You can also find the several reviews and variations on this design on several forums...including good comments from really good speaker designers, and also for the Dayton Audio TCP115-4 4” woofer that is used on this 2 way speaker known by the bass it can produce.


The reasons to choose this design where easy:

*A small 2 way with flat response, details and clarity. There is plenty of images with the frequency response and such.
*Components where cheap…i´m in south america so shipping cost are also take in account.
*Few components crossover… i read/think too much about the changes that every electrical component/equipment adds to the sound, this is a series crossover, only 4 parts.
*Small size and Area to be fulfilled… Just a small living room.
*Good reviews for design and components… from designers on other forums and the drivers itself on youtube.
*They are been made as a gift for my Dad (73)…so he doesn't need to get a Beryllium tweeter either way (Even when he deserve it..i cannot afford it)
*Also for my to compare it with a full range MarkAudio speaker that i build on planet10 mFonken enclosure that i REALLY like as was my first diy speaker and i'm still impress on how a good FR driver with no crossover whatsoever sounds that good.

DRIVERS:
Woofer Dayton Audio TCP115-4 4”
Tweeter Dayton Audio ND16FA-6 5/8”

CROSSOVER:
3 OHM 10W RESISTOR
0.20mH 18 AWG COIL
8.0uF CAPACITOR
1.0uF CAPACITOR

ENCLOSURE

I do changes in the cabinet outside dimensions, trying to apply the theory on Direct Radiator Loudspeaker Enclosures by Olson Harry.. also to impress my Dad on what carpentry with cnc can do now days.. the internal dimension where the same that other builder used on Mr Duane design and call it the ¨Deluxe version¨ as he made it a litter bigger and change the crossover components to polypropylene versions on the capacitors. The original enclosure is 8” tall, 6”wide, and 8.5” deep.
The enclosure material is 18mm pine plywood, lining the internal walls with recycled denim, the material used on car trunks/carpets.

I think i don't have anything more to cover so here some pictures of the build process

FLAT PACK..To call it in that way

The letters on the top are my dad´s name initial..in case you are wondering



Baffle -- recess cut for driver to be flush mount and release on back to let it flow

Binding post cut manually done, as the cnc guy ¨forgot¨ to do it...not finished in this photo

Glued together - I'm missing a photo with the internal material--next time i post

Crossover assembly - testing - finished

and the Ufoken enclosure with Markaudio CHR-70.3 that i did as my first diy speaker that i want to compare against this 2way design

I will post more picture as i progress with the process.. hope this week is going to be complete already.
And by the way English is not my native/first lenguage in case it wasn't noticed.

Very nice!!

Looking forward to your sounding impressions!!

Also, just to ask... it seems that you modified the baffle's width... that supposedly change the BSC or not?

I will update this post, there are already complete. Still on the break in process but the sound amazing. I can feel the bass boom at least on a small room, and they also disappear from the sound on some tracks..on others I can hear the separation of the sound coming from the tweeter or woofer not sure about that, it could also be that the recording is made on that way or that it sound with much transparency that the one i use to hear.
I leave the baffle as the original ¨deluxe¨ design sizes, they look more wide because of the flares to name it in that way that i add to the sides, and the shape i use.. but all the dimensions are the same.

installing the croosover inside



port fix test


the sides of the speaker already assambled


as you can see, the width of the front baffle just insert on the sides panels, that goes on that angle to the back



and then the finish speaker on the left thats the one with the mineral oil alredy applied
