    In flux... KG 2.5's (titanium tweeters, rebuilt x-overs) standing by to be replaced by re-built Epic CF-2.
    Powered by a Sony receiver, it's just easier to deal with than the '61 H.H. Scott 222C, sadly.

    Chorus 1 front port mods

    I'll also echo the tag board/construction paper method. I've done this with my CF2's and an old Kustom 4x12 cabinet when I was playing bass and gigging a bunch.

    How much toe-in do you use

    Well, disregard everything I just posted... One speaker was wired backwards. Effenheimer! Nice to finally have some bass, though.

    That's probably not far off from where I have them turned right now. Maybe I'll post a picture some day. 😉 I'm loving how these things throw sound through the whole house without getting that loud. The horns could probably use an L-pad, maybe with some HF EQ to balance everything.

    I tried the CF2's straight-ahead, and it wasn't great, weird kind of hot-spot in the middle, and a bit of a 'head in a vise' hot-spot right down the middle. Then tried them toed-in, pointing directly at the MLP, the hot-spot in the middle sounded better, but it was even more of a 'head in a vise' affair. Now I have them toed-in pretty severely, so that the horn directivity on both speakers covers both the main and side sofas in the (small) living room I have. Things are much more even-handed now. Sound got even better after letting the cheap sony HTIB receiver run it's calibration sweeps with the supplied microphone. Yeah, it's not strictly hi-fi, but it's working pretty well on my budget (and with small children, I'm definitely not putting the vacuum tubes back on display )

    did those Omni mounts line up with the holes in the bottom of the 2.5's, or was there drilling involved?

    HH Scott 222c Power Tubes Issue....

    Not really that, more of the modern YouTube type. Flat-Earther and all that stuff. Basically, one of those guys that thought he knew something but was missing a little bit of basic physics. There's a lot of garbage out there, and a little bit that isn't garbage and will piss a fella right off.... Anyways, back to tubes.

    What would you do with these 12"ers?

    Edgar, that's about what I was thinking it would be.

    Let's riff on 'open baffle' vs 'infinite baffle' for a minute. any real appreciable difference? Maybe it's my perspective, when I think 'Open baffle' I'm thinking of a board with a speaker in the middle of it, usually reserved for Lowthers or somesuch. "Infinite Baffle" makes me think of what JohnA posted.

    Seismic Audio Earthshaker. Allegedly a stronger motor version of their Richter model. Infinite baffle into the basement has crossed my mind. (Attic it's right out, there's a good 2' of fiberglass and blow-in insulation up there). Speakers in the cream Fender clone are Carvin PS12B, some kind of Eminence re-branded. Beta, I think.

    Top plate looks to be fairly thick from the picture I took when I re-wired the cabinet for a 2-ohm load might well be as thick as the magnet.
  14. * Piston Diameter = 260.4 mm * f(s)= 37.68 Hz * R(e)= 6.54 Ohms * Z(max)= 43.48 Ohms * Q(ms)= 4.569 * Q(es)= 0.808 * Q(ts)= 0.687 * V(as)= 129.400 liters (4.571 cubic feet) * L(e)= 0.51 mH * n(0)= 0.82 % * SPL= 91.22 1W/1m * M(ms)= 54.87 grams * C(ms)= 0.33 mm/N * BL= 10.25 Xmax = unknown, but I'm sure there's plenty. 4 of these have been living in a Kustom cabinet I was gifted, loaded with the drivers. I played many 2-4hour gigs on bass guitar before I made some ports out of black heavy paper. 700 watts at 8 ohms below cabinet resonance and I didn't ever hear any farting out noises. So, what could these things possibly be used for? all I can think of is building tapped horns between floor joists. Properly calculated ported box for 1 driver = 23.3 cubic feet. Wife Acceptance Factor = 0, so it doesn't matter that it would tune at 23Hz and -3dB is at 16.7.

    Yeah, one of those "I'm a single guy with a house and some dude from my church needs a place to live for a while" things. I learned so much about Nibiru and chemtrails while he was here... 😑
