Rayman Posted August 5, 2022 Share Posted August 5, 2022 So the Rayman (amp killer) strikes again, I’ve lost count of how many tweeters and amps generally I’ve destroyed over the years. The latest is the 1” tweeter from my TC BG250 1x15 combo. Its a pathetic looking plastic component, which I want to replace, question is, can I just drop a 300W rated car stereo tweeter in there? Or does it have to be like for like? Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted August 5, 2022 Share Posted August 5, 2022 You can't do that. BTW, the usual reason for blown tweeters is that the crossover is dodgy, and does not provide adequate protection from low frequencies. They also tend to use cheap tweeters. You may be able to upgrade it, but no one can say how without knowing what's in there for both the tweeter and crossover. 2 Quote Link to comment Share on other sites More sharing options...

Bill Fitzmaurice Posted August 5, 2022 Share Posted August 5, 2022 This is a proper tweeter for electric bass: https://eminence.com/collections/bass-guitar/products/bgh25_8 Don't be thrown by the 25 watt rating. That's for the actual power in its passband, which is on average only 8% of the full system power. All tweeters used to be so rated, but it became too difficult for people to comprehend that of a 300 watt program perhaps 25 watts goes to the tweeter. In the cabs where I specify this tweeter I use a 4th order high pass filter that doubles its power handling. 2 Quote Link to comment Share on other sites More sharing options...

42Hz Posted October 24, 2022 Share Posted October 24, 2022 (edited) Hey, @Rayman. Have you tried the Eminence tweeter in your BG250-115? Edited October 24, 2022 by 42Hz 1 Quote Link to comment Share on other sites More sharing options...
stevie Posted October 24, 2022 Share Posted October 24, 2022 (edited) You might like to look at the P.Audio tweeters, @42Hz. They're used by a lot of bass cab makers and are half the price of the Eminence here in the UK. Edited October 24, 2022 by stevie 2 Quote Link to comment Share on other sites More sharing options...

I ended up pulling the tweeter out and running without one all together. However, I‘be been suffering with horrendous pain in my shoulders the last few months, which is still under investigation, but it’s stopped me playing at all for now. 1 Quote Link to comment Share on other sites More sharing options...

I will look at p.audio tweeters they seem magnetic so I will need a different crossover. Do they have a webshop? Quote Link to comment Share on other sites More sharing options...

When I dismantled mine it was a 10 ohm resistor in series. Same with a Markbass Combo. Quote Link to comment Share on other sites More sharing options...
stevie Posted October 28, 2022 Share Posted October 28, 2022 Try Blue Aran for P. Audio. They're the distributor in the UK. They do need a proper crossover though. 1 Quote Link to comment Share on other sites More sharing options...
BassBunny Posted October 28, 2022 Share Posted October 28, 2022 There were quite a few BassChatters replacing the "hissy" piezo tweeters in MarkBass CMD 121 combos with the Monacor HT30. Not sure if it's a suitable replacement here but I'm sure someone will be along soon to say yay or nay. Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted October 28, 2022 Share Posted October 28, 2022 Tweeters don't hiss, amps do. That said, the response of the BGH25-8 rolls off above 8kHz, where there's no useful electric bass content, but plenty of hiss. 4 Quote Link to comment Share on other sites More sharing options...
Stealth Posted December 8, 2022 Share Posted December 8, 2022 Confused . com mines fine but get really harsh way before the Amp/driver run out of steam. I do like a bit of tweeteridg. Anyone dropped one in with success ? Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted December 8, 2022 Share Posted December 8, 2022 A harsh tweeter is an indication of high THD, which can be sourced by the amp and/or the tweeter. When it's the tweeter the usual reason is a poor crossover, which allows far too much low frequency content to reach it. The only thing most manufacturers go cheaper with than the tweeter is the crossover. 1 Quote Link to comment Share on other sites More sharing options...
