In theory: No. |

Isn't there an EV MT cabinet with 4 15s? Geri O |

Why not (sincerely)? |

How big of an amp one needs depends on the final power handling of the cabinet (not necessarily the summed power handling ability of the 3 drivers). |

Honestly, there's lots more questions that need to be answered to fully consider the design. |

Hi Geri I am not familiar with a 4X15 MT cabinet but I have some of the MT4L cabs that are 4X18". Not a very easy cab to move around and with the new OH&S legislation there are not enough handles on the cab to allow it to be lifted without breaching the maximum weight per person limit! These cabs are wired as two pairs of drivers per box. Regards Baron |

Oops, my mistake. You are indeed correct, I mistook your answer as a negative response. |

My apologies, Geri O |

My thought was for the future when (only in my dreams, probably) I have my own speaker company, BHFSpeakers, and the professional division BHFProfessional would make a 3x15" vented cabinet loaded with 3x Ciare 15.00SW. With recent changes, the SW range can now handle 1250 watts AES, up from 1000 watts AES so you could definitely pump in the power (3,750w into 3.2 ohms). The tuning point would be kind of low and the major caveat that comes to mind is that you wouldn't want to try and use them outdoors. I wanted to test the waters and see whether or not people would trust a cabinet that employed three 15" woofers instead of two 18" woofers. I was inspired by a triple-15" cabinet made by Stage Accompany. |

Hi Rory, Unfortunately we have to work within the limits imposed by physics. Hoffman's iron law is always at work. Even when we can get ahead of it's predictions with highly optomized bandpass designs, we are still subject to the same trade offs in box volume and sensitivity as related to low frequency extension. A rule of thumb Tom Danley loves to remind me of is that for a given box volume with an optimized design, you take a hit of 9dB! for every octave you want to push the cut-off lower. Regards, |
