Hello, is here someone who has some experience with Turbosound TMS 4 cabs and has an 8 pole connector to them? We have 4 of them, but there are no original drivers nor xovers in them. We are looking for some help to power them. Anybody who can help me?
kindly regards

Firstly I have no first hand experience of these cabs.
But I looked at the spec. sheet and it says that they are a bi-amped box with a recommended crossover frequency of 250Hz. So if you have four boxes, and your 18's are 8 ohms each, then you could run two 18's off each side (4 ohm total) off a two channel amp. If there are no crossovers already in the boxes then you will need to find four passive crossovers of the correct frequency / slope to split the the sound between the 10" mid and the hf, bearing in mind the impedence of each unit. Once you have done this you should be fine running two 10's and two hf (ie two boxes)off each side of a two channel amp. The amp does not need to be as big as the one you use to power the 18's. The wiring to parallel up two bi-amped boxes per side on a set-up powered by two amplifiers will be pretty straight forward. Dont forget to set the limiters on your LMS properly before you test the system for the first time. Hope this helps. |

Hi
this is easy 4+/- to 1" 3+/- to 10" 2+/- TO 18" 1+/- linked to output NL8 TMS-4 run 1" 3K15Hz to Air, LR24 10" 250 to 5KHz LR24 18" 30 to 250Hz LR24 In the day we ran Crest Fa-901 on 1" C-Audio SR 707 on 10s and 18s My current rig uses TSA 4-1200 -4dB on 1" -1dB on 10" SAE PCM-13 -2db on 18" 0dB to 21s Note the 1s and 10s run OUT OF PHASE with the 18" so either wire them backwards in the box or invert on the DSP, NEVER invert phase in an amp-rack as this is shoddy practice. |

Hey, my friend has 2 TMS4 crossovers. If you can use them let me know.
Good luck with the sound :) |

It's all about the bass!

They are not crossovers as they do not split a frequency band, they are hi pass filters that need to be fed with a 250hz - 22khz signal and they let frequencies higher than 3.15k through to the compression driver, whilst the energy from 250hz to 3.15khz is dissapated as heat, it makes overdriving the mid high quite easy until the filter melts.
