Since the T/S parameters are available for these, why not design your own, using one of the free box simulators? I can recommend WinISD. The learning curve is not too steep. That would give you the choice of compromise between expected performance and bulk. Original Monitor Golds were designed for maximum LF extension, at the detriment of power handling and intermoulation/Doppler distortion; this may not be your target.ruffrecords said:I have a pair of 10 inch Tannoy monitor golds that I would like to build into bass reflex cabinets.
