alexclaber Posted July 27, 2009 Share Posted July 27, 2009 Right, I do believe I've finally made some decisions regarding a badass wee multi-purpose PA speaker. It will be a compact 3-way design, using a high-excursion 12" woofer, a very high-sensitivity 6.5" midrange and a rather nice horn tweeter. Approximate size should be 24" high x 13.5" wide x 13.5" deep. Approximate weight should be under 35lbs. So that's 600mm x 340mm x 340mm. Best used with an amp that puts out 500-1000W per channel into 8 ohms. To get absolute maximum output the cabs should be used with a Crown XTi, for which I will be writing a model specific DSP profile with EQ/compression/filtering, but even with a generic power amp with no EQ they will exhibit smooth extended response and very high max SPL with low distortion. I can certainly provide patches for other outboard or intergrated DSPs. The aim is for a pair of these cabs to have enough output and bottom for smaller gigs without any subs being required, to be used as wide-dispersion stage monitors, and to be used in conjunction with subwoofers and extension cabs for larger gigs. They won't be cheap but they will be very very good. Alex Link to comment Share on other sites More sharing options...
alexclaber Posted July 29, 2009 Author Share Posted July 29, 2009 I've also worked out an alternate version which should always be used with subs (and is thus a few dB louder). Alex Link to comment Share on other sites More sharing options...
acidbass Posted July 29, 2009 Share Posted July 29, 2009 As previously expressed, I am very interested in the development of these, roll on the build diary! Link to comment Share on other sites More sharing options...
bumnote Posted July 29, 2009 Share Posted July 29, 2009 If they come out at 35 lbs they are marginally lighter than the ev 300 sx plastics so that should be a plus point Link to comment Share on other sites More sharing options...
warwickhunt Posted July 30, 2009 Share Posted July 30, 2009 I'd like to talk about the proposed PA system Alex, 1 sub and a pair of mid/tops. How far are you off having a finished product and what is the price? We (the band) are in the process of looking at a new system and will likely as not be reaching some form of decision on passive v active in the near future. Cheers.

alexclaber Posted July 30, 2009 Author Share Posted July 30, 2009 Quite a long way off at the moment. Although I'm pretty set on what I'm going to do regarding the components, tuning, dimensions, I have get to get into the details of the crossover design. Costs-wise, I'd expect it to be in the region of £1500 for a pair of fullrange 3-way speakers, though I might do some discounted introductory prices to get the ball rolling in that market. When it comes to subwoofers I'm still working through the ideas. Probably going to go with a dual 12" direct radiator model that is suitable for bands and DJs, and then a single 12" horn which is better for install or large PAs (because you need lots of them or a guaranteed corner/wall position to get the benefits from the horn). Regarding passive vs active, the lower echelons of the market seem to all be plastic and active whilst the better gear is plywood and passive with outboard DSP etc. The latter approach is certainly more versatile. One thing I hope to achieve with these is actually have a small pair of cabs that can really whomp without a separate subwoofer! How satisfying would it be as a function band to take such a small simple PA with you and get better sound than you did with those plastic tops and a subwoofer that weighed a ton?
