seas l18

rv1890 · 29th January 2008, 07:08 PM

Hey all. Its been quite awhile since Ive been on this site. Im looking build my next set of loudspeakers. I have a pair of the Seas l18 metals. I was wondering what projects r out there that utilize these speakers. So far Ive only found the ones on Zaphs site using the l18/27tbfcg. Im searching ans searching but only seem to find Zaphs project. Any other suggestions?? I would hate to have buy other speakers just to follow another design. I would rather stick to something that is tried and true. Thanks.

Zaph's design is tried and true. Is there some aspect of it that you don't like?

rv1890,
there are only two designs that I know of. For the newer version of the L18 there is Zaph's design and for the older version of the L18 there is this: http://www.humblehomemadehifi.com/DD8-MkII.html

Keep in mind that the two different versions of the L18 are NOT interchangeable.

I know they are tried and true, and they are probably what I will build again, but I just wanted to know if there are other options out there.

What tweeters are you planning to use with the L18s? I am assuming you are not using the 27TBFC/G.

If you choose another tweeter, you'll want to crossover to the L18 no higher than 2KHz. I recall Zaph saying in hindsight he would lower the L18/27TBFCG Fc to approx 1.7KHz. This is to further reduce the harmonic distortion contributed by the L18 - caused by the 7KHz breakup node.

Candidate tweeters (that can handle the excursion requirements of the lower xo point) are the Seas 27TDFC and Dayton RS28... and probably others in that price range.

David.
