Phaseone

No doubt that I push them at times, and I am sure peak passes go well over the 100 rating. Did pull the voice coil tonight and took a closer look at the dust cap. No damage to the aluminum core the coil is wrapped on, the light oxidation on the edge is still intact, and the dust cover resides about half an inch above the coil, so no contact there.. My thought was the old paper cones are just getting a bit soft from the hard use. Was hoping to recone with a bit tougher material like the 42, but couldn't find out coil diameter on the 42 and core thickness to fit into the magnet channel. I can reuse the voice coil, but if the cutout on the 42 is for a larger coil, that won't reach. I will likely go with the 22 cone kit and see how they hold up. Running no bass boost, eq is flat from the media player 11 program. Main listening is country and the occasional movie. Thank you for the input.

I have several sets of Heresy's and drive them kind of hard, love the live sound and feel they put out. I've had 4 cone fractures at the glue line of the dustcover in the last year. Would the K42 rebuild kit fit into the K 22 frame? Comments? Thanks for the information. Jim

The amp. An amp with at least twice your speakers rating, if not more. The headroom translates to extra punch for the low freqs which tend to drag down most amps, hence the need for subwoofers. Bass can steal most if not all of the reserve power in amps, and with no reserve, the whole freq range suffers. I am speaking from a vintage standpoint, with some of these new class D amps, I am not sure how they are geared to supply short term high demand passes in the music.

I have an HBR where the dust cap somehow worked itself loose, alcohol may have been involved. It has feathered apart at the glue seam about 120 degrees around. The coil is still intact, but it gives a nasty vibration now at certain frequencys. What would be an acceptable glue to anchor this back down? I had a spare woofer that is now installed, so I have time to make the repairs the correct way, if it can be done without crimping down sound quality. Any and all assistance appreciated.
