| testing a crossover I don’t know it’s can be of any help, you can find the xover schematic here: https://ucarecdn.audiogon.com/a89e98dd-d4a0-4acf-9f74-934683ea9b70/-/autorotate/yes/ | |

| Chained speakers signal connected in series @fiesta75, I think it was 7 or 8 years ago, my friend use Hornresp (http://www.hornresp.net/) did a simulation on his speakers and found that connect two speakers in series the low pass filter cutoff frequency get lowered, our conclusion was the... | |
| Chained speakers signal connected in series @fiesta75, Can we agree that Rt equals 16ohms in series? YesCan we agree that Lt = L1 + L2 in series? No, IMO, the first woofer will see the voice coil of second woofer as an inductor in series, same for the second woofer, it will see the voice ... | |
| Chained speakers signal connected in series I disagree with imhififan’s opinion that the crossover points will change. I believe the Tannoy SGM 10B has parallel crossover, if connect two speakers in series, the LF section will be #1 speaker low pass inductor --> #1 speaker woofer --&g... | |
| Chained speakers signal connected in series You can connect two speakers in series and it won’t harm the amplifier. BUT because of two sets of crossover connected in series the sound it produce will be totally different from just one speaker connect to the amplifier! Both woofer in each spe... | |
| Dahlquist DQ-20i crossover schematic https://audiokarma.org/forums/index.php?attachments/dq-20i-schematic-jpg.117926/ you need to register as a member to view the file. | |
| testing a crossover You can find all the photos herehttps://systems.audiogon.com/ Without drivers connected, The HF measurement should equal to the DC resistance of the 0.22mH inductor. The MF measurement should equal to the DC resistance of the 2.5mH inductor + 2.2Ω. | |
| testing a crossover @fiesta75 and pragmasi, IMO, the layout of components is not ideal, especially those capacitors that seat on top of resistors! since he is at it, I think it's time to fix that... | |
| testing a crossover Hi Guys,thankyou so much for all your help,but i still dont see a solution to this problem,in my opinion there is shorts in both xos,please see below- LEFT SPEAKER / RIGHT SPEAKER speaker terminals with everything connected on both speakers MID/H... | |

| testing a crossover ill try draw a schem.but its difficult, but ill do my best @ likklegerry, If you can print-out the crossover pcb photo and add all the component position on it with wiring and post the picture, maybe we can figure out the schematic and go from t... | |
| testing a crossover i would also upload some photos, but as this is my first ever use on this site,im not sure how to do this Go to Virtual Systems page, use the "Create System" to upload photos. https://systems.audiogon.com/ | |
| testing a crossover The formula for parallel resistance is 1/Rt= 1/R1+1/R2+1/R3.... https://www.electronics-notes.com/articles/basic_concepts/resistance/resistors-in-series-parallel.ph...Since he measured almost 8 ohms then the total resistance will be 1/8 ohm + ... | |
| Replacement capacitors exploding @rodman99999 Thank you for the link. @fiesta75 No apology necessary, your earlier post lead me to these two document from cornell-dubilier and caused the confusion: http://wiki.ece.rose-hulman.edu/herniter/images/0/03/Aluminum-Electrolytic_Capacit... |
