CSS EL70

Thanks everyone. That's what I wanted to hear. I had read that the round ports didn't work as well for these drivers. It will cause me to change course a little but that's ok I think i'm going to try the markel70's. I've just got to hear them now. A little extra time in the shop is not necessarily a bad thing.

One last thing how much is a little juice? How hard could these be driven in these enclosures usefully? Are we talking 30wpc?

Well, the amps I use are usually a lot higher but that's just my choice. I would say these things start sounding good about 5 watts or so. Below that I seem to be missing some upper midrange. For many persons this is the ideal driver. For my ears I need a little top end sparkle.

I ask about the wattage because I've really become enamored with these "T" amps for this project and while I understand that headroom is a good thing I want enough power to fully utilize the capabilities of the speakers without worrying about a volume control mishap....

They will work fine, and they will like the EL70's 4 ohm.

Cal, missing upper mids! Adding a tweeter!

Personally I find that region robust. I can hear the baffle step in a small enclosure (what ever model Dave lent me). The lower mids were lacking, ~500hz. Not objectionable though

Cal is HF challenged, he likes his HOT.

I can't hear the upper stuff anyways. One of the reasons I like what I read about the EL70's is that they are fairly balanced and designed to address some of the inherent issues with fullrange speakers. BTW I'm working on a final desicion on which amp over at 41hz and thanks to them and you guys I'll be set. Dave from looking at those plans, when I actually get some wood cut I might have a question or two so thanks in advance...

The EL70 wont make you sad. They're wonderful for its price/size!

I have done a lot of listening. I am satisfied these are a good driver.
They will not replace larger speaker systems but I have no hesitation recommending this driver in this cabinet to anyone who is familiar with the limitations of a 4" FR driver.

They are a lot of fun to listen to. They put a smile on my face bigger than a 4" driver should.

Good work to all who had a hand in this project.

O.K. - There are 3 Mark Audio paper drivers within a few dollars of each other - el70, chp70 and alpair6p. I want to use some in a f.a.s.t. with el166s. Initially they'll be driven by a Yamaha htr (but not for movies) but that could be upgraded at a future date. I would think the alpairs would be the top choice but I'm looking for input from those that have heard all three since I haven't heard any of them. Thanks, Jim
