JBL Xtreme 2 - LFM ON vs OFF

Speaker excursion demo of this JBL Xtreme 2. Helps if you have headphones when you watch this type of video. The previous video has sound quality as well as bass tests.
I'm not at max volume when testing it with DSP off ("LFM" on), you pretty much run the risk of causing damage to the speakers or possible the amplifier that way.

[@tkermi]

@@supersolex How do you mean "no"? In many amp desigs you get somewhat higher "B+" voltage when plugged to the charger/PSU. If the batteries are full, large enough and voltage doesn't sag with high output transients then the difference could be quite small though (only below +5% power). But in some designs where wall PSU can bypass the internal BMS you could get noticeably boost. Like rail voltage of 12,5V with full batteries and 15V with wall PSU. That's 44% more power. But I don't know how common this type of a circuit is though.

I have been using "LFM" since I got the speaker, it was the main selling point for me. I've ran many songs through it from xclsvs channel and haven't had any difference. I have two of the same speakers (Xtreme) and both sound identical. The only difference so far is on "LFM" the battery dies faster obviously because it's running more power, without it on it still lasts well over 10 hours of constant use. It hasn't blew any drivers, the radiators are still fine and tweeters working perfectly. I get that it can break them but geez calm down a little I've had mine for well over 5 years now...

@@tkermi They should have just made 2 prestets: the standard one and one that doesn't have the highpass (but still has all the other good stuff)

[@KittyKite]

@@buka9330 highpass? what.

[@tkermi]

@@buka9330 It could be nice to have more presets, yes. Typically you would like to get some bass boost when listening at lower volumes (to get balanced sound). But some modern DSP curves already include "dynamic" feature to cover this without the need for different preset. I would have to listen this "LFM mode" in person to know if I would prefer the option to not have a high-pass filter of some sort. With sealed cabinets this is not a problem but with reflex loaded cabinets the cabinet volume, passive radiator and drives together determin the bass properties near and below the tuning frequency. So just having the drivers move at the lower than tuning frequency doesn't mean there is any practical output (acoustic short circuit + phase difference cancellation). To get a real "LFM" option/preset in addition to the no HP (or lower HP) you would need to attach additional weights to the passive radiators. This would work up to a point but would limit the max. output volume and possibly result somewhat worse transient performance in upper bass frequencies. I have used this in my speaker designs and you can do the same by making reflex port longer. But it's all about balance - more is not always better.

[@tkermi]

@@KittyKite Yes, as a standard most BT speakers (actually most active speakers, even Genelec pro monitors) have a high-pass to get the maximum performance from a Helmholtz resonance tuned system (meaning a reflex tube or a passive radiator tuned system).
