3RS-ing a Commodore Vanderbilt

Great job Mario! The TB speaker adds so much bass. Awesome.

Thanks Jonathan. 

I did forget to mention that I used Red N Tacky, dispensed by syringe, to fill the grease pit in the transmission on the center axle, and in the grease axle fills for the lead and trailing drivers.

Thanks for the Tang Band reference. I'm trying to get speakers into my 1969 Corvair without cutting anything. These look like a great possibility.

Mario, what is the first 3 digit number on the left side on your spectrum analyzer scale, x axis? I am guessing 160 if those are octave divisions but can't read for sure.

They're 20Hz between the vertical lines (major & minor grid lines) from the left margin to 110Hz. Then goes up from there.

The sound is roughly in a bell curve from 110-1000Hz, or the bottom half of vocal range, and the sweet spot of "orchestral range".

Again... not bad for 1996 technology. 

Oh, and the volume was not turned all the way up. 

Thanks,

Pretty impressive. Anything below 200 hz is good. I will have to check out my dual fatboys with Legacy RS for comparison when I get mine done.

I was having the SAME conversation with Marker last night!

We were comparing and contrasting YouTube videos of locomotives with dual Fat Boys, and we can't. The spectrum analyzer was no use, as the speakers of the phones and the questionable source of the videos (my iPhone is set to 4K, but most videos weren't even HD. 

I'd LOVE to see your results with the same app, and then we can even meet up in person at The Club (I have a key) and we can compare. 

This is fun!

thanks,

What app are you using? I have a 35 year old analog audiophile 10 band spectrum analyzer that has a calibrated mike. I can also take the audio out of that to a USB DAQ and use computer software for finer analysis.

Summer finally arrived so it may be a while before I get to this.

Haven't heard from Marker in a while. Good to hear he is still participating.

I love Tang Band speakers. The smallest module even fits into and S scale SW-1

I know!  I subscribed to your channel and drool over some of your work!

I'm using an app called Spectrum Analyzer.

I'm sure it's not calibrated and totally not even close to what you have. I'm jealous. 

Heres a screen shot of the app, on my iPhone 7+, and next to the unit:

Meanwhile, I talk to Marker just about everyday. He just took deli every of his Atlas F7s, and we've been discussing that. 

Thanks,

Thanks for the kind words. I grew up with a musician father who owned a recording studio so sound is pretty important to me

what if I have an Android???.... don't say it Mario!

Never heard of Tang Band speakers. Thanks for the tip.

Which speaker model fits in the tender? Does it just plug and play replace?
