I've been into audio for along time mostly car stereo. But since I've grown up and got a house I'm now into home audio. My system right now is B&W cm5's fl and fr. B&W cm center. B&W ds3 surround. It makes a nice sounding ht and does good with music until I put it into 2 channel. I would like to build some dedicated 2 channel speakers. For the drivers I was looking at Alpair drivers. I just dont know the design aspect of the enclosure. Is there plans aready out there and what would you recommend for a nice pair of towers using these brand drivers. Looking for a tweeter, mid and maybe two bass drivers in each.

bigvag,

Some plans listed here on my site, there are some on Mark's site, and some big ones coming soon on the Wodendesign site.

None of these really need tweeters. Woofers, if needed, are usually best placed in a different place than the mains.

My personal favorites are the EL70eN, but then my Alpair7 & Alpair12 are still on the break-in bench.

What kind of budget do you have?

Don't really have a budget yet. Just feeling around right now. However I think I put this in the wrong forum I'm looking for more than one driver in the towers. I checked out your sight alot of usefull info on there.

If you are looking at the Alpair, it would be a REAL waste to add a tweeter. Firstly they have better top than many tweeters, and tou would be adding an XO to the mix. Remember XOs are evil.

You could well consider an Alpair 7 used as a mid-tweeter with a woofer crossed over below 400 Hz (less than 300 Hz prefered). This moves the XO into a range where it is MUCH less objectionable.

Have a look at Tysen and follow the links to the spin-offs to get a good idea of what i'm talking about.

What i'm looking for is a 2 channel set up that I don't need to add a sub to, or if i do a small one. You seem to know alot about the Alpair what would you build or have you built. I was looking at the Alpair 12 drivers.

planet10 · 15th February 2010, 12:46 AM

To extract low bass out of a FR usually means a BIG box. How big can you accomodate?

Alpair 12 either seems to like being in a BIG box or quite a small one.

And what kind of amplifier will you be using?

Note that samll & sub usually means it can't go all that low. Best bass in a room is usually accomplished with multiple woofers not placed in the same place as the mains.

I was looking to build the dual column air coupler found on marks page. Amp not sure yet this idea has come to me tonight so I still have alot of research to do. I read that the max rms is 50watts for the 12 so it must be a real efficient speaker. I use emotiva right now for my ht set up.

planet10 · 15th February 2010, 02:48 AM

I couldn't find a dual column air coupler for the A12 on Mark's site. But i know it, i drew the plans and they are on my site. It should be good into the 30s. And the A12 reaches well above 20k.

Ignore power ratings. In the context of home use they are all but meaningless.

This is what I was looking at. What are your recommendations for a amp.

planet10 · 15th February 2010, 03:58 AM

Something good (not much help eh

)

There is a thread here already on that subject.
