  1. REW Forum
    Hello! I would like to ask if we can measure with REW or calculate or estimate using the already found parameters, the following parameters for romm acoustics: STI (Speech Transmission Index) C80 (Clarity G (Strenth factor) Thank you! Stamatia

    Hi, To accurately simulate the frequency response of a vented-box loudspeaker system, we need to know some "hard to find parameters" which are the Q losses (port, leakage and absorption losses) and the apparent volume of the enclosure (the one used to compute the box compliance). REW allows to...

    Hello. I've been using REW for room measurement for some time, and now want to use it to measure some drivers towards designing speakers. I've gone through the Help section "Impedance Measurement" and still have some questions. Probably the first one to get going is the 100 ohm resistor to be...

    Are there any tutorials available for using the Thiele-Small parameter calculator? A search of this thread for Thiele-Small' and 'Thiele' brings no results for instruction, just issues with the calculator. Lots of between the lines questions to be answered. Example: I see the diagram in the...

    When using REW to create T/S parameters it generates two inductance models. The first model is the FDD Electrical Model. To the best of my limited knowledge there is no enthusiast level enclosure modeling software that can use this model. The second model is called the Simplified Model. I...

    I am wondering if it is possible to analyze (Ra-)Sti parameters by using REW. I was attended for an update. I thought it might be usefull regarding this subject, but I couldn't find a proper download option. All the best,

    I want to use REW to measure driver's TS parameters and Basta! to do box design. Basta! requires voice coil inductance, Le (mH), filled in its Driver tab. Should I use Le(f3) generated by REW? Or Le given in Simplified Model Parameters? Many Thanks!

    In the instructions for posting a REW graph thread I see this: The preferred axis for ALL subwoofer graphs is: VERTICAL = 45dB-105dB HORIZONTAL = 15Hz-200Hz. The preferred axis for full range graphs is: VERTICAL = 45dB-105dB HORIZONTAL = 15Hz-25,000Hz. Could some walk me through setting...

    Hi Everyone, I haven't been able to find an answer to this, so I thought I'd ask. I've loaded some filters into my BFD 1124P via REW's MIDI interface. The filters are loaded, but somehow or another when I did a save of the filter settings using REW, I got a blank .req file. :sweat: Can...

    I know there has been the occasional thread on being able to upload exported filter settings from REW to JRiver. Has anyone been successful with that?
  11. REW Forum
    Hi I browse the forum for more information about the hardware preparing, making for the impedance measurements and TS parameters. . I didnt find anything exact and specific i must say very few diagrams and every one is incomplete or unclear? . I tryed to find in help some diagram without...

    What driver parameters should I be looking for to maximize performance in a sealed sub? I'm particularly interested in 15" drivers in a 3.0 or 3.5 cu ft. sealed box. I understand that some drivers work better than others, so I'm interested in understanding why. Thanks!

    Hi Guys Just joined today and was quite interested in the capabilty or REW to measure TS parameters.Has anyone tried this and would be able share the steps needed.Understand that normally would require a resistor would be required.Thanks so much!

    I just wanted to compare DSP1124p and DCX2496, setting up a DCX2496 eq with the same measurement, but the REW eq parameters aren't the same as in the DCX2496, this could be verified in the remote software for the DCX2496... There could be a reason for this though ? John ? Thanks Klaus

    I've been trying to load the parameters for the Dayton RSS315HA-8 but not having success. I enter the T/s Parameters and the physical dimensions but I get an inconsistency error. I'm entering the proper values but WinISD Pro won't allow me to save them. I'm trying to model a slot vented box...

    I was going to do a 12" TC Sounds Epic or T1000. But I just bought a 15" Cascade Designs Omega from my buddy for cheap. The only thing is I can't find there website and don't have parameters. Can anybody help me on this... Or am I on my own LOL. thank you for your help.

    I was hopeing sombody could post the exact parameters i need for a driver in order to calculate box size. I've got the WT3 woofer tester and just not sure if it's giveing me all the info i need. Thanks in advance.:dontknow:

    I bought one of these and I would like to have the T/S Parameters if anybody can post them. Single voice coil (2009) 1st generation Maelstrom-X 18". Thanks Mike

    I've got some older drivers that i'd like to build some towers with and the only thing i know about them is they are MB Quart 4ohm car audio drivers. Parts express has a measuring tool on sale this month, The Dayton audio WT3 woofer tester. I was wondering if anyone could tell me if this would...

    Does anyone know what the TS parameters are for the FI Q18s with the BP upgrade and if it differs to the ones on the website. cheers Graham
