Speaker Enclosure Wiring Question

MrKTrout · 5th February 2012, 05:13 AM

I am interested in building a pair of transmission line (TQWT) speaker enclosures (single-fold Voit pipe) and I have a question regarding the internal wiring between the full range driver and the binding posts. Should the wiring be secured to the inside of the enclosure? I will be using 14 gauge stranded, tinned OFC, 182-strand count.

It doesn't need to be. What FR are you using? For most 14g is quite overkill. We regulatily use 24g solid.

I favor burying it in the stuffing.

The worst-case would be insufficient fastening to enclosure.... it can slap. Only happened to me once, but it drove me mad for a long time until I figured it out.

The FR I'm using is the Merrill DCA5.5 (cast basket) and the enclosure is actually a tapered 8th wave tube design by Ronnie Thackeray of Carolina Audio that was originally for a Feastrex D5NF. I will post pictures as soon as the cabinets are finished.

I never realized that some DCA5.5s were cast basket. Got pictures?

A line may be 1/8th wavelength of something (say Fs?), but as long as one end is closed and one is open it acts as a 1/4 wave resonator.

In general, for the DCA i'd is 20+ g solid wire. What kind of amp are you using?

Here are photos of the cast basket DCA5.5

The amp I will be using is the Charlize2 but I am considering (2) PopPulse T-150Pro TA2022 amps in mono block configuration. By the way, I already own the previous model DCA5.5 (stamped baskets) in custom bass reflex cabinets built by Fritz Heiler of fritzspeakers and they sound amazing. I posted a video on you.tube with the speakers powered by a new Topping TP20 MK2 TA2020 amp: Topping TP20 MK2 TA2020 Tripath Amp - YouTube

Very nice... same basket as the Neophone.

YouTube is not a good venue for showing what something sounds like, and not as good as pictures for what they look like.
