The C-Sharp powered bookshelf speaker kit makes it easy to build your own self-contained stereo system. This compact speaker pair provides extremely flat response with much more low end than you would expect from a speaker this small. In addition, the C-Sharp's controlled dispersion delivers pinpoint imaging with a surprisingly wide soundstage. The built-in Lepai LP40PA plate amplifier makes the C-Sharp a true stand alone system allowing you to easily connect through Bluetooth or line-in to play audio directly from any phone, tablet, computer, or TV.
Dayton Audio's DSA135-8 5" Designer Series woofer is used for the midrange and low frequencies. With an aluminum cone and a powerful motor designed for low distortion, this woofer produces bass with authority while remaining smooth through the midrange frequencies. The high frequencies are handled by the ND25FW-4 1" soft dome tweeter, also from Dayton Audio. This waveguide-loaded tweeter controls high frequency dispersion for smooth off axis response and natural sound.
The Lepai LP40PA consists of two main parts, the plate amplifier and the control panel. Producing up to 2 x 20 watts RMS (2 x 40 watts peak) the LP40PA has enough power to drive the C-Sharp to impressive output levels for serious room filling sound. The 4-button control panel gives you the ability to select between Bluetooth and 3.5 mm inputs and adjust volume up and down. In addition, when in Bluetooth mode the control panel allows you to skip track forward and back, along with play and pause.
The solid MDF enclosure's 1/2" panels are all CNC milled to tight tolerances, ensuring easy construction. The surface mounted woofer is easy to install, while the flush mounted tweeter provides a sleek appearance. With all necessary cutouts for the drivers, ports, amp, control panel, and terminal cup this kit is extremely easy to assemble.

Très belle réalisation

[@pliedtka]

Pretty good for basic loudspeaker kit to start with 👍 One thing - where's the damping material to reduce internal resonances. I would make the front baffle min 3/4" (19mm) thick.

[@DonnyTerek]

Thanks! Damping material is not needed for these speakers. It would be included in the design if it were necessary. Good idea on the thicker front baffle. Would have used it if I had a few pieces of 19mm thick board.

[@pliedtka]

@@DonnyTerek Up to you to stuff it, but there are still reflection and standing waves which affect the midrange, although the port itself is a source of standing waves as well. For bass reflex I usually fill up enclosure behind the woofer leaving space around port, but these days I like passive rads - more flexibility in tuning, no lengthy ports with 90 deg elbows, no chuffing noises. The price is higher and depending on the passive rad cone material, suspension, it will leave some character. Still to me sounds cleaner in midbass application. For R&D and prototyping I use box with double baffle. The actual baffle is screwed to the front panel of the enclosure. The baffle is divided into tweeter and bass section, so if I want to try different drivers, but their diameter is different or I want to change tweeter position, I replace the whole panel. Saves money on material and space.

[@ronaldcaraway8184]

I built two passive sub cabinets with two 18 inch sub woofers each for my sound system. The guys at Parts Express were great for helping me pick out the Dayton Audio 18's and the size to build the cabinets plus sub port size. They were 1,000 watts each and I pushed them with 2,000 watt amps each. They went down to 45Hz although I cut them at about 55 or 60. They brought on the thunder.

[@DonnyTerek]

Would love to have a pair of subs like these for myself if it weren't for the neighbours! I'm actually thinking of building an 18 inch ported sub myself. What amps did you use to power these?

[@ronaldcaraway8184]

[@cormacfarrell]

Love the video. Any particular reason you use MDF, which you then have to laminate, rather than a good quality plywood? is it about price, finish, acoustic properties? Thanks

[@DonnyTerek]

Thank you kindly. Personally I don't quite like working with plywood. MDF is much easier to work with and it is cheaper than high quality plywood. Adding to that MDF has better acoustic properties for speakers due to higher density.

[@neok1996]

I'm planning to make a sonos like speaker with logitech media server

[@EuBilt]

[@bobpuls]

Nice clean work . Next time try use acoustic foam inside to achieve better sound performance .... and maybe not MDF for body but some tipe of soft and dense wood, So you can have more crispy sound

[@samtibalfarst]

If you have already won, I will give you several types for improvement (personal experience). Put silicone under all the screws. On the inner walls, you stick foam board exactly 5 mm thick. from the Bass speaker, make a curved roll of foam to the bass reflex. Screw the front plate even more (not just glue). You will be surprised by the result…

You can easily and for cheap convert your own (or second hand)(or just any) bookshelf speakers to true stereo bluetooth. Get the awful sounding Roseland dual-split speaker take them apart. and link it to your speakers. for only 20 euro. The only thing you need to make is a new housing for the battery and the electronics. Pro's are 10 Meter apart, USB-C charge ports, SD card holder and line in (minijack) cons are: 10W and 4 to 8 ohms. But still good enough for an easy setup. I have converted my old Yamaha NS-BP 101 to bluetooth and it sound great! Loud enough for a small garden party.
