That's a great test vid! My V2.0 drivers start vibrating right from the start but the sound doesn't come in until around 30hz - very interesting (for me at least)fromNKLwithlove said:

Interesting for me too, very interesting because the Century - whose maker cites only the flat part of its response in the book, which gives an unnecessarily pessimistic impression of how hard it can actually thump - hurts my head past 40Hz and by the time the test tone reaches 51, it has caused the liquids in two small bottles on the hearth to behave like the waves do on the back garden when there's a storm to sea. The pinch roller conditioner, largely glycerin so pretty viscous, sloshes harder and rocks the bottle but the head cleaner, IPA with an anti-corrosive ingredient and not more viscous than bog standard tap water, shuffles across the tile on which they stand and the liquid in that one moves much more excitedly.
I knew from my dubstep listening habit that the B&O's 4" woofers were remarkably able for their size but seeing thae wee bottles dancing to a Knife Party track was amazing.
Same test with the laptop's BT output going instead to the PC-5 (also only 4" but this time full range) shows that it renders the really low notes just as loudly but not with the cleanliness of the Century and this is really weird, because although I think that I'm hearing much the same thing from the solid sounding little JVC, it's not hurting my head. Is that because its bass response lacks the definition of the Danish machinery, so doesn't affect the human brain in the same way as a much more focused, accurate rendition with fewer cabinet-induced harmonics?
So in reply to the actual question that Rick asked: No, that statement wasn't strictly true because the long travel, softly suspended drivers of a good PC-5 can do a pretty good job of making accurate sounds at well below the 80Hz but to find something that goes lower with far greater accuracy, look to a slimline, one-piece bit of kit from Denmark that could arguably (it's OK, I won't
) pass as a boombox if only I had a battery tray for it.
Even less predictably; the laptop - whichever of thae two devices its audio is being routed to - provides purer, more solid bass when the connection is via A2DP than when I swap the BT output for the solid state connections from its line out jacks directly to the DIN sockets on either JVC or B&O, suggesting that A2DP is better than physical connections.
That, Jeremy Clarkson, is genuinely a bombshell...

Have fun,

That's a great video of the 808 but there's no examples there of any of the really crazy low end bass it became coveted for. A 808 kick or Tom for that matter detuned made for incredible low end . A lot of people used 808s in early hip hop but a crapload also used samplers . Often a 808 pattern would be sampled into a emax .mpc,or akai. You also should remember even a 808 would have been equed ,compressed, or processed in some other way. I guess the point I'm trying to make is a lot of those recordings have a large portion of low end cut from the on go. I mean if you didn't remove some of those frequencies from the ongo you'd just end up with a wall of lowend that buried all the other sounds. A lot of times things were done to analog drums to make them stand out. Sometimes even distortion ,overdrive or adding harmonic distortion in other fashions was used. I don't have a 808,909 or even a 606 anymore. The point is this . A 808 detuned raw into any boombox with a long decay can seriously cause mayhem for a lot of speakers. I literarily watched a lot of speakers decimated before my eyes doing this. When I first stated making electronic music I was lucky to score a 808,909 and 606 . A country music studio a block from where I lived was going DAW computer based . Well to make a long story short I bought all of his drum machines. 150 bucks . I didn't sell them for that lol. Anyways I kinda think the bass way to test bass is to get one of those test recordings and do it. I mean I still have some stuff here that can destroy any boomboxes cones. I have some nice Tannoy monitors even they get pretty crazy . I mean if I hook a ladder filter up and set it to self oscilate they move the speakers so violently its unreal. Even when it's at such a low frencquency it's in audible to human beings. As mr super duper said its more about roll off than reproduction. On so many recordings that bass has already been rolled of by the engineer / producer in the studio.

Sounds pretty accurate to meLasonic TRC-920 said:Rick, the TRC-975 and it's LBS system hits about as hard as any Big Blaster and really moves the speakers, but again the EQ only goes down to 100hz.
I think that the mid 80's was the very beginning of the low bass revolution. RunDMC's "Dumb Girl" was the first time I ever heard a song "Built" around the BOOM and that came out in 1986.
The Kabooms hit harder, but those are 90's bass tubes, not classic blasters.
I have never heard a Studio 1
And like many said above, just because the spec sheet says it, doesn't mean the radio can reproduce it. The amp might have a freq response down to 30hz, the speakers might have a freq response down to 30hz and the tape head might have a freq response down to 30hz...but collectively, in their circuitry do they deliver?
I don't think so. I think in the mix of caps, filters and other components on the amp board they don't and they DON'T because the music of the time didn't call for it (YET!) I think they used components (in the higher end radio's at least) that had spec's down to 30hz to leave enough "Head Room" in the collective components to deliver un-taxed quality sound.
But then again, I have no proof, I am just talking out my arse!

You're spot on Bill. I felt that 808's weren't to their full mainstream status yet in that time period.bill said:
Do you feel that BECAUSE of the creation of the music you described in your second post that stereo equipment was forced to evolve to keep up with the power of the music? Kind of seems that way to me.

The same way Beats markets their product based on the fact that it can (in theory, or lies) deliver music with heavy bass

Your dead on. The ipod really swept in and changed how we buy , store and listen to music . What amazes me is how simple the beats concept is. Hey let's add a battery powered headphone preamp to a set of cans and boom. I'm pretty sure because louder is often what many people consider better is why people rave on those phones. I mean there's only so much power coming out of a ipod headphone jack so....Lasonic TRC-920 said:
I guess when you look back at most audio products it was all marketing . Remember the guy who sold you that cd player telling you that you needed digital speakers or your old stuff.

I mean if you go to a lot of studios now you will see a sub woofer in the Control room along with monitors. I also suspect a lot of remastered classic material has different frequencies boosted that were cut on the original masters. That being said if you chuck on a Bob Marley album that was produced by Mr Lee scratch perry there's all kinds of stuff on there you won't notice on a m 70 that you will in a crazy over the top car stereo. In addition if you play that same music on a nice home stereo the can be said again.

Man I would love to see you both at a studio recording and debating.
I have spent a lot of time recording, but not a lot of time engineering. That is an art all unto itself. And since I spent 25 years on stage with a Heavy Metal band, my ears a cooked
hence the reason I think so many of these boomboxes sound so good I have read that a typical Heavy Metal concert is louder than standing at the rear of a 747 during take off
WHAAAAAAT? WHAAAAAAAAAAAT? :hoveround:

Lol at least you got two ears to start with I only got one and its kinda starting to wear out lol. 25 years of metal yikes. I tell you tho a 747 is pretty loud . So is a top fuel car . With music tho its pretty crazy I mean standing in front of a stack of Marshalls is gonna take its toll. Better to burn out than fade away. I never had the patience to be a engineer or even for doing a good recording . I like it better when someone does that stuff for me. I've been singing a lot over the years I was away from here . It sounds so much better than my first early demos . I don't want to record myself anymore tho.....Lasonic TRC-920 said:Less debating and more "LETS DO IT!"

This is kinda cool. So my 2nd Gen 931 rumbles at 24hz, but picks up sound at 28hz, all the way up to 17khz. Or at least that's the range I can hear out of it. That's with 6 month old batteries, if that matters.fromNKLwithlove said:
My dogs ran over to it and had very confused looks.... hope their ears are okay.
If you want to see speakers really work, play an orchestral piece that really utilizes the pedals of a large pipe organ. The dt680 is the best box I've heard that plays really deep bass. It plays deep tones even better than the kaboom. At a certain frequency, the kaboom seems to roll off and not produce the low tones as forcefully as the dt680 does.

I went through this debate with certain 'know it alls' on this site & pushed a 20hz sine wave through my first 777 mod because some members claimed I was wasting my time with speakers since the blaster couldn't reproduce the notes effectively.
The 100Hz EQ setting is not an indicator of bass floor. 100Hz is the band center for BASS & 10Khz is the band center for Treble so it would make sense that a 3 or 5 or even 7 band EQ would have a 100Hz setting which would be almost the same a s a bass knob, slider....Kick drum/bass drum is tuned around 63 hz, bass guitar goes down to about 40Hz but mostly, bass from about 60Hz & up is about what you will get from most large blasters with stock speakers, while smaller 6.5" woofers like the M70 will go down to about 70-80hz.
