Kaj, also check out 'Jurassic Lunch', early on in the topic. Several heavy material is there where you'd loose half the impact when your sub cannot go below 20Hz. The final sound, when the dinosaur hits the floor, is an example of that.
@Jeff-0: Thanx for the explanation, and you're right that it is best to use the same parts, but without listening to them ourselves and comparing to other solutions it will be hard to form a definite opinion. ;) And can this ZERO-KNOWLEDGE inflation, trolling and people bashing stop? Repeat...
How do you know? ??? Do many owners complain about bad allignment, or are you considering them all incapable of recognizing bad sounding speakers with out-of-phase mid-range drivers? I am considering buying 750's myself, and am anxious to see properly measured speakers - preferably retail...
Mark L. Shifter stated that these speakers were sent for a photo-shoot nothing more, AFTER the review had been gone and done. He's in contact with Thomas J. Norton to see if they can redo the measurements on Speakers that actually went through proper quality control. (link) B.t.w.: these...
It might depend on how many particular adjustments have to be made, but I for one am extremely happy with such a tool - with both music and movies. Listen to a frequency sweep to hear if the difference between having one and having to do without is big enough for you.
What you show here is nothing new or dramatic, it is precisely how accoustics work in a given environment. Room-treatment might help you out, or less concern about creating 'ideal' listening conditions at two different locations. I would suggest either treating your room (bass-traps, etc), or...
If your Speakers and Amp perform like before chances are nothing is damaged. From my experience tweeters run the most risk when an Amp is run beyond its limits, because clipping introduces extremely loud high frequency harmonics. Tweeters are typically not built to handle tens of Watts of...
I have Pioneer (AX10) and BFD as well, as has been said: First flatten response with right sub placement and the BFD, then let the Pioneer adjust level and distance. I am -extremely- happy with the results I get.
If you read more carefully you see I was talking about lower bass, not some pink noise signal. In the 20Hz - 30Hz region the SPL at (almost) any location in the room has little to do with distance to the sub, and all with room nodes and such. -- Yesterday evening my DTS copy arrived of 'Sky...
For lower bass the sound you hear is the sum of many reflections, not the sound that reaches you directly (unless you put your head inside the sub :D). It is higher harmonics that makes bass sound snappy and gives it direction. There are many places with interesting reads about this subject on...
Using mass underneath and (in some cases) on top of a sub can seriously improve sound quality. You should also isolate the slab underneath from the floor by some means. I use cut-in-half squashballs, very cheap to come by (if slightly used).
I disagree, unless you were talking about huge sound stages or listening outside. In real-world rooms it is the size of your listening environment that determines how much energy it takes to reach a certain SPL at low bass frequencies. That, and of course the position because of local...
"16-46PCI is +10dB at 15Hz(!)" Whow! At best I can make it flat at 15Hz, with both port plugs fitted. I guess you really didn't need to buy the 16-46 sub, and could have gone for a more 'mainstream' SVS. :)
In rooms around 30-40 feet you will experience huge gain in the 14-19Hz region with corner placement, ideal for subs like my PB12-Ultra/2 with zero or one port plugs. Currently I have it placed near the "virtual center" of my 16x16 room - with open kitchen, to prevent all the unwanted gain...
I would still not recommend using > +6dB gain in any frequency range. --- My current settings were done through playing 20 or so "Warbles", using my DEQ2496 as an SPL-meter. In stead of needing 7+ 'sophisticated' filters using SpectraRTA, I ended up using only 4 (easy) ones. The result is...
I have a similar question: Living in a very solid concrete building seems a huge disadvantage in experiencing "chest (?) impact". So much so that I am considering buying a buttkicker to "shake the couch/ (elevated) floor" by some other means. The question being: Is my view correct, or are all...
Using a heavy slab of stone on several squashball halves covered by some carpetry has worked wonders for my PB12-Ultra/2. I used 14 squashball halves for the heavy (190lbs) sub. Solutions may vary depending on needs, but ideally you'd want a big mass to absorb the vibrations - isolated from the...
Dustin B, are you saying that two cheap Avalanches in a 5-6 ft^3 sealed enclosure could equal (or better) the performance by a PB12-Plus/2 or a PB12-Ultra/2?
MingL, about the Incredibles: the rocket launch in the volcano is probably the most impressive of the lot. I have yet to find a scene in ANY movie to top that one SPL-wise, really. ;)
