Hey pete, I was directed to you for help . I want to breakdown my vince's vht's and do an mtm with just the vifa pl27 and the da175's from that build. I was wondering if you had a crossover for this? Thanks for the help, Bob (bobbeyo@yahoo.com)

yo Pete, would you mind take a look at my last post just now ? thanks a millions!!!

I listed a post could you and your friends Please look at it and help me out

hello Pete Schumacher - I'm new to this forum, but not to audio. I cruised around and read some of your stuff, along with that of others here...and what I'm looking for is a bit of sage advice.

I recently purchased an NEC AVR-1000E on ebay ( Dolby surround processor/reciever with their scrumptious on-board amplifiers ) and therefore am contemplating speakers to match this unit...2 mains and 2 (or more) surrounds. I initially wanted full-range single driver mains, but after seeing the prices on the 10" Hartleys...I might have to reconsider. I've read about the Fostex drivers, and researched other options online, but haven't actually decided yet.

Also considered building a 2-way, with the stipulation that the crossover be outside the vocal range ( 5k or above ), thinking this would be an acceptable compromise to pure FR mains. I particular, I looked at the peerless 830884 - for its ability to go high, yet still allowing good bass extension...mated to the vifa/tymphany XT19TD (?)...or possibly a planar or ribbon ( ? )

Anyway - I want to take advantage of what this receiver has to offer ( it has a surround mode along with what I guess is a "panorama" mode ( ala Lexicon cp-3 ) ( cross-channel cancellation ) which NEC calls "holographic". I have a case of 4x6 drivers ( 4 ohm with wizzers ) that I'd like to use in the surrounds...possibly direct/reflecting ( Bose 901's)...so the only real question has to do with the design of the left & right mains. Should I stick with the full range single driver design concept, and if so, can you suggest any drivers ( 4 ohm ) that can actually do this task ( I know the Hartleys can !!! @ $700 a pair !!!)...

Or should I continue considering a 2-way with an above 5khz xover...or is this simply not do able ? I really don't want a setup that requires an active bi-amped sub, so I kept looking at drivers in the 8" size range...hoping to find both the LF extension AND the ability to cover up to 5khz or so, thereby maintaining the "wholeness" of the FR drivers.

Any advice would be welcomed - email direct if you like -

thanks much - michael d

Thank you for your input on the Nuts? thread. You pointed out several things that escaped me and I really appreciate the guidance. FYI, I hand sketched the three-way you suggested it got preliminary wife approval today. All drivers on the front baffle though, behind a grill. Its the leading contender and the simplest to build. Again, thanks a lot for your input and guidance. ~ Scott_M

You have a valid point Pete. I uploaded a few pictures to see how it worked. They warrant more detail. I'll put it on my "to do" list.

Hey, Pete--
I'm finally near completing the 2.5-way quad DA175 system I started long ago--there have been a variety of setbacks--I first discovered that the garage needed a new roof before I could get started, then the Patriots Day storm here in Maine resulted in a tree falling through the new roof, and a flood, on a hilltop yet, swept down the driveway and ruined the nearly completed enclosures--they were originally a sandwich of 5/8-inch particle board and 3/8-inch plywood. I started afresh after the garage was repaired with what I know best--3/4-inch voidless hardwood plywood. I've styled them sort of like PA enclosures. I was wondering if you'd be interested in looking at the write-up so far (it's kind of long). I could send it to an e-mail address as a PDF. I'm also working on plans for a wide dynamic range system utilizing pro drivers, and I built a Moser Project variation using an 8-inch PR for my sister as practice for rear channel speakers for our living room once the quads are in place.

Heya, Mr. Schumacher
I posted on the Tech talk site a few days ago. The short of it is I ordered speaker components for the left, right and center channels for a modest home theater set-up in my basement. Actually, a friend picked out the components, I just remodeled the room. I have no idea how to make speakers,... my friend was supposed to help me with dimensions for the boxes. He got a job out of state and I now have 600 dollars of stuff in my basement. I posted what I have, and guys pointed me out to your website. You used the smae Dayton DA175-8 7" speakers in another project. In fact, looking at your website, it looks like my basement in your projector photos.
Joe had intended a woofer tweeter woofer woofer speaker config., so I have 3 woofers per left and right speakers, and 2 woofers and a tweeter for the center channel. The tweeter that I have is the vifa D25AG35-06, one for each speaker. The speakers you made basically look just like the ones I'd like to make. Heck, I'll order another two 7"s to duplicate yours, if you don't mind! Do you like the vifa tweeter that I have? What config. should I use for the center channel? I have an Onkyo 805
7.1 receiver. I planned on getting the Titanic 15" sub kit and some ceiling speakers to round out the set-up. I have 5 months to figure this all out, I'm playing Mr. Mom while my wife works on assignment in Kansas City, Mo. for G.M. I'm about 900 mile from my mdf and tools. I've had these components since Nov., and my wife may sacrifice me during the winter solstace, so any help would be appreciated. Oh, and Joe had me order the PE 3way xo and their 2 way xo. Those won't work, right?

Thanks for any help you can give,
Ed Rosenquist
