    Nice looking cabinet. I'd like to know more about the drivers.

    Also the horn. Did you make it? Based on what drawings?

    Thanks for the pics.

    Thumbs up Cool !

    Hi Kelly

    Very Nice !

    Glad to see some construction going on in the prairies .

    Have you already made grills ? If so , how about a pic with the grills on .

    ( I guess you gave up on making those Pi boxes sound acceptable - yes / no ? )

    Pi speakers

    "(I guess you gave up on making those Pi boxes sound acceptable - yes / no ? )"

    Thought I better answer that one right away. I always liked some aspects of the Pi's. The model I built wasn't to my taste and in retrospect I know why. It was the Eminence horn/driver combo. Even the JBL 2421 didn't sound anywhere near as good on the plastic horn as it does on my homemade jobbies. Also I'm currently using Waynes recomendation of 4 cu' for the 2235H instead of JBL's 5 cu' which I tried in the previous incarnation of this design and was very unhappy with. The 4cu' cabinets have much tighter sounding bass IMO.

    Hi Kelly

    Is that plastic horn made by Eminence ? Do you know the model number ?

    Salvaging the Pi :
    - Now that you've got some experience in horn making - maybe you can make up a horn to replace the plastic "jobbie". Add some Altec 902-8b drivers or even B&C DE-25(s) and redoe that crossover and you've got a completely different beast.

    - Also; It seems that your recently stated listening tastes tend to indicate an "ears-preferences" for a certain degree of exponential bell loading within a horn. I'd keep that in mind if you're going to build more horns.

    - The horn entrance, back at the throat , can be made to be parabolic with some of the inner bell curve cut out to be "parallel". This gives an approximation of the H9500 or H5500 or even H9800 . Add 3 internal vanes and you're approaching some of the TAD hybrid horn designs .


    Also I'm currently using Waynes recomendation of 4 cu' for the 2235H instead of JBL's 5 cu' which I tried in the previous incarnation of this design and was very unhappy with. The 4cu' cabinets have much tighter sounding bass IMO.
    I've tended to migrate my own preferences towards smaller / "tighter" boxes. It certainly is a personal matter of taste.
    Too bad the current "status quo" in box sizes had you cutting unnecessary wood.

    Hey Earl
    The horn in the 4 Pi's that I built was the Eminence H290, a cool looking horn and compact but certainly not to my tastes. It might be better in wood but that's a lot of work to find out. The horn I ended up building wasn't anything special. Just a plain old 2345 JBL cast aluminum ( a real POS casting job if you ask me....lol ) that I had literally holding the garage door open on windy days. I had always wanted to build a wooden horn to try but never got around to it. I had some plans off the net but my not reading Japanese was holding me back. Anyway, after taking a closer look at the 2345 I realized that it would be pretty simple to replicate. The side are straight walled so that greatly simplified fabbing it up in wood (being lazy I didn't want to spend a ton of time on some that might end up sounding like dog stuff, and the alumium version certainly did sound like !@#$ ) I took a plaster cast of the profile and found that it too was constant across the curve. So without getting into a ton of detail (unless someone is interested) of how to build one I "whipped" pair together. As far as drivers I'm pretty happy with the 2470/2421 combo. The TAD look cool but I'm not sure I need all that top end extention. The next step would be to try a super tweet first ( eh Bo) . But all in all I'm just plain out amazed at how this wood horn has smoothed out the sound. CD's that were previously "unlistenable" ie R. L. Burnside "Come On In" certain comes to mind. Great CD, TERRIBLE recording job. I think they used one mike in a bathroom or something...lol .

    Waow Cool...
    THAT must be a loudspeaker with low low or almost no distorsion.
    Are you using some SUB1500 below also?

    Is that the AL1500 ?

    great, like the looks...

    can we have more pictures please !!

    Very clean design.

    Reminds me of a 3 way Altec I started out with and then the 3 way 2212H using the 2344 Robert Hamell is so rightfully proud of.

    Glad to see someone else has woken up to the advantages of the 3 way WMH. The mid cone at least to my ears mitigates all the so called horn/woofer colourations one all too often finds in the 500-1000 region, hell even a 2307/2308 can sound damn fine when the response is actually tweaked flat as. Its so much better and doable than a 2 way if you don't have assess to drivers like the 1500AL JBL Soa horns like the 9800 with a Be driver.

    If you can borrow a TAD driver I am sure the results will enlighten.

    Hey those are nice!!! How do you like the 2123?? Where are you crossing over??

    I agree my boxes are a little undersized, so to speak, although my 2235's are in 5cu.ft. Away from walls they are fine drop them into a corner and wow! Figure you will get some room gain but it seems a funny balance to end up reasonable flat, still have the power down low and still sound tight. I think the room gain is nice but I seems to not have the resolution, power, presence that full extension gives. But then it's hard to place them without loosing that sharp edge you seem to get set-up the other way??


    Can you show us how you did your horns?? Those look really nice and if they are kind of simple it would be a great thing to have up so others could try.
