I can't remember which speaker project I used this for, but think it was enough for a pr. $25 from Amazon, took almost a month to get though; https://www.amazon.com/gp/product/B08HY53512/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Three differences, New lower price! If I recall correctly, the old cab was around $135. Combined w/ their new, lower free shipping policy of anything over $49 adds more savings. What other hobbies are the prices going down? I might have to turn my HiVi DIY 2.2A's into Totem Forrest clones as...

I've always been a big fan of Curt Campbell's Aviatrix design, both the MT and MTM (never built the MTML/MTL's). Back in 2010, when he first made the design available (he gets my award for "Most Selfless Designer), I built a MTM and two MT's for a LCR frt., scratch building the boxes as this was...

You won't know unless you try it out. My experience is that every source/amp/speaker(s) system combo has a different sound signiture, that old synergy thing. I have an Extron Class D of about the same vintage as your Rotel that works and sound good, but the fact that it's 15 years old and looks...

Yes the features have evolved over the years, but the "mechanics" haven't changed that much. Starting in 2015 when the Dolby Pro Logic IIx was dropped for the Dolby Surround format, they are all simular in function and performance. I have both a RX-A780 and a RX-A860 and I think for streaming...

Hi, I have the RX A770, basicly the same as the V6A and my source most of the time is basic 2-channel PCM and the best format by far, is the Dolby Surround Upmix which converts the 2 channel into multi channel playback (in my case, 7.1.2, 9 speakers). The V4A does not have Dolby Surround Upmix...

First off, I would like to apoligize to the designer, even though I used an air core inductor and purchsed a different port tubes (did not use) and the pre-made PCBs, the entire parts cost was less than $100. Not sure why I thought they were more expensive. Secondly, it was thoughtless of me to...

I used S2000's (TM's) in a desktop system and they are very nice. Their strength is their subdued nature, there's no "in your face" sensation. When I replaced a rather revealing Class D amp (w/ sm. tube hybrid) and upgraded the DAC, I wanted more detail and replaced them w/ 2-ways w/ a full...

Right now, P.E. is not even listing the .23 Ft flat-pack cabnets. I had heard a rumor that they were discontinuing most of the flat-packs, so, for now, they are not an option. The C-note cabs are nice and a smoking deal anyway. I coat the inside of my cab.s with Water Putty. I mix it runny and...

This is somewhat "after the fact", but when Matt Grant designed the Nexus MT, which uses the same woofer and basicly the same box as the C-note, he had to revise the X-over to deal with an "unexpected peak" near 900hz and ended up doing another full set of measurements with a crossover fix for...

I bought a C-note kit as soon as it was aval. and was not impressed w/ the results and they sat around for a couple of years unused. Eventualy, I decided to try and do something w/ them, so I installed the cross-over and tweeter that Matt Grant designed for his NEXUS series of speakers...

You might want to look at the popular Fosi K5 Mini Stereo Gaming DAC. It is a USB powered DAC w/out a remote that is alot of fun in a desktop system and only costs $60. It may not sound not quite as nice as the next tier DACs ($100 and up w/ a remote), depending on the sytem and speakers. It...

Several years ago, Dayton Audio (Parts Express) came out with a line of budget "Hybrid Tube" ampilifiers (the HTABT and HTA series) and this year they dropped the "BT" suffix and changed a few of the features, but they are basicly the same units. The HTA20 is the lowest rated power unit, while...

I run my Extron directly from a DAC, dead silent, even at full gain. Is your receiver and amp plugged into the same outlet?. If so, try seperating them.

Deffinately the 4.7uF on the tweeter. There is enough top-end even for my 71 year old ears and the result sounds very smooth to me. I didn't spend that much time listening to different coils on the woofer. After rotating though the 2.2mH and 2.5mH coils, I went back to the stock coil to see how...

They go into "sleep" mode and draw almost nothing. I just leave mine all the time.

I'm glad Mike is making his X-over's available for nominal cost. As a disappointed builder of the C-notes when they first came out, I contacted Mike when he was offering the documentation for free, thinking I would re-purpose the C-notes, but he never responded. I didn't think much about it, (he...

Comparing DIY to "store bought" speakers is a thorny path to tread. There are just so many factors ranging from cash outlays (Do you own enough tools or will they have to be purchased?) to the really important things like how the S.O. is going to feel about how they look:) It's better to let...

I'm not sure where "here" is, but the V4A doesn't have Altmos or DTS-X and can only up-mix 2-chan content though the Cinema DSP, which I don't enjoy. I find using the Dolby Surround (Dsur) to up-mix to multi-chan to produces a very nice effect. In the States, the lowest cost "refurbished" Altmos...
