barefootpoet Posted August 25, 2011 Share Posted August 25, 2011 I finally decided to take the plunge and build an Electro-Voice Patrician IV. I've always found this particular speaker both bold and interesting and a wonderful example of 1950s vintage American Hi-Fi. So far I've built the front portion of the bass horn assembly and should complete the inside chambers this weekend or next. Wish me luck.

BigStewMan Posted August 25, 2011 Share Posted August 25, 2011 wish i knew how to do stuff like that. Good luck, hope it turns out great. Quote Link to comment Share on other sites More sharing options...
barefootpoet Posted August 26, 2011 Author Share Posted August 26, 2011 Thanks. And yes, I have the full set of plans that was provided by E-V in 1955. Its a complicated project but very educational and makes me truly appreciate the early pioneers of Hi-Fi like Mr. Klipsch and Electro-Voice. Here's a side view of the edges attached.

barefootpoet Posted September 18, 2011 Author Share Posted September 18, 2011 I finally completed the two inside portions of the two "dead air cavities" and their function is compared to the "dashpot of a Corlis steam engine" and acting somewhat like an air spring to give the the woofer "push back" during certain octaves. Does anyone know if Mr. Klipsch incorporated such in his speakers? Or is this something Mr. Carlson at E-V designed into the Patrician IV?

barefootpoet Posted September 25, 2011 Author Share Posted September 25, 2011 John, today I caulked and prime painted the inside portions of the bass horn assembly pictured in the previous posts. The plans really made clear that the enclosure must be air tight. I'm now working on cutting the intricate details of the back overlay (part 21) that will form the back part of the speaker enclosure. I'll have to admit that so far this has put my novice wood working skills to the test. Quote Link to comment Share on other sites More sharing options...
JJkizak Posted September 26, 2011 Share Posted September 26, 2011 Way back in the 50's I used to go to a movie theatre that played music prior to showing the movie and the system was just outstanding. I don't know what brand it was but it might have been EV. I don't think Klipsch would have been that early. JJK Quote Link to comment Share on other sites More sharing options...
barefootpoet Posted September 26, 2011 Author Share Posted September 26, 2011 Interesting that you mention that, JJK. The EV Patrician in many ways to me does seem like a hybrid PA speaker. Not that that's a bad thing however EV's forte was (still) public address and auditorium systems. Quote Link to comment Share on other sites More sharing options...
John Warren Posted September 26, 2011 Share Posted September 26, 2011 The exterior grilled decorator cabinets were beautifully designed by EV. The Patrician and Georgian used similar techniques to hide the plywood horn structures from view. The guy that owns this one runs a place called Audio Ventures in Waukesha, WI. His shop used to be located at West Allis, WI which I visted a couple of times when I lived in the area. Quote Link to comment Share on other sites More sharing options...
barefootpoet Posted October 12, 2011 Author Share Posted October 12, 2011 Do you think this 18-inch driver would be a good choice for a Patrician enclosure? Seem to match up fairly well with the 18 WK Eminence Delta Pro-18C 18" Driver 4 Ohm Long throw subwoofer for small vented cabinets. Oversize top plate and large pole vent help keep the voice coil cool. Recommended enclosure size: 3.0-10.0 cu. ft. Specifications: Power handling: 500 watts RMS VCdia: 2.5" Le: 2.65 mH Impedance: 4 ohms Re: 3.8 ohms Frequency range: 35-200 Hz Magnet weight: 67 oz. Fs: 27.23 Hz SPL: 94.4 dB 1W/1m Vas: 17.26 cu. ft. Qms: 13.24 Qes: 0.32 Qts: 0.32 Dimensions: Overall Diameter: 18", Cutout Diameter: 16.57", Depth: 8.13".

I would forgo the unneeded power handling for a wider frequency response and better SPL. also,,,,youprobally already know this...but your going to habe to modify thecrossover to account for the 16 ohm woofer that you are not going to use.

barefootpoet Posted October 25, 2011 Author Share Posted October 25, 2011 Thanks for the advice, Speakerfritz. I did think the power rating capacity was a bit much on this Eminence speaker for a folded horn application but the "long throw" feature seemed ideal. It is interesting that the EV 18WK was 16 Ohm but had a 3.2 DC rating similar to a 4 Ohm speaker to pull more power from the amp. Quote Link to comment Share on other sites More sharing options...
barefootpoet Posted October 25, 2011 Author Share Posted October 25, 2011 Thanks for the tip, Speakerfritz. I did think 500 watts was a biiiit much for a folded-horn application. I did like the "long throw" feature of moving air through the column. Also the EV 18WK was 16 Ohms but had a DC of 3.2 similar to a 4 Ohm speaker to pull more power from the amp when needed.

barefootpoet Posted November 25, 2011 Author Share Posted November 25, 2011 Update; I've decided not to continue the Patrician due to me discovering that I simply lack the required skills. But it was enjoyable trying nonetheless. Quote Link to comment Share on other sites More sharing options...
