The APT80 can bee seen from behind. Its the same Emenice tweeter used by many, but with a less developed horn... simple half circle.
As this Heresy is really for near field listening a better horn seemed un-needed. Instalation was easy... 2 1/4" hole if I remeber right... cut from behind.
The APT80 is $25 with horn... not bad at all.

Here is a pic of the 2nd piece used... have 2 interlocking/different depth pieces creats more sealing serface... This thing is rock solid... weight nearly 80lbs each. Though Small... might be my fav speak thus far.

I bought a set of Heresys for my office, but they were very rough... thus new cabs. I took liberty to add somw volume to the cabs... many said this was ill advised so I cut some extra MDF panels to reduce the internal valume back to ~1.9cu ft. The cabis noew 2.25 thick on the sides and 1.5 everywhere else.
God Bless Home Depot. and the free cuts :-). Not having a work shape a little extra time there allowed me to build these without a saw.
K700 metal horn, K55, APT80 tweeter, Bobs 12" LF driver and crossoevers.
The Origonal Heresys have made there way to my office.. So rough I cant see them growing legs and leaving.
These DIY Heresys had no home... were in my closet for a mo or so... My in-laws saw the Speakers and an old tuner... now they have a retro system on loan. Im told Im not getting them back, but... they are sadly mistaken. Just no room now.

I got these bins on a horse trade gone wrong... VERY ruff shape. I took them to my cabinet builder and got some help. I wont show the before pics... but work included: removal of trim that was not flush, routing edges to be flush, laminating 1/2 baltic birch, Adding a keyed bottom plate and resealing everything. I was having some cabinet doors refinished down the street from where I work... really nice guy.... so the Bass bins got a Walnut finish. Top cabs are almost done... Will be mounting the horns from the back and using nuts. the barrier ship to conect to the LF driver will be accessed via a hole cut into the bottom of the Horn asmbly. Finally I have a nice set of splits.
Bobs cross overs, and tweeter, K400 horn, K55 driver, Bob's LF driver. The bass seems tighter/faster then my Cornscala in the background... Not sure which I like more.

I have a K55 that has a bolt style look the one shown.
I had bob replace the diaphram... he saw no diff... checked perfectly.

Youre right APT80. I used the APT80s on a Heresy Clones I made (The origonals are in the office).
I could not tell the difference between the 80s and the 150s So the 150 went back.
It has been sugested that the horn/lens on the 150 is too large and will dominate the sound... was not my exp. but I could see this rational. The APT-80s install easier in my opion. Just drill a 2 1/4" hole.... dont remember the exact size, but shoudl be close. For $25 a piece I intend to buy 2 more just to hold. I now have 3 pairs in use.
-
The APT 150 had be bought new from http://www.speakerrepair.com/
I might try the APT50, smaller lens, same driver.

One of the things I love about them, was based on a serious error. I built the caps @ 2.2cu ft. On many persons advice I brought the vol down to 1.93cu ft...
I used MDF, gorilla gue and decking crews... The added weight makes a real pain to move... nearly 70lbs each... but the bass is unuasally tight and fast.
The way I built the cabs is a box covered with a box design... creating 2 faces to seal... thing cab seals up air tight!
Worth adding batting? Will include better pics in a bit.

Compairing these Heresys to my cornscla's (PH800 horn) they seem a bit sqwaky... but over a really nice speaker.

Ok... Its official... It is cheaper to have left alone. I bought beat-up original Heresys, but didn’t like the cabs... Now I’ve built my own and my beat up Heresys in my office at the parole office. These are 100% new... parts sourced from Bob or ebay. The cabs had to have a lot of material added to get it to 1.93cu ft. The sides and back are at least double thick. Sides are 2.25in, the back is 1.5". The bass is so tight now... no cabinet talk. These are at home... I think they’ll be a gift for the in-laws. On a side note: I traded my 1 commercial La Scala, for a set of base bins... Bought 2 used k400 horns, and I got to tell you... The K400 is massive. The rest will have to wait till after the wedding.

Origonal Heresy Parts... Well the K700 and K55. Bobs tweeter.
Im half thinking of building these new and bringing the guuuuulllly heresys to my office instead.
-
Im just trying to get these Heresys sorta back to basics... went overbaord on the new cabs.
I did call Klipsch today and found out I can buy a K401 for $50.... WOOWOOWOWOOWOW amaging. After my weding May 1 I will be buying just to hold on to :-). G/F is a bit unhappy with the number of large speakers... let alone tube amps. :-)

OK to drop the volume down, I have cut a back panel .75thick (20 15/16 x 13 15/16) and top and bottom panels .5 thick (13 15/16 x 12 3/16)
So new internal measurements are 20x14x12.25 = 3430cu = ~198cu ft.... Im done... Good I hoep it sounds good.
I bought garilla glue and 1 5/8ths deck screws... the inside of this cab is wayyyy tooo thick... I love heavy but wow...
Side are 3/4" mdf + 3/4" oak ply.
Front is 3/4 Oak ply, read is 3/4 oak ply + 3/4 MDF.
Top and bottom are 3/4" oak 3/4" MDF + 3/4" MDF The top and bottom have 3/4" MDF+3/4 oak, glued and screwed. I now have to glue and Screw the additional 3/4 MDF to the 3/4" MDF.
I soooo hoope no resonant sounds happen.

I remesured things... I was working in the ER... hard to concentrate.
Internal measurement is 21 tall x 14wide x 13deep
21x14x13=3822cu in = ~2.21 cu ft Is .2 over too much?
If I have to bring down. I can add a 3/4" mdf panel to the rear... making is 1.5" thick on all side but the motor board.
21x14x.75"thick=220cu in
3822cu in minus 220cu in = 3602cu in = ~2.08cu ft Seems very very close then :-).
21x13x12.25 = 3601.5 ~ 3602 = ~2.08
Heresy I specs: Outside 21.4" (54.36cm) x 15.5" (39.37cm) x 13.2" (33.53cm)~ Inside 20” x 14 x 11.5 =3220 cu in - ~ 1.8cu ft
From what Ive read… many feel the cab could func. Well as a 2.0 cu ft cab.
At 2.2cu ft (as is now) is .6 larger than stock.If I reduce to 2.08cu ft is .22 larger than stock
Thoughts?
Thank you

I bought 2 Heresy speakers... the Cabs were rocked and had my cabinet maker make a set of newones to drop my parts into.
I got the wise idea of using slightly larger measurements (Internal) 21"tall x 15" Wide x 14" deep. ~2.5cu ft instead of ~1.8cu feet.
Is this going to mess things up? I can add material to 2 sides... Its 3/4"mdf + 3'4"oak ply on the sides, top and bottom and only 3/4" oak on front and back.
So I can add alot of matterial if needed... Do I need to? This are stock, using the old parts.
Thanx, Justin

Industrial Heresy Ports
I have 2 used Heresy II Im updating.
K700 with K55, Bob CT125 Tweeter, and stock 12” driver.
I have these 2 cabs, I want to know the merits of adding 2 ports just like the Industrial Heresy.
What size were these ports, how deep?
What are the benefits of this? Allows the Heresy to deep down further… Gain of an octive?
Thank you, you in advance.
