    I am going to build a set on gimpods boards and keep the stock set for comparisons. Same goes for the tweets.

    I hope you have your tweeters and crossovers upgraded first.

    Inquiring minds want to know why?:redface:

    If you're gonna go all out, why bother with 30 year old electrolytic capacitors and outdated tweeters.

    Oh well I figured that out a long time ago.:razz: I was wondering if there was another reason considering John is doing something this big, :lol:

    Clarity MR's John??:smile:

    They are out of stock of the 12mr's I have been trying to get them for a couple of weeks now..

    Nothing but the best on these girls Larry. That's why I will be needing your help.:cheesygrin:

    I am looking at redesigning that crossover plate and integrating the tweeter array into a more modern look. I would like to get a finish like pioneer uses in the faceplates of their Elite line for these parts and also the adjustable foot system.

    Just to update... I have not had much time to devote to this project, but I have found a pair of speakers that most closely reflects the vision I have for the new cabinets...

    wow these KEFs. wish my Lsim707 looks that good on the side. I think the Lsim 707 has a better looking front though.

    Yep... I think a piano black baffle with that sexy wood finish backing things up would be sexy as hell. Looking at an urushi finish for the crossover cover and rings around the driver's outer edge to complete the look..

    Still trying to get some CAD plans drawn up for these, but I am useless when it comes to computers...

    Have you tried google sketchup? Its more basic but should provide a skilled carpenter enough of an idea to work with...

    Yeah... I have looked at it and still cant figure it out. The problem is maintaining the required 6.725 CF in a curved shape. The two things I cannot compromise on is getting the internal volume and the front baffle 100% correct. If either of those are off by the smallest of margins, this will be an expensive failure of EPIC proportion.

    Others have tried and failed because they tried to reinvent the wheel. I just want to make a better wheel.

    I will do just that sir^^^ It would also be nice if my fingers weren't so damn dyslexic today. The internal volume should be 6.375 CF.(lol)

    I doubt it.

    There is no guarantee that 6.375 was the ABSOLUTE OPTIMUM cabinet volume to begin with. We already know that the front baffle/driver spacing has a range of possible spacings, based on the 1B/1C front baffle vs. SRS 2 front baffle. The speaker you're improving probably wasn't "100% correct" to begin with, so making yours "100% correct" based on previous work may be a fallacy. The speaker you're improving was a compromise of a hundred different things, and they chose what they believed would work best at that time, with the tools they had, where they were, to make a sale-able product for people who lived in the 1990's. All that is different now.

    The downside here is that you don't have a team of engineers, top-flight computing power, and the capital to produce numerous prototypes for listening tests. I understand that there's an enormous amount of work that can be saved simply by copying the specs--but not the construction or the materials--of the previous cabinet.

    A bit of an update. The good folks at KEF have put me in touch with a prototyping shop out here, just outside of L.A. They do custom enclosure design for the big guys, including Infinity, KEF and several others, and their work is top-shelf all the way. I am supposed to meet with them in the next couple weeks and see what they can do to help move this project along. Hopefully they are willing to do nothing more than provide the blueprints for now.

    I will make those plans available to all when the time comes.

    Make sure YOU own the copyright to those plans, so that they can't jack you up about distribution of the intellectual property.

    When I first heard about this idea I thought great. I am and always will be a guy who favors wood over anything else. Just look at thos KEFs. As good as Vandersteens and DCMs are sock style speakers are a PITA if you have to work on them. If I had any real woodworking skills the fabric sides on the 2Bs would also be gone. Again not very fond of light oak as speaker furniture either. If someone could put a really nice bullnose front like my old Infinitys had and I think ARs or Advents back in the day.
    It's kinda hard to tell but sound aside I still think my long gone Infiniys SM112s were a good looking speaker both grill on or off.

    After speaking with the company out here that does this type of thing, we were unable to come together on a plan for going forward(not surprised. Due to the economy, and the lack of business out there for manufacturing large speakers, they don't have the CAD department they used to, and cannot spare a guy to do the work.

    I suck at CAD or anything else computer related, so unless I can find the support needed to put these plans together, I will be shelving this idea for a while.
