Default Wallmount/onwall design q's

Hello, long time lurker, first time poster.

Currently I have Onkyo xsr805 reciever, Jamo C603 bookshelf fronts, Jamo S60 center and Dahlquist QX-25RA rears.

Did some searching on this here and avs and came up with little info. The only answer I found I'll touch on later.

I'm looking to upgrade the speakers in the system and definatly want to go the diy route. I have extensive carpentry and electronics experience, but limited design and modeling experience. I would like to go the route of building someone else's design for a first. Maybe later I'd like to try designing myself.

I am finding the choices at zaph's site good for fronts and center options, but for surrounds I'm having some struggles. I know zaph doesn't believe in surround speakers, so I'm not expecting info from him on this.

The question is, most of these design's are meant to be placed out from the walls. I would build one of his designs for the surrounds, but I am looking for a design (in crossover and enclosure) that accomodates being mounted to the wall.

Looking to complete a 7.1 system. These will only be used for movies, as I only use stereo for music.

I was thinking about building his Slimline wall mounted design, but will this outperform my dahlquist rears. I'm all for building them and comparing, but the frugal part in me would prefer to get some opinions before I start.

I don't have a set budget per sey, but I plan to evaluate my cost vs performace as I go. I plan on going with some pro rack amps, crown or QSC maybe, later (part of the reason I got the xsr805, it has all the preouts on the back). Also I will be building the ZDT3.5, so would like something that would be a nice sounding match.


Thanks

Hello,

Try looking at this design from Visaton http://www.visaton.com/en/bauvorschl...ait/index.html

They are intended for music but I know that Visaton also have a brochure on their site showing them used as surrounds in a 5.1 system.

There is also this design from IPL acoustics, while not completely DIY as you have to buy a kit, still might provide some inspiration.

http://www.iplacoustics.co.uk/ipl_av...re_speaker.htm

There's also these guys http://www.occamaudio.com/, who sell kits but if you look under the designs/specs link you'll find the basic design specs i.e box dimensions, crossover etc. for their speakers.

I'm in the process of finishing a pair of the Visaton Portriats for my stereo system as I needed something that would hang on the wall since regular speakers were a no-go in the living room due to little people and WAF. They didn't sound at all bad, considering they use budget drivers and were my first speaker build, when I gave them a quick test.

Hope some of this info is of use/help.

Regards,
Ewan

Hi,

Checkout : http://www.spendoraudio.com/downloads/SR5%20manual.pdf

And http://www.zaphaudio.com/ZBM4-modeled-options-BSC.gif

A decent 4" is always going to do better than 3".

And a 5" design called the ZMV5 will shortly appear.

thanks for the replies. Those portrait speakers look very interesting, but not really what I'm looking for. Maybe a later project for a different room.


I had looked at the zbm4's a while ago and forgot about them. Maybe I'll have to build a set and do some comparisons. The price is definatly well below what my budget demands are. How long till he releases a design for the zmv5's? are we talking a few weeks or a few months?

Thanks again!!

There are wall mount versions of the Modula MT and MTM, as well as a couple other speaker projects with wall mount versions, over at htguide in the mission accomplished subforum.

If you can use a larger midwoofer, you can do what this person at PE board did:

He used my RS180/27TDFC 2-way's no-BSC crossover:

I'm also using the Vifa DQ25SC tweeter for my new 2-way design, but with a higher quality midwoofer than in Zaph's new design:

Currently two persons are building this design.

Hi,

Sounds like it will be good.

Regarding the RS180S / Seas design the tweeters are getting expensive.
And moving away from high bang per buck, as found in the DQ25.

What might be interesting for the dayton design is to redesign
it for a cheaper tweeter that is also available at PE, eg. this ? :
