    Re: $500

    Must be he wanted to monetize the design, although it uses off the shelf drivers. Good luck with that, whatever...

    Re: Gowa's experience

    I've never understood people's desire to keep their DIY projects a secret. Unless you plan on making the project a commercial design, why not share the design with others?

    Color me confused...

    Re: $500

    I had the pleasure of hearing the Seas L18 matched to the Peerless HDS crossed at 1.7 just a couple of years ago. They sounded amazing with tight bass and very clear vocals. Sadly, the guy wouldn't share his crossover.
    Mark's ER18DXT looks interesting. Also, the Seas Indun looks good. I may be wrong but I think Zaph mentioned that he may work up something with the Seas U18RNX/P.

    So, you have been into speaker building for a while. You have examined Zaph's site closely, as well as Tony Gee and Troels Gravesen. You enjoy 2 way stand mount speakers sans subwoofer.

    You have $500 bucks you are dying to spend on your next speaker build. You've built the extremon from Tony Gee...



    You've built the Zaph L18:



    And you've built the Zaph SR71:




    What is your next project?

    Do you build another L18 again, cause that is a really cool speaker? Do you do nothing and save up for the Zaph ZD5 in a ported floor stander, or the Troels CNO's? Or, do you wait for your friends on the PE board to suggest a really cool design that fits in your budget and sounds better than anything else you have built??

    Come on... everyone has an opinion.. even you.. feel free to share.

    Thanks!
    It would seem that you're already an accomplished cabinet builder, so this might just be something interesting and is "just" within the budget:

    I've got a pair and they certainly are good, in fact they're reference quality and a pretty good deal for what you end up with. They use the Peerless HDS tweeter and a proprietary XBL2 midwoofer.

    Best Regards,

    What was missing was having fun listening to a speaker. The SR71 was good, but I found it bored me after a while. Also, I think there are speakers out there that do better with voices (both male and female). The ZD5 had me interested because it is still a zaph design, but steps up to better drivers.
    you are losing the voices by playing yours woofers too low. I repeat every 7 inch speaker design will improve mid/tweeter sound (voices) by hi passing it 20hz to 80hz above f3 point. you hear congested voices due to the lower bass being played through your speakers. By the way they look great I wish I could get mine to look as good as yours do.
    If you want a 2 way speaker to sound better (in the human voice range) the next one you build whatever design it is Actively high pass it 20 to 80 hz above the f3 all the voices will become clearer. You can do whatever you want with the bass you left out It is as simple as that.

    My own two cents...you've already built some great designs with good drivers(and done a beautiful job on them too)...so what's lacking? Maybe 2-ways just don't have the oomph you want?

    If you still have any of those designs you metioned why not buy another pair of the woofers, and make them a 2.5-way? You'll already know the qualities of the drivers your using, you can probably re-use most of the crossover parts in the new crossover and you'll get a more efficient and much cleaner-sounding speaker.

    It will mean designing a new crossover, but those are very well documented designs/drivers. PCD and the other FRC-tools are great once you get the hang of it.

    I started with an extremis-based two way (with seas 27tbfcg tweeter) which was great, but it's even better as a 2.5-way. No lack of oomph! :-)

    Grand Rapids, Mi... Kentwood to be exact. Where do you live? (sounds like a weird question since you already told me, but are you in GR or one of the six surrounding cities?)

    I built both of these 3-ways for under $500, they might give you the sound and build you want.

    ...
    You don't need the tent sale as much as you need the DIY meet. InDIYana was my first, and I found it a very enlightening experience - listening to 16 different DIY designs with an opportunity to talk with the designers about what they did to get the sound they achieved. You've auditioned many commercial designs, built several DIY designs, but have you ever auditioned DIY designs?

    My point is that a speaker is a combination of drivers, crossovers and enclosures. DIY requires selection of each, but the starting point is the drivers. You ought to listen to a bunch of them, rather than asking us which ones will sound good to you. DIY meets are a great place to do that.

    HAve fun,
    Frank

    I think that the overall sound can be better than what I've built before. I've never been attracted to the bottom end. I appreciate more vocal reproduction and imaging.
    I think what others are trying to say here, in regards to adding a sub, is that by adding a sub and high-passing the 2-ways you can reduce distortion in the 2-ways and achieve more of the clean, detailed sound you're craving.

    Re: $500

    So do I. This is hard to explain until you hear it for yourself in person.
    Those are focal mtm's they use a 900 dollar a pair tweeter they use 2 200 dollar 7 inch mid woofers.
    (note I did not pay 1700 for the drivers that is list)

    They play great to 60hz, and they cover all the highs. I run those subs from 45hz to 100 hz I run the focals from 100hz up. The sound is much improved. I have a lot of high end 7 inch speakers mtm's . Using
    scanspeak,
    seas,
    excell,
    Jordan,
    focal.
    All have f3's from 45 to 60hz. everyone sounds better crossed at 100hz to those 12 inch sealed subs. I have alot of problems conveying this idea. I believe every 7 inch woofer would be better off crossed 20 to 80hz higher then its best f3 rating. I have never heard a 7 inch woofer play to 35hz better then it plays crossed higher 60hz to 100hz. The trick is the subs used to under cross it need to be well above their f3 . the pair in that photo is nht1259 they f3 at 28hz I bandpass them 45hz to 100hz. the real bottom end is an IB run from 17hz to 50hz and i turn it off for music.

    I will tell you what whenever you build mt's or mtm's you have an invite to bring them to my home and hi-pass them at 100hz with my nht's playing 45hz to 100hz. phil
