Does the Triton Two roll off bass below 25Hz? I have my Harman Kardon AVR 630 set to Large for the front, and the LFE set to Global + Front/Right. When I play certain msuci that I know have content in the 16-25Hz range, my two Velodyne subs, which are connected to the LFE out on my receiver, audibly and visibly play down to 5 Hz. The Triton Two's appear to produce virtually nothing below 15Hz, and have some content from 15-20Hz.

Do the TTs have a filter or roll-off at the low end, or is my AVR not truly doing full range? I could test this myself by plugging in the LFE to the TTs, but I thought I would ask the experts here (that's you, Mod .

And just in case someone brings it up, yes - I can hear and feel 16Hz, and for some movies, I can feel even below that.

Well, Global+ Front/Right sounds wrong to me, but I don't really know what that is ... if your subs play on 2.0 music than you are doubling up bass and LFE and it is not a true "Large Fronts, Sub Yes" bass management scenario. So, I cannot comment on what you are hearing or why.

Regarding the Triton Twos, this is a $3000 pair of VERY full range speakers, not a $3000 subwoofer. I have measured Triton Twos in my listening room FLAT to about 24Hz (using measurement levels of about 85dB). That's more full range response than I have measured on any other full range loudspeaker I have ever had in my listening room (and I've had a bunch, some that were REAL expensive). If you want high output, sub-20Hz bass, you need some big-ass expensive subwoofers for that purpose. Something like our upcoming SuperSub XXL, which is only $2000.

Movie bass content (LFE) can extend to 10Hz, but unless you are super-hearing, anything below 20 Hz is "feel" only. If you want that kind of extension it is not going to come from a full range tower speaker - even the mighty Triton One will not produce bone-crunching levels below 20 Hz. That's why you can buy $10,000+ subwoofers, because producing significant output at those frequencies is very difficult to do, especially in a consumer product. For reference, most bass that people hear and appreciate is between 30 and 80 Hz, which is why all the powered Tritons make wonderful home theater speakers, with their dual subwoofers, that will satisfy 99.9% of home theater enthusiasts' bass "wishes".

No doubt the Twos are excellent full range loudspeakers. Flat to 24Hz is excellent...

That said, I swapped the TTs for a SuperSat 50 and played the same content. At 10Hz, the woofers were visibly moving back and forth with about 1/4" of one-way excursion. So it seems to me that there is a filter on the low octaves setup on the amplifier section on the TTs.

With regard to my receiver, it turns out that "Global" means that all inputs are set the same way. I have LFE plus full range for the front left/right speakers, so yes, I'm doubling up on bass. In effect, I have 4 subwoofers, but the levels are adjusted so that bass is flat to about 25Hz.

I'll have to wait for the measurement on that XXL Sub to see how low it really goes, because like the TTs showing 16-35kHz, the XXL specs show 10Hz, which is probably not true.

I will check with engineering but I don't believe there's any filter on the active section of the speaker, although I am sure it does not pass DC so obviously something is done to limit low frequencies in the single digits. Not sure what the purpose of this conversation is, however, since woofers that move at 10Hz and don't have any output is meaningless in terms of audio performance.

Regarding specs:

1) I sure hope you didn't foolishly buy the speakers because of the specs, but rather because of how they sounded;

2) 16 Hz is a -10dB in-room spec, and it is correct. If you want to post on this forum you are going to have to refrain from comments like "which is probably not true.". If Sandy could do it the way he really wanted, there would be no specs on the speakers besides weight and dimensions, since those are the only ones that have any meaning, all the "measured" specs do is mislead people into incorrect buying decisions.

1) Agreed.

2.) If 16Hz is -10dB, that to me is quite acceptable, even pretty damned impressive. But I'm certainly not getting anywhere near that. What I'm getting is nothing at all at 16Hz from the TTs - effectively -80dB. So not sure what's going on. I haven't yet plugged in the LFE as a test.

I'll retract the "not true" comment I made. Just because I'm not seeing it doesn't mean it's not there.

Great, thanks, much appreciated.

Just curious, how exactly are you measuring these 16 Hz frequencies? The ubiquitous Radio Shack SPL meter is so far down at 20 Hz any readings below that would be random anyway. Phone SPL meter apps that use the phones mic have no response down there. Even my home high end calibrated microphone speaker measuring system does not report back frequencies below 20 Hz. The only systems I have been privy to that can measure that deep are professional measuring systems used in large anechoic chambers (or outdoors). Our bass extension specs come from measurements in our NRC-replica anechoic chamber, extrapolated for room gain.
