B.Flat Posted October 10, 2020 Share Posted October 10, 2020 Hi. So, I have a 2 X 10" cab (which is really two 1 X 10's", as the internal space is divided) to which I would like to add a high frequency driver. The advice I am looking for is, which driver (the 10" are Deltalite 2510's) which needs to be as small as possible as space on the baffle is tight, and which x-over (off the peg if possible but would build one if not too difficult). Is the tuning of the cab important regarding this x-over ? The cab is driven by one side of a Yamaha PX 3 power amp, 500w at 4ohms Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted October 10, 2020 Share Posted October 10, 2020 I recommend the Eminence BGH25-8, as it's made for electric bass, not PA. I can't recommend any off the shelf crossover. I specify a 4th order 2kHz high pass with this driver, but it's very much DIY. Assuming your woofers are parallel wired this would be the low pass filter for them: Quote Link to comment Share on other sites More sharing options...
B.Flat Posted October 10, 2020 Author Share Posted October 10, 2020 Thanks Bill, exactly the clear advice I was looking for, I am indebted. Brian Quote Link to comment Share on other sites More sharing options...
B.Flat Posted October 10, 2020 Author Share Posted October 10, 2020 Hi again Bill, I forgot to ask if a variable attenuator can be added to the circuit ? If yes, could you please advise me. Brian Quote Link to comment Share on other sites More sharing options...
Bill Fitzmaurice Posted October 10, 2020 Share Posted October 10, 2020 Use an LPad, installed between the high pass filter and the tweeter. Quote Link to comment Share on other sites More sharing options...
B.Flat Posted October 10, 2020 Author Share Posted October 10, 2020 Hi again Bill. From the heart of France, thank you again. You have been most helpful. I will suggest to President Macron you should be reccommended for the Légion D'Honour ! Brian Quote Link to comment Share on other sites More sharing options...

B.Flat Posted October 11, 2020 Author Share Posted October 11, 2020 I'll see what I can do, but don't hold your breath ! Quote Link to comment Share on other sites More sharing options...
stevie Posted October 15, 2020 Share Posted October 15, 2020 I'd be very careful with this if I were you, @B.Flat. There's a very good chance that the lowpass circuit Bill has suggested will drop the impedance of your speaker to 2.5 ohms. Your Yamaha is 2-ohm stable - so you should be all right. However, you should be aware that the circuit will probably also induce a nasty peak at 2kHz, which won't be very nice. Just sayin'. Quote Link to comment Share on other sites More sharing options...
