 26 ltrs internal volume and tested the seas driver. For the actual one I am using two drivers in parallel, in a box of internal volume 52 litres. Both boxes fully st...

After reading up abit more, this was informative https://www.soundonsound.com/reviews/ch ... -absorbers

I have decided to go with rock wool insulation, the melamine foam is really only good for above 600 hz. Using the melamine foam in the rear chambers for the TPL’s.

Maybe I am going mad…. Well that’s what SWMBO thinks. Been laying out the acoustic treatment for the midrange cabinet. Interesting discussion on DIYAudio about using melamine foam for absorption. With a hack of using magic erasers, as they are an order of magnitude cheaper than buying it in sheet fo...

Thanks for the clarification, if I come it’s increased the attendance by 50% I suppose it’s the lack of hotel rooms which is the challenge.

What happens on Sunday? As I have never been there the day after… Why I ask is I have a clash on Saturday Evening and will need to leave by 4:30. (Also Dave is getting tired with his condition nowadays) Do we leave our set ups in the hall and then carryon on Sunday? As leaving my set up and then com...

I have surplus to requirements a Innuos Zen Mini Streamer with 2TB of on board storage. Bought this for the upcoming shows as a stand alone streamer and DAS. I was surprised that it sounded better than my existing NUC with Dalphile, that I went and bought at more expensive model. It’s loaded with th...

I tried wrapping a test piece, it wouldn’t shrink enough to be able to do the horn profile. I have gone for a deep red, so we won’t clash now at Owston
