Ok I dove off and decided to build my own MTM center channel speaker. I could not find a design that I thought would match my main speakers, ESS monitors which have a ribbon tweeter. So the first thing I did was to buy a few books on speaker building and the Bass Box and Xover Box software. After looking at several speaker/tweeter combos I sellected the Audax HM170C0 and the HI-VI RT2C-A. The box is 8.5" X 10" X 24". This is a ported inclosure. I have yet to finalize the port. But it looks like about 3" X 2" X 5" for a target tuning of 61 Hz,I chose this becaust this driver has a 6 db sag below 500 Hz to Fs. It does seam to have a nasty 4 db peak at 600 Hz and a cliff at 5k. So the crossover is a 2nd order L-R at 2400 Hz for the woofer and a 2nd order L-R at 2700 Hz for the tweeter. Acording to the model this should be fairly flat. I use the measured speaker from Audax in a 15 L ported enclosue and Hi-Vi's web spec and compared to some other measurements I found at various places. I built the crossover with theta capacitors for the RT2C, as Wayne recomended in his Veritas design. I also opted for flat wire 16 guage inductors. After I built the crosover I made a cardboard box and installed the speakers/crossover and listened to them, they had incredable midrange detail and crystal clear highs, the botom end was lacking but hey this was a cardboard box. I am about to finish the box
Am I just ignorant or am I missing something? I am planning on buying a clio lite system latter this year maybe then I will see something, but so far I am a happy camper and it was not that scarry to build the crossovers. Is ignorance bliss? What is baffle step?
