Woofer for TB75, e.g. W26 or W22?!?

[leifislive]

Hi,

I am looking for either a 10" or two 8" to be mated with the TangBand 75 dome. The woofers should have <1% THD at 40Hz and be useable for a xover point at about 600-650Hz.

Having checked Zaph, Mark K and some other resources, I am still undecided.

The Daytons are good in the low midrange but lack performance in the bass department.
The Seas W26/L26 seems to be good in the bass department, but I can't decide, whether x-ing over at 600Hz would be OK.
Somehow two W22 appear to be tempting, but I can't find good data on their distortion profile.

I haven't looked into the Scanspeaks in more detail yet.

ATC would also be a candidate, but no data.

I appreciate your thoughts.

Regards,
Leif
