In 2015, I purchased Clearwave Audio's 4CC kit to once and for all have a non-wimpy center channel speaker. This was about the 8th or 9th speaker I have built and was happy with the result. Though now it is not timbre matched to my main speakers which I have yet to remedy, but this made a huge sonic difference especially since this one speaker is bi-amped. In the image below, you can see that it was just about complete.  Having fun! ![]() |

Interesting. I am debating picking myself up a Klipsch RC-64, I have no will to take on another project and at least that seems like a substantial center. Plus it will timbre match my other front stage. Right now I am running a KLF-C7 with dual eight inch woofers and it does an adequate job.

The Centre channel is most certainly very important and it appears to be even more so with Atmos/DTSX according to my friends who have gone that route. I spent quite some time talking to my speaker supplier about which of his centre speakers matched the rest of my system. What he recommended fits in sonically without any real discernible difference with any panned audio that crosses the centre speaker.
Cheers
Gary

The center channel and subs make the biggest improvement in the Home theater experience! These are my last two centers, both Paradigms’   |

I know I'm setting myself up for criticism but I'm not sure the whole timber matched center principle is critical. A lot of soundtracks send such a huge percentage of audio to the center compared to L/R/surround so I base my center channel decisions on it's ability to reproduce vocals and other center track content and leave timber matching out of the process.
For fun, I will disconnect the L/R speakers and am often amazed how little is being sent to them during movies. In some titles, I would say as much as 70% of the total soundtrack is going to the center.
Sacrilege I know.

Equally important To having a good matchup to the mains (for center) is placement.
All of us deal in one way or another with that quandary of......
above or below the screen 📺
Screen too high or low, big, small etc. Having the tweets and midrange pan across left right and center (at the same height) is always my main objective.

Keith,
Tell us about the build- What do you like the best. (I like the drivers used)
Get some "Boom-Mat" spray-on cabinet deadener, really helps.
I'm will you folks, the center is the hardest speaker to sound good. I've rarely found commercial centers match the LR, so why not try something else.
I planned to use two Monitor Audio 6.5 gold, two 5.5 silver & a Gold tweeter for a DIY center. But I needed a nice pair of bookshelves for the partio, so used the two 6.5 & a matched pair of North D25-06 tweeters in a .5 cft cabinet. OMG, do they sound nice.

View AttachmentHaving fun! ![]() Nice build, I have built some of Curt Campbells designs that use the same mids and woofers, his had Fountek NeoCd3.0 ribbon for tweeters. I am currently running a set of his Anthology design and am very happy with them. I am sure that a few of his designs would sound nice with that center if you ever do another build. |

For texzick and anyone else that wants a little more information about this build... I struggled for a couple years to decide what center to use with my main speakers (Vandersteen 3a Signature's). The L/R and Center back surrounds are a combination of Vance Dickason's 5-channel system (Loudspeaker Design Cookbook) and a pair of Revel S206's (they were on sale) I used two MTM's from the Vance Dickason 5-channel system I built about a decade ago and they worked OK, but they struggled during louder sections of a movie and didn't have much bass. Jed Kunz of Clearwave audio makes some impressive speakers and his 4CC kit intruiged me since it was way less expensive than one of similar design from a major manufacturer. For under $1000, I could get all the components from www.speakerbuilder.com, the plans from Jed Kunz and move forward. Jed was very helpful as I asked a couple questions before taking the plunge. Having a bit of wood working experience with making some furniture for my house, building the enclosures was quite easy and I was able to get very tight tolerances. Not having any speaker design experience, I followed the dimensions per the plan, though others have made quite a few changes from the "plan" and had great success. The end result is quite good and the dynamics from this are much better than what I hear from many home theaters and in many stores. I no longer struggle hearing everything that the sound engineers wanted you to hear from a movie or music. I am quite concerned that I now have speakers from 4 different brands/designs in my home theater and will work on correcting that in the future. Clearwave has a companion 4T L/R design that I may do one year. But, to my older ears, I only notice it when doing some discerning listening. In the midst of a movie, the difference disappears. The midrange and high are quite smooth and do not make we want to run out of the room after a few hours. The mid-bass is there in spades as I have two 15" subs that handle everything below 80 hz. But, my Vandersteen 3A Signature's do sound better overall, as expected. I drive the system using a Rotel sourround processor and Adcom multi-chanel amps. The center gets two channels of 125 watts each, 1 channel for the woofers and 1 channel for the mid/tweeter. I am not thrilled with my veneering job and feel that I could do a better there, but I don't have much experience there since my furniture is made entirely out of hardwoods. I once made a 10" sub woofer and clad it with 1/4" hardwood pieces which came out beautifully. Thanks for reading.. Once again, I'm thrilled to find Emotiva and really enjoy the limited number of pieces I have. Great job, Emotive team! Keith |

Scott Scott, how do your JTR horn loaded puppies compare with your monster Legacy speakers? I would love to hear them both....and your thoughts! Tim Damn, missed responding to this one altogether. Sorry about that! The Legacy Whispers are a much more refined and accurate speaker while the JTRs are brute force but clean sound. I love the Whispers for movies as well but they don't kick out the volume of sound the JTRs do. Although I greatly enjoy live music through the JTRs. Something about the horns imaging that is incredible for live music and sounds just right for concerts. They are time aligned which helps a bunch but the imaging Jeff got out of these is nuts. Huge sound is the best way to describe them. You ever get anywhere near NE PA, I'd love to have you stop in for some toy time.  Scott |

That's a BADAZZ center channel for sure and would be in my theater if my Whispers were there. Scott |

Scott, what center did Jeff make you to go with your towers? He recommended the same speaker which was designed for center use. The 215 RM. It's a 215 RT but the bottom of the cabinet is cut off which makes it a more usable size. 4' long and 18" X 17" Scott |
