SynTripP: 2-way 2-part Virtual Single Point Source Horn

Would you mind posting the final sim parameters from hornresp? I can also take the cross sectional areas from S1...S4 with L12..L34 and use that as a guide if that is easier for you.

I feel like I am asking a lot from you, and I don't want to inundate you with questions. I am sure you feel that you have spent too many hours on this already!

Let me know about the hornresp parameters. I see some old ones from the Synergy Tripp 10 thread, but not sure if they are final.

Thanks a million, Art!

The Hornresp parameters in the Tripp 10 thread are probably as "final" as they ever were.

The actual measured response was similar to the simulations, but the arrangement of the bass reflex ports can't be exactly modeled in Hornresp, the length and size of the ports had to be worked out empirically to achieve the desired Fb of 81 Hz.
 
Recreating quite nicely

From 1.4 square centimeters to 1399 square centimeters with 33.5cm length

Using Post 41: 9" horn exit height (including grill cleats) as a constraint

Made good progress in the shop today

I decided to make router jigs for the inner horn pieces (the jigs include the longest miter dimension, so I can trim the miter off using the overhead fence on the table saw tomorrow).

I am using Fin's sketchup model mainly, and his plans as a guide/doublecheck.

I have the inner horn pieces cut, going to do the miters tomorrow and see how it fits before cutting more for the second horn

Hopefully my roommates don't mind being in one of the photos, they are building a new kitchen counter!

Still have to do the 1/4 round around the bass reflex ports that Art calls for

That horn is coming along very nice. Great job taking your time an getting it fit together. Your results are way better than the horn I built.

Keeping an eye on your progress. I love my SH-60 clone. I am working on finishing a passive crossover for it soon, they are so much fun to listen to.
 
Whoa that is one heck of a compliment, thanks xrk!!

I'll tell you about my process in more detail if ya want tomorrow (or later today by now I guess) I just got done cleaning up and getting settled into bed- finally. Was having a really great time!

No CNC here yet (I hope someday soon). Using table saw, track saw, band saw, drill press, jig saw, files, and router. Improvised some good tricks with the router that really made the difference, I think. Man I love that thing!!

The tools... we have been slowly acquiring them over the past two years, collectively. At some point things got real, and it was time to start a builder space. Things are just getting into gear here (just moved in middle of Jan and pretty much done with build-out). It's been 0-100 since the beginning. All 12 of us here are makers, artists, builders, friends, living together for 3-5 years already. Pretty much family to me!

Okay must go to bed.. Thanks again for the kind words :) More on process tomorrow, sleep I must.
 
Miters are coming out great!

Overhead fence on the table saw is killing it!

Took some photos to show it

Miters are done, dry fit is flush

Made a router jig for driver relief channels and routed the sides

CHEERS to Fin who has been a HUGE help! Could not have gone this well so far without him. THANK YOU Fin!!

Xrq, you have to invest in water cutting for foam.... the skill level is becomming huge here !:D

Btw xrq, Weltersys : what about foam flat pack to glue with just a little heavier damped wood throat ?

Weight & shipment abroad should be easier : so cost as well ? (I mean for the one with no cut skill ;) )
