[QUOTE="Art Welter, post: 133669, member: 52"] Re: New DIY Mid High Peter, Nice work on your cabinet! Although the 4594 is certainly a fine driver, it does not have[I] much[/I] more (if any more) output in the 650 – 800 Hz range than a "normal" dome diaphragm compression driver, in fact, the "old reliable" EV DH1A has similar distortion at [I]five [/I]watts in that region compared to a 4594 at only [I]one[/I] watt. For that reason, (and many others..) I decided to use offset horn loaded 10" drivers to cover around 80-800 Hz in my latest design, the SynTripP. Used neodymium drivers to keep weight under 34 pounds (15.5 kilos) for the 26.5" wide x 11.25" tall, 15" deep (67.3 x 6.075 x 38.1 centimeters) main cabinet which also incorporates a tilting stand mount adjustable over a 40 degree range. The secondary horn is 41" wide x 25.5" tall x 7.5" deep (104.1 x 64.8 x 19 centimeters), weighing about 5 pounds (2 kilos).
