ORION challenge to DIY
However, it has always been hard to justify setting aside $$$ for 8+ channels of high end amplification, electronic x-over and then the astronomical prices of SEAS/Peerless drivers. Not to forget the cost/time needed for the enclosure itself. Until now...
I got a screaming deal on a pair of SEAS W22EX drivers last weekend so it has officially begun:
For the tweeter, there is now way I am going to drop $1000+ on two pairs of Milleniums. Enter the BG NEO 3 PDR:
Bohlender Graebener Neo3-PDRW Planar Tweeter w/Back Cup 264-735
Excellent off-axis response and removable back cup make it a good match for open baffle use. And affordable! Plus a little different, great for street cred
As for the woofers, I am not keen on spending another $700 on the Peerless XLS woofers. However, Peerless has a driver that happens to be a be better suited for open baffle use and costs less than half as much, the 10" 830668:
Peerless 830668 10" Paper Cone SLS Subwoofer 264-1110
Not as much Xmax as its XLS big brother but QTS is much higher and the price is right. Two per side in an H configuration with 120 watts gained down should do well.
The other option I may try is the Eminence Alpha 15". I am also a big fan of the Jamo R909 and the Legacy Whisper so these would play into an interpretation of either design. Plus a wall of 15's looks pretty cool
Eminence Alpha-15A 15" Driver 290-407
I'm in a small high-rise right now but my condo is supposed to sell by the end of the year...if it does, I'll be more inclined to go the 15's route since I will be moving into a large house, perfect for the large format sound that the 15's will deliver.
Now, onto the amps and crossover. For a crossover I'll use a DBX 234 proaudio unit:
These are on ebay buy it now for $129 refurb'd and just need mono 1/4" to RCA adaptors for home audio use. Very flexible and only one required for a pair of 3 way channels. Very good feedback on diyaudio.com regarding noise floor and performance.
As for amplification, there are a number of amps I am looking at and it all comes down to the best deal. I have an offer in on a pair of Rotel 6 channel amps locally here but I have a feeling it will fall through. If it does fizzle, I may end up with a pair of Elan (Sunfire) Z660 6 channel amps, one channel per mid/high and two channels per woofer (60w per channel or 120w bridged). Or a pair of Adcom GFA 535's for mids/highs and a 545 for the woofers. The great thing is that all of these combinations are $400 or less all day long on Craigslist or Ebay. MUCH less expensive than anything in Linkwitz's plans but all comparable performance.
Next week a contractor friend of mine is taking me to a local exotic wood shop where I will pick out the mid/high baffle. Everything else will likely be 1" MDF, likely piano gloss black but I am still looking at other finishes before committing to that.
And there you have it. I'll be sure to continue posting updates as the build progresses. Stay tuned!
