Best size box for Dayton Audio RSS265HF-4 10" Reference HF

...Terminus on driver side....my first thought really... I would use this outside mostly, so port on driver side would be best...

Outside?..Hm..Maybe a ML-TL would be a better choice if to avoid a BR with a tall ringing port?

FWIW:Here's a real bad CAR? BR example to be avoided that show severe ringing if not the entire box and the port partly(effectively ~47")are stuffed.

I didn't posted this to a thread a few weeks ago as there was to many wacky comments on why a very similar box didn't perform well..

Isn't that ringing occuring way above the passband that car audio subwoofers are normally used in? They're typically cut off @80 Hz, if not lower.

You're right In a car the ringing is near blameless levels and would in most noisy cabins be masked but if in a quiet room with a picky listener, (Me of course ):

The ringing would be recognized as when XO:d at ~80 Hz(I prefer lower) this ringing is ~20 mS to long (~43 mS = ~15m) is where I set my 'Distance cue arrays to JND and I do not like attention(amplitudes at higher levels but less than ~105 dB) from a sub that pops out and tilts my central phantom spread more than necessarily.

Remember that the ringing(coloring) would be outside of BER 1,thus extremely easy to be heard when long in lime.

Ok so... I think I'm going with one of these 3 boxes for ease. Question is, should I port or not :/

It's advertised for sealed or ported. I did run it in WinISD and it recommend a sealed box slightly less than 1cf.

At this point I think you have to determine the Qtc (sealed box) for the room you want to put it in (way over my head).

Hi,

IMO, The closed box is OK but the ported box would have port severe issues.
A TL would be a much better performer when placed at floor level, near a room corner.

Hi, In that picture: All calculations are using Mathcad and the simulations are MJK:s quarter-wave Transmission-Line programs.Visit:
