I dropped out of engineering school after my second year and switched to music :-) I've always wondered about this issue - my guess is that you might be able to rig up some kind of transformer to convert the 4 Ohm speaker to 8 Ohms. I guess you'll have to find a speaker technician, or maybe someone who made it all the way through engineering school. When you find out, PLEASE let me know.
: Thanks for the response, Rob. I suspected what you said about the 4 ohm cab being too dominant in parallel with the 8 ohm 4x10. My original plan was to just use the new 4x10 alone, in hopes of getting enough extra volume from the added surface area. I haven't had an opportunity to try it live yet, so I don't know for sure if it's a lot louder. To tell you the truth, I love the way my Eden cab sounds, and it sure looks sweet on top of the SWR. What about using some kind of ballast resistor to bring the Eden cab up to 8 ohms. Is that done?
: : Hey, Geoff!
: : Using mismatched cabinets is not really a good idea - the D210T will probably suck up most of the power, so the 4 X 10 won't do much. The amp can probably handle the lower impedance under most conditions, but you're gonna be pushing some high volume, so it's kind of risky. Have you tried the 4X10 by itself? Does the increased surface area compensate for the output reduction (you'll get about 200 Watts at 8 Ohms)?
: : Good Luck,
: : Rob
: : : I have an Eden WT-300 amp, with a 4 ohm Eden D210T cab, and I've just acquired an SWR Workingman's 4x10T 8 ohm cab to help me push some more air with the blues/funk/R&B band I'm currently with.
: : : My question is this...
: : : The nominal impedence of the cabs in parallel is 2.7 ohms. Is this gonna fry the Eden Traveler, or do you think she'll be able to handle that kind of current draw? The 4x10 cab moves a lot more air than the 210T by itself, but six tens and a pair of compression horns would really be sweet, if the amp doesn't go up in smoke because of it.
: : : Thoughts and opinions welcome.
: : : Thanks in advance.
