| JBL 125a refoaming. Before (at left) &
during (at right) |
| |
 |
| This photo shows the JBL 125a finished (left)
along with a finished Infinity IRS 1001 woofer |
| |
 |
| This photo shows the Infinity IRS 1001 5”
woofer in mid-repair with new surrounds waiting to be installed. |

| Project Gallery 2: Reconing |
 |
| A severely damaged Polk Audio speaker voice
coil can be seen on the left side in the above photo. On the right
side is the complete recone replacement |
| |
 |
| The above photo shows the nearly finished
Polk re-coning job. The new cone, spider and voice coil assembly are
seen leaning against the frame. |
| |
 |
This photo shows the magnet label on a pro-audio Eminence speaker. This driver
Is similar to the Kappa Pro Series. It has a cast aluminum basket and is rated at 500 Watts.
Reconing of pro-audio is another service offered by Carl’s Custom. |
| |
 |
The above photo shows the same driver in the above photo that has
been reconed. |
| |
| Project Gallery 3: Crossover Upgrades |
 |
This photo shows an upgrade to an AR-2ax speaker. Solen metallized propylene capacitors have replaced the factory installed ones. Also, the 15 ohm rheostats were beyond repair and were replaced by more robust industrial grade units. |
| |
 |
Here is another AR2ax crossover upgrade. This photo shows the original,
disconnected unit which was eventually removed. |
| |
 |
This photo shows an AR 3a crossover as originally made.
The tan rectangle is the 6 uF tweeter capacitor. The large
Block to the right is the 50/150 uF woofer capacitor. |
| |
 |
This photo shows the new capacitors installed and wired
in the same cabinet as above. |
| |
 |
This photo shows a completely rebuilt large Advent crossover. All parts are new
and temporarily attached to a cardboard sheet for the customer to install back
into their speaker cabinets. |
| |
 |
This photo shows a partially upgraded large Advent crossover. New Solen caps
and a non-inductive resistor were installed in place of the older components. |
| |
| Project Gallery 4: High-end Crossover Upgrade |
 |
This photo shows the insides of a high end 2-way, Swiss made speaker called
the Ensemble Reference. This speaker warranted very high quality capacitors.
The yellow ones are Auracaps and the large black one is a Mundorf 1200V, 6.8 uF
Capacitor. |
| |
 |
This photo shows a comparison of the original capacitors that came with the
Ensemble Reference speaker (ones marked with their measured values). Along
side them are replacement caps of equal value but of much higher quality. |
| |
| Project Gallery 5: More Crossover Upgrades |
 |
| The above picture shows an upgraded 3rd order crossover integrated with the original terminal cup plate used in a two-way Polk loudspeaker. New, 250V 12 microfarad metalized polypropylene capacitors are mounted on a small circuit board and bypassed by two, 400V 0.1 microfarad film/foil capacitors. Also shown is a new, 0.52 mH air-core inductor and new, 1 ohm, 12Watt non- inductive resistor peeking out from under the capacitors. |
| |
 |
| This photo shows a relatively more complex Snell Model A original 3-way crossover. Note the (A) bundled old style electrolytic capacitors and (B)sand-cast resistors. |
| |
 |
| This photo shows the same crossover that has been upgraded with (A) metalized polypropylene capacitors and (B) non-inductive resistors of equal measured values. Note, the unchanged, bundled electrolytic caps and sand cast resistors are components that were not in the critical signal path and were not upgraded. The new, capacitors are rated for much higher voltages which necessitates their relatively larger body size vs the electrolytic caps. |
