MrRubbish Posted November 12 Share Posted November 12 I seem to have blown both my drivers on my Genz Benz NX2 cab. Which I love and always gets comments about how great it sounds… I removed them and tried the 9v battery test and nothing. I was using my 900w shuttle head on the last gig and it got a bit of hand with the levels… what replacement drivers would you recommended I replace with? So I don’t have the same problem in the future? Faital Pro 12PR320? thanks 1 Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted November 12 Share Posted November 12 Those look like OEM versions of the 12PR300, so it's highly unlikely they were at fault. The PR320 isn't much better, if at all. You'd have to go FH520 for that. I'd have the old ones re-coned. 2 1 Quote Link to comment Share on other sites More sharing options...
ebenezer Posted November 13 Share Posted November 13 I'm amazed they both blew!...I had the same cab and ran at quite high volume levels and never had a problem. 1 Quote Link to comment Share on other sites More sharing options...
MrRubbish Posted November 13 Author Share Posted November 13 Yeah I’m not proud of it.. the amp was running on full for most of the gig and then I kicked a fuzz and octave pedal in and the first 12 went.. then about 10mins later the 2nd went. A fool I am.. alas it sounded awesome until they went. Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted November 13 Share Posted November 13 An octave pedal is what you use if you really really want to blow drivers. 🤥 3 1 Quote Link to comment Share on other sites More sharing options...

I should imagine not enough cabs or wattage (OP mentions he was running the amp flat out) to shift sufficient air didn't help, either.

MrRubbish Posted November 14 Author Share Posted November 14 So I will order some Faital Pro 12PR300’s or should I go for the 12PR320’s? what’s better? Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted November 14 Share Posted November 14 The 320 has lower Fs and longer Xmax, better for the low end output. 1 1 Quote Link to comment Share on other sites More sharing options...

Funny you should say that as I was considering putting a PR320 up for sale. PM me. AS BFM says it has close to twice the XMax and goes lower so you would not need to push so much low end power from the amp. Quote Link to comment Share on other sites More sharing options...
agedhorse Posted November 14 Share Posted November 14 It's very uncommon to see a failed driver in those cabinets. The best replacement is the 12PR300, it's not exactly the same but the primary difference is in the mid voicing (the 12PR300 is a little more polite) and the original parts have a slightly longer VC winding height. The important part is that the 12PR300 will work with the same cabinet tuning as the GNX-12350 without any fuss. I do not recommend anything else. 3 1 Quote Link to comment Share on other sites More sharing options...

I’ll order some of those. The ones that died had done at least a 1000 gigs over the last 10yrs or so.. lasted well I thought Edited November 15 by MrRubbish Quote Link to comment Share on other sites More sharing options...

In the same box tuned to the same frequency the 12 PR 320 has the advantage in low frequency sensitivity (first chart) and maximum SPL (second chart). 1 Quote Link to comment Share on other sites More sharing options...

That's not the box and tuning of the NX2, and the mid voicing is much better (IMO) on the 12PR300 (as well as our custom variant). That's a way overdamped application which I have always stayed away from. Edited 12 hours ago by agedhorse Quote Link to comment Share on other sites More sharing options...

When you see that dip, as with the 12PR300 on the graph, run like hell. Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted 4 hours ago Share Posted 4 hours ago The dip on the maximum SPL chart is where xmax is reached. Since the 320 has considerably longer xmax it also has higher maximum SPL at those frequencies where xmax , rather than thermal power, is the limiting factor. You really don't want that dip in the 60-90 Hz range, as that's where the output demands of electric bass are the highest. Quote Link to comment Share on other sites More sharing options...
