    'Headroom' is a measure of the badness of an amplifier. The bigger the number, the worse the amplifier.

    But you are comparing apples to oranges orcas! Only meaningful comparison is amplifier "A" (100W cont., 50W headroom) to amplifier "B" (100W cont., Zero W headroom) - they differ only in their headroom! And Zaphod clearly prefers amplifier "A" with higher headroom: But that contradicts his...

    'Headroom' is a measure of the badness of an amplifier. The bigger the number, the worse the amplifier.

    Lesson on (lack of) logic: First - the premise: OK, then what do you think - which amplifier will sound better: Answer: :facepalm: :facepalm:

    bass guitar speaker cabinet

    Those are hi-fi woofers, which are not suitable for bass-guitar. Sensitivity is low, but the most important is their inability to reach high enough in frequency. This is frequency response of a real bass-driver (Jensen BS 10N/250) for bass guitar: I built a bass-guitar combo with above driver...

    Rogers LS3/5a (BBC) Speaker Review

    So please use them as they are designed. Use airplane for flying and submarine for diving (as they are designed), not vice versa.

    Rogers LS3/5a (BBC) Speaker Review

    It is Sound quality vs price. No, the fifth row is titled Overall - that is "what is the best...". Of course you can get much better speaker for 2475 English pounds, but that is another story...

    Rogers LS3/5a (BBC) Speaker Review

    Theory: The second row in the "stars" table is Value (for the money). Practice: Value for Falcon LS3/5a is 4 stars (should be 1 star). In the first row (Sound) full 5 stars for the same speaker is very questionable, to say the least (should be 1 star).

    Magnepan LRS Speaker Review

    No, all amplifiers do not sound or measure the same - especially if one of them (Audio Analogue Verdi Cento) is a hybrid amplifier (with 10 years old tubes ). Anyway, I will call one of your amplifier suspicious, measurement-wise. Difference of 3 dB is too much, it is on the border of broken...

    Magnepan LRS Speaker Review

    Sonus Faber Grand Piano has elevated high-frequency band and other problems in the critical 2-4 kHz range, so there is no wonder why you like LRS more - your in-room response is very good, indeed.

    Magnepan LRS Speaker Review

    Amplifiers have nothing to do with the frequency response of the loudspeaker (with tone controls on flat, of course). Measure the frequency response of LRS in your room with different amplifiers and you will get exactly the same frequency response.

    Magnepan LRS Speaker Review

    Room is very big factor, I have done many measurements in many customers rooms, while changing speaker positions in a search for the best frequency response at the listening position. But in many rooms, despite all efforts, results were not satisfactory, even with DSP (or software) correction...

    Theoretical - simple stereo amp into speakers of different sensitivity, impedance

    Yes, Power Supply and power output transistors are providing all the necessary juice. Pick your own straw.

    Theoretical - simple stereo amp into speakers of different sensitivity, impedance

    1) No damage to the amplifier, right speaker will be louder. But if there is a balance control, you can adjust both channel to be equally loud. 2) No damage to the amplifier, both speakers will be equally loud.

    That 10" has Neodymium magnet, so of course it is light. Nothing wrong with that.

    8" full range driver paired with woofer for outdoor and indoor movable system

    There is only one lower cost 2-way kit with better sound and comparable/better sensitivity and power handling as Sica 8D1,5CS - that is Volt-8 kit from diysoundgroup: https://www.diysoundgroup.com/home-theater-speaker-kits/volt-8-v2.html but unfortunately it is out of stock and the old price is...

    8" full range driver paired with woofer for outdoor and indoor movable system

    Please share with us which are those 2-way DIY kits for less money. Another way is to buy cheap plastic PA loudspeaker, like: https://www.thomann.de/intl/behringer_pk108.htm#bewertung https://www.thomann.de/intl/fun_generation_pl_110_p.htm

    8" full range driver paired with woofer for outdoor and indoor movable system

    OP clearly is not experienced, so a good 8" fullrange is a sure path to instant success, with very low budget. Of course proper two-way professional loudspeaker will be better, but for a start this is more than enough. I have used Sica 8D1,5CS on numerous occasions with great results for a...
