Ben Harper bass notes hard on my speakers.

Hi all, My system hits low notes without any strain and sounds quite good. Luxman R-113 pre amp with a NEC A-910 amp pushing a set of DCM TF-600s. The CD Burn to Shine by Ben Harper really taxes my speakers to the point of rattle/Fart when I turn it up slightly and play the first two songs on the Album. Alone and The Woman in You. Anyone else have certain tracks that their system doesn't quite handle or familiar with these songs played on your own system? I just can't duplicate this flaw with any other tracks that I have listened to.Thanks for listening!

.most times unless you’re using very low power only speakers,
It’s usually the amplifier that can’t meet the demands that the unlimited Bass track
Is demanding, causing the amp to distort and “clip”. This is also what kills the tweeters.
I don’t know the equipment you have, but even a 125 watt Amp will clip unless it’s designed with a big enough power supply for the needed Headroom
Somehow I don’t believe it’s your speakers

NEC A-910 100 wpc conservitively rated. plenty of power. I was thinking maybe the notes are slightly lower than my speakers Frequency is rated which is 33 hz.
 
If the woofer is running out of its excursion distance it will make a strange noise and probably do some damage eventually...
 
It's not really possible to diagnose what is happening just by your description. Either the amplifier or the speakers are hitting their limit. What sort of cone movement are you seeing? It sounds sort of like you might be hitting the limits of the woofer's suspension. The foam and/or spider might be hitting it's limits. The voice-coil might actually be hitting something due to exceeding XMech. From what I can see these use 6.5" woofers. It takes a lot of cone movement for a cone that size to try to recreate frequencies near the bottom of the audible spectrum.

I would have to take the sock off to see the movement. Their is a coax shield mounted in front of the woofer that a tweeter is mounted to. If my 33hz speakers are being sent a 25hz signal from a low B string on a Bass Guitar would it have an adverse farting sound affect on them? I listen to a ton of music Loud with no issues what so ever. Just these two songs have me baffled.

Either way it can't be good for the speakers. they could be already damaged.

So I guess I can just not Listen to these two songs and my issue is solved. Like I said I can't duplicate this with any other song and I do push it loud and clean without it breaking a sweat on any other song I've played.
 
I looked it up that amp is only 100 Watts per channel. I have no idea what the speakers are rated for.
 
Try another copy of the cuts that are giving you trouble? I've had a few digital downloads go south on me, and the solution was to try another source.

Another potential solution. I'd go with some eq first, and try to tame whatever frequency your speakers are objecting to.

Good stuff - was just listening to Get Up! That will also push your system as they tend to go fat on the bottom. There again, solution was a good DSP EQ ...

PS ... got any Norah Jones? Her Come Away With Me drove me to distraction with over-driven bass. Tuned the system and she's good to go now.
 
Anyone care to give these two songs a good work out and get back to me with the results? No subwoofer utilized.

Yes, I have a Pioneer GR-777 that is utilized in my system. I can tame it out but I like to set it and forget it.

That's a ten band, right? Not a fan of any graphic EQ ... try to fix one specific frequency, and it will drag a whole bunch of the GOOD stuff along with it, causing more problems than it fixes. I eventually went with a parametric EQ here (Technics SH9010) that allows you to dial in closer, but the real solution was software, using REW to get some readings and create a working curve, then loading that to jRiver's "convolution kernel" to get the results to the speakers, at least for all my digital stuff (which is most everything anymore). Not too expensive and a bit of a learning curve, but worth the effort - I haven't touched a tone control since, no matter what I throw at it.

I still use the SH9010 for my analog sources, and was able to fine tune that substantially using the REW curve printout and concentrating on the big lumps.
 
Radiohead - Amnesiac, track 1. Does it do it?

That track is the track that my Sansui 9090 couldn't handle into my magnepans. Clipped badly and sounded like a rattle.

Ten band is correct. I have it set mostly flat. Slight 1 db bump at 63hz and 4 and 8 Khz.

Speakers are rated at 250 watts program peak and are fairly efficient. The NEC is more than capable of driving them. 6 ohm speakers so the NEC is probably pumping a good clean 125wpc.
 
I just played both those Ben Harper tracks you’re having issues with obnoxiously loud and zero issues here . I’m running Vandersteen 3a Signatures with a factory upgraded Musical Fidelity NuVista M3 at 305wpc .

edit: I had my sub off as well.
