SVT 610 - Crossover bypass - ohm change?

[the dude]

If I bypass the crossover, am I o.k. on ohms? I'm not using a 2nd cab - and a 70's SVT tube head, so the ohms can move a bit, right?

I always have the tweeter turned down, and I'm thinking I'd have better sound with it out of the loop (where the speakers get full range.)

Thx.

If you bypass the crossover and run the woofers full range you will not have effected the cab's impedance (ohms). Play and be happy!

If that's like most bass cabs, the tweeter is highpassed but there are no crossover parts affecting the woofers, they're already full range. You can remove the whole works and be just fine but plug the hole the tweeter was in so it doesn't affect the tuning of the cab or... Easiest thing is to leave the tweeter in there and just unhook it.

If the 610 uses a "real" crossover, rather than just a series capacitor in the tweeter's (+) feed, then simply disconnecting the tweeter really isn't an option. (I'll spare you the electrical theory and simply urge you to verify the type of crossover you have, before you make any changes.)

In the "real-crossover" case, the safest bet is to remove the crossover entirely from the cab (I mean in an electrical sense) by wiring the input jacks directly to the speakers and making sure nothing else is connected to the input jacks or the speakers. If you find this is what you have to do, but accessing the input jacks is impossible, then you can install a second jack plate. Know where your internal bracing is located before you cut! You can get plates pre-drilled for Speakons and/or phone jacks. You might even be able to find a plate the same size as the jack plate+crossover you have now (if that's how they're doing it), and do a simple swap.

You can disconnect the crossover and instead connect the woofers directly to the cab input, but don't bypass the crossover circuitry (i.e., connecting the tweeter in parallel with the woofers).

So I pull the back panel (crossover is mounted on it) and take it to my amp tech who looks up the schematic and tells me it's not a full crossover - the speakers always get full range. There is protection on the board for the tweeter, but no reduction of high end for the speakers.
So I'm good to go?

You can safely disconnect the crossover and tweeter.
