Another LSI15 crossover discussion
Hello all,
Have a pair of lsi15 want to upgrade the crossovers. I have the schematics. But don't know what brand of caps, resistors, wire gauge ect.. to get also see a lot of discussion but no real builds available. Someone said don't use stock 5v use 10v. Would the 5v be better for protection so it goes(pops, shorts, burns) instead of the speaker?
Only consensus is mills resistors. But also seeing different ohm ratings posted. Schematics say 2 ohm. Link from forum users are for 3ohms. Caps haven't see much about them. I'm thinking about just keeping everything the same specs just better parts. But if crossover can be improved would like to do that. I'm sure is this has been answered before. Can't find it. Would buy new if I could find any, and if price is affordable. But can't even find any for sale. So asking here for suggestions.
Also the 8"woofer. Is there any suggestions of new Polk Audio (don't want another brand) woofer that is available and plug and play? Keeping with the 4 ohm. I'm not hating the bass. But not wowed by it either. If I can improve for decent price would do so. Suggestions are db840. But can't find any. I found db840dvc. Don't know if they are the same. Or if the specs are the same. And if they will fit.
Using a Marantz 5008 receiver, yamaha p2700 amp.
Bi-Wired with actual 12 awg solid strand copper wire.
Powered with Tripp Lite LCR2400 line conditioner. Just recently read not supposed to use line conditioner on the yamaha Amp. Any truth to that? Opinions?
Thanks

Post your question in one place only.
Resistors are measured in watts not volts. You want a 10 watt resistor to replace the stock 5 watt.
For the capacitors you should use the same uF value while the voltage value should be equal or greater than stock. Film caps will have higher voltage values. Sonicap and Clarity are forum favorites. Avoid Solen, Dayton and Bennic if at all possible, especially in the high frequency circuit.
Always plug your amp straight into the wall socket.
The db840DVC is the same thing.Political Correctness'.........defined

Negative, Jesse.
The DVC is the dual voice coil version. You want the SVC or single voice coil version for the LSi15s.

Is the RD-2505 the stock woofer?

It is getting harder to find the Polk car subs anymore. I think they may have dropped the car audio line. Here are the small parameters that you may use to find something similar to the DB840 svc.

Can only find Solen 130uf caps. Can't find it in Sonicap or Clarity. What do you recommend

You have to use electrolytic caps due to space, or get extremely creative with mounting or go external.
But have to be careful not to crowd the enclosure since it's a tight space- Not Tom ::::::: Any system can play Diana Krall. Only the best can play Limp Bizkit.
