@epa: Do you have a plan for your design?
"it was something like 60 wide*90 high*70 deep cm "
I have birch ply cut up for 2 boxes with these dimensions, might as well use it!

Hi guys and gals

I finally pulled the trigger and started building 2 THAM15's after reading such good comments on them both here and on other forums.

Here are some pics from the build:

This is the phase where I am now

Hello, This is my first post and my first attempt at Hornresponse. Although I cannot figure out how to capture the spl plot, I am seeing a very similar plot to the 15TBX100 when modeling the Celestion FTR15 4080HDX in the Tham15. Can anyone confirm or deny my findings? (realizing this is a dead thread and hearing crickets chirping) Thanks

And finally the first test outdoors together with our EAW KF300e tops

We were running the subs from a bridged Crown XTI4000, limited to 100V, ie about 2600W for the pair and when going full out we could watch the pebbles on the ground dancing :-)
The sound was very tight and clean, and if You stand in front of them and try to talk Your voice will be modulated, feels quite interesting. We did not do any measurements other than using ears and stomach but the consensus was that they really deliver in the range a rockband needs, ie the bassguitar fundamentals are stunning, the kickdrum in the 80 Hz-range is really kicking and they can go up into 100-150 Hz if needed.

We have now gigged with this setup the whole summer and the expectations were fully met.
The deliver that tight, clean sound that we want, the dB/m3 is exceptional, the handling worked out perfect with the wheels and handles and we are just happy with the build.

No, I used the B&C 15PS100. The driver recommended by Martinsson is the B&C 15TX100 but after lots of simulations and a long look at the pricetab I decided to use the cheaper PS-model since the only real differences are (in this order) price (cheaper), power handling (a little less but still 1 kW) and a little less group delay.

nice job on the subs.
seems a solid bild with a nice finish
also like the placings of the handles ,and speakons.
only thing i dont like is the mesh grill.
why not use stretch metal?
