  • Willing to do some modeling for the Tang Band W6-789E 6.5" midbass (BF Specials)

    The Tang Band W6-789E is a unique, high-sensitivity (at least 91 dB/2.83 v on IB) midbass driver. Will be on sale for only three days (11/27-11/29) for less than half the regular price---a steal at $20! I once modeled TM 2-ways a while ago, one with the Vifa D26NC55 and the other with BG Neo3PDR. Both builders were very happy with the results. This midbass driver requires rather large a box for a vented alignment, but 0.5 cu ft per driver is not out of the question though 0.7 to 0.8 cu ft is better.

    If anyone's interested, I am willing to model up a crossover for TM and MTM with a high-value tweeter. MTM will have anechoic 92.5 - 93 dB system sensitivity even with BSC built in. A tweeter in this system should be at least 94 dB sensitive. One that I'm thinking of is the Vifa BC25SG15-04 (non-shielded version is BC25TG15-04). This is basically a ferrite version of the Vifa's new, popular neo tweeters. 2 kHz LR4 shouldn't be a problem.

    EDIT
    --------------------------------------------------
    In case you want to go directly to design details:

    MTM with SB29RDCN-C000-04

    MTM with Vifa DQ25SC16-04

    Horizontal MTM for Center Channel with SB29RDCN-C000-04

    TM with SB29RDCN-C000-04

    TM with Vifa DQ25SC16-04

    Hey thanks for the reply. Thats good news. I am going to build a pair then and ill post a pic when finished. I think i`m going to use the vifa tweeter as funds are tight.

    I`m dragging this one back to life. I have decided after a long lay off to have a go at these MTM`s and am wondering if anyone has built any yet? I would also like to thank Jay for his hard work in providing these designs for us poor crossover incapable folks!Please let me know if you have tried these designs.

    Thanks! I'll be interested to see what you changed. I grabbed 4 of these woofers when they were on sale and have yet to hear anything but glowing reviews of them. But that makes me wonder why we don't see them used more by folks here on the PE forum.

    There is a commercial system out there using an MTM arrangement with a B&G Neo 3 that sounded very nice. I believe they are in a quarter wave cabinet. I was surprised at the bass since someone had said not to expect too much. They sounded clear, fast and deep.

    I'm glad to hear you are pleased with them, especially after living with them for so long. I hope to finally build one of these designs after the holidays, but need to get rid of some other speakers first. Did you make any changes to the crossovers?

    I have been enjoying the MT version of these with the SB29 all year as my main music speaker. Now I am seriously considering the JKims MTM design for L/C/R HT duty.

    Would it be to much to hope for another great deal on the 789 like last year? Come on PE! I need 6 of em!

    Is There an Impedance Equalization circuit need for this speaker since being in parallel in the MTM

    If you mean the "Speaker Gallery", he might not have pictures. If he has pictures, they can go there. That is mainly for 'finished' projects.

    If you mean the "Project Showcase", then he has to submit them to Parts Express to see if they want to add his projects, and that he has no control over.

    BTW- the way you right your messages is aken to the spam-bots, so a lot of people may not even give you the time of day.
    Later,

    These should be put in the project section for they are excellent designs are very worthy of being put into that section

    Hi Jay,

    I just became aware of this thread...

    Did you ever complete the MTMMM or MMTMM variation? Either would be great as there aren't enough high efficiency, benign impedence, low cost designs around. The corresponding relatively large cabinet is a small price to pay for all of the above.

    With The FR of these Tang Bands with the SB tweeter in the MTM , I am surprised that they were crossed over at 2,5 Khz or 3Khz and using a foil air core for them and what software did you model them with, for I am looking to get some modeling software that allows as many variations possible instead of the known 2 ways and 3 way configurations. I do have to admit you did an excellent job on these designs. You got me hooked using them. I wish they would go on sale later in the summer.
