Haha ... you "perfectionist" Noticed you turned the grille 90 degrees

Awesome SIR Show us the pic when done. (Almost) decided to put my 12" Yammie in a cabinet identical to Heresy I's ... getting a pair of HI's this Wednesday, so why not Cheers, Emile

Just emailed him to see if "in stock."

Did not email him ... he's "out" of stock on these?

Hi All, Quick question ... picking up a pair Of Heresy I's this coming Wednesday and one has a blown (?) K-77 tweeter. So; will replace the diaphragms (in both). Yes; know to stay away from the aftermarket Chinese crap Normally would buy them from Bob Crites ... but SimplySpeakers.com is 5 miles away from me and of course I want to fix them "now." Their diaphragm https://www.simplyspeakers.com/klipsch-replacement-speaker-diaphragm-k77-89486a-2.html has been used/reviewed by @CECAA850, @moray james(I think) with results as "good." But believe @jason str labeled them as garbage Should I just (wait a couple of days) and get the Crites' ones or are the diaphragms from SimplySpeakers the same? Many Thanks, Emile

@rjp ... SHOWOFF! Just kidding; amazing wiring job ... much cleaner than mine

For what it's worth Was planning on getting some Heresy's for my fronts (via AVR) ... of course have been waiting for 2 weeks on the (local) seller But; plugged the T/S parameters in the online calculator and the "recommended" volume is pretty close to the actual box Not like my Yammie contraption

WOW ... my box is getting smaller and smaller

Tom; thanks! ... sorry; typo (I think ). Tried mh-audio.nl , diyaudioandvideo.com calculator and a couple of others. Downloading WinISD now. Do you know of any place where I can "hear" the difference. Can "see" it from the graph below (from http://audiojudgement.com/sealed-enclosure-closed-box/ ). If I "feed" my center speaker only freqs > 100Hz, it doesn't seem to make much of a difference if I use Qtc=.7 or 0.8 or even 0.9. (But a GREAT differenc in box "size") But then ... maybe I'm crazy Cheers, Emile Add-on ... bought this speaker primarily for the large horn ... also want to get a good mid-range out of it ... say >200Hz ... not concerned about low bass ... have KPT-904's and a 15" sub for that ... ????????

OK; after searching and learning, it seems that Qtc is the parameter that REALLY impacts size/volume. Generally recommended is a Qtc of ).707. If I go to Qtc=0.8 my box will be about 30% smaller ... Qtc=0.9 and it is 50% smaller. How concerned should I be about Qts [edit] mean Qtc - especially since this is a CENTER speaker and I really don't care about bass less than say 100Hz. Thanks, Emile

@JohnA ... looks like my KPT-904 ... HaHa; my wife would kill me even though the sound would be superior

Yes; bass sounds tight and musical ... just no clue why this would be in a 2.0 cuft ported cabinet as all indications lead to a 2.5-3.5 cuft sealed box. ???? Thanks, Emile add-on ... read somewhere that the manufacturers often design the smallest box possible ... the size being on "the edge" of loosing quality ...

plagiarized from soundonsound.com ... Quote Most stereo systems have two main speakers, yet we have only one subwoofer. Why not two subwoofers as well? In some situations there can be advantages to having two (or more) subwoofers, but in general one is usually sufficient. The reason for this is connected to the fact that, for frequencies below about 700Hz, our sense of hearing measures the phase difference between a sound arriving at each ear, whereas above this frequency it uses mainly level differences. Out of doors, our ability to determine a sound's direction remains quite accurate down to remarkably low frequencies, but this ability collapses when listening indoors. Sources generating low-frequency sounds (below about 100Hz) tend to do so more or less omnidirectionally (the sound wave travels from the source in all directions) because the wavelength of sound is usually larger than the object itself. When a low-frequency sound is generated within an enclosed space, the spherical sound waves created will reflect off the boundary surfaces of the room to arrive back at the ears with a multiplicity of phase variances, due to path-length differences. This confusion of signals makes it impossible for the ear and brain to extract a reliable phase difference, so normal directional acuity fails. So in theory, since you can't tell where the low frequencies are coming from in a room, one subwoofer will be entirely sufficient. Unquote

@karlson3 ; many many thanks!

Yes; the "holy grail." But there is NO way my wife would ever allow those in our house

WOW ... Klpisch ! True collector item

You lucky guy How come I don't get these benefits Sold my pristine KG4's on CraigsList ... guy came and loved all my speakers ... so; I gave him an additional Dynaco SS amp and a CD player ... all for $200. Then he had the guts to call back to ask me if I had found the original diaphragms so he could pick those up also (for "nothing"). Told him they were $50 now ... never heard from him again

JEEZ ... beautiful. But just get both

escapades? Don't tell my wife Yeah ... Lightning ... Hate anything "Washington, DC." Hold out your hand and get money

Haha ... the "upgrading" never stops. Got Forte's in my stereo room and really like them. Cornwall's in the TV room ... now used as rear speakers since I got some KPT-904's. IMHO, try Klipsch Professional speakers and you will never have to "upgrade" again Cheers, Emile

Trying to "transplant" a 12" woofer, 14x8" horn (w/ 2" diaphragm) and crossover from a (oops; blasphemy ) Yamaha stage monitor into a WAF friendly box. Planning on a sealed box to keep the size to a minimum - and not concerned about "low bass" since it will be a center speaker Calculated the required volume from the T/S parameters and it's about 2.5 cuft. (Actually does not make sense since the original PORTED monitor only has a 2.0 cuft volume ) But; seems "stuffing" is required, especially since I''d like to make the box smaller Lots of reviews on polyfill, fiberglass, denim insulation and others. Of course there is NO consensus, except that fiberglass seems to be "one of the best" but of course a pain in the azz - OK; hands/arms. And ... polyfill is overrated Any suggestions or comments? Much appreciated. Cheers, Emile

Speaker cabinet volume calculations are a complete waste of time! OK; trying to see if I would get some comments on this Got the T/S parameters for my driver - see original post in this thread. Used several online calculators and the results averaged to about 2.5 cuft. Manufacturer (Eminence) recommends 0.9-1.3 cuft. Haha And even funnier ... have this speaker in the original PORTED stage monitor box with internal volume of about 2.0 cuft. Note; since it is PORTED it should translate roughly to a "closed" 1.0 cuft box. Guess I'll just buy some wood, and start cutting without measuring anything Cheers, Emile

add-on ... The APC H10 (or newer black version H10BLK) "officially" is a power "conditioner." Yes; recommended. Cheers, Emile

I am using an APC H10 ... don't even know if it qualifies as a power "conditioner," but think it was a good (and fairly cheap) investment. Living in Florida, we often have "lightning" outages. Unit has worked well as protection for those. Also, the other day, it completely "cut out" several times as the line voltage dropped to "too low" voltage levels. Cheers, Emile
