[QUOTE="David Morison, post: 148591, member: 2076"] Re: MTM top cabinets for vertical and horizontal. ...has it been done Wavelength = Speed of Sound divided by Frequency, so for 1000Hz you have 344/1000 or 0.344m (approx, the exact speed of sound varies with temperature, humidity and I think atmospheric pressure too). Quarter-wave therefore = 0.086m, so there's no way you're getting the centre of a 15" driver within quarter wave of anything else at that frequency. The ME60 is 0.237m tall so the closest you're getting the centres of the MF & HF drivers (even if the chassis of the 15" touches the horn) is 0.312m, which is a quarter wavelength of approx 275Hz.
