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

Thanks!

Hi, Not particularly with a 6.5" bass/mid, design as in post 9,

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?

tpsorin · 14th July 2007, 07:38 PM

the tweeter polarity has to be reversed?

This is the simulated response with reversed tweeter:
(tweeter Cs modified to 32uF, 100uF)
