Richard Allan cube

Unread post by Latteman » Wed Dec 19, 2018 10:51 pm

A win on eBay made me the proud owner of 3 Richard Allan drivers CG 12 @ 15 ohms, CP8 @ 15 ohms, a CB4 @ 8 ohms, crossover and a set of plans for a 3 way construction.
Instead I made a cube construction, 12” top, 8” & tweeter firing forward.
Please follow the links for pics.

Currently bi amped as the right speaker from 2 A20s. 12” & 8” in parallel and the CB4 it’s own A20.
No caps or resistors as I have no spares at the moment but playing as the right speaker opposite my smaller cube. I’ve lifted it off the floor with a short legged turntable stand as a temporary measure until I decide if I like it

Top work Mr latte. Recycling at its best. What old furniture did you butcher to make them ?

I often thought about upfiring my 12 incher and 5 inch mid but that made the top panel very big. As you know i have my 12 incher forward firing and mid up firing. The oppposite of you - interesting.

Thanks for the positive vibes
I’m gutted I only have one as these drivers don’t appear very often and at decent prices, got these three for £25!!!!
I recycled a vinyl storage cube and desk top from the kids bedroom we are Re decorating. If I don’t source more Richard Allan drivers I will go with Richard Dunn drivers 😉😂👍🏼

Initial listening is positive,

I made this a while ago and set it aside for a set of cube 2 clones pictured else where.
With the recent purchase of doc modded 8” drivers and tweeters I was going to use in the cube2 clones I was instead able to complete 2 large cubes as I also got 2 12” Fane POP 50s. (4 actually- more of their role later)
Unlike the forth coming BBCs I have tweeter & mid bass forward firing & 12” up firing.
1 A20 to 12” & 8” series / 1 A20 to tweeters (cap filter used here)
These have taken a few days to settle in and for me to get the support and positioning right.
Reading many posts and adapting ideas to suit my room and available materials to hand I have hopefully come to a happy point- suddenly they are in focus, pleasing bass, information detail and a sound stage I can enjoy. Music sounds effortless- I now know what disappearing speakers sound like lol
What did I do?
The additional Fane 12” drivers are glued to the base of the larger cubes- these are then placed in the hole of the top baffle of my cube2 clones )vacated by the driver)- the cubes are full of play sand and the cradle of the 12” driver is thus supported. Such a big difference- I’m very pleased
Aesthetically a coat of black paint will improve that- pics to follow
