Ok.........what is with all this subwoofer delays? First I was told my Peavey ipr2 7500 would be delayed......now my drivers are being delayed until early to mid-April? What the heck? I had to wait almost three months for my JTR S2.........now this!!! From Rory Buszka: Dayton Audio
Gentlemen, I have a bit of news.
We are expecting the arrival of the Ultimax 18" driver to be delayed until early to mid-April.
During our in-house testing of a prototype unit, we discovered a reliability issue with one of the crucial adhesive bonds within the moving structure under certain conditions. We have since resolved the issue with our build house (by increasing the amount of epoxy at this joint and upgrading the voice coil former wrap to resin-impregnated glass fiber, and also changing the tinsel lead wire dress to a more robust loop weave that allows for more travel with less strain), and extensive reliability testing of the new prototype beyond the point of abuse has shown the problem to be completely eliminated; the affected adhesive joint is now practically indestructible, and the "weak link" is now the thermal limit of the voice coil. However, the resulting delay from addressing this issue caused us to miss bringing the driver to production before the Chinese New Year holiday, when manufacturing in China shuts down for nearly a month. As a result, production cannot begin until late February, and the speed of ocean shipment accounts for the rest of the new ETA. The product will be available for shipment as soon as we receive it.
We would much rather provide a high quality product later than a poor quality product sooner, so this delay was unavoidable in our view. However, it means that some of you who have preordered UM18's will be waiting longer for your production drivers. Some of you may wish to cancel your preorders or choose other drivers, and that is something we are prepared to accept. The excitement around this affordable, high-performing driver has led to a large number of preorders, but we at Dayton Audio are still confident that this will be a spectacular product once it is in-stock and available.
Also, while we have not had similar trouble with the other Ultimax models (since the Ultimax 18 undergoes quite a bit more VC travel and mechanical stress), the lessons learned in the development of the Ultimax 18 will flow down to future production units of the other Ultimax models, to increase their mechanical ruggedness.
Thank you all for your interest in our Ultimax series, and we look forward to serving you with more top-quality loudspeaker products in the future.
