    Actually, not really. The bass is great with the drivers half towards the floor.

    Ive always been surprised how the mods sound free air, when you leave the room, you can hardly tell they are free air versus in an enclosure. The bass is not as forceful or the impact but it is there.

    They wont fit inside :) Some people also feel external crossovers sound better since they are not exposed to much vibration... ymmv

    Bad news ,The fedex plane carrying my xovers that Vr3 built crashed around a week ago.
    Good news though , the only two box's that were retrievable at the crash site were mine due to their packaging.

  • ptrooperptrooper Posts: 233
    Ok. Got a lunch break in and installed these x overs. Thank you again to Trey and Dave for your excellent services

    The Notorious Larry's Rings. I find them to be even better after glueing them in, more so in the SRS's.I just wiped power grab along the edge internally making sure that none enters the threaded area.....so how many inch's of steel are in the SRS'S installed with theses rings..? I lovem.

    I thought the factory enclosures could possibly benefit from a front to back cross-brace. Will you reinforce the area you cut out?
    Looks great.
