Group Buy for single driver speaker build

[apk]

I have one doubt and cant help but ask it:
How will the Mark Audio drivers fare in a horn loaded design? I am confused between Fostex and Mark Audio. fostex are said to be better suited for horn loaded designs with some proven combinations. At this moment a horn loaded design is the one I really want (am advised).
(Reason for asking: I have been guided for horn loaded design for my taste of music.) Either reply or PM me. Don't want to dilute this good thread
Thanks!

Rohitmusic,
My doubts exactly! I have also been comtemplating getting either the MA or Fostex, but confused about which one. BTW, the frugal horn mk3 design is suited for a wide variety of single drivers, including the fostex 126 and MA CHP70, CHR70, alpair 7 etc. Bibin from our forum is planning to make a frugal horn using fostex 126. I have read about a few builds on diyaudio forum using MA in the frugal horn design and the owners seem to be quite happy.

I guess I am taking this thread OT. Will continue further discussions on foxtex vs MA in another thread. Apologies to the OP.

APK.

Is a 5.0 recommended with FR drivers?

yes. very much. but sub needs to be added for movies to push to higher SPLs. crossing above 80hz will reduce stress on the cones and then they can be pushed to greater volume without distortion

updated list,
1. sashijoseph ( qty=2)
2. magma ( qty=2)

Sorry i jumped the gun ...my idea is to build a open baffle (with locally available 2 x12 inch Alpha or beta per side).

Using MJK worksheets the Alpair doesn't model well (while the L CAO 6.5 Alnico does with Alpha 12)

Sorry again.

I saw that link its a kappalite 15 on a h frame, I'm looking for alpha or beta 12 in a open baffle.

But one good thing is the Alpair would not require a super tweeter.

alpair12p is better suited for OB as i have read on diyaudio. couple it with bigger woofer may be 15" or even 18" pro. such combination may achieve real live performance kind of sound reproduction as both could be able to move pretty good amount of air. however u may need a super tweeter in case of alpair12p but it depends on your listening tastes.

magma ,
yes my build is in mdf .

hmm
good call

though Bob recommends PLy
i have found ply not be as dead as MDF
it tends to play along

in some designs the resonances that ply has "works" with the driver and speaker
But i try not to make those bets

im guessing you figure this too
or was it that MDF is cheaper / and or easier ?

 

[manuduggal]

hi magma ,
no I had not figured it out . hfm "kaushik" suggested for mdf . I had actually not given it much a thought . but neither did I hear much about ply either , w.r.t. speakers.

I did not check the rates for ply .
but I'd say ..... ply or mdf these speakers ( mark audio 10.2) are awesome since the cabinet design is so simple and yet they sound so great .

Can I join? A gold pair and a cabinet built by magma

 

[malvai]

I'm in for a 10.2 gold pair as well.... if still available!

 

[kaushik]

in reality the GB will pull 4-12months and there is no rocket science for the cabinet buillds for Mark audio 10.2 ,so why wait ?

how big will be savings ?

Think about this :

most drop shippers will deliver 1 pair of drivers here in 3-4k shipping say 2k duty (addition to the driver cost) thatz it
it is a 15day ordering job.

you will hardly get 200Rs dicount for buying MDF /ply in GB .
labour also will be minimal as the design is very simple .
The cabinet build takes 1 day without finish with wood veneers.Same day evening you can start listening and let them burn in .
The outer can be sanded and veneers can be applied on any other freeday (very nice looking veneers 570/- a sheet )

guys, any update? how do I pay etc.
