Hi guys!
I need your precious support, as always!😉
I want to build a pair of wooden cabinet, about 20 liters, without back cover.
I think this is a kind of "open baffle" system.
Well, I would to add also a pair of tweeters, in order to increase the output power of the whole loudspeaker.
Infact I must connect these speakers to an amplififier of 12 watt RMS into 8 ohm (and 18 watt peak power into 8 ohm).
The Monacor SP-205/8 has just 8 watt RMS so I must increase a little bit the output power by adding a tweeter.
Please, could you reccomend me some good tweeter for this project?
I don't pretend any absolutely audiophile performances from this project, but a simple decent sound will be enough for me.
Here're the specs of the Monacor SP-205/8 if that could help you:
Monacor Breitbandlautsprecher SPM-200X/4
Please, my friends don't leave me alone...I need your support to bring to completion this project...so, I beg you, help me!

Thank you very much in advance for the patience and for your kindness!
Best regards!😉

Are you building the Cheap Trick 269?
You don't need to increase the power handling of the speaker with a tweeter unless you want to add them for other reasons. A 12W RMS amplifier will drive a 8W RMS speaker just fine. Even with 1W power from amplifier you will get 94dB of output from this driver!

Hi Mayuri!
Thank you very much for your reply!...yes, the project should be the Cheap Trick 269, but with a smaller cabinet size.
Don't worry, I don't want to increase the S.P.L.
I'd like to add a sort of "super-tweeter"...it's my desire😉
Please, help me!...I don't have any idea about the tweeter to add.
Make me happy with your precious advice! I need your support, guys!

Alright. I think the easiest possible mod would be to get a tweeter with sensitivity between 90-95db/W and 8ohm resistance, add a capacitor around 2-3uF area in it's signal wire and call it a day 🙂 Place as close to the FR driver as possible. If you want to attentuate the high end of the FR as well, place a coil around 0,15mH in its signal wire. For example Audax TW01 could work very well, and would not break your bank with costs 🙂
Hi Mayuri!
Your is a nice advice! thank you very much, you make me happy😉!
Just a last question, dear Mayuri: forgive me, but I don't speak english very well, so I can't understand the following phrase in your message:
" If you want to attentuate the high end of the FR as well..."
I apologize for my ignorance...but I don't know what the expression "to attenuate the high end of..."means in this case.
Perhaps you wanted to say:" to attenuate the highest frequency of the FR".
I repeat, forgive me, Mayuri, I don't want to abuse of your patience.
Thank you so much!

No worries mate 😀
I mean the if you want to roll out the highest frequencies of the full range driver, then add a coil in series.

Hi !
This is just my opinion based on my recent experience with the 205/8:
You will can more easily avoid a tweeter than a woofer or a subwoofer. Even in the ct269, you will get almost nothing below 100 hz. Your loudspeaker will lack bass drastically. If you want to add a tweeter, i suggest a piezo with a serial capacitor to adjust its level (0.5 ~~ 2uF) that you can adjust value by listening.

Hi Killmister!
Thank you very much for your precious report!|
So don't you like the Monacor SP-205?
Do you retain the bass lack is too annoying to your ears?
Thank you!

Hi !
Sp205/8 is not a bad driver at all and except the bass, it gives a honorably balanced sound with a very good medium. Its resonant frequency is too high ,about 125 hz measured.It needs bass support . The notes with a frequency below 100 hz will be very attenuated or absent if no bass support.
