View Full Version : My bookshelf project



Moe Lester
11-07-2005, 12:25 AM
Well my birthday is this sunday and I decided that I wanted some speakers and other items to build myself a pair of bookshelf speakers. Its going to be a simple 2-way setup using a 6" midrange/woofer and a 1" textile dome tweeter. I am building a passive crossover with a crossover point around 2.3khz.

Midrange/Woofer: http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=297-444

Tweeters: http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=277-408

I cant thank Lemans enough for the crossover design and help with driver selection :) He really is a helpful guy.

Final Order:

As soon as these items come in I will take a few pictures. I plan on starting the enclosures tomorrow. I am going to try .5 tuned to 40.

pics will be coming today of the box building. i havent started. I really dont know that much yet. This is my first true HT project. Building enclosures is what I know how to do, but designing crossovers is beyond me lol.

Well der, that's why by tweaking I was referring to replacing parts to lower/raise the x-over freq.

I did them with my tablesaw. I used an 80 tooth dewalt blade. I want to get a new one because my dewalt is getting dull but out of a $30 blade i couldnt reall expect much more. The slower you cut the smoother it will come out :)

Ports are in place. I decided to go with 45hz instead of 40. This allowed me to make them not quite as deep as they would have needed to be. Flaring the PVC on the router was quite scary as well since there was barely any of the PVC sitting on the router base lol.

Well I cant really go any further. I need a 1/4" straight router bit but I have no clue where mine went. The ports are permanently attached now. Tomorrow I may get a new bit so I can get a little more done on them.

Looks great bro, congrats. Just got a few questions....how do you flare the pvc for the port? Why not just use a slot port? Cant wait to hear how these perform, looking for ideas for my own bookshelfs.

Moe Lester
11-07-2005, 08:32 PM
I did the flaring with a router and a 1/2" roundover but the cutting edge was sunk down only around 1/4" The pipe was barely on the router base so it was a little rough so i hit it up with some 60 grit paper and that knocked down any lumps quickly. Then 150 smoothed it out nicely.

heres closer shot of the port flare since it seems to be a small topic of its own right now and you can see its now permanently attached to the box.

I havent flared the back yet because i am not sure how I am going to finish these. It will however get the full 1/2" roundover :)

Moe Lester
11-08-2005, 06:17 PM
If anyone has the woofer and or tweeter i was wondering if you could do some measuring for me. I need the depth of the tweeters mounting flange and the overall diameter of the hi vi d6.8 mid/woofer. I want to get the cutouts for the speakers done but until I have those measurements I am stuck.

InhumanAcura
11-08-2005, 06:24 PM
woofer...in mm

http://www.madisound.com/pdf/hivi/d6.8.pdf

the peerless data sheet doesnt have any measurments..

http://www.madisound.com/pdf/peerless/811815.pdf

Moe Lester
11-08-2005, 06:33 PM
is the 158mm the diameter of the center of the screw holes and the 174mm the overall speaker diameter? its a 6" mid so if its 6.75" across id assume theyd call it a 6.5???

Lemans used to or still has this speaker so im waiting on him to clarify the cutout sizes.

InhumanAcura
11-08-2005, 06:35 PM
i believe the .8 is the designating the nominal impedance <-idk where that came from out of what you asked..but, yeah it does look like a oversized basket though..got more mounting holes than an mt

looks like 136 for cut-out and 158mm for the over-all basket diameter

yeah i know that is for the impendence. I dont know what that 174mm measurement is though. If it turns out that the speaker is 174mm diameter then itd be ~6.75 overall, if its 158, then its ~6.25 overall.

11-08-2005, 06:54 PM
just a little tip, when you make the crossover, PLEASE dont just start soldering everything together. get some breadboards, and put the components of the crossover through the back, and then wire it all up :p:

i just hate seeing ugly components :)

oh yea, let me know how they sound, i might make some of these soon... dont forget to add the box plans and whatnot

Moe Lester
11-08-2005, 07:00 PM
box plan:

Top & Bottom: 9.5" x 8"
Front & Back: 9.5" x 14"
Sides: 14" x 9.5"

2" PVC 7.25" long The PVC's OD that I have is 2.375".

http://img413.imageshack.us/img413/5548/plan7et.th.jpg (http://img413.imageshack.us/my.php?image=plan7et.jpg)

After the drivers and crossovers go in, it should end up somewhere around 0.5 cubic feet tuned to 44hz.

dont worry req, i was planning on laying it all out before i soldered anything. I too hate ugly parts :)

cutout is 5 3/8"

i got the cutout, but i need the overall diameter so i can flush it in.

edit: nvm, overall diameter is 174mm, 6 7/8"

Moe Lester
11-09-2005, 01:28 PM
Here are the last pictures until I get in the speakers. I need the depth of the tweeter before I can do any more cutting. I ended up buying a few bits at harbor freight and they cut suprisingly well. I dont know how long they will last but whatever, they got the job done.

3/8" roundover behind mid/woofs

http://img68.imageshack.us/img68/6104/cutouts11gy.th.jpg (http://img68.imageshack.us/my.php?image=cutouts11gy.jpg)

Flush cutouts for the speakers, 6 7/8" OD - 7/32" Deep, 5 3/8" ID

http://img79.imageshack.us/img79/2706/cutouts22le.th.jpg (http://img79.imageshack.us/my.php?image=cutouts22le.jpg)

At first I wanted to center the mid on the front and have the port under it and the tweeter on top. There simply wasnt enough room to do so. I did not want the speakers and port staggered so I opted for the port firing out the back. I think they will look alot better this way.

Anything not on the list is being bought by me. The enclosures were scrap MDF I keep sitting around. Free... Brad nails and glue i buy by the 5000 and gallon. Basically the enclosures are costing me nothing, the most expensive part of the enclosure will be the **** laminate lol. Gotta love grandparents though :)

dont buy power tools from harbor freight, i have a power sander and a sawzall from there, both are total pieces of ****.

you can buy almost anything else there, and just expect low quality.. but it wont matter as much as much on hand tools as it would on power tools.

i bought a compressor there thoughat the same time, and that thing works great, paint gun is okay... but i've never owned any other paint gun, so i dont really have anything to compare to.
