11 | Replace MD, CS, and RES in the list of circuit elements in section 0.50 with:
Cm = capacitance representing moving mass,
Lc = inductance representing driver compliance, and
Res = resistance due to mechanical losses. |
36 | In the formula for f3, the square root sign should be extended to include the "+ 4" term. |
42 | The third 50/50 combination in table 1.21 should be labeled 4 lb/1 lb Fiberglass. |
46 | Item E. of section 1.91 should read "Sensitivity will increase +6dB for a parallel connection and 0dB for a series connection compared to a single driver." |
72 | dt=(d12+d22)1/2 should not be used for multiple port tubes. The correct method is to divide the chamber volume by the number of ports, then plug that fraction of the box volume into the port formula to calculate how long each port should be. |
86 | Figure 3.5 is incorrect; it is actually the same graph as figure 3.4. |
165 | RH should be RL in the C2 equation for Linkwitz-Riley Second-Order Networks. |
183 | 1/(6.2832 f C) should be 1/(6.2832 f L) in the equation for impedance magnitude (says impedance circuit). |
184 | The last line of the paragraph at the top of the right column should read "...for a 4 ohm driver this would be about 0.2 ohms, and so on." |
201 | E5 should be 105 in the Cmb equation. |
201 | The parts list for the BL meter is obsolete. "Helping Hands" Project Holder #64-2093 has been superseded by #64-2991. Self-Adhesive Alarm Foil #49-502 is no longer carried. |
204 | Formula 9 is missing (formula 10 is shown as 9). It should be Qms = fs x sqrt(ro)/(f2 - f1). |
205 | The formula for Qts' has an error. It should be Qts' = (Qes' x Qms)/(Qes' + Qms). |
208 | In figure 8.22, there should be a connection dot connecting the 1000 uF cap, two 650 ohm resistors and driver. DC 09WER SUPPLY should be DC POWER SUPPLY and AC VOLT METER #2 should be a DC VOLT METER. |
251 | In table 12.1, Vas of Audax AP130Z0 should be 10.9 liters. |
