Well I see what you mean about the three bolt holes not having very much room to work with. I think the DNA-360 was designed for 2 bolt drivers...
I finally got around to a revamp on this design after some input from Travis and to better match the SEOSR mains for Jake (chopshop). I posted...
The BMS 4550 does have slightly lower distortion then the DNA-360 below 1.5k, but also has slightly more around and above 2k. However the TD12M...
I added the files in a zip folder and attached here.
The online calculators assume a flat frequency response and impedance while the FR and impedance of most loudspeaker drivers are not quite as...
I also suspect the woofer cap. Try disconnecting the cap and 3 ohm resistor at one of the ends and see what happens. If you have a multimeter...
Nope 650hz is the correct number for the woofer xover setting. There is some boost at 1100hz (6dB) which brings the response up before the actual...
From what I can see it looks good.
I think it looks good, connections are correct as far as I can tell.
I picked up a couple of those from the PE tent sale this year. I planned on doing something with them but who knows when I'll get around to that...
Hmm.... $1000 in speakers does not leave a lot of choices for a 7.1 system. You could possibly go with Karma-10's for your LCR and Karma-8's for...
What is your budget for the speakers? Any size limitations for surrounds (or behind the screen)? Do you want to build your own enclosures for...
I just finished up this design for countrywv he sent in the 4550 and I had a TD12M from Brain6751 who sent that over for a in wall project that...
I usually try to start with whatever gives me the best phase tracking through the crossover, but the second order with notches gives me a little...
These should be pretty close to the passive design, Woofer: 3rd order BW 650hz EQ: 500hz, -2dB, Q=0.5, 1100hz, 6dB, Q=1 1600hz, -20dB Q=3...
I have a somewhat similar dip on my measurement even with the port sealed. The port resonance with the slot ports included is around 1700hz, it...
If you are crossing over to a sub model with a highpass filter. IIRC most avr's use a 2nd order highpass on the speakers and a 4th order lowpass...
1100-1200hz may be a little low for the DNA-205 when run at higher volume levels. I dug up two of my measurements for the 8PS21 and both show...
Probably close enough that you would not notice with the playback of regular material.
I am switching the current Dayton (JBL clone) waveguides and DNA-150's that are on it out for SEOS-12's and DNA-205's, woofers will stay the same....
