    I did notice (and was a bit chagrined by) Erin's lack of knowledge, or preparation for the interview, but I have followed all things JBL for longer than he's been alive, well, maybe not that long....

    I found many interesting points in the second one, including, but not limited to - the synergy of tubes and CDs, invest in a great woofer, his preference for wider dispersion. There was more...and...

    Thank you - informative...particularly regarding power compression. I think I experience that with my LE14H-1-based system when played loud, or the room is all wrong. Don't know.

    If the 2216Nds can play to the low 30s (32 to 34) in the correct box what would the size of the box be? I don't want to augment with EQ if possible. I don't trust my skills at plugging the T/S into...

    What are the objective improvements over a, for instance, LE14H-1 or your doorstop example 2235H? Inquiring, edification starved minds, want to know.

    Well, I guess it's easier to do the crossover electronically and just as easy to put a couple resistors and a cap together to make a compensation circuit. Maybe (just spitballing here) I can put...

    Digital will work if it has tuneable CD compensation.
  10. Looking for two way crossover with built-in CD compensation

    I am trying to step into a new realm where I can skip building passive crossovers and do it electronically.My main concern is to be able to apply CD compensation without adding passive...

    Might have been a previous re-cone and the cork wasn't completely scraped off.
  12. I weighed all the parts on a nice little kitchen...

    I weighed all the parts on a nice little kitchen scale I have. I also have DATS but didn't even consider it because the moving mass is the weight of all the moving parts. What better way to find out...

    I just bought a pair of cone kits for 2234s and had the mass rings in my possession. The weight of the cones with all parts (surround, dust cap, etc.) weighed 102 grams. With the 35 gram mass ring...
  14. Did you weigh just the cone or all moving mass?

    Did you weigh just the cone or all moving mass?

    Common sense pointed me that way, but all y'all are more qualified to weigh in. Thank you.
  16. Adding the mass ring

    Do I use an epoxy or a lesser adhesive?

    You are correct again. Once I flipped the spider, the material naturally fell into place. Many, many thanks. The plan is to glue them up as 2234s sans dust cap, put them in a 4507 cabinet (5 cu. ft.)...
  19. Earl, you were right.

    I flipped the spider over and I now have the look illustrated in those two pictures. The relief of the former above the spider looks right also. If you all agree, I can begin to glue it up. That...

    The spider is in correctly. What your pictures suggest to me is that I need to put the spider on from the bottom of the voice coil so that the excess spider material folds down toward the coil. I...

    Here, I hope, is a picture with the voice coil in the gap centered with a shim. I dry fit the spider on top of its perch. What's left is about 1/8-3/16 above the spider. This gives plenty of purchase...

    Kapton former is 1.25 inches tall. Weight of all parts minus mass ring is 102 grams. Add the 35 grams mass ring for 137 grams total.

    You're all so helpful. It's not rocket surgery, I guess, so I'll dry fit everything and take a picture of it later today.

    I would bottom the coil, make a mark on the coil at the top, then divide the distance by two which would, theoretically give me the halfway point.
  25. I need to be dead sure about this. If I bottom...

    I need to be dead sure about this. If I bottom out the new voice coil and make a pencil mark, then divide that distance in half - will that put me in the ballpark? I can't afford/don't want to have...
