Old speakers, new tweeters are a bit too sharp

[Jasonovich]

Your description sounds logical to me - tweeter could short circuit crossover, which could then short circuit the amp’s circuit. Sounds like Hifi components don’t necessarily have safety mechanisms such as fuses on their circuits?

Indeed, some amps have better protection than others.
Nothing wrong with experimenting but better not use with your expensive amplifier 🙂

Haha, no. But it must be hard to short a speaker or crossover? You’d have to blow the resistance while also maintaining the electrical connection, right?

Yes 100% safe without the electrical connection 🙂
All of what you say is correct.
Difficult yes but the risk is there, resistors can burn out.
Airing some caution is prudent but if you think I'm misinformed, I don't mind if I'm proved wrong.
What matters is what you get out of it.
Nice one 😄

Whizzer cones are quite common on cheap full range speakers. There is no crossover involved, the paper cone is just connected directly to the voice coil and helps to extend the high frequency range - you could call it an integrated 'poor mans tweeter'.
For example; this Visaton 6.5" driver that sells for 24 dollars at Parts Express. It claims to have a freq. response of 80-20,000 Hz.
I agree that the tweeter you purchased does not look much like a tweeter.
A lot of cheap acoustic guitar/PA combo amplifiers use whizzer coned speakers as they are cheap. Typically they don't sound too good.

Gosh, it looks like I've seriously reduced these speakers capabilities over the years!! The original config was probably much better. I bought those Altai drivers in 2000 something, assuming the shop I bought them in knew more about these things than me ... then I bought the whatever (higher range) drivers in 2020 (?) again assuming the purveyor would sell me the right thing, foolish. I think I'll consign them back to the loft, although it's been great to remember all the parties etc they've been involved in 🙂

My 4 & 6 year olds going ballistic first time they heard Heartbreaker being the highlight for me!! 🙂
