Ok, Here we will continue from where we left off from previous thread - Open source speaker project?.
First poll result was for a 3 way classic speaker (no horn), the budget is 500-1000$ for drivers only (excluding the crossover parts and cabinet).

EDIT 9-20-18 :
Tower XL discussions and development will be continued here :
Open Source "Tower XL"

The new poll is to set the goals for the selected design.
Poll options are pretty much self explanatory, please keep in mind that these numbers are not the final numbers and are flexible, but the poll result will set the goal for the design.
Please leave any questions you might have about the poll options.

Edit:
I had to shorten the options so it will fit the box:
1-Classic Look- Amp Friendly - High Sensitivity (92db+), Higher Bass Extension (f3 of 40-45Hz), Cabinet Size of 60-80 Liter.
2-Classic Look- Bass Friendly - Deep Bass Extension (f3 of 35-40Hz), Lower Sensitivity (~88-90db) , Cabinet Size of 80-110 Liter.
3-Classic Look XL- Amp and Bass Friendly - High Sensitivity (92db+), Deep Bass Extension (f3 of 35-40Hz), Cabinet size of 100-150 Liter.
4-Tower/Floor Standing- Amp Friendly - High Sensitivity (92db+), Higher Bass Extension (f3 of 40-45Hz), Cabinet Size of 60-80 Liter.
5-Tower/Floor Standing - Bass Friendly - Deep Bass Extension (f3 of 35-40Hz), Lower Sensitivity (~88-90db) , Cabinet Size of 80-110 Liter.
6-Tower/Floor Standing XL- Amp and Bass Friendly - High Sensitivity (92db+), Deep Bass Extension (f3 of 35-40Hz), Cabinet size of 100-150 Liter.

Wtf!
Because we've got to narrow it down, geez!
Why not a tiny desktop? Good lord!!
Why not a fullrange in a 40cu ft backloaded horn? My goodness!!


In all seriousness we've got to hone in on something that atleast a few people will build.
I love OB, but if you want an OB project at this point you need to start a new thread.

I have one question before I vote. What is the difference between the two xl options? It seems that once you get to a certain size the monkey coffin gets so big that the tweeter is at ear level. Is the woofer side mounted on the tower?

I cannot comment on the intention but my interpretation would be a tower is deep with a narrow baffle and possibly multiple woofers or woofers on the side. A classic cabinet would be shallow with a wide baffle and usually a single woofer. Something like Zaph's SB12.3 would be somewhere in the middle and difficult to categorise.

I voted before I got any feed back for the xl tower. I was thinking of Zaphs sb12.3 as a large tower. Any how I'm hoping for the largest woofer, largest box, most sensitivity and lowest extension and easiest load. I like the idea of a larger version of the Zaph tower but with a single mid, kinda like Troels fusion but larger.

My own suggestion was an open baffle, but with too many options we had to narrow it down based on feed backs and what been discussed, hopefully later projects will include one there are pretty good open baffle projects suggested by members in previous thread if you are interested

I guess Andy covered it pretty well

cool, I have to say i m kinda surprised that XLs have a lot of interests if that's the chosen plan I personally like the two woofers version facing front, but that's something to be discussed later.
