EOI FH: DIY Speaker Building


Recommended Posts

Hi Guys,

 

Im considering to help others to build DIY speakers. I dont have much talent on finishing other than some shellac and oil finish though. So dont expect wilson/sonus faber level of finishing :D

 

So here is what i have now :

 

1. Makita Circ Saw with multiple guides ( 2 KREG and 1 Homemade )

2. Makita RT0700CX Router with Jasper JIG

3. Compressor (Nail gun, stapler and possible sprayer if needed)

4. DATS (to measure impedance, phase and driver parameters)

5. Omnimic v2 (to measure and simulate passive XO)

6. Behringer ECM8000 calibrated by Cross Spectrum Labs (almost forgot this one :D)

 

I usually order my timber pre cut from supplier (birch ply from bruynzeel), and do fine adjustment upon building. 

 

Im not sure if this attract anyone, but im taking this opportunity to learn more about speaker building (or just say fine tuning with what i have learnt so far :D )

 

My previous project was (not all in Aussie ) :

1. alpair5 TL

2. Alpair10 FR in Pensil

3. Jordan JX92S in ML-TL designed collaborated by Greg Monfort and Jim Griffin.

4. OB with Beyma 12CX and dual 15" by Eminence Beta and Alpha (active in 600mm baffle width)

5. Alpair 10 Bass wide and Alpair 5 in BR 

6. Satori, RAAL and Kappalite 3way

7. Exodus Anarchy Tapped Horn (built 4 of these)

8. SB17 and SB29 2way series XO

9. SB15 and SB29 in MTM series XO (2.5way)

 

Im interested to help in the following project :

 

1. any project involving SB Acoustics drivers (as they have a very good price vs performance)

2. Econowave style (Large woofers with CD waveguides)

3. Line Arrays (as i have few prototype but not yet finished it)

4. PushPull SUB / Dual Opposed SUB

5. Bill Fitzmaurice's Horn Sub

6. Anything with Tapped Horn.

7. Active OB (could be H-frame, U-frame or even plain OB), i consider active, since we will need to deal with EQ and compensation, which is almost impossible to do  with passive xo without extensive trial and error.

 

The list above is something that i like to venture on and to get to know more about different types of speakers, but overall im open to experiement or not, if its just a kit.

 

Well PM me if you are interested :)

 

cheers

henry

i have the following equipments :

 

1. PASS FirstWatt F5 (25w)

2. ROTEL RMB 1075 (5ch)

3. Ncore NC400

4. Ncore NC1200

5. AudioGD Master7, Master5, Preamp C37, NFB12

6. PopPulse DAC, PCM1796

7. CEC TL51XR (coming soon :D)

8. Connex CxD400 (400w modules)

9. Connex IRS2092 scalable (150w modules)

10. Emotiva UMC-200 Processor

11. EL34 tubeamp (which need some repair as it has some problem with the Attenuator giving exercise to the woofer, wild excursion)

 

cheers

hi paul,

its pretty much my main hobby and interest, and im keen to explore more, but ive invested more than $10k for diy alone.

im still young and this year i have plenty of time, where i think i can tackle 2-3 projects in 1month :D

Hi guys,

 

just to give this thread a bit of direction, after doing some time, ive found that we can do much more in DIY than what commercial offerings have out there (aside from a beautiful finishes for speakers above $2k).

 

What is lacking with budget speakers <$2k is BASS, where a sufficient bass response in the room will give you scale, depth and a much less distorting sound in higher SPL (typically 85-90db).

 

for example a 3way consist of 

SB23 8" woofer with excellent performance vs value

 SB-Acoustics-SB23NRXS45-8-HD.gif

SB15 5" midwoofer with offaxis response up to 2.5khz

SB29RDC 1" dome tweeter with usable to 1.7khz

 

if we want to keep sensitivity high, we will need dual 8" woofer. We can see from the simulation the expected performance for the dual 8"

 

cheers

henry

My garage has been the half way house for DIY builds the last month or so :-) ,it's been good theropy .Moving 9 days time and the new place doesn't have a garage or shed so the garage at my parents place & in-laws place will be the new half way houses.one garage for cutting and glueing filling ,one for painting .

We have 8 x AE18 cabs to do ,2x AE6 cabs and one more TH cab .

I forgot the cases for my valve amps an another pair of tube mono blocks

Cheers
