thanks man !

I mean do a thorough testing of the complete system. The consequences if you don't can be severe. SO i WAS intending to test these cabs with the t48 Friday day time before they went out into the world that night- but medium disaster struck . For some reason when they were finished (well, finished b...

Good news about the piezos .

By wring out , do you mean play loud?

if so for how long ? or do you mean just to make sure its all working and sounding good?

Amazing !

so much to think about and work with here... hopefully i get a chance to try out what you've suggested tmrw night ... before the debut friday night!

im excited !

thanks for sharing your knowledge and approach

pizzzzo.jpeg Piezzo time... better late then never .. im working against the clock , these speakers are meant to be for their first outing on friday night to an audience of about 100 peope :/ i cut them before testing which wasnt the smartest... Just finished testing now with pink noise on the gold...

I couldnt source any "flexi" or "bending" ply in time and as the supplier i was talking to was so insistent that his 3mm Birch or poplar wouldn't make the bend. I went for two layers of 1.5 mm birch per bend. The 1.5mm i got is of a very good quality and much cheaper than buying ...

Best to arrange a limiter, it'd be a shame to torch your drivers with an accidental nudge :broke: do you think it is : A. not safe to limit in the way I have been, even before my attempt at EQing? B. not safe to limit in the way i have with the boosting i then did in the eq in the low end ? or C.do...

Hi Keryn,

thanks for your reply.

i have read the sub placement guide, but had missed the EQ settings section. will check it now !

Ok after a bit of playing around today i understood a bit better how the Low and Hipass curve is then mediated by the EQing I crossed over higher for now as my temporary mid/tops weren't really reaching down to the sub . Ive boosted abit in various places to get the steeper curve i was talking about...

Over these last two weeks I've been working on a pair of DR200s. I've been using glue drying breaks to sound test my T48 . For now i've been using a pair of old car 6by9 coaxials in rear shelf wedge type boxes as stand ins for the DR200s. The Titan in question is a 2 x 12" loaded, 30" wide...

the sides of that part should be 1¼", resulting in a 1 3/4" wide hole

you are indeed right , i was reading the plan wrong

but happy to know that none of this matters

The build is coming along, and i'm enjoying it in all the spare time i can get : dr200 build 1.jpeg Dr200 build 3.jpeg DR200 build 2.jpeg BUT I am having problems getting ply that will bend to the tight radius of the rear curve... The first stuff i got was trash - this is what numerous bits of it lo...

The sketchup differs from the plans when it comes to the rectangular cut out in the 12mm ply throat horn supports. As i had these parts CNCd from a file made from the sketchup half of mine have a 1 3/4" wide cut away and the other half have a 2 " inch wide cut away. None of my throat horn ...

Hello all I wonder if anyone could shed any light on whats going on with speaker hardware. com at the moment ? I was in communication with Leland about buying 2 xDR200 kits to be sent to the UK - minus the woofers. He told me to put the order through on the website and as its a bespoke version of th...
