Tube amps with little to No damping (most all of them ?) make full rangers seem to produce far more bass than when SS amp powered.

For every loudspeaker system the amplifier will have an optimum output impedance (damping). The ability to change the FH3 damping is used to adjut the speaker to room, driver, taste, and amplifier.

Your statement applies to all speakers (if we ignore the far to general nature of your comment)

Just a bit of info... I took these to the IowaDIY speaker show on October 18th (SHOW INFO | Midwest Audio Club). This show is attended by some very talented speaker builders. These builders almost always build multi-way speakers. Typically not a lot of interest in single driver configuration. The FH3s were very well received. I think a lot of the regulars were pleasantly surprised by what they heard. In my honest opinion, the FH3's easily held their own against all other speakers. But I'm sure that doesn't come as a surprise. There were two other full range configs this year too: a Cyburg's Needle and a full range with the Dayton PS-220-8 8" driver. All three builds were well received. Not that these need validation, but I just thought some might find it interesting.
I just wanted to pass that on.
 
Just scored some material to build a pair of FH's.

Actually, I bought a foldout couch at Ikea for my daughter's dorm suite and the box it came in would easily make a pair from extra heavy cardboard. I was going to build a pair of Mets for her, but instead built a box out of foamcore that sounds pretty good with a pair of FE126e's in it. I'm going to use my Rat Shack 40-1041 drivers in the Frugels, really just to see how they'll sound. And if it sounds good I have my eyes on the Alpair 7.3.

Maybe I'll build something real someday, I've been on the fence with everything, but time is not on my side. If I can't finish it in an afternoon it just doesn't happen, and not just with audio.
 
$10K???!!

I would be ecstatic if it does better than the 'lowly' KEF LS50 at $1k+ street pricing.

A more or less useless consideration. There are no tandards for this specification, and too much power is better than too little. I generally say minimum 10 w but people are happily using them with 2A3 SE,

As to valur mismatch, you can find $10k speakers on the high street that are not as good as FH3 with A7

I'm finally hearing my FH3 with the Alpair 7.3.

I don't have pictures of building steps because I didn't build. I exchange my pair of MDF 6mm laser cut BR for this already built and some money from a friend who built it, but changed project for 2-way config with bookshelves.

Here's some pictures. First, one of the speakers:

An externally hosted image should be here but it was not working when we last tested it.


The amp: Indeed 2021. Plenty of detail, enough power to drive a party for my apartment hearing levels. I'm pretty satisfied, specially when you look at the nano size of this thing:

And DAC: Fiio E17 with direct Line Out from L7 accessory.

I use to play flacs, or Spotify / Deezer in HQ. Enough for my hearing so far. Soundstage is huge. Detail is intense. Dynamics are excelent. Bass is tight and timbre is close enough from real life.

100% satisfied. My many thanks to Dave, Chris and Mark, who made it possible to listen such a wonder in my leaving room, without expending even 250 bucks for this whole set.

Listening a little carefully to my new babies, and giving a shot in RTA, I have some weird peaks at 60 and 120Hz. How may I make this go away, or being a little softer?

Increasing internal damping? Decreasing? Where?

I have followed the plans, but peaks are there and specially when plaing some natural well recorded jazz contrabass.

Thank you guys.
 
Just to add to toobhed's comment,
Try to move the measurement mic around and see if the peaks shift in frequency.

yes, it's amazing how much difference even a couple of inches can make :eek:


If they do, it's the room interaction, i.e. time to start spending on bass trapping ;)
Most room will dominate the freq response in the region below 150hz...
What do other speakers you've had measure and sound like sited at the same locations?
 
I wasn't thinking about the room. It must be it. Brief description:

Wall behind speakers: flat;
Wall behind listener: Flat;
Celing: Flat;
Floor: Flat, no carpet.
Ledt side: all glass. Flat.
Right side: An 1,8m x 1m library forniture, and rest is opened to the dining room.

It's the worst scenario ever. This speakers are doing an amazing job in such a horrible living room (at least for audio).

I will check the WAF for adding some walls objects, so I broke this flat cube design.

The room is too live, and certainly is doing this boost job at these frequencies.

Chrisb, I don't have other speakers. I was betting so much on A7.3 + FH3 that I gave up of all my previous speakers. And by the way, it was the best thing I could have done. ;)

Thank you guys. I will try to do something here and come back with results... maybe next year. Things here take a long time to get done. haha...
 
Chrisb, as you're visual person as I am, here are some pictures...
