    Looking for someone that knows the designers of the L1/2/3/5 & 7.

    What Iím trying to find out is, who were the cooks in the kitchen so to speak with this series. I believe this was the last series to be US designed and, US made back in the 90ís. I would think, that there would be some very talented and reputable engineers on the design team.

    The manual on the L7 had a three page addendum that discussed bi-amping and bi-wiring in good technical detail. What ever mode you decide to use is a supported method.

    If you'd made it through the entire '90s L-series thread you'd have seen reference to the L7 supplement, T-dome's instructions covering the famous blue wire, and you would have met Chris Hagen, a member here who was the designer for that series and who comments in that thread. Most recently Chris was brought back into the Harman family as designer of the new L100 Classic.

    It's a long thread but chock-full of meat for L-series owners and enthusiasts.

    BTW, I don't know what an L2 is???

    Enjoy.

    Some L series speakers were designed by David Smith.

    "David was responsible for such systems as the L15 and L46 for the Consumer Division", so the list might include others not specifically mentioned.

    Btw Lenbrook Industries, mentioned in attached pdf about David Smith, owns NAD, PSB speakers, etc. and also distributes in Canada B&O and Tivoli.

    There's another interesting and long interview with him on TNT-Audio but copyright issues prevent me from posting it here since it wouldn't be JBL material posted on a JBL related forum.

    Small excerpt from that Smith TNT-Audio interview "In the last few years so much has moved to China that there are very few firms with real engineering or product development in North America, I now work in the digital cinema field for a firm in Toronto." Pretty sad.

    Happy new L7 ownerÖ..sorta

    Confession time. I had a chance to pick up a pair of L7 last week. for a great price. Iíve waited for years for a shot at a clean pair. I inspected the drivers all good. Take them home and set them up in my main theater room. While adjusting them I finally took notice that they are both left sideÖ.remember in Bugs bunny, before something bad happens, and the sign pops up ďmoronĒ. I didnít loose out money wise. I could easily part them out and make a healthy profit. SoÖÖ.

    #1. Does anyone have a right side cabinet that I could buy?

    #2. The only placement I have is between cabinets. Itís a tighter fit and totally opposed to an optimal position. The base was boxy/boomy as I expected. I tried a different config where I set
    the
    L7 as small and crossed at 70hz. My twin RBH 1010-sen/reference subs are mind altering. I toed them in slightly, then configured my unused two channels on my massive Crestron 7x200 for bi-amping (I took a beating for mentioning bi-amping on another site. Itís a supported configuration).

    The result was so amazing. Massive soundstage, beautiful imaging and as clear as any speaker Iíve ever owned. My L-200t became second fiddle by a long shot. Name:  3EAEB6B0-5B27-4026-AAFD-5B3F65BBA2D5.jpg
