    I can upgrade the 7s... you can email me [email protected] to go further on those!

    I would probably still stack them and do point to point wiring - why not right? :)

    Excellent job on those LSi9 crossovers. I love the use of the all-thread to keep everything clean and orderly.

    Looks nice. Those for a customer or for your personal evaluation?

    Thank you sir!

    These were for a customer!

    We are constantly trying to fit nicer stuff on our Fortress stack! I think after seeing the 400v MR we may try sticking them on there every once and a while! :)

    Those look great! I think I have finally figured a layout to work the ESA into my tweeter circuit and make it all fit through without making them even taller.

    Thank you sir!

    That is going to be a massive crossover...

    Are you changing the 260uf with ESA as well? That has gotta be massive

    In that case, I'd recommend going external.

    No...not doing the LF that way. Just going to do a bennic with an ESA by-bass similar to your pictures. I looked at DarkNight's mod where he did a replacement, but did not want to spend that kind of money at this time. And I still am not a fan of the LSiC so I grabbed some LSiM703/706c to try so not even sure why I am doing this, other than I had already started the process and it should be a fun project. Not looking forward to stuffing something into the LSiC space....that is small. I was leaning towards the LSiM due to the 8 ohm rating and an AVR configuration, but I am seeing some other threads questioning the 8 ohm AVR friendliness of the LSiM line. I have the Fortress 9's hooked up to a NAD 2600 and they sound great. Hope to get these 9's modded over the next 2 weeks and see how things go from there.

    The ESA would definitely be external with the 260 - that would be probably 3"x3"x7" of just caps!

    Make sure you post pics of the ESA mod, it will be nice for sure!

    Gotta <3 them VR3 mods....

    I was listening to my SDA's today (stock xover) vs the VR3 LSIM 703's and they can hang.... The tweets in the 703's sound better than the SDA's but SDA's just push so much more air on the mid and bottom... I should probably get the xovers in the SDA's to you sometime soon tho... but they do sound very good even now.... I am going to check them to see if they were upgraded...

  • Trey! Its awesome things are going well! Dude those mods are sick! What wiring you using for those p2p connections?
  • VR3VR3 Posts: 22,246
    Thanks man!

    90% of the PTP connections are from component to component, infact - all of them are except for the +/- from the plate and from one side of the lead on the 1uf. Those wires are a generic stranded 16 awg OFC. The wires from the crossover to the drivers are Supra Classic.
