About a month ago I started a thread to gather info about building a 4 ohm sealed 410 cab. That thread is here, for anyone who is interested... http://www.talkbass.com/forum/showthread.php?t=723707 To summarize, I was looking for the best 16ohm 10" driver to load a sealed 410 cab for a 4 ohm total. I'm looking to build a cab that comes out sounding like 1/2 of an Ampeg 810 fridge. Basically, my goal was to create an Ampeg SVT-410HE that is 4 ohms (Ampeg only builds that cab in 8ohms). After some discussion on that thread, it seems that the best candidate would be the Eminence Legend B810. Here's the link... http://www.eminence.com/speakers/speaker-detail/?model=Legend_B810 The only problem: Eminence doesn't build a 16ohm version of this driver. I emailed Anthony at Eminence asking what it would take for them to make a run of 16ohm Legend B810 drivers. He said "an order of 100 from an individual." A couple of people suggested, on my previous thread, that we should look into doing a group buy. So, let's see how many people would actually be interested in putting money down on this, assuming that Eminence would be equally interested in 25 orders for 4 drivers. That would mean 25 individuals (me and 24 more people) would eventually have to put money down with Eminence for 4 drivers. PLEASE DON'T BUG ANTHONY AT EMINENCE ABOUT THIS. If you think you are interested in being part of a group buy, indicate your interest by responding ON THIS THREAD and NOT to ANTHONY or anyone at Eminence just yet. Let's start by seeing if we can gather up 25 people interested in 4 drivers each, and then we'll work on moving forward from there. The first step is to convince Eminence that it's worth their effort to build this driver. The second step would be to arrange an advance purchase. We can probably move forward on the assumption that if Eminence put a 16ohm version of the B810 into production, it would be the same price as the 32 ohm version. For the record, if we manage to convince Eminence to do this, I'll probably have fliptops build a cab for me. Here's their link... http://www.fliptops.net/catalog/product_info.php?cPath=61_82&products_id=448 I have no financial stake in this. I don't work for Eminence, Fliptops, or any other music industry manufacturer. I'm simply a guy looking to build one cab for my personal use.
