    $100 planar / ribbons... who's the class leader?

    So, I'm working on a slim MTM tower with SB15NRXC30-8 in a Kittinger MLTL. My original plan is starting to encounter some scope creep, and I've decided to just embrace it. Out with the XT25, in with some flat diaphragm.

    I'm not set on a crossover point, but I have a feeling I'll need something that can at least do 2nd order @ 2.5khz.


    My knee-jerk reaction would be to grab some Neo3 PDRs, but I've been out of the loop long enough that there are a number of new product lines and I would not want to miss out on the new hotness. The Beston RT002A looks super nice for today's sale price (even if they're at the edge of my arbitrary 2.5khz limit). I may grab a pair of those on a whim regardless.

    The Beston has a hump from 2-3k before roll off. I think that's going to allow an electrical XO that is significantly higher than acoustic.

    Good call Steve! The HIVI RT2 models would do it. They are good to about 2.3-2.5k range.

    Thanks for clarification - also...well done on the impulse buys!

    Yeah, that design is open-back.

    I pulled the trigger on the BGs...and also the Bestons and Fountek FW146 because I'm evidently short on impulse control. I'mma be set on projects for a good long while. I'll definitely have something new to bring to InDIYana. Maybe a couple of somethings.

    Jim Holtz's Bordeaux uses the AST2560 and I THINK he mentioned not having to make a rear chamber.

    Troels Gravesen, on his site, likes the HiVi RT2H planar, which is $100. I am not sure how low it can cross, have never used it. It looks a lot like the Beston visually. He speaks of it having electrostatic clarity.

    Those Fountek 146 mid woofers look pretty sweet at that price.

    I've used the BG Neo3 in two builds and its about to go into my biggest and most ambitious to date. Fantastic tweeter.

    Beston crossed at approx. 2.5k 2nd order LR. My every day speakers.

    Oook. No rear chamber on the Aurum Cantus. I guess I could put something together with 3D printer, but that's more than I want to deal with, and the MLTL doesn't leave a lot of room behind the tweeter for a sub enclosure. Neo3 it is I guess.

    Hmm. On the 2560, do you need to compensate for the 7khz dip? They're more expensive, but it just means I wouldn't impulse-buy the Bestons (which would just sit on my shelf for years anyway).

    I like the look of the Dayton, but it just doesn't have enough sensitivity below 3khz. If this were an active job or a 3-way...yeah.

    I used a super tweeter with the AMT3-4.

    I agree the 2560 is a good recommendation, but it's 1/3 again more expensive and definitely over $100.

    Later,
