[QUOTE="Andy King, post: 218622, member: 17087"] Hello all and time to renew this thread. Please forgive some of my questions, I am an ex lampy who retired some years ago, but now feels the need to "dabble" again. I have a small PA thats used for DJ parties and bands (about 150 capacity) and would like to improve over what I have. I have read all of Peter's design threads and this box is the one that I feel offers what I am looking for in terms of performance and portability. As such, I feel I have learnt a lot, but still have much to ask, so here goes..... I like the idea of a simple build and utilising the TMM layout makes sense to me. Does utilising the MTM layout either with a flat front baffle as per Max's drawing [URL='https://soundforums.net/community/threads/double-10-and-horn.13224/page-3#post-204534']here[/URL], or hornloaded as per Jaroslav's drawing [URL='https://soundforums.net/community/threads/double-10-and-horn.13224/page-5#post-211845']here[/URL] make any difference to speaker performance? By that, I am referring to overall output and/or sound quality? If so, would you say its a substantive difference, or just a bit? Did anyone produce a final drawing for the TMM layout? Is there a cut sheet drawing, or CAD files available? Drive unit choice seems to have come down to B&C, as I have had great results with them in the past and I also know several people who have had exscellent results with them. As such DE1090TN on the RCF horn flare and either 10NDL64, or 10NW64. Thoughts and observations appreciated. Also as an outsider, the added lower bass response of the 18 sound 10NW650 appeals, it also appears to have a slightly flatter frequency response which I presume will help and am possibly erring towards this driver. I should point out that speaker building is new to me, although I have built several laser systems (including mid frame argon & krypton), so I'm not totally useless. I also havent any audio measuring, or test equipment, hence wanting to keep this relatively simple. With this in mind, would a passive crossover between the mids and tweeter, be viable, or is there too much signal processing involved? And finally, would fitting a plate amp work? Probably 2 channel with basic DSP. I guess this would be better than a passive XO and provide a degree of processing and equalisation. Any recommendations? [/QUOTE]
