if the sound is sour, it could be the break up peak of the SLS315. Play with the tweeter will not solve the problem. You can try my crossover version, a complete suppression of this peak : post #128

here is a question....

i wonder if its possible to make a pair of those based on 8" woofers but also for very low power ( 5-10W of listening ) eventhough conected to a 80w amplifier

the problem is that these are supposed to be "very" near field located in my shop just in front of me on my working bench

distance be tween them might be no more than 2.5 meters and they can be also placed no more than 20 cm from the wall ...

do you think worth trying ?

Dipole bass is said to suffer near a wall. You might need the amplifier power anyway since the dipole roloff reqires lots of EQ boost.
Also if the rear wall is so close it might sound weird.

The EQ us done with the passive crossover. Making it smaller and close to the wall, I don't know how well that would work. The baffles are quick and easy to make, tho, it's the crossover work that takes time.

Hi Sakis , You can put 'em in an H-frame ...it will become halfway between dipole and aperiodic
If you already have the original baffle of the 8" woofers , just cut a square around the hole .
I did it in a 3 way speaker with cheap speakers ( 4 Ohm ) I had around and it works good (the mid is in a cube box , tweeter outside ,on top ) .

The OB project does not seem complicated construction, and according to the responses also sounds good.

Not long ago I had VR4-JR, that sounds great but required very expensive amplification to produce high-quality sound. I decided to try to build something cheap and good that did not require expensive amplification.

So, waiting for more information on new models, especially for floor standing OB version.

The floor standing model is the H.E. (High Efficiency). It uses an 8" fullrange and an 18" woofer. Not a small speaker. The 12" version will remain a stand mount speaker.

Besides efficiency, what differences in planning and sound of the two models?

And what about Manzanita BFTB?

Hello Simon

Thank you for your question. Its' been along time since Pano and I worked on the orginal Manzinita with the 27 TDFC tweeter. Could you tell me your current crossover configuration? Want to make sure I know where you are before trying to get you where you want to be.

John
