Just like the topic states.  Does anyone have an opinion on what the best speakers would be to match the Sarah 300B?  About 600 on the list so have time for responding thanks everyone.

I think the SEWE300B would be a good match for many speakers. I have only used one pair: Decware HR-1. I really enjoy the combination. These are amazing speakers. I imagine the new HR-2 are even better.

I’m using Volti Audio Rivals and they sound fabulous played low or loud.  I imagine any similar speaker (e.g., Klipsch Heritage Series) would sound great.

What's been made "obsolete" by his design is the objectionable horn characteristic of horn speakers (cup your hands together around your mouth and talk, and you'll hear the effect).

Yes, I did consider the 15's, and as Eric defined the amp-matching differences between the Perfect SET, Perfect SET15, and 2-10 Perfect SET at the time, the 15 is what would have matched the Sarah the best.

But, the 15 would have locked me into only using a flea-watt tube amp, and if I wanted to go with a higher watt SS amp later, the bass weighting would have been off and I would had to dial back the gain. And, I like using a Sub to overcome room modes, so if the 2-10 was too light on bass, I was going to add some back anyway.

That plan worked great, until things changed. The 2-10s were just a smidge light on bass as expected, I did add bass, and I decided I would very likely never go back to solid state. Then, Eric Alexander introduced the 2-12 Perfect SET, which gives a 5db bump in sensitivity over the 2-10s. So, I sold my 2-10s and got the 2-12s with electronics upgrade and BE tweeters. The bass (for me) is now perfect.

The other reason I didn't go with the P SET15 is that I was told the BE tweeter upgrade was not an option. I would definitely call and speak with Eric Alexander and confirm about the BEs, the difference in fidelity and SQ between one 15 and two 12s, the specific amps you're planning on using, etc. I am highly confident he will steer you in the right direction.

But yes, I think you're on the right track with the bi-amped Perfect SET15s so that you can dial in the bass you prefer.

I'm hoping to pair mine (currently 5th 300B in line on the list, with the first two currently being built!) with my Klipsch La Scala AL5.

I am very much hoping that this amp is quieter than the UFO25 in terms of hum. I'm currently using 2x UFO25s in mono with my La Scalas, and after in depth investigation and discussion with Steve, it would appear that the amount of "built in hum" that the UFO25s have (as a design choice, as explained by Steve), paired with the super high efficiency of my speakers, result in a constant 60 Hz hum that is just a little too loud for me. (and FWIW I did a thorough investigation into the hum and found that all of the hum I'm experiencing is intrinsic to the UFO25s, and is the same from each).

I expect that I'll probably be the first, at least on the forum, to pair the SEWE300B with La Scala AL5s... but just in case anyone else has theirs and has paired it with something that's ~105 dB efficient... any hum?

With great success I have used these speakers with the SEWE300B

GPA (Altec) 604 8H III
Lii Audio F-6s (insane value with some of the best piano laquer finsh I have seen) $415.00 shipped
Decware HDT v II with Lii Audio Silver drivers
Pi Audio Two Pi
TUOLIHAO Q8 V3 (insane value with some of the best lacquer finish ) same to me as Decware T6 to me unless I am shown otherwise and $530.00.

I have no clue how Lii Audio does it but I have heard in person a few as of late. To receive a speaker that couldn't be painted for the cost of a complete shipped speaker would be almost unbelievable if I had not had hands on first hand experience.
