Epique Bookshelf speakers // Build plans 

People are way too overly dramatic about wood movement.

@@earthtoandy_ You are so correct. I am still amazed at how my Solid hickory $8,000 kitchen cabinets with the Sink and dishwasher, the stove All that Heat and steam, Oh and all at moisture and they are still holding together. how in the hell could that little 8-inch piece of wood ever last in a dry room with stable room temps is beyond me.

I will now forever refer to my sander as an iron to get the wrinkles out of my wood.

do it with cheapter alternatives like tangband w5 and stuff

I'm building a mini tower with two matching passive radiators right now.

@@Erikdidit Do you mean two per 1 sub per speaker?

@@potsy9973 yes

I agree on both fronts. I was trying to find out who the artists were on the vid. I am getting into diy hifi and both tracks would sound sweet through my system. Anyone know?

The music is from epidemic sounds.com

Bass extension per Dayton spec is 30hz. It's only a 5 1/4 inch speaker with a large surround and good X max.

30-4000hz for the 5.5" , 25-3000 hz for the 7" version

I'm wondering the same thing! Apparently Epique claims that their speakers can be both a full fledged subwoofer and mid woofer at the same time due to a special design with the driver. Not sure how true that is but they sure do look awesome

That fat surround must cause some nasty diffraction

I purchased a pair of 5.5" Epiques to test, and while they go deep, the mid-range suffers. I have two pair of 2-ways using old (NLA-US) 6.5" Peerless NOMEX mid-woofers that go down to 40Hz (by design and my choice) but up to 6000 Hz, limited by design to about 4000 Hz and crossed to the Peerless tweeter at 3.5 KHz. I have a 12" sub woofer for music (more than enough with 500 watts) in my tiny 13.5'x 15.75' (9 foot ceilings) living room. I listen to quadraphonic 15 IPS tapes and 4 channel LP's almost daily. Yes, my LP's are over 37 years-old, but being they have always been played with a quad cartridge on good to for 35 years, outstanding turntables since (I have four for LP's and one for "78's") and my 1975 TEAC tape deck has new heads, both the tapes and LP's should sound as new 100 years from NOW. You might accept the 5.5" Epique's mids, but I wasn't happy with any XO topology to currently available tweeters. The measurement graphs showed what I heard. Maybe there's a tweeter made that would sound great with the Epiques, but I haven't found it. Very frustrating.

When you make yours, you should do exactly that

I'd personally go with an actual 18 inch subwoofer for the low end at that point for massively increased efficiency at the cost of real estate.

Epique is a sub , not fulll range dummy

its a sub dummy, not a full range

Yeah, I think I do. I will look it up for you. But you will need another crossover design as well. Maybe you can send me a message on erikdidit.com?

Every answer is included in my buldplans that I sell

@@Erikdidit at least answer me this please, I will buy the plans btw, but did you use winisd to model the port dimensions ? Every time I go into winisd I get crazy large port dimensions. And when I see these super short ports I wonder how its even possible (I'm a complete beginner but I'm really into the hobby of building custom speakers), as far I know, to prevent chuffing you have to keep the wind velocity below 16m/s but any attempt I make at doing this by increasing the size of the port I get these crazy long ports. How are you keeping it so short, does it have to do with the internal volume of the speaker, as of this moment I have only modelled using smaller enclosures

@@hermangaviria690 you are probably trying to tune the port too low. It is a balancing act between a few different factors.

​@Erikdidit when I don't tune the port low enough I get a huge bump on the low end bringing it to a chevichev response. I specially have a hard time believing how chuffin isn't an issue with this build. I'm a huge beginner so I do apologize for the trouble.

Yes, is has two coils. Wired in series. I think it is easiest for you to Google it. In from amp to positive on either terminal, from the negative on the same terminal to the positive on the other terminal and out to amp from negative.

@@Erikdidit thanks, just spotted that in the video

I think tiny subwoofers give you better midrange clarity than big subwoofers

Subwoofers were never meant to play midrange in the first place.

Have a look at the VoiceCoil Magazine test. The drivers have a bit of unevenness but very good extension through the midrange. No reason these won't perform well. Obviously less efficient with the heavy cone but the motor is huge and can easily control this driver, just plan to have a beefy amp for SPL. That slight unevenness due to the large surround is is a very solid trade off for the bass response. Really though a Passive radiator could be used here.

I absolutely believe that midrange is great...I just wonder about doppler distortion. Thoughts?

@@aaronmatuszny8856 Good point, I forgot about doppler distortion. In that regard, the smaller the subwoofer, the longer the amplitude which means bigger doppler distortion

I use epidemicsound.com

Hi, I used to enjoy Kirby's videos as well, he inspired me to start my channel. I can't say I know anything about him tho. If i remember correctly I think he had a kid about the same time as he stoped uploading videos. For me it has been hard to have time and energy to make videos since we had kids.

@@Erikdidit Well its a tough world i guess. But i can say is the passion to make something and get it working is totally a great feeling all together . But anyways great build with these one . Absolutely loved it.

Yeah, you are right. I have changed it to polyester damping. When I held a piece in my hand and tried to blow air though it with an air compressor I noticed that it doesn't circulate air.

Erikdidit.com

Yes, it does :)

cool! looking forward @@Erikdidit

Spring gang - you left behind

You can use pretty much any amplifier you want. However, at 64watts the woofers will play 89db at a listening distance of 4m (13feet).

@@Erikdidit but won't this cause clipping ? I was under the impression you always had to use an amp that had the same rms of the speakers or more. Do you just keep the volume down? Did you wire them at a 2ohm or 8ohm load ?

A little sound demo would be great.

I'm not a subscriber yet. I was having a software glitch, trying to upload. I was just going to ask if you had already ran numbers for the 7" epique w PR, ( one of each per speaker). @@Erikdidit. I got all my panels cut today, but not to exact lengths. I still have to establish a parimetre value. I'm going to keep this one basic and see how it goes. If a particular 6.5" mid bass will work I might try a 3-way with separate boundaries. Oh and of course sealed.

They only make this 5.5" and a 7".

@@analogkid4557 thanks

@@armandomorenoromero8531 BTW, you can order them from Parts Express.

It's not a subwoofer. It goes out to 3k very flat.

@@analogkid4557 @78 dB sensitivity!!! It is a subwoofer in that regard... Add an passive crossover and the sensitivity drops to 74 dB @ 3K Perhaps a good option for an active full DSP speaker.

@@wellroundedsound2422 not really. They pretty much have bsc built in. They are rated at 83 db. With the power handling and excursion they will hit 107 db. Personally I would use two per side.

I measured the speakers in their cabinets to get accurate values for the crossover design.

The deep on about 6khz? its really parallel measurements? @@Erikdidit

Not officially

Do you work for Mills and Sonic Cap? Nothing Epic about getting swindled by buying expensive caps. Anyway the woofer has a Klippel verified 14mm linear Xmax, so yah it is beefy and can move as much air as a typically beefy 8".

@@gregorymorrill7558 use your ears more and eyes less maybe you would like to tell Danny from GR Research that but i suggest you maybe watch and learn what a real x over is first and realize either of us work for anyone but our selves and our ears not eyes and you should too by trying them which you have not properly done either!!! but hey just trying to help you and your sound out if 6$ is killing your pocket book for a cap my bad!Again no sales pitch just facts Jack!

@@rexxx927 Danny at GR is selling(shilling) those expensive caps to make money. He has his views which are typically not shared by others who are not making money off those products. You decide.

@@gregorymorrill7558 wild thing is I or danny have 0 interest in them other then sound i guess your gonna tell me your sandcast resistors are superior too???? sorry i bothered with a suggestion for you please excuse me

@@gregorymorrill7558 Isn't every company selling audio related speakers and components trying to make money? Last I checked that is how a successful business functions! Simply trying better components in the crossover can make quite a difference, I speak directly from experience. Remove anything magnetic and use good quality parts, that don't have to break the bank either. But if you are just going to pick sides and argue about stuff, you probably don't really care about great sound anyway! I'll bet Danny's system is better than any of ours!

Yeah, unfortunately. I will make an alternative version

@@Erikdidit Yeah sorry mate! On a positive side - more to explore. 😀If I might suggest try some SB Acoustics tweeters. Amazing performance across the board.

I'm not showing the final crossover in the video since I sell buildplans.

Just cross them over around 2500 hz just above the low end of the tweeters, most tweeters only go down to 2khz buy some cheap coils and caps & once you got it buy good ones, you only need 1 coil & 1 cap add an lpad if the tweeter is too loud, don't waste your time and money on 2nd and 3rd order xovers, don't use resistors
