  • Dayton 12 inch


    Has anyone done listening comparisons with the following Dayton 12 Woofers?
    TIT320C-4
    RSS315HF-4
    RSS315HO-4

    It appears that the TIT320C-4 has a strong following and a higher price that the other two, but some of the parameters and construction characteristics of the others seem superior. It would appear that the final decision would be a listening test. So, I wonder ... has anyone has had the experience?

    A listening comparison would be difficult since your hearing largely depends upon timber making assessments of a single frequency range difficult (although in your mind you believe you are focusing on a given frequency range the reality is different).

    The reference series drivers are designed for low distortion and have three Faraday rings in their motor.

    The HF version of the RS line has a two layer voice coil and it's ratio Re/Le is nearly 3500 while the HO version has a four layer coil with the ratio Re/Le being nearly 2000.

    The HO version has a higher Mms which means you can achieve a given system resonance in a smaller box which will require more power for full output and higher distortion due to the four layer coil modulating the magnet systems flux to greater degree, greater hysteresis from the steel in the motor and greater position dependant modulation of voice coil impedance.

    The Titanic on the other hand is designed for high output and it's rated Xmax is nearly 19mm where the RS series rated Xmax is 14mm and 12mm.

    The Titanic does have a Faraday ring but it is located in an area where it can't help much.

    The Titanics ratio Re/Le is less than 1000 which means the response will want to peak above Ftc and then fall at higher frequencies which means the Titanic can only be used a subwoofer where the RS could be used as woofers also.

    Standard box software calculation won't predict the box response of the Titanics very well but will for the RS's since their Le is so low.

      also your thoughts for a driver serving 120hz and below for LFE duty? Probably the same driver?

      big thanks for your expertise. Tony

        Why are you tagging on to a 14 year old zombie thread? The answer to your question is you software model it. That's how you see the capabilities of any low frequency driver.

          As daryl said, the HF series has very low inductance, so 120Hz should not be a problem. As Bill said, modeling software is your friend to see the LF response. I'd guess it will do fine below 45Hz.

              Here are bone-simple calculators:

              WinISD is better but needs a little more effort.
