Hi, i`m thinking of building my own tv bench/furniture with built in speakers.
Inspired by The lemus home classic series.
Yes, i could just buy the lemus one and probably be satisfied, but I want to try a DIY project, maybe get better sound and save some money aswell.
Never built speakers before, so i am sure it`s gonna be a challenge, but i am ready to dive into the DIY madness.
I have sketched up the furniture, and the speaker "boxes" will be about 40cm wide, 35cm deep and 26cm high, thats around 36l in volume. The space between the 2 boxes are around 80cm. So the furniture will be in total about 160cm wide. Thinking of using 19mm(25mm on the front baffle) MDF as a material.
The speakers will be driven by a Harman Kardon Citation Amp (2x125w 8ohm).
First question: what drivers to choose? Thinking of a 2 way system. 6.5" or 8" woofer and a tweeter.
Since i cant move the speakers around in the room i need something with a wide soundstage.
The seas factory is close by so i was thinking of using their elements, but im not locked to that brand by any means.
Budget for the woofers and tweeters are around 500-800euro.
I`m thinking about doing the boxes ported, but no idea if the enclosures are to small?
Next scary part is the making the crossovers, should i buy a pre-made one or try to make my own? 😱
I looking for some clean and fun sound for movies and music. Not planning on a subwoofer, but hopefully i can get some decent bass.
Anyone willing to push me in the right direction? 😛
Not a native english speaker, so sorry in advance 😀

Welcome to the forum!
I would look for a loudspeaker component kit which suits the volume of the speaker "box" in the furniture.
For example: Shopping for speaker component kits? - SoundImports
That way, you can be sure the crossovers are targeted to the drivers rather than simply being hit or miss.
Say where you are based so that we can recommend suppliers that are local to you.

That looks like a nice project with high WAF, as long as you're not going to put a turntable on it.. the vibrations from the speakers might be a problem.
Certainly, a well regarded and widely built DIY design is the way to go and there are many options for you from noted designers.
The only thing I'm not sure about is whether the width of your speaker enclosures will have implications for the amount of Baffle Step Compensation (BSC) which is designed into the selected project. For example, a typical 6" two way speaker might have a 22cm wide baffle, yours is 40cm; the design will have an crossover which gives, say, 3dB of BSC based on that 9" baffle width.
If your enclosures were, say 30cm wide, I'd think it wouldn't matter that much. Maybe select (on paper!) a design whose woofer fits your enclosure, then either ask the designer or post a question here about this issue?
I'm happy for someone to tell me that my assumptions on the BSC issue are incorrect.

PS to previous post: as an example, the SB20pfc woofer (8") is stated as having an F3 (i.e. 3dB down) of 45Hz in a box your size, with a 2" x 3.5" vent.
Maybe look at some 8" two way designs which feature a dome tweeter, such as Wolf's Zingers? Cabinet size differs from yours but you could ask him about whether it's a good idea?
And to Wolf, I apologise if this isn't an appropriate or feasible suggestion.
I'm suggesting a dome tweeter rather than a paper cone tweeter such as a Vifa TC-7, as dome tweeters tend to have better off-axis performance.

I`m located in Norway. Ye, a kit is probably the way to go to make sure the drivers and crossovers match.
One easy way to prototype the crossover is to take 2 channels of an amp, or 3 if 3 way, and drive the woofer (midrange) and tweeter separately. Graphic equalizers are all over ebay for $50-60, that can be your crossover first cut. Maybe 2 each if a 3 way design. When you have a contour you find pleasing or tests well, Then dive into buying the expensive coils and capacitors for the crossover. At 125 w/ch you won't need the expensive 15 ga coils. BTW I picked up another working 325 w/ch amp for $106 + freight this month, get out & look around. Dirty, bent mount ears, no front panel volume knobs, stupid Phoenix connectors in instead of RCA or 1/4 phone. .02% HD the QSC brochure says. That gets you 4 channels of driver current while you fiddle with passive crossovers for a year.
If you can do sims on your PC fine. If not David Weems Designing Building and Testing your own Speaker System was $10 and has formulas you calculate with a $4 calculator or calculator function of the PC.

Not gonna have a turntable in it, probably just my xbox, nes mini and the switch docking station.
Yes, need a tweeter with good off-axis performance, a dome with a waveguide or something.
Not familiar with Wolf, but i`ll check it out 🙂 Was hoping to get around a 40-45hz tuning.
Sounds like the right way to do the crossovers if i`m going that route 🙂
The reason i`m going with the Harman Kardon one is that it`s small, good power and has eARC so i just need one hdmi cabel and can control the volume with the TV remote. It has a pre out too, so if i one day decide to add i sub i can do that also.
As a new member, pk82, you may not be aware of the forum guideline which asks that you don't quote the entire post above yours.
Doing so clutters up the thread unnecessarily and makes it difficult to navigate.

Looks like a fun project. I've built a few dozen stereo cabinets and 8"+tweeter is a good combo. One I designed used 3X Focal car speakers. I used the coax speakers in that project for best imaging and dialog, as it was meant for both music and movies. Having a dedicated center channel is worthwhile for movies. That one also used a 12" subwoofer crossed circa 90Hz. Plenty of thump.
I agree with the other in the thread who say find a kit that is made for the box volume you want. The project is big enough without having to worry about every detail of speaker design.

Ye, sorry, I saw that afterwards, but I don`t have an edit button on my posts other than the main one 😕
You should for 30 minutes. That's the edit time limit, except for if you made the first post, then you can edit that forever.
