    Prob would suggest iLoud MM or Vanatoo Transparent Zero. I am probably selling one of the two at some point soon, hah.

    JBL 4628 $400

    I see JBL sometimes with a “B” at end of model number like 4638B. Is there a difference? Should I avoid non-original surrounds?

    Yes, I saw @purr1n ’s JBL thread.

    Cabaret series were a PA line. Which means the high end is going to be rather hot for small indoor space.

    The A and B were JBL's way at the time to signify a slightly different model. The specs for the 4628 and 4628B look almost identical though.

    Non-original surrounds on old JBL speakers is not a sin and almost means they are repaired and will last longer. Original NOS surrounds might be hard to come by for that particular model.

    Thanks Azimuth. I messaged the seller to see if still available.

    The bright highs shouldn't be too big a deal. They'll be used in the living room (plenty of off-axis) for mostly television. I'm fine with using equalizer. And bass extension is not a concern since I live in a townhome (shared walls). I'm using high pass filters or open baffle speakers to mitigate issues currently.

    Yeah, Purrin 's JBL thread made me click on the CL ad.

    Any advice for dealing with binding posts that don't provide a snug fit for banana jacks?

    On my Schiit Aegir, the positive terminals on both channels seem to be slightly bigger than spec, such that none of the banana jacks I have can stay in securely. The negative terminals on the other hand provide perfect fits, as do my terminals and speakers, so I'm sure it's not just the jack at fault. I haven't tried the more expensive locking jacks yet, cos I don't know if they are made to handle slightly defective terminals.

    Unfortunately spades are out because I switch between amps, and my other amp has too little space between terminals to fit most spades, otherwise I would have just done that and called it a day.

    torque your bananas to allow a better fit - just do it in small increments so that destruction does not ensue

    Thanks @dBel84. I have tried that, and it works until I switch amps. Kinda frustrating to do that every time so I was hoping for a more permanent solution, but I suppose sometimes you just have to take the lumps

    using something like this might help mitigate the constant need for change

    or if you did need to add spades to one end

    @Friday I highly recommend trying the locking banana plugs if you cant use spades. Solved all my problems with one set of cables feeding different pieces of gear. Only challenge, they are a bit longer than some banana plugs.

    Try the ones from Blue Jeans cable: https://www.bluejeanscable.com/store/speaker/index.htm

    Just get rid of the bananas. Use spades, actually bare wire is the best connection. Just better sound.
    Bananas make sense around measurement apparatus for the convenience factor, and even there sometimes these are limiting signal transmission.

    Agreed that they don't help the sound but if you switch amps or speakers out regularly bare wires are a huge PITA.

    I’ve heard that if you have to use some type of connector use something compliant like copper and then tighten it enough so the copper deforms a little for best contact. And that got me thinking why not use something to fill in the gaps like thermal paste does for cpu’s/gpu’s with heatsinks. The effects for those are not subtle at all, so who’s gonna coat their cables in liquid metal? Just leave a little length to restrip since it will eat away bare copper… but first world problems right?

    At that point just solder the wires directly to the speaker. The solder is the "thermal paste"

    I guess but removing is even more of a chore then…

    I did tin a speaker cable once and the results were not good. Cable looked fine but made no contact lol

    Bare wire or spade well tightened makes the copper (most soft metals) cold weld on tiny areas - that is where most of the conduction happens, at least with large current and low voltage. Only so much is needed, as compared to the cable cross section the bare wire-end or a spade is quite large.
    Bare copper and most of its alloys gets covered with a thin but rather porous layer of oxide over time (main reason for the gold and silver etc coatings). Not great for conduction of current. Weak contact force will not cut it, a loosy-goosy banana might not be enough to significantly scrape off the oxide layer.

    Maggies have an allen screw that secures the banana which is a major PIA when switching out cables or speakers but does offer a secure contact point

    RE: JBL 4268 $400

    Seller got back to me and said they are “B” versions. He also kindly notes that one woofer is slightly different color which perhaps could be sun bleaching. What do you guys think? Would mainly be a tv stereo upgrade (avr) due to high efficiency. I listen to music on my Manzanita Ultras so not worried if I dont love the JBLs for music. My current tv speakers are Cambridge Audio Aero 2 (using a high high-pass filter).

    RE: 4628

    Drivers. Mid runs full range, hmmm. Minimilastic approach, detailed in Marv’s thread.

    4268 vs 4698. The enclosure is minimized (not optimal) w 4268. 4268 is about 100lbs so 4698 like 200lbs? Damn

    http://www.audioheritage.org/vbulle...urve-for-Zilch&p=117421&viewfull=1#post117421

    edit: The 4268 doesnt have alnico magnets on woofer unlike 4698. The woofer is also “crossed over” higher but drivers are smaller. Only tweeter is same.

    Messaged back to buy. Fun.

    Another measurement from linked thread above.

    They will be placed near back wall and likely on floor so I might hear more warmth in comparison. There is also a high frequency controller on back.
