Flush mount screws would solve this problem.
Typical round shaped SpeakOn ones are not an issue. So the measurements you see are with SpeakOn jacks.Īnother minor nit on that note: I had a rather cheap SpeakOn cable and its plug was just large enough to hit the silver screws that the sockets are mounted with. I lost about 3 dB of performance using the banana jacks due to less secure connect there. The SpeakOn are locking and provide the best performance. Using this scheme, the signal to noise ratio can be improved as you will see in measurements later.įor speaker terminals there are two sets: classic heavy duty banana jacks and SpeakOn.

At the other extreme, the low gain setting is designed for professional pre-amps with lots of output, getting its max power at 9.8 volts.

A gain switch allows the input level to be controlled so that you can just use an RCA to XLR adapter and still get full power (2 volt max in high gain). Only input is XLR balanced which is just fine in my book. There is no way I could find an amp capable of handling my speakers properly at that price new.This is a very minimalistic approach given the small amount of real estate available. On the other hand, the XLS2500, cost me only US$250, used. I have an amp capable of 1200W, in a situation where an amp capable of 90W is demonstrably sufficient. taking into account your headroom requirements - and anything beyond that, is never used. So you need to have ENOUGH power to be able to achieve the target SPL in the frequencies that are most difficult (low impedance points / high phase angles). their spec sheet specifies "unconditionally stable into ANY load" - and the power / impedance chart shows that their capacity is but only when you calculate the SPL / Voltage equivalences the is equivalent to around 22.5W 8ohm. However my 1980's vintage Quad 606 amps sound pretty much identical to the Crowns. I run my Gallo Reference 3.2's (which drop down to 1.6ohm) with Crown XLS2500 amps capable of and - yeah they cope with low impedance loads without any issue whatsoever!! Having said that, often it is the amps with massive power that are stable into the low impedance loads!! (which reinforces the massive power myth!) Some amps get unstable at low impedances, other amps just run out of "puff" (current).īut if you calculate out using the SPL efficiency specs for the speaker, you will find that you probably don't need massive power. ThrowRug, SaddleBlankets, WideBand & Bass Traps.Ĭlick to expand.I don't think it (the speaker) actually requires massive power, it just requires massive current, and an amp that is stable at its low impedances.

Yamaha RX-A850 Pro (the other 5 channels lol) PrimaLuna Dialogue Premium TubePre (2 channel+sub) I am looking forward to your impression of the 328Bes. Now that I think of it, I may have to bring 2 AHB2s His system is using an Oppo UDP-105 as the preamp which is a nice solution and has a ML Grotti servo sub which was fairly easy to blend with the F208s without bass management.
He likes it loud and the F208s sound really good in is modest room, 13x15x8. Now that we are both immunized, I am going to setup a listening session with the MiniDSP to compare the AHB2 to the A21 driving these speakers. I bought over a Parasound A21 and level matched and the A21 had no issues at the same volume levels with the tracks we played. I liked these amps at modest volume but not when turned up to where the music was in the mid 80s. The NAD did not do these speaker justice, it got harsh when turned up.Īt home, he had a pair of Outlaw M2200 class-G monoblocks. The room was like a giant pillow, rugs, curtains, suspended ceiling, too dead for my tastes. We auditioned and bought them from a local dealer that drove them with a NAD integrated amp. My brother-in-law bought F206's (maybe 5 years ago). It will be interesting to see how you like these speakers, after experiencing so many.
