Lii Audio Fast 8 Is supposed to be very good. Did you you use the eminence delta as well?
I am just unsure as to how these compare with the full bodied sound of the LX521 which uses vastly more expensive seas drivers. I’m not sure if these single driver designs will sound too clinical (chi-fi) / lack dynamics? Cube audio is supposed to be a step ahead, that’s why I ask.
No, my woofers are Hawthorne Audio Augie 15's.
I bought both the Augie's and Fostex FR as NOS from members here, projects that never came about, I think. I didn't know how the speakers were going to turn out and I didn't want to spend too much on the components.
Papa's design turned out much better than I expected. At first, I used an old op-amp based crossover. When I changed to the ACN LX Mini crossover I noticed a large change, same again when I switched to the Fast 8. If I had to buy new woofers, I'd buy the Lii Audio 15s.
I liked these speakers so much I sold the pair of upgraded Zu Audio Druids, that were my normal listen. These are more lively and produce much more bass.

"The Cube Audio system I heard was decent, as far as single driver systems go, but it was a bit peaky and lacked bass. The ideal listening window is quite narrow with this speaker, but, that is also the case with most full-range drivers."
High Efficiency Speaker Asylum
Narrow listening window puts me off. I'll wait till I hear the voxativ before making judgement - perhaps I'll consider slot loaded woofer + 2 way open baffle in the same design format.

Rise... RISE, from slumber, ye thread! 
I too am wanting to try a higher WAF build like the SLOBs detailed in this thread. Have OB FRs over 18" H-Frames, per MJK now.
I read every post in this thread and was hoping it might have some sort of a conclusion... I like the principal of running two 15" drivers (one slot loaded, one front mounted) to possibly get away with not needing bass boost/EQ. Is this the ideal build or is the single 15" in a slot the way to go? Limited on budget but have some FRs I can recycle and kind of wanting to try the Lii Fast8 anyway.
And how do these parameters look?
Nominal Diameter15"
Power Handling (RMS)350 Watts
Power Handling (max)700 Watts
Impedance (Z)8 Ohms
Sensitivity93dB 2.83V/1m
Frequency Response30 to 6,000Hz
Voice Coil Diameter3"
DC Resistance (Re)7.4Ω
Voice Coil Inductance (Le)2.1mH
Resonant Frequency (Fs)28Hz
Mechanical Q (Qms)11.7
Electromagnetic Q (Qes)0.43
Total Q (Qts)0.41
Diaphragm Mass Inc. Airload (Mms)137g
Mechanical Compliance of Suspension (Cms)0.24mm/N
Surface Area of Cone (Sd)829.6cm²
BL Product (BL)20.2T·m
Compliance Equivalent Volume (Vas)8.55ft³
Maximum Linear Excursion (Xmax)7.8mm

Yup.
Here you can find the values calculated by WG45 and gently shared:

4 channels of ACA, N P told me how to mod the crossover for the drivers which are the awesome SAL ones we sold for awhile in the store. Woofer is Hawthorne Audio Augie 15” (made by Eminence) Both driver companies are out of business.
It’s a pretty large room, 9x10M, and the second photo show the way it connects with the kitchen. It’s a bit live, with rather a lot of hard surfaces.The OB radiation pattern helps a lot, as the tall ceiling is also reverberant. They sound spectacular, mostly because they aren’t close to any walls. The high’s and low’s are not super extended, no silbilence in the highs, no boom in the Bass…But the SAL tone just takes your breath away for the beauty of the notes!
Finally, a system that could still be tuned a bit (I have the PASS VFET amp kits to build) but I love it!

That’s what my wife said!
When we bought the house and I started on the remodel drawings, I mentioned that there would be speakers in the living area and she said “Well, I figured that’s always the deal with you”. One of those good women! That inspired me to have the tubes in the floor to hide speaker cables…um, real soon now!

Is it possible to sticky this thread and change title to Pass SLOB builders or similar? It would probably be useful for future builders... 🍻
