Which design for CHP-70.1
 
Hi There,
This is my first post and first build... so hello! I've just ordered a pair of Mark Audio CHP-70.1 speakers with an eye to building a pair of FH 3's. Then I saw a thread on here about maybe building them into a woden design Coniston.
My question is what are the different sound characteristics of the BVR vs the FH 3? Also can the BVR be used in a room about 12'x14'? I actually prefer the look of the taller Coniston, but will it work and sound ok?
Any feedback would be very much appreciated.
Thank you

Coniston is really for the EL70, don't know how well CHP would do, but given Coniston works qith 1 or 2 EL70, i'd guess your chances are good. You also need to be able to get out at least 3m for the speaker to integrate.

Thanks Dave for the reply. It looks as if I'd be better to stick with the Frugal Horns then. The others were a risk with the wife I suppose. The real problem for me is to get a good 3m away. I'd nearly be through the door and in the kitchen at that rate :D
Before I start to build the FH 3's does anyone have any tips with regards to how to go about the build, what to do/what not to do etc.?
Cheers

Small digression :-) Bought a pair of CHP70 Mark 2's.. they proved erm.. disapointing. No Biggie as what can one honestly expect from a $40 driver.
Now broken in 125 ~ hours logged. Tried them again today. Initially sounded fine. Then noticed their Ssssiblance on Every high note.
It'ssss sssseriously annoying, rendering them usssssless for listening purposssssesss. Remembering that these are claimed as rolled off in the higher freqs .
My A**!
These are Chinee Crap speakers... period.
Gee who woulda thought Plastic chassis speakers wouldn't be outstanding.
Maybe I should Slather them in Ductseal and Fingernail paint Patterns on them??? Perhaps using Mr Floaty as a crayon.
IF you think these are 'good' then I can Only assume that the reviewers' reference points are completely inadequate.
Hey! some are convinced MacDonalds makes Good burgers too :rolleyes:
Clearly there's No underestimating North American tastes..something Long Proven and the historical basis for some serious Profiting.
I can accept that these Lillipution widgets are Not going to have impressive dynamics.. Dohh!
But It would be nice IF they could do a passable job on basic frequencies.
Note that this was tried on a long standing tube /ss amp setup which has NO sibilance whatsover.
Disbelieving, I retested using 2 separate speaker systems and then triple checked with 2 Headphones.
ONLY the Mark Audio crap things had Sssss's.
A Mark Audio issue NOT the system
Impressive product indeed !! Remind me to buy More :-)
MY Current opinion is that these cheapish ~$40 drivers have an effective value of 25 Cents...Maybe.
Yeah I'm a little pissed, Mostly at myself, for believing the internet Drivel in the first place.
Mine are going into the trash bin.
Caveat Emptor applies Kiddies :D.

Mr Bare is talking about his sole FR experience, the CHP-70.2, a quite different driver from the CHP-70 (original) under discussion here. And his mounted in a marginal box.

Still his comments about the top are pretty much mirrored in the factory FR data... a 5 dB rise to 6 kHz,then a rapid plunge 10 dB where is shelves.

Not Mark's best effort. And his best are very good.

CHP-70 Gen1 is a good driver. I have a pair, and in FH Mk3 it is a good combination.
