Hi Iggy,

if it needs to be Monacor, I can recommand this design here. It's very well documented, with lots of messurements, xover and all.

The designer will most certainly awnser questions via email in english.

or post your questions here in the Forum thread, I'll be there every once in a while and may help with translation if needed.

best, LC

Thanx for all the advices. This is my first (but not the last) DIY speaker. I wanted to start with something cheap and easy to build. Drivers are now here and playing in free air. Promising! I have Wh. Diamonds 8.3 and I hope (and think) that these speakers will sound a class above them. My next project will probably be something more demanding, like ProAc R. 2.5 clone, so there are Scan-Speaks. They can be bought in Croatia and I already asked for the price. Greetings to Split!

Could anyone tell me will I have a problem with baffle step compensation on this project http://jan-jaap.vegter.nu/bs.html. I don't know how to calculate it and how to fix it, if it is necessary. If someone could help me and tell me what to do I would be grateful. I don't know is it normal that, when I play them in free air, the drivers appears to be too ''bright'' (too much high frequencies). I would like to know what to do ASAP 'cause the boxes are nearly finished. Thank you very much.

Hi,

the crossover has very high attenuation of the tweeter, 6.8R in
series and 3.3 in parallel ~ 12dB of attenuation, if they are still
too bright with this I'm not sure whats going on.

With 95dB/W = 83dB/W which indicates the speaker has BSC.

/sreten.

Thank you. Maybe it will sound different when it's all done and in proper position. We'll see in a week or two. Thanx again.

Hi
I have sph165kep and vifa xt19td. They play very well
The Monacor sph165kep is a good speaker. In a small box they play very good - small box 20liter's :P

Look this:

About sph165cp:
this speaker don't get down like sph165kep. They play more "hard".

Sorry about my language

Hi,

Note that out of a box the bass/mid unit will have no bass at all.

Thanx, I'm aware of that. Anyway, soon they will be finished and we'll see the result. I'll keep you posted. I'll put some photos here after the job is done.
