NBPK402

Anyone know why I cannot upload a 1MB photo?

I am running my K402MEHs cabinetless (I went back to cabinetless to see if I could get the nice spacious mid and bass and it is def more to my liking...especially since I have a sealed f20 horn sub for each channel) and up until recently with Icepower 50asx2btl and 125asx2btl monos. I decided to try out a pair of the Fosi v3 monoblocks (pair of 10amp power bricks) since they are the rave of the internet for a budget mono amp. I got my first pair in about a month ago and disconnected the Icepower 50asx2btl monos and in with the Fosi V3 (10amp powerbricks), and initially listened and noticed, no horn hiss, more clarity from 500hz up (crossed over at 500hz). They do run hot...so I purchased some heatsinks off of Aliexpress and now they are almost cool to the touch. Since they sounded so good and reviewers say they are excellent on the bottom end too... I decided to order another pair, but this time get the 5amp power bricks (I figured the woofers need the 10amp powerbricks more than the Celextion axi2050 compression drivers). When the new pair arrived, I swapped the inputs and outputs so the new amps with the 5amp powerbricks were on the compression drivers and the woofers were on the 1st pair of v3 monoblocks with 10amp power supplies. Initial impressions are exactly what I expected...same tonality top to bottom (with the icepowers the tonality on the bottom did not match the Fosi v3 top end and was severely lacking in tonality and clarity), now I have excellent clarity from 80hz to 20khz. In addition it made for a better match for my f20 horn subs! I had wondered if the hype was true, and figured 10 year old class D amps compared to the new ones...might be what I needed, and it definitely was.

Sorry...that was my old HT...no pics anymore. What I did was lay the DTS10 on the floor (like the Danley couch sub), and then made a raised floor to cover it. I filled the raised floor with fiberglass and sealed a stainless steel perforated grill to the floor/dts10. I did the same for the 2nd DTS which was under the front stage.

I love my cabinetless MEHs...maybe someday I will replace my celestion woofers and get some real OB woofers.

Wouldn't you measure it with a SPL meter or maybe REW?

New rack almost completed.

Did you solder or crimp your wires? I have not been able to find any female spades that can hold a 12 gauge speaker wire.

@MMurg In your pic of the Celestion axi2050...what kind of connector does it use for your speaker wires? I purchased a pair direct from a Celestion dealer and they have a male spade. I hate the spade and am trying to find out what other connector might be available. I had a Allen's screw type banana jack for attaching to the spade and it is ok, but I would love to be able to have a direct spade or screw terminal instead.

Yamaha 1010 or 2010 integrated or receivers are vintage (late 1970s), and sound great with Klipsch speakers. The one, I had, had a switch on the front to switch to class A too. Class A is nice for low level listening at its best and great for Klipsch speakers!

REWhas a feature i found where can run all your speaker individually and the bring up the phase readout or impulse and you can align each speaker phase or impulse to be the same.

I also need to learn how to align the phase from one speaker to the next in REW.

I am playing around with the crossover point still...currently trying 40hz. I am also running a Harmon curve. Sounds good, and def digs deep! I will be doing some mods to the setup and then retuning.

Here is a closeup to part of the temporary stand...the stand is attached to the k402 horn.

Here is a side shot..you can just barely see the support going to the front and the piece it is attached to, that is screwed to the horn mouth frame.

The speaker grill were some black mesh grills I picked up off of Amazon. The current stands are for temp use and most likely I wil design a new style from the current ones and have them made out of Mesquite hardwood. https://www.amazon.com/uxcell-Speaker-Stereo-Fabric-Dustproof/dp/B07W3J5WX7/ref=sr_1_8?crid=1UGYLQ4J7TPT&keywords=Black+speaker+grill+material&qid=1701968324&sprefix=black+speaker+grill+material%2Caps%2C349&sr=8-8
