Woofer placement in box rearding the floor

[jawen]

Have build a 91 liter netto box for my Dayton RSS390ho.
The cut out is cc 23 cm from box-ending on one side, and cc 43 cm from box-ending on the other side.
I want to mount 4 legs 25 mm in hight, but don´t drill at the "wrong side" in my Walnut imitation. (which I worked with for 3 days)

Is the lower montage "better" for "bass-support" regarding "floor-helping"?
It´s a 15 inch sidemounted xcrossed at 150 hz, and 2400 hz and going to be used as a 3 way.

Then speaker placement in stereo, play inwards towards each other or outwards in each direction?

Best regards John

You're only now deciding on this?? Protect the woofer from errant vacuum cleaner with some height.

Normally, crossing at 150Hz is sufficient for 'it doesn't give a s&%#! where that woofa's gonna hang out'. Reinforcement from nearby boundaries at 150Hz is effective up to 1,5m distance between woofer and boundary. At 40Hz you can make that 5,7m.

No, I have thought about this from the beginning of the project, but in the design there is also a cosmetic aspect for me.
It looks "better" with the woofer diver higher up in the box, but I would still choose "closer to the floor" IF it was better from a sound perspective.

Reinforcement from nearby boundaries at 150Hz is effective up to 1,5m distance between woofer and boundary. At 40Hz you can make that 5,7m.

So you mean I don't "lose" anything by having the woofer driver cc 43 cm from the floor, insteed of cc 23 from the floor?

Correct. Somewhat higher up could even be slightly beneficial, because it does excite the first few vertical room modes a little less.
