Just confirmed with Dave, that he’s coming to Owston too. He might have a system to play too.

Uhmm. A night out down the quay side, was a bit like a war zone, in the 1980’s from what a remember, but that’s where the similarities stop.

Testing the new speakers out…. Playing Gaza - all 17 mins of it. It’s a good track to test out speakers, if you can listen to it all the way through, the speakers are a winner.

Maybe I will post the TS parameters for the driver in free space later. I have finished the first of these smaller speakers.. just listening in mono until I get a chance tomorrow to finish off the other, and fine tweak the crossovers. Dave’s coming around Saturday to see if they are worthy of bringi...

Measured the Beyma 12p80nd drivers last night, both very similar frequency- resonant freq in free space 60 hz, Way off the 47hz quoted on the spec sheet. I had these in opposition with some LF driving signal for 24hrs to loosen then up earlier in the year. Maybe I need Chris driving them to x max 52...

That’s a relief. I just didn’t want to be the only one with dodgy DIY speakers.

Just looking at the WAM show equipment list to see what Steve S is going to unveil this year…. commercial kit speakers.. what’s the world coming to.

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...
