Rediscovery II Drivers

Revelator 18W/4531G-00 7" Revelator mid/woofer. Non-resonant cone and dust cap structure, dynamic linear suspension, SD-1 magnet system, “Grasshopper" cast chassis with maximized air flow and resonance terminating mounting system. Less resonance in all structures; lower compression and higher linearity; faster termination of excess energy; and higher sound pressure capability. This 7" slit paper cone driver is widely considered one of the best mid/bass units in existence. Made in Denmark.

Discovery D2608/9130 1" Textile Dome HDS Tweeter. The Discovery tweeter uses a very light, low mass soft dome with high internal damping, and a highly-optimized, low-compression magnet system, which was designed especially for the low mass dome. The result is a driver with both good sensitivity and an impressive range into the lower frequencies. The low mass dome, coupled with a fully vented motor system, provides non-compressed sound reproduction over the entire frequency response. This combination allows the Discovery tweeter to be used in systems with lower cross-over points than recommended for most normal tweeters, making this product a powerful tool for any acoustic designer in the process of tuning a system.

Cabinet Plans Download Rediscovery II Cabinet Drawing

The ReDiscovery II is based on a 0.8 cubic foot vented enclosure, external dimensions [18"H x 9"W x 12.75"D] and tuned with a single 2" diameter x 4" length vent (4.5"length if using internal flare).

Crossover Design

PLEASE NOTE: Assembled ReDiscovery II crossovers are quite large and are built on two boards per channel. The high-pass is on the MATRIX board measuring 5.6" x 5.625". The low-pass will be on a 103B, 9.55" x 4.05". This will require mounting one board on the cabinet base (floor) and the other on the side-wall. Please make sure you allow for this when building your enclosure. As always you can run the crossovers externally if you prefer.

ReDiscovery II Assembled Crossover (pictured with ESA caps)

As noted above, crossovers will be built on two boards per channel using premium Goertz brand 16awg copper foil inductor on woofer and Clarity CSA cap in series on tweeter. Mundorf resistors in high-pass section.

Frequency Response- individual

This graph shows the output in SPL across the frequency range. The left-most line is the woofer and the right designates tweeter. The crossover "point" is at about 2 kHz.

Frequency Response- summed

This graph shows the summed frequency response. Nominal output is in the mid- 80's dB region. Not super-efficient, but not too low either.

This graph shows the system impedance. Mostly 4-6 ohms across the midband. Should be a friendly impedance load to most amplifiers.

Rediscovery II Accessories Package

This accessories package is available for convenience as part of the kit, or feel free to purchase any of these items separately. As with all our kits, the discount only applies to this accessories package, not individual parts purchases.

20' of Supra Classic 1.6 speaker cable for internal wiring – 15awg Tin-plated Oxygen-free Copper from Sweden.
One tube of Household Goop for adhering ports and insulation.
Quick Connects x 16 for easier connection of drive units and terminal cups.
Mounting Hardware: 22 of the 8x1 Socket Head Screws and 8 of the 6x3/4 Oval Head Screws for TD-CUPS.
Damping Materials are one of our acoustic foam sheets (ours are 27" x 42" and 5/8" thick) and 1 lbs of Acousta-Stuf complex fiber fill.
2FLARE 2" Precision Flared Ports: two per kit, for vented box option- less the outer flare- which is too large to fit on the front baffle. You will receive the center tube, connector ring, and internal flare (we have found flared ports tend to provide better air flow than straight PVC).
TD-CUP Terminal Cups: two per kit. High quality gold plated brass binding posts. Accepts banana plugs, spades or raw wire, and are bi-wire/bi-amp ready.

Basic Assembly Instructions

Using the drivers and desired terminal cup or binding posts as templates, mark the enclosure for pilot holes.
Drill pilot holes.
Cut internal wire to appropriate lengths. For this design you will want approximately 12" for the tweeter input, 12" for the woofer input; 20" for tweeter, 22" for woofer- per speaker. Adjust according to the cable type you are using.
Solder wires to crossover, observing polarity.
Install crossover inside cabinet. We recommend a double stick tape to adhere to the cabinet base.
Solder input leads to terminal cup, observing polarity.
Install terminal cup.
Cut and install desired insulation materials. Typically you would cut a slit in the foam, then pull the drivers' lead wires out through their respective driver holes.
Separate and fluff-out fill material such as Acousta-Stuf then place in cabinet, dispersing evenly throughout the main cavity.
Apply gasketing tape material to cutout holes if desired.
Solder wires to drivers, observing polarity.
Align drivers with pilot holes and secure with wood screws or desired fasteners. Tighten slowly and evenly.
Double-check polarity. If woofer polarity is incorrect, the loudspeaker will typically have weak or poor bass response. If tweeter polarity is wrong, the mid-basses may have a dip in response in the midrange and sound odd.

Yup, 5 years in and they never fail to impress

I used this kit for speakers on either side of a 50's style console I built out of walnut. The cabs are solid walnut to match. They do seem to like a fair bit of power. I put them on a NAD M10 V2 streaming amp and BOOM!

Danish 2 way

Reviewed by HappySounds on 01/28/2022

I purchased the ReDiscovery II kit about 5 years ago. As time has gone by and gear has come and gone in my system I have said to myself many times, "man I need to write a review on this." I will add pictures if I can figure out how? So I built the cabinet with Baltic Birch Ply, 3/4" and 1" for the baffle. Basically just to kit specifications. I eventually added rolled felt to the inside noncurved section of the port ("stealth port" from troel's Gravesen site).
I still remember the first time I played a track on these and admiring how the tweeter and upper midrange was so effortless. At the time I was going back and forth with my Magnepan .7s. So what a compliment!! The rediscovery II is so airy and detailed. Large sounding. It is a bigger cabinet but it does sound so much fuller and larger than my Kef and B&W standmount speakers. Like any great speaker it changes with the gear. I have used my Rogue Sphinx, Yamaha integrated, Emotive mono. They were all fine but I am just loving my current set up, Van Alstine Transcendence pre (National/Matsushita tubes from Upscale Audio) and Parasound Halo A23+ amp. The sound is so rich yet dynamic. Detailed yet I can play lesser recordings and still enjoy the music. This sound is next level sort of sound. For me it beats the snot out of any common or well known speaker manufacturer unless you are talking about Wilson or some botique Danish speaker costing $15,000. Unlike my Magnepan .7s these speakers can party or give you that bass slam from pop or electronica. After swapping the tubes on my pre (National/Matsushita) the organic quality and textures and tones just ooze through this speaker. I guess I have decided that when I get bored and want a new set of speakers I won't even bother with my local HiFi shop and will just go with a Danish kit (SB Acoustics, ScanSpeak..) or Seas from Madisound. I wish Madisound kept just a couple Baltic Birch Flatpacks on hand for a few key kits. Just to entice more people. Thanks Madisound for allowing me to have super high end audio that I can afford.

I have several speakers from madisound 2way kits version.
This speaker produces more beautiful sounds than other more expensive ones.
Of couse they depends on enclosures and also what kind of music I play.

The kit was purchased to be assemblled into quailty monitors for a Yamaha keyboard. As such it performs admirably. The accessory kit provided the foam that was glued on most of the inside of the box, and the box was sealed so that all parts cpuld be removed from the woofer opening. As can be seen from the photographs (to be supplied), the drivers were mounted on the front surface of the boxes to get a good seal. Also, the crossovers were mounted to the foam in case their removal or repair were necessary. The boxes were made to inside dimensions exactly as per the supplied diagram of one inch MDF making them about 25 or so pounds each. The foam was glued on with a hotmelt glue gun which made the job go quicker as drying time is not too long. The tweeter crossover was mounted on the side wall since the heavier woofer crossover took up all the space on the box floor. The tweeter crossover was placed so that it's induction coil was as far away from the woofer crossover inductors to minimize crosstalk. Per the above the system performs well compared to others in its class.
