I have been playing around with WinISD and found that the 2226H has a nice response curve in a 4.95 cu ft box tuned to 30-35hz, quite similar to the one of a 2234H in the same enclosure tuned to 26hz.
The 4435 uses two 2234H is such boxes, with mutual coupling under 100hz, and seems to achieve a very good LF response.
Could this be a solution to obtain real LF from 2226H ?
Considering that 2226s are much easier and cheaper to find than 2234H (2225/2234/2235 backet and 2235/2234 recone kit), this could be interesting. Group delays are higher, but the 2226H are not that bad in this situation.
The 2226H is also 1db more sensitive and has a much greater Pe.
Could a 2226H be a good substitute to the 2234H for a 4435 DIY ?
WinISD does not show driver excursion, so maybe I am missing something here?
