QTS = closed or vented? | diyAudio

https://www.diyaudio.com/community/threads/qts-closed-or-vented.2563/

Closed box : use speaker QTS in the 0.35-0.55 range, for QTC between 0.65 and 0.9. Vented Box : best QTS are around 0.27 - 0.35 for decently damped QB3 alignements. But, Dickason's LDC clouds this issue for me with it's quote of Small's EBP formulae. It suggests that you divide Fs by Qes and any values of 50 and under suggest closed while ...

Qts, what does it mean? | DiyMobileAudio.com Car Stereo Forum

The Efficiency Bandwidth Product (EBP) is a ratio of fs to qts. Ratios > 90 tend to favor vented apps Ratios < 40-50 tend to favor sealed apps Ratios between 40-90 can go either way Low qts woofers very often will exceed 90 for the EBP. A woofer with a low fs of 32hz, and a qts of .32 will have an EBP of 100. Raise the fs and this # only increases.

Does speaker Qts matter in door installations? | diyAudio

https://www.diyaudio.com/community/threads/does-speaker-qts-matter-in-door-installations.147247/

Having said all of that, I want to find out if today's generation of DIY drivers are more suitable to IB installations in car audio systems and if the speaker Qts is an indicator of suitability. Without test data, it seems to me that running a DIY 6.5" woofer in a door without crossing to a subwoofer could still result in a damaged driver.

Qts: The total Q of a woofer at Fs, considering all driver (speaker) resistances. Vas: Volume Acoustic Suspension. This is the volume of air having the same acoustic compliance ("stiffness") as the speaker's suspension. (measured in cubic feet or liters) Vab: Volume of air having the same acoustic compliance as the enclosure. Å: Compliance Ratio

12-13-2008, 01:34 AM. I have was given to believe a speaker with a Qts of above .4 works better in a sealed cabinet. Well, I was flipping thru the PE catalog Woofer Selection Guide and came across the Morel 9" CAW938 which has a Qts of .6. The guide states that in a sealed enclosure of 1.73 ft^3 it yields an f3 of 43 hz, while in a vented ...
