Sounds about right. I'm a casual fan of F1 and much more into motorcycle racing. I'm pretty bummed that we're down to a single MotoGP event and that's clear down in Austin TX.
I went there for the first MotoGP running in 2013 and it was ok but from a fan perspective, it didn't hold a candle to Laguna Seca. 2013 was the last time they ran that track and it was my all-time favorite race weekend. At LS, they really catered to the fans, at COTA, they tried to bleed every last dollar out of your wallet.
At the end of June my boys, grandson and I will be camping trackside for our National Superbike series. Its not the same but I'm really looking forward to it.

I’m glad you keep up the Moto GP interest over there. It’s a low key sport regarding tech, therefore I like it. Having done some racing myself on two wheels.
how's that?
nowadays MGP is almost F1 on 2 wheels
all those lowering devices, electronics and aero .......
Right speaker treatment. Widening baffle and silencing the body. You”d be surprised how much your spks spks outside membrane.
Hello Stajo,
I am absolutely on the same way like you - dampening loudspeaker cases is important. Finding the right wood (or other material)
and stiffening the body of the speaker against vibration is an interesting journey.
Often some kind of vibration is good - I compare it with a body of an music - instrument: some kind of vibration / resonances or
overtones can be heard as very pleasant...I try to dampen my speakerbuilds.. If I knock on the case of the speaker - dull, dampened knock should be audible.
Have fun!
Cheers
Dirk

About properly building a speaker enclosure.
20 years ago I was building up a street/track/audio comp car project that I ran some time trails and won sound quality and a short lived but interesting new format. I needed a light weight but very solid sub enclosure so hammered the tire well into a curved bottom shape, used BB ply for top in layers were needed and drill out braces and fiberglass. I was 2 cubic ft and weighed 20 lbs empty and solid as a rock. Though built for just sound quality events I entered 3 events that included a 2 minute music SPL section instead of the tone bursts used by the normal comps most orgs used. I finished in 2nd place each time beating the big SPL builds because then could not run for 2 minutes, some blew the amps, some blew the speakers, some caught fire.....On a music track I averaged 138.4 dB which is insanely loud for a single sealed 15 with 1kw power. The sub only weighed 12lbs, the amp 8 lbs, the car with a roll cage was 200lbs lighter than stock but fully sound deadened including over 100 liquid ounces of high grade expanding foam in the chassis and over rear tire wells. Even at that high dB there was no resonance in the the whole car, hundreds of hours went into the sound deadening part of the build though. It did finish 2nd place in a national level TT event against pure race cars, would of won the next day except the 5 holes in the block and oil fire I put out after going off the track backwards at 100MPH, that was interesting.
I won the overall SQ/SPL at those 3 events, handily, kind of fun having ribbon tweeters on the A pillar bars of the roll cage, two full wrap around with head restraint race seats, etc.....it was fun cranking up the system while waiting to go out on the race track as well🙂

It was not the sound enhancements that originally got me in to the idea of enlarging them. It was rather that they are already so big that they take up a lot of room and attention, and I thought, why not build them into kind of sideboard furnitures, so they blend in in a different way. But it was very noticeable how the baffle widening enhanced the low mid with less baffle step and diffraction. Next step is to dampen it with asphalt and isolation, then wrap it up with an exterior.
The titanium one has a little harcher tone, the alu is a wee bit softer to my ears. It’s just to lift the back lid, extract the titanium with windings on and chuck in the alu one.
well, sorry, I know how, was really asking about origin of Al 'fragm which is better to ear than Ti one
They were for sale for a while, now I think there is newer models of 15 inch beyma coaxes. It’s pro series, made for stage monitors etc
