    SVS speaker stand `?'

    Then you're obviously not using REW. :) My wife finds REW sweeps hilarious and walks around going: "Wooooop!" Which might be considered entertaining but can play havoc with the response graphs. :D

    Discover Deep Bass

    Call it what you like, but what is special about using a 3 drivers @ 120 degree configuration when cancelling forces of opposing linear motors? Two opposed @ 180 degrees is surely as effectve as (say) 3 @ 120 degree, 4 @ 90 degree or any other combination adding up to 360 degrees. Three...

    Pictures up on new SVS SB-12 Plus: Quite Lovely in Rosenut!

    SVS rewrote the book on affordable reflex subs. Will SVS rewrite the book on affordable sealed subs? Watch this space! :)

    Discover Deep Bass

    I'd like to know what on earth the thread title has to do with this particular sub? ;)

    Router bit question

    If you ever get round to cutting holes for larger drivers then you can easily modify the router straight-cut fence without ever needing to buy a radius jig. I replaced the fence itself with a piece of scrap 1.5" x 1.5" x 1/8" light metal angle about 6" long. Which I fixed to the ends of the...

    Room size to match wavelength and bass quality?

    Thankyou Mark and to all who kindly responded to this thread. It's always nice to have some new facts to help to fill out the large grey areas in my knowledge. The more I learn the less I really seem to know. Regards ChrisBee

    Room size to match wavelength and bass quality?

    Doesn't large room gain match the gain for the same low frequencies without the hurdle of taming small room modes?

    Room size to match wavelength and bass quality?

    I don't know who this Nimby is but he'd not have much success sharing a room between an IB and a 16-46. I tried it myself. Fine on film but not on music. ;)

    Room size to match wavelength and bass quality?

    My futile attempts to blame small room effects as harmonic distortion may well have done the author an injustice. I think he was really suggesting the loss of the organ pipe fundamental was due to masking room modes. Falling human LF hearing sensitivity and falling LF output makes accurate...

    Room size to match wavelength and bass quality?

    I was seeking responses to an article I read online. My understanding is that the author suggests that those attempting to listen to organ music (using an IB) should have a room large enough to support the very long wavelengths involved. I believe he also suggested that stair wells were just...

    Room size to match wavelength and bass quality?

    Of course. If only we could arrange room gain to be spread over a usefully wide frequency band we could haul down the free house curve (and consequently the distortion within that band) with a BFD. This assumes that reducing the sub amp's input with a BFD equates to reduced distortion on the...

    Room size to match wavelength and bass quality?

    No. Of course I'm not suggesting the subwoofer itself is affected. Only its measured distortion performance in a particular room. My basic question keeps nagging me: Can a room affect subwoofer distortion levels depending only on the dimensions of that room? Your logic suggests that it...

    Room size to match wavelength and bass quality?

    Thankyou for your interesting responses. I was really trying to get at the difference in the bass sound quality between small room compression and a larger space able to support the half wave. My fuzzy logic suggests that a large room should offer better quality bass. (I'm not discussing...

    Soundsplinter RL-p15...port surface area?

    If you use PVC you will have the option of ready-made elbows (bends) to extend the port. These bends add considerable flexibility in box dimensions where long ports are necessary for a particular tune. Bends can be tight or slow and there are various angles available. With Sonotube ports you...

    Room size to match wavelength and bass quality?

    So there is no change in the waveform below the half-wave minimum boundary dimension? Is there no increase in harmonic distortion where a half wave cannot physically exist between boundaries? A skipping rope cannot reproduce a specific half wavelength where the distance between the rope...
