Crossover Schematic and Graphs

HDS Home Theater Kit Customer review:

 "I completed 5 speaker cabinets for the HDS kits that we ordered. I took the completed pair over to my HiFI guru friend and hooked then up to a wall full of high-end equipment. We were both amazed with the detailed sound, lifelike midrange and bright, authentic sound; furthermore the overall balance and imaging was fantastic."

"I wanted to complement the folks at Madisound for the HDS kits.  I’ve built ten so far, and had a chance to try them in different locations.   They really sound wonderful everywhere I tried them; they are extremely natural sounding.

As soon as I finished the first one and tested it with a signal generator, it was very obvious how even the response is, especially through the middle i.e. woofers crossing over into the tweeter."

The HDS kit is designed as an all-purpose loudspeaker suitable for two-channel stereo or for home theater systems; front, center channel, or surround applications. This MTM design utilizes two Peerless HDS 4" polypropylene woofers for clear midrange and well-resolved bass and the well-regarded XT25TG30-04 tweeter. Integrated phase plug on the XT25 tweeter allows for greater detail without distortion.

Each kit includes two woofers, one tweeter, and one crossover - professionally assembled with SW 16awg inductor on the woofers circuit and Solen CP Fastcap capacitor on the tweeter.

We are adding a Mundorf resistor at 2.2 ohms on the tweeter. This can be adjusted to taste, let us know if you want a different value. Please see the PDF datasheet for crossover schematic and frequency graphs.

The circuit board we use is our 64B, 5.5" x 3.75". Keep in mind this is too large to fit through the small woofer cutout hole, so you should plan to build the cabinets accordingly. We do not have cabinets for this kit at this time.

Sealed box of 8 liters (~0.28 cf) for the two drivers is recommended; F3 of ~ 100Hz. This allows a smooth rolloff and easy blending with your subwoofer lowpass. 8" Wide x 13" Tall x 5" Depth would give you just enough room to accommodate the two mid-basses on the 105mm truncated side and the tweeter but just barely. You can make it physically larger and subdivide it as well to tune the mid-basses if you wanted. Vented box is not recommended as the F3 becomes too low for good power handling.

Frequency response 80 Hz - 20 kHz +/- 3 dB. Impedance 4 ohms SPL ~90 dB.
