    Amplifiers for bass

    Posed this question in the Owners Clubs, but as it is more general in nature thought I would ask here too. I am looking to bi-amp my speakers using a vertical configuration. I will need an amplifier purely for the bass drivers (12”, sealed boxes). The crossover point between bass and mid is 200hz. The mid/treble will be driven by valves but considering solid state, maybe class D, for the bass (200W should do it). The question I have is, how concerned should I be about the musical qualities of the amp used for the bass? Does it matter as much as for the mids and treble? Also, at what frequency does the tonal colour of an amp become more important? 100-200 hz I would assume is starting to get into the area where bass ceases to be just bass and I may need to consider amps with greater musical subtlety to give a closer match to the valve amp presentation. Thoughts appreciated 👍🏻

    DIY Townsend Seismic Speaker Platform

    I would like to try this style of support under my substantially sized Snell type A speakers (about 45kg each) The real thing now uses springs calibrated for different weights rather than the original air bladders, but they are expensive at £1k plus and s/h prices are firm as well. So, I am going to try and make my own. Thinking of wood instead of metal for the supporting bars, two 90 degree angle brackets bolted to form an S shape for the outriggers and contemplating mountain bike suspension struts for the damping. Any one else tried something like this? In particular, the springs and housing look the most complex, how would you tackle this?

    Got my springs as well this week after calling them on Monday. Pictures to follow later today when I start to put all the pieces together.

    Hopefully will be having a Vitus class A coming over for a visit soon so this will give me a good opportunity to compare. My Snells have an unusual driver array in that the 12” bass hands over to a 4” mid. With the 4” picking up at just 200hz careful matching is needed to flesh out the first few hundred hz otherwise the sound can be too thin leaving the upper mids exposed.

    Ah, but I have heard the Snells on the end of solid state and the mids are too forward for me. Valves give a much better balanced presentation. I am agnostic, even leaning towards SS for bass.

    I like that, even has valves by the look of it. No RCA input on this model so would need converting.

    Some great feedback so far, thanks. There seems to be some consensus building around DSP as giving the best flexibility but, however irrationally, I am not keen on adding digital to the signal. comments on quality of the amplification stick in my mind but also we have fans of class D. If I am doing this using the existing crossovers it looks like I will need to get an amp that matches the gain of my valve amp. I am a little way off though at the moment, need to get a pre as well as well as converting or changing the integrated valve amp. So more exploring future possibilities. This is taken from the Sterophile review of my speakers in 1984. They describe the bass (using a Mark Levenson amp) as follows: “The large drum...causes an amazingly percussive sound, percussive in the true sense of the word: a steep wavefront followed by a sledgehammer sensation of solidity and impact” Now that’s what we are aiming for folks!

    Appreciate your thoughts, that’s helpful. might adjustable attenuation be possible in the RCA cable?

    JBL K2 9800

    I am sure I have a hard copy of the review of the 9800’s done by Paul Messenger in HiFi + if that is of interest. He was very smitten and as such they have been on my radar for a ‘would love to hear’ for years.

    Yes, let’s do that. I’ll see if Gabriel and Ian are up for a session as well. I’ll send a PM

    Amplifiers for bass

    I would like the bass power amp(s) to have an adjustable gain - not only in order that I can set the ideal amount for the valve amp/speaker/room combination but also so it can be dialled down for late night listening / to give neighbours a break etc

    Snell Speakers

    Contemplating bi-amping the Snells - horizontal configuration. The crossovers are already set up for this within the speakers. Valve is definitely the way to go with mids and treble but considering solid state for the bass. Bass unit is a 12” downward firing unit in a sealed enclosure. The crossover is set at 200hz. i need power, lots of power, and moderately priced Class D looks interesting. Considering the crossover point, should I be concerned about the quality of the watts and it’s potential integration with the timbre of the valve driven mids or is bass just bass? Any thoughts?

    Homemade ultrasonic vinyl cleaner

    One other thought. If you are ripping to digital you may find there are some tools available that can minimise pops and clicks on the digital copy.

    Homemade ultrasonic vinyl cleaner

    General consensus seems to be that ultrasonic does give a deeper clean than traditional brush & vacuum method, but the vacuum has an advantage in drying and removing residue. With both machines you can utilise the best of both. Pops and clicks can be down to surface damage though and cleaning won’t solve this. Looks like you have dance 12” records, if these have been dj’d or less sympathetically handled then you may have to accept that they will never be perfectly quiet.

    I agree, ultrasonic is the way to go with records in this condition and you have a decent chance of success. Spiders machines are great value compared to other commercially available ones. If it is an consolation your records look in better condition than a friend of mine’s. He was an avid record collector but had a dispute with his father and had to leave home leaving his collection behind. 25 years later and after his father had died, he found they had been dumped in a leaking outhouse. The records have fused together into one evil smelling lump. Apparently, amongst other rarities encased, there are two copies of Nirvana’s first 7” - he has a harrowed look when he mentions checking on Discogs.

    What's the point?

    Largely due to the Fashion for narrow baffles - which also affects floor-standers. It also introduces compromises on the size of the drivers with 6 1/2” being usual maximum. This in turn often means ported cabinets to produce the required bass as opposed to sealed - another compromise IMHO.

    Denon HA500 Head Amp

    Out of interest, did you try this with your Vida? Must admit I am still getting up to speed with trying to understand all the SUT / head amp complexities, but I guess you could feed an MC cart into this and then to the MM input in the Vida. I ask because a) I have a Vida, and b) I read somewhere that the Vida can sound even better in this configuration.

    What's the point?

    I had a TT as a teenager that was technically capable of this. It didn’t actually have a shuffle button but you could select or skip tracks with the press of a button. recently restored by Graham - take a look

    What's the point?

    Actually no, random shuffle is more like double jeopardy in this situation- you never know when he is about to ding a ling!

    Vinyl is a life’s journey

    Initial reaction to this was, yeah I can understand exactly the spirit the OP is trying to convey, but remember when every record was bought - no way. Thing is I am now looking at my records and it’s amazing how many I can still picture pulling out of the rack in the record store. Some chance purchases others researched and eagerly sought out. Each with a tingle of anticipation. Ainleys and Rockaboom in Leicester, special trips to the awesome Select-a-disc in Nottingham, second hand rarity shopping in Soho - it all floods back. For so long it has seemed a lost point in time, but going to Rough Trade East a couple of weeks ago is like time travelling back 20 years, wall to wall vinyl and I can spend a happy hour (or two) flicking the racks and taking my carefully selected choices to the till. Vinyl rules, OK!?
