SB29RDCN-C000-4 Ring Dome Tweeter & SB13PFC25-08 Paper Cone Woofer
High frequency reproduction is anchored by the SB29RDCN-C000-4 1" Neo Magnet Ring Dome Tweeter. This flagship tweeter of the SB has the required sensitivity and power handling to hold its own with six midbass drivers. Additionally, its smooth extended response and low distortion truly qualify it as a world class tweeter.
From their recently introduced lower price/high performance PFC line, SB Acoustics hit one out of the park with the SB13PFC25-08 5" Paper Cone Woofer. This quickly became a go-to for the discerning builder, providing everything we have come to expect from SB in a truly budget friendly package.
Assembled Crossover
Madisound professionally assembled Uluwatu crossovers use high quality parts throughout. Each channel is mounted on a MatrixDouble inlaid copper circuit board. All parts are terminated with silver solder. The woofer section includes Sledgehammer SL 15 awg & Sidewinder 16 awg coils. The tweeter cap is a ClarityCap PX. All parts hold to the exact values of the design. This crossover board requires you to solder speaker wires to the designated points on the circuit board, as specified in the included hookup sheet.
Multiple capacitor upgrade options are available from the drop down menu above.
*Single Uluwatu Kits are available for 1/2 the price of a pair.*

Let's say you build a 2-way. Time align the drivers. Feeling good, right? But is it worth it? You build an MtM? Nice clean presentation. Strong mids, respectable low bass. And then you think, what if I had an MtMWW. Let's just add a few more drivers, right? Drivers are pretty cheap ... I mean, you're time is worth something too, right? So you add a few drivers and are feeling a little better. But are you? You're looking at a pile of scraps left over from those 2 sheets MDF. What more could you have done? You ported the speaker so you wouldn't have to bother with a curvilinear transmission line. The base is pretty good ... say 38hz, but did you know you didn't build state of the art. Curt gets another octave from his designs. You spent a ton on drivers but the system sensitivity is 86db. That doesn't matter, right? Or does it... What if you could double sound pressure for the same amplifier watt? Say goodbye to regrets and BUILD THIS ONE. As the last reviewer indicated, this speaker is so crisp and clear and loud - it absolutely shames bad recordings, mediocre production, and compression. The drivers are so accurate and fast and coherent that big music sounds big. Jazz especially, female vocals, music with texture -- what for an audiophile is... music. They sound unbelievable and I don't feel like there was a square inch or missing driver or smart enclosure design or anything affordable, left on the table. Bravo Curt and Adam. I'm a bit shocked more of these don't go out the door and maybe because they're so affordable. Before Madisound jacks the price, get yours.
