thank for that.

No problem. Were you thinking fullrange or were you going to try a multi-way design? Coupled with a sub, fullrange can work very well.

If this is your first speaker project, I also suggest going with a proven design. Those generic drivers you listed could be used, but you will likely need to measure them yourself and I assume you do not have the equipment to do that. The designs on the zaphaudio website are very well regarded. Myself I am happy with fullrange systems. My hearing is not what it use to be.

I have decided to go with the hiVi home theatre speaker system,classy looking speakers.I have started with the HiVi Center Channel Speaker Project, just started putting together the MDF body.Parts Express will ship to the UK which is great.One thing I'm not sure about is weather the Denon AVR 1909 would be a good match for this system I see the nominal impedance of the centre channel system is 4 ohms, Denon only go down to 6 ohms in there spec.

I have burnt parts of my system by mismatching like that. I dont know what the specific ohms are on your HIVI but I know my 8Ohm speakers are really about 6.83Ohm. No problems, but my amp is supposed to handle 6 and 4 as well. In college I had some 2Ohm Acoustic research speakers and burnt them up in a few hours on my Kenwood receiver. I dont know why it burnt them, but the mismatch obviously ruined the weakest link in the chain.
Ever consider building your own amp? Its really pretty easy to do and can be quite inexpensive. Maybe this isnt your cup of tea, but you can pic up a surround processor and then have it control a few DIY amps to run your speakers and you will have something that (probably) will sound better than the Denon and that you built yourself. No disrespect to the Denon, I am just trying to suck you into this nasty rewarding habit we have. Its truly a lot of fun and you dont need ANY high tech equipment. Just a solder iron, solder, wire, and some components. My LM3886 sounds WAY better than my Harmon Kardon. No exaggeration at all. It blows it away. And of course they can get even better. There is lots of knowledge here and you will get lots of help if its something you would consider.
You can even buy the kits and then its just too easy This can cost as much or almost as little as you want.

Great stuff. Let us know how you make out and do post pictures of your progress. Yes, some HT amps do not like 4ohm loads, so you should look into that.

Cheers,
Gio

Nice work so far!

Have really enjoyed doing the woodwork for this project, the oak end panels were a real challenge, made them from a piece of reclaimed solid oak flooring. I cut a chamfer across each corner then used a file to shape the radius then I cut a radius all the way round with a router bit in my laminate trimmer.Used oak qaudrant for edge trim.Just put every thing together to see how it fitted. Just took some shots of progress so far.

That is coming along nicely. Very robust enclosure. What color / stain scheme are you planning on using?
