Looking forward to the crossover upgrade video!

Thanks for taking the time to show us the inside!

Nice V.C! ....Way better then G.R. Research,whew!!

Bonjour de la France.......... un grand merci, j'adore votre chaine, voir l'intérieur des enceintes acoustiques est vraiment passionnant............

Love the channel. I bought these a couple days after you did. The next day the sale price was gone. I can't imagine a better speaker for $349.00. At $700 the competition stiffens up. BTW I listened to a lot of RU-vid speaker reviews and just couldn't take it any more, so I asked Chat GPT to write a speaker review using words to describe a fine wine. This is what I got - Indulge in a sensory symphony as you explore the rich tones of the AcoustiVine™ Chenin Blanc speakers. Like a fine wine swirling in a crystal glass, these speakers offer a bouquet of harmonious notes that dance upon the palate of your ears. Upon first sip, or rather, listen, you're greeted by a crisp clarity that sparkles like a freshly opened bottle of champagne. The highs flutter delicately like the effervescence of bubbles, teasing your senses with their airy elegance. As you delve deeper, the midrange unfolds like a velvety merlot, smooth and full-bodied, wrapping you in warmth and comfort. Each note resonates with the depth of a well-aged Chenin Blanc, leaving a lingering impression that tantalizes the soul. And just when you think you've experienced it all, the bass sweeps in like a bold syrah, commanding attention with its robust presence. It pulses through the room, filling every corner with its deep, resonant tones, inviting you to lose yourself in its intoxicating embrace. With the AcoustiVine™ Chenin Blanc speakers, every listening experience becomes a journey of discovery, a sensory exploration akin to savoring a fine vintage. So pour yourself a glass of your favorite audio and let the symphony unfold before you. Cheers to the perfect pairing of sound and sensation. I'm looking forward to the crossover build.

I love speaker teardown videos and you have the best ones! I tore down one of my JBL 620 speakers and found mostly the same things: Drivers appear to have the same magnet at ~ 4" diameter with the 5.25" woofer weighing 3 Lbs 9.9 Oz and having a resonant frequency of 56Hz. The crossovers are similar with the 620 having one less iron core inductor, one less electrolytic cap and two fewer resistors. Port tuning on the 620' came in 1 Hz higher @ 44 Hz. The component differences could explain the shape of the impedance curve I got. Instead of a steadily rising line in the tweeter's band, the 620 had what I'd call two rising peaks; a smaller one at 1.2Khz and a bigger one at 8Khz with the dip between them at 2 Khz. I'm wondering what effect this has on the sound. I had previously commented that I was skeptical component upgrades would have meaningful improvement on sound quality but after seeing all the modification you're working on, I'm not so sure! Can't wait to see what you find!

Hi, Just stumbled accros your channel. Nice video's. I've also experimented with the purple CSA caps your about to use in your project. These are great! They are very neutral, and don't seem to color the sound. I love the midrange detail, and transparancy. Soundstage is good. These are my goto caps for future projects. Good luck on your experiment, but be sure to also upgrade the inside wiring to teflon. And use a decent source.

Another great video! It’s really interesting that though the midrange drivers had such significant differences, it sounds like it’s not all that audible in practice. At least not enough to deter you from liking them. It’s a very handsome speaker.

Thanks! Had I not seen this video I may have bought them - but the mid woofer disparity is a shame.

Great video. I own the JBL 4367 and 590s. I feel like my 590s have perfect left to right balance of the drivers (soundstage is locked and centered) so I wonder if this is a bad batch or if their quality has dropped. Sonically the 4367 is amazing, best speaker ever, but man it is ugly lol.

Hello, I just came across this channel. Have you done the same test on Q Acoustics bookshelf speakers? they seem to be a big hype, I wonder how they perform?

1:00 seat the speaker in front of a mild fan space heater for 10 minutes. It'll soften that kind of glue. Just amke sure you aren't damaging sensitive plastic parts on the drivers

As a Jbl fan I quite like these. Nothing is perfect. I am surprised about the 12 and 13 percent measurement differences. Years back I think they were much more meticulous about driver quality. I run more vintage jbls including the L112 and L100 centuries. And pro drivers like 2226h for reinforce ment of my altec 604 8H Urei monitors. The horn in your 630 looks great. Having a small woofer keep up with it would be a crossover challenge which I'm sure Jbl address. I'm not an engineer just a long term audiophile. Many are snobby about Jbl still. When you use amps like Accuphase and Luxnan and better Rotel they shine. Although efficient Jbls like current and watts. Your high end parts will bring suitable improvement. A mate of mine who is a professional tech upgrades all sorts of speakers and the components make big differences.

I’m more curious about where you got them for 50% off and did I miss the sale??

Three metal core coils on the woofer? They must be using a 4th order filter (using 2 of the coils) and a notch filter uses the 3rd one? Seems that the woofer needs some serious work to pull it into line.

This one vs the JBL Stage a130? Has anyone compared both? People tend to really love the a130. If anyone can comment I'd really appreciate. I'm planning one getting one of them soon. Thanks.

Your link to Amazon for the Studio 630 shows them at full price of $699. Just an fyi.

Awesome work \ (•◡•) /

You did a great job of deciphering that speaker! The only thing I didnt like is that you sound-speak like the guys on Motortrend. You sound like one long infomercial- tonally.

Are Q Acoustics speakers on your radar

Would like to see the inside of the Micca RB42 Reference.

Maybe I missed it, but can you explain any break-in process? If any.

Explains the 50% offf... mismatched driver batch

This explains why I was underwhelmed when I heard them. Bad quality control.

Taco tweeter 😬
