3/4" mdf open baffle with 2x4 bracing
@kan3
Very interesting!
How deep is the bass of such open bafle? Do you use some kind of EQ-ing?

These are the mids that were used:
http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=299-492
I really haven't got to play with them much and have only done a quick RTA of their current position but response is usable to the 70-80hz area - for my tastes anyway - without any eq. They are butted next to the corners of the room they are in with about 15 feet center to center spacing and about 3 feet from the center of the baffle to the wall behind it.
The girlfriend wants to move the living room around(been saying it for about 2 weeks now) so I've been holding off on proper eq/crossover adjustment, about the only thing I've sat down and done right is level matching. All processing is done via computer.

hell i just ur average high schol student been intrested in audio for a year now but the system i got aint spectacular
60$usd-yamaha reciver 230watts 80/channel 5.1
free-boston acoustics a40 ( manufactured 1984 )(different mids)
free-(not sure what make ) the fish xp56 (70s)
(50$)-alpine type e 10inch 600watts in a custom ported box
free-a sub amp of my fisher stereo i think 125watts
free-and still expairmenting with a 8ohm .5 inch horn 4*10 tweeteer

That's an attitude I saw in my daughter, who never seemed to get it to kick in while in school. She's a smart kid who has had a string of dead end jobs after high school, trying to get back into the school mode.
Just a hint: Speaking and writing well will get you a lot further in life than raw intellect. 😉
BobEllis, I agree. My Technical Writing prof said, "if an engineer doesn't get a promotion it's because he is unable to write ineffectively."
lynchingacers, hate to knock you on school at all BUT I'd bet that 99% of the ppl on this forum would like a second chance at school so, do once and do it right. Also, you have a MUCH better system than I started with! Free Boston Acoustics! NICE!

they were being thrown out but i wish i kept the mid frames cause when i got the boxes the mids were shoe as far as cones and i tossed them then i saw rebiuld kits later

This is my 14 year old construction, made off PVC and MDF. I still enjoy them after all these years...
Vifa woofer, Dynaudio D54 dome and Visaton RHT 12S ribbon. Subwoofer contains 4 Sonic woofers (6 inch). I use a valve amplifier with 8 EL 519 tubes 35 watt class A (2x 70 Watt max.) and a Marantz CD 17.

thank you...
I designed these spaekers after looking, listening and reading about the Elipson, B&W and Jeane Marie Reneau speakers who use a phase liniair concept. The coherence of their sound was realy good, even for a 3 way system. The very heavy 54 mm dome midrange from Dynaudio is the hart of my speaker and i let it work from 600 - 6000 Hz only filtered by one capacitor.
My brother disigned the tube amplifier and used some special trics like introducing distorsion to reduce distorsion, normaly all designes try to avoid! The result is a very low distorsion for a tube amplifier below 0,35% at full power. This amp is DC coupled and has no C's in signalpath and a double powersuply.

Well, here's an ok pic of my own system. It's using a redesigned thor, with a 2-way section using excel drivers up top, and a 8" sub on the lower back. They've been in my system for around 7 years now, ever since I got them from zalytron. They've got great imaging, midrange and soundstaging, and the subs also extend quite nicely into the lower ranges -- I use a sub sometimes for movies, but that's it. My source is a Meridian 586.2 DVD player and an Arcam AVR200 handles switching and amplification. 🙂

my system
hi,
here is my system, i am a student so i have little money to upgrade.
the Technics SCHD70 was £100 of ebay 2 years ago and the Tannoy DC1000 were £90 of ebay 2 months ago, i also have a Fergurson R115D DAB radio.
Sounds good, i want to upgrade to a second hand Denon component system soon.
Pic below, i do have 2 speakers, they just wouldnt fit in the pic.

Bose(o), BobEllis,
I agree with what you say; Letter writing skill is best picked up when young.
Unfortunately, in my experience, such skills were acknowledged with scorn. It could be because I work in a different part of the globe where most bosses have an inferiority complex due to their inabilities.
Lynchingacers,
I'm sure you can write better, you were just a tad lazy at the time you posted.
Regarding my system,
-Phillips DVD player
-JVC HT AV Receiver(100W x 5, I doubt it's true)
-DIY mains speaker(wave cannon-back tube only) using 3way
Pioneer Car Speakers & RadioShack piezo horn loaded Tweeters
-DIY centre(wave cannon) and rear speakers(Bass Reflex)
-DIY sealed sub using Sony Xplod driver
-200W Sub amp Car type powered by 40A Transformer(240/12V)& Bridge Rectifier
I'll post pics when I find $$$ to buy a nice digital camera.
Regards,
Francis

Mr Noodle,
I have always appreciated when you can leave the XO external for further tweaking if necessary.
What are the cabinets made of?
