## Description

DIY3.1A speaker: high-fidelity system – This kit uses many of the same components that are in our much more expensive high-end systems.

Review: Really enjoyed the process - A very complete kit (besides Xover mod). Instructions are rudimentary, but believe it or not, a good thing. Makes you research everything, while learning a lot a long the way, from glue, to capacitors, to finishes. Don't rush the build, it's a hobby. I chose the #5 mod. My goal was to keep the kit inexpensive. Researched real veneers, decided on vinyl, don't regret. I could use the vinyl with the kit, it would work but boring. Supplied vinyl is meh. They sound great, detailed, but on the colder side for my liking as is. Some EQ from my amp (room correction) improves, warmer. My main listening speakers now. Happy. Building anything is not just about the final product... it's the journey. A rewarding project, will do something again.
Review: These HIVI-Swans 3.1a's deliver the sonic goods! - My 3rd diy speaker build (after 2 from Part Express) and the HIVI-Swan 3.1a kit was a fun one to put together. After extensive research on ASR and Audiokarma.org plus the mostly 5 star reviews from the majority of the comments I was sold on ordering a set for myself. These speakers are dynamic and superior to any bookshelf I've owned or built, including the Klipsch rp 600m's they're replacing. Powered thru a recapped Sansui 5000a or updated Fisher TA 800 tube receiver (Soulpeak P2 switch lets me choose my weapon), these 3-ways are sonically stunning and pretty darn cool looking. Went with the Sehlin Perfection Mod 4 crossover to elegantly tame the highs. The Sansui is 55wpc and with the new main caps I can barely get the volume past 4 outta 10 in the 20'x 14' living room. The HIVI's are paired with an Infinity PS-8 sub. Did not care for the goofy midrange overlap on the tweeter so I recessed the mid and cut a radius in tweeter flange with a hacksaw for a flush fit. (see photos). I added a thin 10mil red oak veneer and hand-cut the radius openings, stained and finished with Danish oil, 2 coats ea. As many have mentioned, the instructions are limiting but adequate and with an abundance of online info and YouTube videos, it was not technically challenging. The kit was packed well and arrived a day early. I feel for what you spend and what you get, including an extra $35+/- on the Perfection Mod 4 parts from PE, for just over $400 you are getting a speaker worth 2x+ that; so an incredible value IMHO. Prior to final connections I bench-tested with 1 1/2" supplied dampening foam in one and the 1/2" PE Sonic Barrier in the other (adhesive side covered for easy removal). The supplied foam provided a superior overall sound so I stuck with that. Each day they seem to break in a little more and sound clear and dynamic, even in the bookshelf setup which may not be ideal since they are 3'"+ off the wall. My 70+ ears are still functioning pretty well (despite what my wife says) but these speakers produce sweet airiness of the mid/high ends while bass clarity and punch excels on all volume levels IMHO. A great investment for those who like the diy audio projects with a big payoff.

### ⭐⭐⭐⭐⭐ Great value* pair of speakers
*by D***N on 25 March 2026*

Treble is indeed HOT. But with a proper EQ or just follow the Sehlin collection of mods, these really punch WAY above their price point. These produce an incredible amount of bass; mid is clear, just what you expect from an soft dome driver; the AMT tweeters can bleed your ears if not tamed correctly. The imaging left some to be desired but all round accurate enough (for my ears). Soundstage is decent, not mind blowing, but these aren't surround system so that is expected. My pair use the Sehlin mod 5, which agressively lowers the treble response. In the end, I did have to EQ the Bass and trebble a little bit to match my taste. All in all, these are amazing for the price. Looking forward to building them again given a chance.
