Hello all folks across the pond ;), I have decided to go down the DIY route myself.

Big thanks to the other HTM-12 owners on this forum who have inspired me and posted very informative and helpful build threads!

This will be a slow progress build and will take time no doubt, however I will definitely be posting pics and updating this thread as and when things are moving along.

I have placed my order in just now for 3 x kits of the HTM-12 and the pre assembled crossovers which has cost me $970 or £750 and will get my MDF for the cabinet build cut tomorrow or in a couple of days when I am off work... I've also just ordered some more clamps from Amazon so will await for all to arrive before I commence.

Will hopefully update with some pics during next week
:)

congrats from me too . .

which glue will you be using and will you be using a brad nailer?

using mdf you'll want to stabilize the panels for straight and square while the glue sets up

waiting to see the pics . .

Thank you @asarose247 I don't think I will be using brad nails as I don't have a brad nail gun.. I was looking to get the Ryobi Air Strike for this project but others have advised just to glue and clamp as the glue I am using "Gorilla" is more than sufficient for the task. I did a test with the glue on some scrap mdf and it was super strong. When I tried to seperate the two pieces I couldn't I forced it and it ripped the mdf off but the joint was still intact :) so I think the glue will be the way to go for me with plenty of clamps and a band clamp too.

I used glue and clamps on one build.Works fine doing it that way.

On another,I bought a brad nailer(already had a compressor)
So much easier!
I don't know why I waited so many years, and tried to do so many projects, without one.

i have a few sets of these: http://www.rockler.com/universal-fence-clamps-with-clamp-it-square

that can keep you on spec while the glue sets up

a few (4) ratchet clamps can be quicker for set up with the just the plastic parts

and Rockler does sell a set like this: http://www.rockler.com/clamp-it-assembly-square-6-pc-kit

but mainly you can get by (i.e. > WANT!) with just the corner clmaps and get cheaper just a good clamps off amazon or whatever your resources are

since the HTM12's aren't so large I suggest 2 of those corner clamps

as the glue can slide you out of spec too, think of using stops blocks, etc. so things stay put . .

Cheers for that. I actually bought a band clamp and some 24" quick release clamps along with a couple of 12" quick grip clamps and 4 x corner clamps.. I think that should be enough for the build but will buy more if necessary.

I think the method I will use is build the top, bottom and sides first, glue them all together, then glue that hollow frame to the back panel. then glue in the horizontal and vertical braces. I am going to get my MDF cuts this week. :)

some, but not all , would start with sides 1 or 2 at a time being glued to the back

that way you have a better chance of keeping the sides all squared up 'cause the back is "square'

i wouldn't want to have to challenge the glues joints by maybe needing to handle squaring the assembled sides all at once to the back piece

it seems that controlling 4 sides at once wrt to keeping them all in the right alignment / place is more challenge than, for me and IMHO, than I would care to opt for

from my lessons in working with BFM plans, get each board right , 1 at a time and be sure to hit the mark . .

then get the next 1 right . . . .

and so on

Quick update.. I've just been to my local B&Q and the guy there was very helpful.. He cut all my pieces to exact measurements and now I have got them back home and doing a dry fit test before I glue the top, bottom, left and right panels together.. Here's a few photos.. Fingers crossed should hopefully go all well

It was a bit tricky with the band clamp lol but all ok now.. I have glued in the first one and applied reasonable pressure both on Band clamps and the quick grip clamps.. Any idea how long I should leave it in its clamp status before taking the clamps off? I mean I don't intend sticking the back facia today but I can then move on to the next one if I can remove the clamps.. I'll leave the clamps for a few hours or even till tomorrow no rush but I just didn't know how long is reccomended to leave them on.. Would appreciate some advice please..

Also the corners seem pretty flush and square as I used my square to check afterwards.. I cleaned the excess glue from the outside case to minimise any sanding later on in the build however left the inside with the excess glue as can be seen in the pictures... Hope this is OK to do?

Welcome to the club!!

You're off to a great start, they look perfect so far. Nice squeezeout inside to ensure a good seal, and square coeners. Don't need much else from an enclosure. I would be remiss if I didn't add my usual "you can never have too many clamps!" comment, but you can often manage with whatever is on hand. Looks like your band clamp is working nicely.

Keep at it, take your time, and enjoy the build! I'll follow along to see your impressions. These really are great speakers. I can't wait to get mine up and running in a proper setup.

Thank you brother. Much appreciated :) I will keep the thread alive as I continue to progress. Tomorrow I will do the second speaker box and post an update.. Thanks for all your help guys!!!

Right.. Off to bed now guys, however I just couldn't sit still lol.. I figured the clamps had been on for over 11 hours so was safe to take off and glue back panel for the duration of the night so that's what I did .. Tomorrow I'll start fresh on the second box fingers crossed after a few things I have to do in the morning.. Will update with pics as I go along.. Good night all...

It's a shame I just read your post now.. I may have done it that way.. I think I may give that ago on my second box. lets see how it pans out but the first box seems perfectly aligned touch wood :)

nice "flow",
hope it inspires others to appreciate well applied basics begun with the end in mind

not every DIY project "needs" a Manhattan Project mentality

but it can be fun at times

especially when you get to fire them up . .

Today I managed to knock up the other two boxes.. Back panels glued and clamped.. Will probably leave the clamps on until tomorrow evening as I don't need them for anything else and once that's done I guess I'll need to wait for the front baffle and parts before I start cutting out and installing the vertical and horizontal braces into each box.. But this is the current situation as can be seen in photos below :
