The 10" and 8" drivers used...Hello Rick, <br />The 10" and 8" drivers used here are all produced between mid fifties and mid 60'ies. These (motor-systems and phragms) are still basically identic, only notable difference is that the earlier 10" units (with brownish phragms, whizzerless, positioned 4 in row at the sides) has a somewhat higher Qm, whereas the later units is more edge-damped / lower Qm. (Later units, some whizzered, also have slightly harder pressed phragms, but with same mass or mass/diaphragm-area.)<br /><br />In the use here, the whizzers and various dustcaps didn't contribute to differences, as alle units was lo-passed at 750Hz. (With the 4+4 "bass" units positioned at the sides further lo-passed at around 200Hz.)<br /><br />There is not much to find on vintage Seas units on the web, but Troels Gravesen has additional info on his speakerbuilding-site: <br />You can read more in the vintage-section, under the construction "Blackcones", that puts a same type 8" (As seen near the white horn) to use in a resonnant cabinet. <br /><br />Best regards TorbjørnTorbjørn Liennoreply@blogger.comtag:blogger.com,1999:blog-2098337119765190876.post-20380290387998142722016-11-18T18:11:58.191+01:002016-11-18T18:11:58.191+01:00Thanks Thomas, and Torbjørn,

I wonder how you configured where to put the whizzered ones and non-whizzered ones on the baffle.. Or maybe it was a random placement.<br /><br />I thought the horn was familiar. The late JMLC would be proud to have heard this system. Martin (Azurahorn), Bjørn, and Lynn should see this blog post. Lynn should also see Thomas' previous PP DHT posts.. Those pro Be JBL's sounds like a good match for the horn.<br /><br />Congrats on a fine on the "left field" Flower Power OB/Horn system. <br /><br />RickRicknoreply@blogger.comtag:blogger.com,1999:blog-2098337119765190876.post-19693319722046859892016-11-17T12:33:34.897+01:002016-11-17T12:33:34.897+01:00Hello.

Most units produced later would simply have been to heavy, and so more bandwith-limited.(The cone sections were at all times driven only by a modest 1.5W, by Lars' SE 2A3-amplifier.)<br /> <br />Next I want to thank Thomas Mayer for his coverage in writing and pictures, both of the ETF, and of the Norwegian system: So nice and professional work, Thank You! And thanks to the rest for making ETF such a great event.<br /><br />The white midrange-tweeter-horn used is of the late Jean Michel LeCleach-type.If I have understood right, it was a collaboration between Lynn Olson, Bjørn Kolbrek, and Azurahorns. Its a 425Hz modest Hypex-type horn, ecpecially develloped to fit the Altec 288. In the ETF-setup, a beryllium-phragmed Neomag.-driver was fitted via a thin adaptor to the throat; the JBL-2435HPL. It seemed to work fine.<br /><br />See you!, Best Regards Torbjørn Lien - Norway <br />Torbjørn Liennoreply@blogger.comtag:blogger.com,1999:blog-2098337119765190876.post-72641763060351555932016-11-16T16:56:51.825+01:002016-11-16T16:56:51.825+01:00Hi!

We have been as impressed with this system as anybody else, as actually it had not really been listened to before we set it up on Friday. However, it had been carefully conceived and planned by Torbjørn since before the previous ETF. Some time and experiments were needed before we settled on the best choice of HF system, crossovers etc. in place by Saturday afternoon. Thanks to Bjørn Aaholm, Lars Tørressen and Charles King for all the amazing tapes we got a chance to listen to.<br /> Because of unexplained response differences on swapping the LF and HF amps in the bi-amp setup, we ended up running Lars' SE 2A3 amps on the LF section (2 outer rings of cone units) and they never seemed to be running out of power, even when the system went quite loud and with a lot of bass. Also, the center LF dipole was found mostly unneccessary for sufficient bass reproduction. We brought it along almost just in case, but it was hardly used at all during the ETF.Thomas Dunkernoreply@blogger.com
