Hi! I want to build a DJ desk for my living room, and I want to integrate 2 full range speakers in the desk (left and right, at 45 degree, tilted at 45 degree towards the top: almost studio vibe) plus 1 subwoofer under the desk. So when you move the desk the whole system is moving with it.
I couldn’t find projects like this online (maybe I haven’t searched enough) so I was wondering if it does make sense at all or not.
If it does, I wanted to ask: which kind of full range driver would you recommend for monitoring? I wanted something that would reach at least 90hz, with a SPL at 1m of minimum 88db and I found a coaxial speaker from Dayton that would work good, but I never tried it.
https://www.soundimports.eu/en/dayton-audio-cx120-8.html
These could reach 80hz when ported. But I ask myself. Does it make sense to make them ported if I use a subwoofer?
I would pair them with this subwoofer:
https://www.soundimports.eu/en/grs-8sw-4he-8.html
Is it good to go for these coaxial speaker? Should I go vented or not for the full range speakers? Would you recommend something else instead?
I would like to avoid building crossovers, and go one way.
I hope somebody can give me some ideas ❤️
Thank you in advance!

Hi, the tweeter inside the coaxial says "High pass filter required (not included)"
The woofer says -3dB at 5kHz.
Not a big problem but...
The crossover or whatever splits the signal or mixes (for 2.1 ) and performs high pass and low pass is therefore needed.
You can go away with satellites without high pass filter and just a cap for crossover (the tweeter) for a start.
Dunno what you're thinking about amplifiers...
I'd get two GRS subs so a future stereo full range speakers can be created (just another sub enclosure)!
Though there is a sensitivity mismatch: 85dB and 88.5dB
It's a sub and you pay for it, but it's a useless data if you use active cross+ power

A lot of confusion around those. Given the transparency (lack of) specs and driver info i woulod not go near them.

Thanks for the fast reply.
I found these ones from the lii song: f-6S
https://www.lii-song.com/product/f-6s/
And the subwoofer from sunfire is a bit too expensive for my needs. I will probably build it myself and get a sub plate.
I didn’t know about song lii! It looks like they do great stuff!
So my question is. Since I will put a subwoofer, do I still need to build them ported or not? I hope it isn’t a silly question.
Bests! And thanks again ❤️

Thanks for clarifying. I checked the Markaudio and they look really beautiful and perfect for my needs. Since I would make a sub, does it make sense to go vented with the Markaudio?
Thanks a lot Dave,

Thanks ! I didn’t notice a crossover was required! Definitely not the way I wanted.
Dave just recommended me the Markaudio, which are simple to install and I found a building plan as well.
Do you really think one sub is not enough? I will attach my idea.
I’m really bad in drawing. I will do an auto as sketch soon!
Thanks a lot ❤️

I'd make the desk an usual one, steel frame, preferably with bends for closing itself, and the subwoofer unit under it.
First you have to get the amplifiers so the power of the thingy is defined. Satellites follow. It's better to have 50 W amps and 120 W speakers for long thermal overload, so a 250 W or more for the subwoofer, I guess... I never played with that power.
So separate everything, just in case ..
If nearfield party is required, sort of cocktail party, a bandpass sub with two holes for the ice!?!

Under your desk yes, as long as it is decent.
In this situation you want to ues a “REL” configuration. Let the FR/Satelitterech down as low as it goes (ideally<100 Hz) and then dial in the wooferlevel,XO, and phaseto suit the top. This just requies a sutiabke plate amp with builkt-in XO,
PH7HD in the optimum box should only require help below 65-70 Hz. Room plays a significant role in getitng them dialed in.

Porting not really needed for full range / wideband speaker
sub will take over from there.
ideally crossover is 100 Hz or below.
but many systems take it up to 150 Hz
having used numerous " computer speakers" and a few
sound bars over the years for my desk top listening.
usually dont downfire the sub.
I face it straight up or to the side.
and the higher crossover usually works/ sounds better.

I have a setup
The Jordans are obsolete, replaced by the Eikona, but if I were starting over, I would go with Alpair.
The coherence of a full-ranger makes it ideal for near-field listening, and having the speakers close to your ears means they sound loud without needing a lot of juice. I frequently play this system at 85dB at my listening position, which means they are likely using one watt or less. (My amp is 50wpc).
I chose the Dayton 8" sub because the price is great and it is very compact, which I needed, but mostly because it has a second-order low pass filter. The monitor cabinets are sealed, which means they have a natural 12dB/octave rolloff. The second-order low pass on the Dayton subs sums with the monitors to provide a perfect 2nd-Order Butterworth filter.
A second SUB-800, or one SUB-1000 would probably be better, but I just don't have the room. Most plate amps have a 24dB crossover, which does not sound right with sealed mains. If you build your own sub as you mentioned, I would suggest a miniDSP crossover, which would allow you to choose your crossover point and 12dB slope, and even implement REW corrections.
I have a desktop setup similar to what is being discussed here; Jordan JX92S full-range drivers in 7L curved Parts Express boxes and Dayton SB-800 subwoofer. It sounds amazing, and that is not just my opinion, but shared by my snooty audiophile friends. 😀

Let me add to this. Multiple woofers are used to tame the room, nearfield the room plays MUCH less role.

I agree, the drawing illustrates the plan sufficiently, though I have to wonder whether the rock wool will have any effect.
Some peope (@Cal Weldon) like rock wool. Dyna A25 was almost wall-to-wall with it.
I prefer using UltraTouch & Accoustastuff.

I can see that rock wool or similar would be effective inside the sub enclosure, but the drawing shows an enclosure wall between the sub cabinet and the rock wool. If the wool is not in the sub cabinet, I don't see it having any effect.

My drawing? There are sufficent holes (30-40%) so that the woofer does not see them in the airspace. They create a rigid structure that pushes (potential resonances high enuff in frequency to not be an issue.
dave
Thanks! I tried my best 😂❤️ thanks for believing in my sketches 🙂
Same! I wanted to isolate the sub from the table. but maybe hanging the sub to these two enclosures filled with rock wool, left and right is not the best. It will do something for sure.
So thanks for this insight! I will try doing some experiments and see what would be the best option to isolate the sub. Maybe hanging it to these two enclosures so that the enclosures don’t touch directly?
This is a great help!! I think when I will DJ I will keep the sub at a very low volume, acting as a crossover for the fullrange around 100hz.
I think I will try keeping the budget as low as possible and then in the future see if there is place for improvement.
I keep you updated with my strange project 🙂 it will take some time. But thanks to you I know where and how to start 😁❤️

Cioz,
Please note that the frequency response of wide-band (aka full-range) drivers often contain peaks in certain frequency bands - since you mentioned that this would be a "monitoring system", better check out the FR curves of the drivers you plan to select and see if this will meet your requirements.
