Hi,
In this case my strong preference are the F15 mainly due the gorgeous range performance from 100 to 400Hz where a big cone shine, not to mention the bass under 100Hz in the suited BR box.

I could suggest the Lii suited box(290L) with 1 or 2 round BR ducts or even better a bigger one.

@nature boy 

Thank you for your comment.

I'll keep that in mind for the F15, thank you. What you're saying means you've confirmed this design, right?

So what would it be like if a bf was designed with crystal 10 and W-15?

I have not listened this Lii box but since you have no space for a OB panel this project seems suited to you. My first option always could be a OB for the over 200-300Hz, but for bass I could prefer a hi efficiency woofer as Eminence Kappa 3015 in a 180L BR box, the Lii woofer seems anemic 91dB and expensive.

The Lii 10'' and W15 in the same box will not work due different efficiency 91/99dB not to mention comb filter effect.

[Newbiee]

Would you recommend crystal 10 for open baffles?

"The Lii 10'' and W15 in the same box will not work due different efficiency 91/99dB not to mention comb filter effect."

Is sensitivity as important as bf in the Open baffle project? I think the sensitivity of crystal 10 has been reduced to w15 in this project.

"The Lii woofer seems anemic 91dB and expensive."

Why is Leon insistent on using w15? Is just sensitivity and power the point to look at when choosing a woofer?(when combining with these full range drivers) Sound characteristic etc?


Edit: I've learned this information, i don't know how accurate it is, but does it change anything?

W-15:
2.83V: 91.3dB (single voice coil)
2.83V: 95.6 dB (dual voice coil)

It's best to look at w-15 frequency analysis.


KAPPALITE 3015
Isn't performance in this area more important? Serious drop from 100hz to 50hz.

Many questions, tô connect two drivers without xover correction the VC have tô be idêntical.

Só upon this If your amp work well I 4 ohms you could connect 2 F15 in parallel.

One for bass in a BR box, other tô OB over 200Hz.

Yes there were too many questions, sorry. Now I know what I want. All I want to know is whether the woofer you show as an example is the best option to match the crystal in this brand. If I want to build a cabinet with two speakers (crystal + woofer), what should the cabinet dimensions be? Thank you for giving a time.

This Eminênce Woofer is my personal favorite what may not be your taste.

I have a 180L BR project I can pm you tommoroW.

[FullRangeMan]

For the Eminence I prefer a 180L slanted BR box.

[FullRangeMan]

The 10"" cone are só Light that the Woofer bass will distúrb the 10 cone movement, both in the same box are not recommended.

I'm receiving my Lii F15 OP speakers today from Randy!!!! Man it's been a heck of a month waiting but I'm stoked 

Sorry, "Now back to your regular scheduled program"

[Budget_Mike]

Cancel that, UPS just notified me that it will be delayed for an additional day.

[Sandals123]

I suggest getting some extra sleep today and tonight because once you get you speakers from Randy, you can bet that you will have a few late nights of re-listening to your library of music and shaking your head at all the "music" you will hear.

I am so ready for that, had my afternoon cleared today for it but alas I moved some things around to clear it for tomorrow.

Music will be playing non-stop... Send help

Here is a photo of my setup. Triode Labs SET 2A3 amp with a whooping 3.5watt drives them perfectly!

[goggle1824]

Woo!

[FullRangeMan]

Newbiee,
This is a project I made for this Eminence woofer:
Bass Reflex Slanted golden ratio 1 woofer only,
so you wont need braces, it may be slightly above average volume recommended, if possible use only 1 duct.
W 50cm
D 30cm top
D 50cm bot
H 80cm
Vol 160L

UPDATE: DELIVERED!
I will absolutely be sharing my setup once everything is dialed in and placed neatly. Now I just have to convince myself not to walk out of work right now and go hook them up.

Thank you fullrange. By the way, Lii's new 18 inch driver appeared.

but but but...... I just got the 15's 

[Newbiee]

Too ambitious for full range. It makes me wonder what an 18-inch driver would be like in mid sound.

[goggle1824]

Those drivers aren’t even up on their website yet. Bleeding edge catch there!
