TL606 built 1.5 inches narrower- What now?
Was building my first 606 for use with 800rb and Basslite 15" speaker. While fitting the bottom I realized that the cabinet was 1.5 inches narrower than the plans. I used standard bracing (screwed and glued...not coming apart.) and made port height 2.5 inches instead of 2". The baffle has not yet been cut.
Can I still use cab for 15" as intended? What do you recommend?
That isn't all that mch volume lost. Could either just make the ports slightly shorter, mayhe 1/2"? Or add it back in height if you can saw the top off, extend sides and re-attach.
Think it will work out
Thanks for the replys. If my math is right:
- I lost 1.5 inches in width/volume which still keeps overall cab volume within range for the intended speaker.
-Because I made the vent height 2.5 instead of 2" I only decreased overall vent size by small amount.
Going to finish cab and instal speaker. Stay tuned!
Changing the cab volume by a small amount won't make much difference. I suggest making the vent "adjustable" in some fashion, for instance temporarily installing the vent wall with some screws. Then you can measure the port tuning frequency and adjust as needed. When you're happy, finish up with glue.
You can measure the port tuning with a few grains of (uncooked) rice on the cone, and a signal generator such as is found in the nice free program Visual Analyzer. The rice will dance on the cone, and will stop dancing when the generator is set to the tuning frequency of the port.
Horseshoes and hand grenades and TL 606's, close is good.
I've made them with taller port runners (3") for a bigger port, but capped the center section. It's a pretty flexible and forgiving design.
Button it up and plug it in!
I was sure I would get very useful input, and I did! Thanks.
And another thing
Stuffing the box with wool, fiberglass, polyester fiber or foam can increase the apparent/effective volume. Do a little search on speaker stuffing and you will soon be awash in information. Do not block the port with stuffing. Help is as near as your nearest fabric store.
