Description

LX521 Flat Pack Cabinets – Pair 

The price shown is for a stereo pair.

The LX521 is a full scale DIY speaker design from Siegfried Linkwitz of Linkwitz Lab. Also see the more compact LXmini Speaker Kit.

Madisound is excited to offer easy to assemble flat pack cabinets for this speaker kit. We also offer the Seas LX521 drivers, LX521.4 Linkwitz Lab ASP.4 Analog Signal Processor, and the miniDSP 4x10 HD Digital Signal Processor for this kit. 

The LX521 cabinets are locally cut by CNC machine from high quality 13 layer .72” Baltic Birch. The tweeter sub-baffles are hand cut from 1/8” Baltic Birch. We have been doing successful business with this local woodworking company for over 10 years, and they consistently provide top-notch work (see other products). The cabinets are shipped from Madisound to you flat packed, each enclosure in its own protective shipping container.

The top baffle, v-frame woofer enclosure, and woofer bridge are all cut with tongue and groove joints for easy and accurate assembly. To ensure the most rigid enclosure possible, there are several strategically placed screw hole recesses. None of the screws are visible when facing the speaker. We provide the appropriate screws for enclosure assembly and driver mounting.

      High Quality Cuts
      The flat pack was well thought out and with a little bit of pre-planning and reading the Linkwitz documentation, I was able to put these speakers together correctly the first time. They have carefully hidden all fasteners as much as possible and the cuts were well done. Much better than if I had done it myself. Initially, I was hesitant to pay in excess of $600 for pre-cut wood. But having it done right the first time made it worth the cost. I recommend this flat pack if you are not into woodworking (I am not).
