  1. New CEA 2010 in room Measurements.

    I have been doing most of the commercial subs in my room as well for quite a while. Mostly as a data point on the room acoustics effects I have and how distortion is lowered in the deep bass. Mic is at head position at the main seat and subs are placed in the same corner each time. Only valid for my room and that exact placement.
  2. (8) Ported Incriminator Audio Judge 21" build

    Finally! I bet you will be glad to have this project off of your plate and be able to fire up all 8.

    It should be fine. Response shape may be a hair different but not a deal killer by any means
  4. That is good to hear Nick. I decided not to see that in the theater so I could fist watch it at home. Looks like it has some good 12 to 25Hz energy. My buddy also said the visuals are stunning.
  5. New SVS Ultra 16"

    Looks like it is time to try that K20 out on the next big woofer across the bench. Judging by the slope of those curves it looks like the 70% BL point is going to be around 20mm.
  6. The Bass EQ for Movies Thread

    John how much time does it take you to go through the process above?
  7. New SVS Ultra 16"

    I went back and looked at the Tymphany STW-350F specs and they are totally different from the specs that ITR posted from a PB16 driver. Originally I thought that these drivers would be quite similar or were at least using a similar build platform. After looking again there is very little similar between them at all. The frames are different, the STW-350 is 15" OD but the SVS appears to be 16" OD. The STW-350 is using an overhung topology with a 7.4" diameter coil. SVS says they are using an underhung 8" nominal diameter. That being the case both the surrounds and spiders would be different. The overall motor / gap / coil geometry would be much different as well. In fact it seems like perhaps the only parts shared would maybe be the motor case and backplate. Although the motor outwardly makes the drivers seem like close brothers it appears that they are more like estranged 3rd cousins. Modeling the 2 drivers using the parameters provided shows that they behave as differently as you would expect. The SB16 driver should be a completely different 3rd driver design. I must say this has gotten me interested in testing the SVS 16's again.
  8. New SVS Ultra 16"

    Thanks. They are not what I expected. I just checked and this would've tied the 21Ipal as having the stiffest suspension I've ever encountered.
  9. New SVS Ultra 16"

    Welcome to the forum... Just to clarify...These specs are pulled from what driver? What jumps out at me is Qts = 0.87 BL^2/Re = 118 n0 0.186% Cms=0.039 Extremely tight suspension + 500g mms and a relatively low strength coil / motor system results in a very inefficient driver. Very odd set of design tradeoffs IMHO.
  10. JTR Noesis 215RT Measurements Discussion

    Kinda off topic from the 215RT... In general if I was selling subs or speakers I'd probably aim for a flattish response to 30-35Hz and a gentle 6 to 12dB/oct roll off below there. Rooms vary a LOT but if you look at the broad trends vs individual samples most rooms seem to have some moderate boost by 20-25Hz and a large amount by 10Hz. Mine has about 3.5dB at 20Hz and about 14dB by 10Hz. There are always those examples that don't and you have your usual room issues such as the dip in the 12-17Hz range that occurs in a lot of rooms, or the peak near 40-60Hz for seating placed near the center of the room. A lot of companies go for the flat full or half space bass response. It's really a matter of preference and design choices.
  11. FV25HP measurements are viewable now.
  12. FV18 results posted...
  13. Do you have Alpine? How much is a SWS-15d2 or an SWR-1522D? $400 is a lot for a UM18.
  14. How much is an Ultimax in Belgium? How much is a 21" B&C? I'm just curious. There may be other driver options that make more sense given his location.
