    Agree Reli. I don’t think the price is unreasonable for the style and rich feature set. Most importantly, I hope it sounds good. My best guess is that it will sound better than a true upper tier vintage unit, but will fall short of exceptional sounding products like the Tivoli Songbook Max or the new WAR boombox. I think I could live with that.
    While we’re on the subject, I previously owned two Sharp GF-777’s and if I’m being super honest, I didn’t think they sounded that great. So for the BB-777 it’s a low-ish bar.

    You're correct, the GF-777 was never a hifi box. The bass is muddy when you push it. The Bumpboxx hits harder and goes deeper. I've played with it a couple times at their company office, and it handles hiphop and electro really well. I didn't try other music genres though.

    Any thoughts on the treble when you listened to it?
    4 tweeters (2 horn, 2 dome) had me concerned right out of the gate. Two quality domes seem like a better choice. Brash, crashy treble would really kill it for me.

    I didn't notice harsh treble, but I think you would need to listen to classical or acoustic music to really get a sense of that. I don't know what Techmoan listens to or where he set the tone settings.

    It makes me wonder why they chose 2 horns and 2 domes. I sold audio for years back in the mid to late 1980’s…everything from low end boomboxes to Harman Kardon and Advent. In all my travels I’ve never seen an Audio company put 4 tweeters on a speaker set up, let alone mixing domes and horns. I can’t figure out why they made that choice. In the end I’m not sure I care if there’s solid fidelity.

    i knew a few people who had a 777 in the 80‘es and they all finally either had other spaekers fitted, or solt the box. i used to have one for many years, with original speakers and i agree: shitty box ( but nicee !).
    this remake is great, i consider one.

    I've actually seen lots of home speakers with multiple tweeters. Check out the 5 tweeters on the Micro Acoustics FRM-1 and FRM-1AX

    One of the Bumpboxx guys said they were worried that the horns wouldn't be enough because they were too directional. Horns aren't any good if they're small and your ears aren't lined up with them.

    22 Hours to go...

    They've answered all of the questions on the Kickstarter page, and have posted 2 videos. They said they are going to post more.

    I switched to the Black version, i like it better than the Red.

    Sounds like delivery is going on now? What a M90 is next with soft-touch buttons?

    It'd be nice if they came on here, over 10,000 views on this thread alone and these are high-value eyeballs!

    Yeah, mine has been packed into the shipping container and ready to board the slow boat from China.

    At least that's the way I read this:

    "2026-07-21 09:00 am Container stuffing completed. Vessel: [ETD:7.26,ETA:8.10]"

    as estimated time of departure on the 26th and estimated time of arrival (in CA, USA) as August 10th.

    We were living the hi-life 20 years ago when ebay was new and shipping was nearly free. I used to get tiny parts from China for nearly-nothing shipping and it would show up around 10 days later.

    I have to believe there's a lot of hand wringing and bumps in the road with a project like this.

    I'm not sure the "Twin Cassette" mechanism is any more than a cheap chinese off the shelf mech! - Correct me if I'm wrong but I'd love to know more about the tape performance on these.....

    This is a post by Rob Owens, who runs Bumpboxx about the Cassette mech (if you click on it, it's slightly legible lol):

    I wonder if Techmoan is on the early list, his boombox videos get a lot of looks.

    Techmoan got sent a pre-production unit.

    He spent far longer than he expected making the video due to the number of issues he found. Hopefully those will be corrected in the production ones.
    He has since said that he cancelled the Kickstarter order he placed a long time ago as he had got a feel for the unit from the one he received and didn't need another.
    I suspect for many people in places like the U.K. the size of the unit would be a problem. He couldn't do a comparison with the Sharp GF777 original as that had gone back to storage to free up space.

    If anyone is wondering, we get to learn these things from his Patreon updates.

    To show he doesn't moan about everything the Teac CD Radio he reviewed this week gets the Techmoan seal of approval.


    At the end of that video I was thinking the BB777 would have been better with that Tuner and CD player fitted.
