Thanks Danny! One nice thing is that I can easily move the ones in the middle when occasionally watching movies. I can store them away and the process takes about 30 seconds. I treated the left wall with 4 absorption panels as per your suggestion.

Thank you Delta77 I appreciate your comment.

A little over 20 years on and off but the only experience I had with open-baffles in my system was a pair of Magnepan SMGa back in the days. My audio journey all started when I was 16 and decided to buy vintage equipment rather than visiting the usual stores...a nice MC240 tube amp and a pair of Kef 104/2 speakers for the equivalent of US1500$  :green:

Jay!! Thank you so much for bearing with me and investing so much time in my project. I would recommend your flat packs to just about anyone! Especially when fully assembled/finished haha  :green:

David,

Those look great! Glad you got them up and running. Now for the fun  :thumb:

When you are ready to install the No-Rez, if the insides are slick and shiny, be sure to scuff them otherwise the No-Rez won't stay stuck.

Mike,  that  no -rez will  not come off that paint... it  grabs it unbelievably well As long as it's clean, no dust,  it will   not come off.

Jay,

I've had it come unstuck when applied over a smooth topcoat so I scuff sand with 320 or 400 grit.

gotcha, maybe it's the type of  finish ?   No issues with   this  high quality automotive clear coat... the self adhesive of the no-rez grabs it and even if you don't   press it, it's  damned hard to get off.    I've stuck no-rez to  quite a few different finishes and so far,    this clear seems to be  what it likes best.

Quite possibly. I use finishes designed for furniture.

The modular 2x12 H-Frame flat packs from Jay are here.  Danny sent 4 - SW-12-16FR and will be here tomorrow.  The HX300's, connectors and cabling are here.

Time for some gluing and installing during the holidays!

Finally got busy and glued up another set of amp boxes.    Wrapped them in   the leftover  Applewood (Tineo)



these will be sprayed in flat  lacquer to match  another set of Applewood subs we have here..

Here's a few  pics  after  some  low sheen lacquer ( I like the look of  this on wood) and fitting  an amp.




Now this pair of Applewood  "demo" fianlly have their matching   amp boxes

Hi all,

Very inspiring and most impressive work here.

I am a newbie about to pull the trigger on this project but still tying up some loose ends in my head as I formulate my plan.

Regarding the materials:
  • Now that you are using the 5/4 Medex, do you notice any kind of sonic improvement or degradation over the glued 2 x 3/4 MDF sheets approach in your non modular design?
  • Anyone have arguments for or against using Richlite for the baffle or even the whole H Frame?  Price might be a negative for the whole H Frame, but would it improve sound as a baffle?
  • Finally I am a 3 sub per cabinet kind of guy on a 2 sub per cabinet budget.  Would it make sense to build a cabinet for 3 subs with the intent to add the third sub later, or would this just be adding an extra unused chamber to resonate until it is properly fitted with the 3rd sub?
Thanks,

-Dan

Hey Dan
With our kits (both modular and non-modular) we use a 1" bafle,  it's actually a bit  over kill but  it  does eliminate the  issue of the screws poking through the rear  roundover. ( I like to use the radius on the  backside even with  subs)
There is such little baffle  in each  "chamber" that   a different  material is unlikely to  change  the sonics... resonense here is not an issue.

Our non-modualr kits use 1.5" MDF not a pair of laminated  .75"  sheets.  I did build  a couple  pairs early on using the laminated sheets....  pretty hard to say   if there is any difference. 
I have not noticed any difference  in  sound between the  1.5" MDF and the 1.25"  Medex... but the  1.25"  Medex is    denser, resists moisture better, and seems to be  more  durable  ( less likely to  ding a corner  etc).    We recently sent Danny  some prototypes of a  different cabinet,  I think he was surprised at   the difference between the two matials.

If you   built  the  subs  in a modular fashion, you cold  build them as duals then add a 3rd section   when the time came.  If you   definitly plan to migrate to triples at some point, be sure  you  order the  SW12-16FR's, the  8 ohm versions will not work for triples.

I also recommend you  use the no-rez  in your subs... when you  are  going  with a set of subs  at this level, just do them right  ... right from the beginning.

Thanks Jay,

Overkill is AOK in my book.   :D

Sounds like MEDEX is the way to go.  All my research said it was very easy to work with and better than standard MDF, so I am glad to hear that it performs better too.

No-Rez was always in the plan.   When we are talking about a $2k plus project, doing them right is the only option.

I was not able to find a price on the modular flat packs, is it the same as the non modular prices posted at the beginning of this thread?

Thanks again Jay!

Prices for the modular subs wil be  $150 / module whichwill include the bases ad tops  for each tower (so for example,  a set of duals is $600,  hardware is included).,  .   We'll be going to a single sized base/top  on the next run..  I do need some lead time on these right now  ( I've got 4 modules  but no tops/bases  for the towers.    No  grill frames  are programmed yet but we may be able to accomade  them.  amp boxes  are   as priced on the first page of the thread..

Jay,

I am interested in a pair of open baffle subs. I have a few questions about the flat pack, could you send me a private email?

Thanks,
