A view of my design. I don't have very good woodworking skills, but it's the sound that matters...

Click the image to open in full size.

SEAS L22 RNX/P, Morel EM1308, SEAS 22TAF/G
X/O 850hz LR4, 4Khz LR2
Box is closed and hands over to a Peerless 12" XXLS active sub around 60hz

Attached to these are...
Lin Karik CD player
Naim 72/250 amplifier
Naim NAC A5 cable

All very old but still capable

I've always really liked the look of a black cabinet with a natural wood face. I just wished there was a way you could have hidden those front screws a bit better! Other than that they look quite nice. How about telling us a bit about how they sound?

I'm listening to: Metaphora by Altered Laws

I was going to use M5 hex head bolts for the front, but I got lazy... Any better suggestions welcome

The mid has exceptionally clean sounding pianos and acoustic guitars. Bags of detail but with smooth vocals and strings. The tweeter is a beauty - very natural sounding with no hint of fizz, tizz, metallic sounds or anything else - they disappear.

Interestingly I've seen another design using the similar MDM55 and 22TAF/G. That uses a LR4 at 4k. I tried that. The sound had some merits but didn't gel like the LR2 does.

I'd say the bass units are pretty good but I have room problems in the bass. Regardless of what speakers I have, or where they are in the room, there's a massive narrow dip at 60hz with a little lightness above and below. On the other hand 30hz is very strong. Other than moving house I don't see a cure

Well from your description of the sound it seems like you hit a combination that works just right for your room, equipment and ears! I've seen people spend a lot more $$$$$ and not be as happy with the sound of their system as you seem to be! Sounds like a sonic marriage made in heaven. I'm very happy for you. Keep enjoying those speakers. Oh yeah one last thing before I go... what type of music do you listen to and at approximately what SPLs do you usually listen at?

I'm listening to: Jump In The Water by Jump In The Water

Baniels in post 1970 with reference to the pic showing the spikes ...
Could you please tell us more about the shape of the supports holding the spikes and the material from which it is made? Wonderful work BTW. A pleasure to view. Thanks. -Edward

Default Ordinary 2 way DIY box

Hi everybody,

this 2 way classic speaker was built by a good friend of mine
for his friend and my job was the engineering part. Artificial
leather glued on mdf, side panels painted with primer and paint
from spray can.

Vb= 18 litres
Fb= 36 Hz
Sensitivity:83 dB/2,83 V/1m
XO frequency: 2,7 kHz
Filter: LR4 acoustic
Bassmid: Peerless 830 874 PPB
Tweeter: Scan Speak D2606 920 000

We were both stunned by the amount and quality of bass output
from such an ordinary speaker unit. Voiced to sound transparent.

Cheers!

Lojzek, the efficiency is low but the speakers look very good.
