MK3 XL

Easy enough to draw comparisons about cone area: just look at Sd. 😉 TB is rated at 220cm^2. The 12P (for example) 147.41cm^2.

It's because of variations like this that I tend to use approximates regions of driver emitting surface rather than basket diameter. The latter worked fine when there was somewhat less variation in basket materials (and to a point surround design) but less so now, so rated Sd gives IMO a better rapid comparative basis between units purely in effective / acoustic size terms.

I Will be using tang bang w8-2145
 
Hi Dave, i sent the recipe on decembre 17 but here it is again.

Thanks

The TB will work with Joan. Might need a bit of juggling with the damping as in an ideal world it would be better with an acoustically larger volume, but assuming the published data is reasonably reasonable (just assuming, without prejudice either way), it should give, er, reasonably reasonable results. Just watch for any compression overload at higher levels. Unlikely, but strange things happen from time to time. Fortunately not often. 😉
