I would like to have a large sweet spot. What factors have influence of this? Baffle? Crossover ?

Thanks!

Hi!
Very easy and good proven speaker is Embla built by Seas.
If you search on internet you can find box dimension and crossover schematic. It is a two way built and tested with good result. Now is discontinued that why you have all plans. I built and sounds good. You do not need recalculate crossover. Better go with already done one than with suppose working one.
Hope this help you.

if still interested:

I would buy 29TFF/W and 27TBFCG or 27TDFC. Then use 27's chamber with 29 Tweeter. You will get best seas standart textile TW. (I tried this with a friend! and comapred to many seas standart drivers and measured...)

you can sell the rest as 27TBF/G or 27TDF.

If you still plan 2way system. I would use two 18cm woofers in MTM.
If you think of 3way you can try seas CA21rex/DD from madison sale with MB quart mid (also in sale) and some TW (22TAFD for example)

already exists a simulated crossover for this:

Unfortunately, the SEAS is hard to get here (I need to wait 1month+)

I came up with a project with Dayton drivers. What do you think about this?
