Hello guys,
I have 2 pairs of 15 delta Lfa, there's someone ever tested them in a horn kick bins? 90hz to 250hz?, it is worth a try or better to go for reflex?
I'm not familiar with any simulators that's why I'm asking.
Any help it really appreciated 😊
Thank you and regards.

Its a decent cheap driver that works well in a larger ported box or sealed, but it wont quite make it up to 250 in a FLH based on the specs alone (2 × 39) / 0.52 = 159 Hz. IMO this driver works best as a midbass in a sealed box and sounds pretty punchy. Problem is the power handling won't be great being in a sealed box, not getting much fresh air flow into the VC, which only measures 2.5 inches, so not much forgiveness in the power handling department, not to mention personally not having much luck with longevity with most eminence drivers using this VC format. Really depends on what performance and output you're expecting from it.
Thank you for your reply, yes you have reason it's very difficult to go up to 250hz in a FLH. My subs are 18 hybrid horns and my tops are 12s(normal 2way). I think i'm missing that punch at 100 to 150hz. My subs only sound decent till 110-120hz and the top are not giving that desired punch.the worst case scenario i built a cubo kick and try the LFA in it to know how it sounds.
The LFA wouldn't be my first choice to use in a horn or resonant enclosure but it is worth trying in a simulator. Do you have the specs of the horn?
Thank you for your reply. I was thinking to try the cubo kick that is found in freespeakeplan.
this some info that I fund online maybe may help. the width of the box is 68cm and built with 18mm.
Anyway, moving right along........this kick bin only really loads ~ an octave (~90 - 180 Hz), then shelves down ~6 dB down to ~250 Hz, so for 90 - 250 Hz 'flat' will require EQing, though of course will still have an extra +6 dB dynamic headroom in the bottom octave if needed for some apps, otherwise have ~ 100 dB eff. from ~70 - 700+ Hz vs the driver's ~95 dB mid-band eff.; or EQ the whole BW to 'taste'. 😉

Hey there, just wanted to offer input on the cubo kick bin.
Works as intended, covering the 80-160 region very well (have built two of them for PA apps), the sharp rolloff on the top end helps a lot with harmonic distortion, although I'm not sure for home use that would be a concern. Additionally the ports can be blocked for greater flexibility with the high pass function of the cab, I'm sure you could overload them easily with 1 or two ports open, but again not an issue with home use imo.
Gm has a good approximation of the data with his hornresp Sim, although I will note for the sake of accuracy that it is in fact an offset horn and as such has the corresponding qw notch around 200hz or so - I can't remember exactly where it is, it's been a while since I've looked at the Sims/measurements. Just keep that in mind if you're looking at a high xo point (above the the primary bandwidth of 80-160), as it will introduce phase shift/inversion, which will mess up most xo's.

They are not for home use, I'm building a small pa. The LFA's are coming from a pair of dual 15s full range cabs that i don't see any use from them which they are very heavy and unattractive.
Thank you guys for your quick and efficient response i really appreciate 🙏
