Jssbzi Posted October 11, 2020 Share Posted October 11, 2020 I have a K-33 square magnet with sp1-1 67-8151 stamped on the back. This peavey looks identical to it. Is it? The guy selling it can't check it for ohms. Is it a 4 ohm driver? Thanks Quote Link to comment Share on other sites More sharing options...
JohnA Posted October 12, 2020 Share Posted October 12, 2020 It IS an Eminence woofer that uses the same frame that a K-33-E uses, made in 1979. That does not mean it has anything else in common with a K-33-E. In fact, it may have been used as a direct radiator as is typical of Peavey. Look for an ink stamped part number on the cone and call Eminence to see what it really is. Ask them, but I'd guess it could be reconed with a K-33-E kit and become one.

Marvel Posted October 12, 2020 Share Posted October 12, 2020 The SP-1 is the cabinet it was in, basically ah FH-1 with attached horn on top. 1 Quote Link to comment Share on other sites More sharing options...
JohnA Posted October 15, 2020 Share Posted October 15, 2020 My FH-1s came with Peavey BW 1504-4 woofers. All I could find said they all did. It was tough and could be reconed in the field in about 5 minutes. BUT, .... harmonic distortion at 100 Hz and be!ow exceeded the fundamental. A K-33-* should work beautifully in an FH-1, maybe it is a K-33 c!one? Quote Link to comment Share on other sites More sharing options...
