Its about time! ;-)

You should have more than enough headroom now!:bass:


The P-84 Elliot Sounds EQ sounds interesting, is it only doing "EQ" or can it be used as crossover/buffer at the same time (and providing extra gain)?

Cheers,

Bert

...it can be used as buffer. This would suit my needs for the REF2010 as it "needs" an extra stage (buffer) if EQ is desired so that you do not need an additional subwoofer...

Looking at the IC's it can be modified to give more overall gain too if needed...

I guess I have to order a few boards and start testing and modify to make it fully compatible and being extremely flexible with the REF2010 in combination with all the Oris horn options.
Let's see if I can make that work... :read:

I bought LME49723 smd opamps and soldered them onto Brown Dog DIL8 adaptors from Cimarron technology in the USA(no job for the faint-hearted!)

congratulations... and thanks for the pics. That's an impressive, and somewhat 'scary' set up.

twin BD30's... you shouldn't be so greedy... don't you know they are in short supply :wink: (i'm just jealous because I didn't buy some when i could have)

he-he
I should have bought another pair for backup! or even if I wanted to tri-amp some time in the future
besides from that:
this rig moves some serious amounts of air!and with great finesse and ease as
well;very laidback
it also affects the total sound of the system over the entire frequency spectrum
junior of 14 with his own Altec setup, came up to inspect yesterday night ,when LCH was ready and he put on the latest Eminem@full throttle,which gives the towers some serious massage:grin:
he went over to feel the sides of the cabinets and he couldn´t understand that they were playing at all; no vibes whatsoever.
fantastic construction and highly recommended:cool:

hello again
have now started to get closer to a more "final" crossover solution:
ordered 2 custom XM46 130hz 24db/octave passive line level low pass filters from Marchand Electronics
made 9db L-PAD with Audio Note 2 watt tantalum resistors to match to 300B output
filter is on input of Rod Elliot P-84 eq-board and then to dual BD-30 amps
this really cleaned up everything:
much more transparent total sound
tighter bass
really pleased and the supertowers driven by the dual BD-30s really shine at any lvl/material
excellent build quality and superb service/support from Phil Marchand
just as from Bert
a pleasure to deal with
highly recommended!
