Default Looking for WAF helping advice

Hi all,

My first post here, I have been lurking for a year or so figuring out what I wanted to build. I have built two amps, now its on to the woodworking part of the sport...

Based on lots of reading of recommendations to others and comparing to my listening requirements, I have settled on a Curvy Chang build with a FE 207 driver in BB.

Now, to the fun part...I am on the wrong edge of passing the WAF test and I had an idea to tip them into acceptance...it did evolve after drinking a fine amout of beer one evening.

So, I need your input. Can I build the CCs into built in bookshelves or am I asking to turn the whole bookcase and the gypsum board wall into a resonator with awful results?

Thanks,
Steve

They will be housed in a large room, 25x30ft with 25ft ceilings and the bookshelves would be in corners of the room extending out 10ft, so placement has some variance.

It would be an interesting experiment. But...

No opportunity to play with toe, in speaker separation, pull out from wall for less bass (if needed) better imaging...

Also -- it isn't going to be easy to hide the curvy bit.

How about, building, getting placement right, then building bookshelf around (or stand in between)?

Have you got 207s already?

You're going about this the wrong way. First you find a pic of the biggest horns you can find and tell her you're building them for the living room. These should do the trick (see below). When she regains consciousness, you pull out the pic of the Curvy Chang! You'll be surprised at how much more favourably she'll look at those babies

you could start your negotiations with :

electron luv | hi-fi vacuum tube atomic age audio, amplifiers, guitar amps, speakers, horns, Salt Lake City, UT


then settle for something like Scott's delightful Maeshowe (shown here with Mark Audio/CSS EL70)

what a deal - audio system and relationship counseling - your one stop shopping center

with that kind of advice audio won't be the only thing you'll be DIY-ing

Ummm.... Similar to some of the designs here (speakers, amps, etc.) the theory suggested here will be satisfactory to some, while for others it could be rather costly and might not suit their needs. As with any design there are trade-offs. For example - the new woman may very well like CC's - but wishes you had a bigger woofer, or bass bin, or more expensive and refined taste in the wood working department. YMMV

OTOH - your current spouse model might be able to be modified, tweaked, upgraded to meet your needs. See the forum on flowers and candy - and for high end upgrades - jewelery.

As a last resort there are a number of forums available over in relationship counseling - and as a last resort - legal advice.

ITMT - I thought that P10 had some CC's for the Fostex - but perhaps I'm thinking of the Mark Audio drivers???
Take a look at - Need Complete Home Theater EL70/CHR-70/Alpair 7

Hey - we feel ya - and we are here to help!!!!

whatever that means

CC = Curvy Chang is for FE207. Maeshowe is new Woden Horn for CHR/EL70 (althou A7 seems to work accepatably).

The Fostex V-Bomber series are all similar, the one for FE126 only slightly changed from Maeshowe. These 2 fit into a sheet of 5x5 BB, the other 2 are larger.
