P Audio x12 spec drivers discontinued. As a novice I wouldn't know what to replace them with. The cabinets have been built to spec and I don't want to bugger about retuning them, so your recommendations for a UK build alternative please. (I realise that there are many threads about this already but from various builders in various countries. This thread is Uk specific.) ta muchly. ------------- Tendril A mistake is a mistake only if one learns nothing from it. |

There are lots of options of drivers available in the UK. From PD there is the PD123ER if you want heavy (available from Bluearan) or 12MH25 if you want lightweight. From B&C you could use the 12PLB76 or 12NDL76 or 12HPL76 There are Beyma options but I'm not as familiar with their drivers. |

I have said many times the original and only X12's were equiped with budget drivers. To get comparable performance there is no need to look beyond the Celestion TN1225's. The important part is then the Comp. You can either build them as a M-T-M arrangement which allows you to use any number of 1" comps crossed as low as 1.8K or in more typical M-M-T arrangement and either use a 1-1/4" comp crossed at around 1.2K or one of the BMS 1" drivers crossed as low as 1K although this is probably not cost effective giving the budget nature of the Bass-Mid driver.

unfortunately these cabs are already built tony so MTM isn't an option but i'm curious as to why that arrangement would allow a higher crossover freq. sorry if it's a bit of a basic question  ------------- the only thing more dangerous than a person who doesn't give a f**k is a person who gives a sh*t. |

It keeps the relative path lengths for the 3 drivers as close as possible assuming listening on the comp axis. With a double bass mid arrangement there is always some anomaly because of the physical distance from the comp to the lower bass unit. Lowering the x-over frequency also helps which is why you see a lot of 2" units used in this arrangement crossed at 800-1000hz. But these often sound sub-optimal. No arrangement is perfect its all about managing the compromises. Tony |

this seems to be true for nearly all aspects of speaker design, thanks for the answer  ------------- the only thing more dangerous than a person who doesn't give a f**k is a person who gives a sh*t. |
