I've measured an initial grouping of nine 6.5"/7" woofers: -ScanSpeak 18W/8545K00 -Usher 8945A -SEAS CA18RNX (H1215-08 ) -Vifa NE180W-08 -Dali Ikon 6 MK1 -Fountek FW168 -Dai-ichi W6S-52 -MCM 55-5665 -Response CW2194
Some extra tests unique to this grouping have been added to evaluate bass capability and Le(x) which is a key contributor to intermodulation distortion.

New measurements added: -DLS Ultimate U2.5 (Morel CDM54) 2" Dome -SB Acoustics SB65WBAC25-4 2.5" -Dynavox LY302F 3.5" -MCM Audio Select 55-5650 3.5" -Peerless TA6FC00-04 2"
Really impressed with the Dynavox LY302F - probably the best 'full range' driver I've tested to date. The MCM 55-5650 would also make a fine midrange - and I suspect it is a close relative of the Dayton RS100 ;)
