    I just finished building my MTM towers using the Stryke sa071 and sa-tw1 drivers.. have a look at them here. There are some large pics so 56k beware.
    Total cost for drivers and crossover = $95.

    I like the final picture; it looks very nice. I'm inspired to build something [​IMG]

    What's your opinion on the sound? (I am the designer of that particular Stryke kit btw, so be nice [​IMG]). I'll admit that I found the tweeters were fairly difficult to work with.

    Karl,

    Great looking cabinets. If you don't mind my asking, what compressor and spray gun did you use?


    Mark,

    Nice to see you around here again! Don't let Hank be too much of a bad influence. [​IMG]

    I think the sound is great.. but obviously the weak point is the tweeter. Highs are not quite as crisp and clear as they could be. Mark, have you tried using the SA071's with a different tweeter?

    My compressor is nothing special.. just a 15 gallon 4.5HP porter cable. I picked up the porter cable PSH3 gun to go with it. The compressor is a little under-powered for what they suggest but it worked out fine for me - it let me apply the paint slower so I had less chance of getting too much paint on and causing it to run. The enamel I used is great because I only needed one coat and it looks like I used about 3 or 4.

    Thanks for all the compliments!

    Wow I think you did a great job. I've always wanted to build my own speakers...but I never have. I haven't really had the time eather. I travel a lot for my job. But I was super impressed with the final result. Love the yellow/black combo. Mike D

    Karl, LOVE the speakers! The yellow of the drivers and the blue of the speakers makes a GREAT combo! I was really thinking about getting the same drivers for my computersystem, but I figured the shipping/duty/brokerage to get it into Canada would up the cost and make it more expensive than it should be. Awesome work though!

    WOW! I have got to build a pair of those. I am scared though, because I know nothing about crossovers. Is there a place I could do research on crossovers so I can try to build my own 2 channel speakers?

    Nice work Karl.

    I figured I'd post an update since I'm actually working on these projects right now. When finished I will have a small bookshelf 2 way, 13"H x 9"W x 10"D. There is a bookshelf MTM, 21"H x 9"W x 10"D. There is also the tower version of the MTM that measured 42"H x 9"W x 14.5"D. The tower is a vented enclosure and has good extension down to 30hz.

    The 2way Xover is finalized. I should be actually be finalizing a revision to the Xover in the MTM shortly, hopefully this week if time allows. I'll be trying to keep as many components the same as possible for those who have already built these. I'll be doing something similar to the tweeter section as in the revised S1 crossover used in a standard 2way with the SA071 and SA-TW1. The tweeter tends to sound much better with this 6th order filter.

    As an upgrade for those who want even better high end response, I'll also be doing the same design with the Seas 27TFFC tweeter. At $26.50, this is probably one of my favorite low cost tweeters, and a great upgrade to go with.

    The center channel will be similar in shape and size to the one I did here with Vifa drivers seen here:

    [​IMG]

    Once the Xovers are finalized, these will all be offered as kits with or without prebuilt cabinets, and also as completed speakers veneered and assembled.

    As a side note, this will be our new entry line of speakers. The next step up will be similar cabinets but using the Peerless HDS 6.5" mid and the Vifa XT tweeter. The top line will use Seas Excel mids and tweeters and cabinets will feature solid wood fronts and/or sides.

    John

    Hey John.. couple of questions:

    Are you going to be using the same MTM crossover that I used for my towers? And any idea when you'll be posting the new designs?

    I've still got enough drivers for a set of surrounds and a center, so I'm very interested in doing the 2-way bookshelf and the sealed MTM.

    That is a very cool color scheme with the yellow cones. Great Job...

    John,
    Where do you intend to xo the XT25 with the HDS 6.5? Even though it has a low Fs, I've found higher xo the better (^3K) or lower with steeper slopes (4th order +). Although you probably already knew that [​IMG]

    Hi Chris,

    I'm not positive where I will do the Xover yet. I need to do some polar plots to determine it. The 6th order filter on the new S1 Xover works out very well for our TW1 tweeter. It is possible I may go as steep as 6th order on the XT tweeter. I am also now thinking of switching to the Vifa DX tweeter instead of the XT. I need to play with both of them for awhile to figure out what I really want to do. I built a pair of enclosures for an MTM using these drivers this past week. Hopefully I'll be able to come up with something at least preliminary this week.

    John
