Need speakers that can rock with just one watt? You found da place.

RE: Alternatives to horns

if you're game to diy and experiment

a 6" piece of pvc makes an excellent sounding waveguide to augment woofers
and one Karlson builder uses the slotted open end waveguide to augment Fostex FE206EN in his custom Karlson-coupler.

a long-distance friend is testing a K-coupler/tapped transline designed by Greg B. over at Gregg Baker's Karlson Loudspeaker forum.

Horns are cool but they're not the only thing in this world.

Fostex FE206EN in a custom little Karlson coupler - not much bass but
very good midrange and highs (considering its that driver)

Beta 10cx with APT50 in an old diy Karlson 12 copy - hits a
good bass drum with my AlephJ clone

ugly painted K12 copy loaded with P-Audio 12CXA

3-K-couplers: A k12 with cast frame 800z magnet Eminence, A X15 copy
with Audio Nirvana stamped frame Super10, and a 1954 Karlsonette
loaded with Tangband W8-1772 all sitting in front of my Klipschorn

An EV15B in a 29"x20"x15" K-coupler built by KK Audio for bass guitar

The KK Audio Karlson-coupler topped with a Transylvania Power Company
slotted tube waveguide - its extremely natural sounding in the highs
plus this is a very good little bass/midbass coupler


Scrap 5" k-coupler with a $10 Dayton 5"

K12 with Beta 12LTA - Beta 12LTA lacks motor but over at Diyaudio,
those guys are impressed :^)

Ancient dried up University 122 speaker - Fs >100Hz, Qts <1.4
damn thing sounds great on Jimmy Roselli

Closeup of FE206EN in the 1954 little Karslsonette - its better
than my Klipschorn for coherency with the better percussion CDs
plus rocks oh Johnny Cash
